1.4 CE Compliance

Equipment is generally divided into two classes.

CLASS A CLASS B

Digital equipment meant for light industrial use Digital equipment meant for home use

Less restrictive emissions requirement:
less than 40 dB µV/m at 10 m
(40 dB relative to 1 µV/m) or 300 µV/m

More restrictive emissions requirement:
30 dB µV/m at 10 m or 100 µV/m

These limits apply over the range of 30–230 MHz. The limits are 7 dB higher for frequen­cies above 230 MHz. Although the test range goes to 1 GHz, the emissions from Rabbit­based systems at frequencies above 300 MHz are generally well below background noise
levels.

The BL2600 single-board computer has been tested and was found to
be in conformity with the following applicable immunity and emission
standards. The BL2610 single-board computer is also CE qualified as it
is a sub-version of the BL2600 single-board computer. Boards that are
CE-compliant have the CE mark.

NOTE: Earlier versions of the BL2600 that do not have the CE mark are not CE-compliant.

Immunity

The BL2600 series of single-board computers meets the following EN55024/1998 immu­nity standards.

• EN61000-4-3 (Radiated Immunity)

• EN61000-4-4 (EFT)

• EN61000-4-6 (Conducted Immunity)

Additional shielding or filtering may be required for a heavy industrial environment.

Emissions

The BL2600 series of single-board computers meets the following emission standards.

• EN55022:1998 Class B

• FCC Part 15 Class B

Your results may vary, depending on your application, so additional shielding or filtering
may be needed to maintain the Class B emission qualification.

6 SBC BL2600

1.4.1 Design Guidelines

Note the following requirements for incorporating the BL2600 series of single-board
computers into your application to comply with CE requirements.

General

• The power supply provided with the Tool Kit is for development purposes only. It is the

customer’s responsibility to provide a CE-compliant power supply for the end-product
application.

• When connecting the BL2600 single-board computer to outdoor cables, the customer is

responsible for providing CE-approved surge/lightning protection.

• Rabbit recommends placing digital I/O or analog cables that are 3 m or longer in a

metal conduit to assist in maintaining CE compliance and to conform to good cable
design practices.

• When installing or servicing the BL2600, it is the responsibility of the end-user to use

proper ESD precautions to prevent ESD damage to the BL2600.

Safety

• All inputs and outputs to and from the BL2600 series of single-board computers must

not be connected to voltages exceeding SELV levels (42.4 V AC peak, or 60 V DC).

• The lithium backup battery circuit on the BL2600 single-board computer has been

designed to protect the battery from hazardous conditions such as reverse charging and
excessive current flows. Do not disable the safety features of the design.

1.4.2 Interfacing the BL2600 to Other Devices

Since the BL2600 series of single-board computers is designed to be connected to other
devices, good EMC practices should be followed to ensure compliance. CE compliance is
ultimately the responsibility of the integrator. Additional information, tips, and technical
assistance are available from your authorized Rabbit distributor, and are also available on
our Web site at www.digi.com.

1. Connect the programming cable to download programs from your PC and to program
and debug the BL2600.

NOTE: Use only the programming cable that has a blue shrink wrap around the RS-232

level converter (Part No. 101-0542). If you are using a BL2610, which is based on the
RCM3100, you will need the programming cable that has a red shrink wrap around the
RS-232 level converter (Part No. 101-0513). Other programming cables are not
voltage-compatible or their connector sizes may be different.

Connect the 10-pin PROG connector of the programming cable to header J3 on the
BL2600’s RabbitCore module (the programming header is labeled J1 on special-edition
BL2600s based on the RCM3365/RCM3375). Ensure that the colored edge lines up with
pin 1 as shown. (Do not use the DIAG connector, which is used for monitoring only.) Con­nect the other end of the programming cable to a COM port on your PC. Make a note of
the port to which you connect the cable, as Dynamic C will need to have this parameter
configured. Note that COM1 on the PC is the default COM port used by Dynamic C.

NOTE: Some PCs now come equipped with a USB port only. It may be possible to use

10 SBC BL2600

an RS-232/USB converter (Part No. 20-151-0178) with the programming cables men­tioned above. Note that not all RS-232/USB converters work with Dynamic C.

Figure 3. Programming Cable Connections

2. When all other connections have been made, you can connect power to the BL2600.

First, prepare the AC adapter for the country where it will be used by selecting the plug.
The BL2600 Tool Kit presently includes Canada/Japan/U.S., Australia/N.Z., U.K., and
European style plugs. Snap the top of the plug assembly into the slot at the top of the
AC adapter as shown in Figure 4, then press down on the spring-loaded clip below the
plug assembly to allow the plug assembly to click into place.

Connect the AC adapter to header J12 on the BL2600 as shown in Figure 4. You can
use the crimps and the friction-lock connector included in the Tool Kit to connect the
leads from the power supply, then match the friction lock tab on the friction-lock con­nector to the back of header J12 on the BL2600 as shown. The friction-lock connector
will only fit one way.

Figure 4. Power Supply Connections

3. Apply power.

Plug in the AC adapter. The power LED will light up when the BL2600 is powered up
correctly.

CAUTION: Unplug the AC adapter while you make or otherwise work with the connections

to the headers. This will protect your BL2600 from inadvertent shorts or power spikes.

2.2.1 Hardware Reset

A hardware reset is done by unplugging the ACV adapter, then plugging it back in, or by
pressing the RESET button located just above the RabbitCore module.

User’s Manual 11

2.3 Installing Dynamic C

If you have not yet installed Dynamic C version 8.51 (or a later version), do so now by
inserting the Dynamic C CD from the BL2600 Tool Kit in your PC’s CD-ROM drive. The
CD will auto-install unless you have disabled auto-install on your PC.

If the CD does not auto-install, click Start > Run from the Windows Start button and
browse for the Dynamic C setup.exe file on your CD drive. Click OK to begin the
installation once you have selected the setup.exe file.

The online documentation is installed along with Dynamic C, and an icon for the docu­mentation menu is placed on the workstation’s desktop. Double-click this icon to reach the
menu. If the icon is missing, create a new desktop icon that points to default.htm in the

docs folder, found in the Dynamic C installation folder.

The latest versions of all documents are always available for free, unregistered download
from our Web sites as well.

The Dynamic C User’s Manual provides detailed instructions for the installation of
Dynamic C and any future upgrades.

NOTE: If you have an earlier version of Dynamic C already installed, the default instal-

lation of the later version will be in a different folder, and a separate icon will appear on
your desktop.

Once your installation is complete, you will have up to three icons on your PC desktop.
One icon is for Dynamic C, one opens the documentation menu, and the third is for the
Rabbit Field Utility, a tool used to download pre-compiled software to a target system.

If you have purchased any of the optional Dynamic C modules, install them after installing
Dynamic C. The modules may be installed in any order. You must install the modules in
the same directory where Dynamic C was installed.

12 SBC BL2600

2.4 Starting Dynamic C

Once the BL2600 is connected to your PC and to a power source, start Dynamic C by
double-clicking on the Dynamic C icon on your desktop or in your Start menu.

If you are using a USB port to connect your computer to the BL2600, choose Options >

Project Options
Communications tab. Click OK to save the settings.

If you are using a BL2600 model running at 44.2 MHz, set the compiler to run the applica­tion in the fast program execution SRAM by selecting “Code and BIOS in Flash, Run in
RAM” in the “BIOS Memory Setting” on the Compiler tab under the Options > Project

Options

menu. Click OK to save the settings.

Dynamic C defaults to using the serial port on your PC that you specified during installa­tion. If the port setting is correct, Dynamic C should detect the BL2600 and go through a
sequence of steps to cold-boot the BL2600 and to compile the BIOS. (Some versions of
Dynamic C will not do the initial BIOS compile and load until the first time you compile a
program.)

If you receive the message No Rabbit Processor Detected, the programming
cable may be connected to the wrong COM port, a connection may be faulty, or the target
system may not be powered up. First, check both ends of the programming cable to ensure
that it is firmly plugged into the PC and the programming port.

and check “Use USB to Serial Converter” in “Serial Options” on the

If there are no faults with the hardware, select a different COM port within Dynamic C.
On your computer, open Control Panel > System > Hardware > Device Manager >

Ports

and look at the list of available COM ports. In Dynamic C, select Options > Proj-

ect Options

, then select one of these available COM ports on the Communications tab,
then click OK. Press <Ctrl-Y> to force Dynamic C to recompile the BIOS. If Dynamic C still
reports it is unable to locate the target system, repeat the above steps for another available
COM port. You should receive a Bios compiled successfully message once this
step is completed successfully.

If Dynamic C appears to compile the BIOS successfully, but you then receive a communi­cation error message when you compile and load a sample program, it is possible that your
PC cannot handle the higher program-loading baud rate. Try changing the maximum
download rate to a slower baud rate as follows.

• Locate the Serial Options dialog in the Dynamic C Options > Communications

menu. Select a slower Max download baud rate. Click OK to save the settings.

If a program compiles and loads, but then loses target communication before you can
begin debugging, it is possible that your PC cannot handle the default debugging baud
rate. Try lowering the debugging baud rate as follows.

• Locate the Serial Options dialog in the Dynamic C Options > Communications

menu. Choose a lower debug baud rate. Click OK to save the settings.

User’s Manual 13

2.5 PONG.C

You are now ready to test your set-up by running a sample program.

Find the file PONG.C, which is in the Dynamic C SAMPLES folder. To run the program,
open it with the File menu (if it is not still open), compile it using the Compile menu, and
then run it by selecting Run in the Run menu. The STDIO window will open and will dis­play a small square bouncing around in a box.

This program shows that the CPU is working. The sample program described in
Section 5.2.3, “Run the PINGME.C Demo,” tests the TCP/IP portion of the board.

2.6 Where Do I Go From Here?

NOTE: If you purchased your BL2600 through a distributor or Rabbit partner, contact

the distributor or partner first for technical support.

If there are any problems at this point:

• Use the Dynamic C Help menu to get further assistance with Dynamic C.

• Check the Rabbit Technical Bulletin Board and forums at www.rabbit.com/support/bb/

and at www.rabbit.com/forums/.

• Use the Technical Support e-mail form at www.rabbit.com/support/questionSubmit.shtml.

If the sample program ran fine, you are now ready to go on to explore other BL2600 fea­tures and develop your own applications.

Chapter 3, “Subsystems,” provides a description of the BL2600’s features, Chapter 4,
“Software,” describes the Dynamic C software libraries and introduces some sample pro­grams, and Chapter 5, “Using the TCP/IP Features,” explains the TCP/IP features.

3.1.1 Connector Options

Standard BL2600 models are equipped with two 1 × 20 friction-lock connector terminals
(J1 and J2), two polarized 1 × 10 friction-lock connector terminals (J8 and J15) where pin 9
is removed to polarize the connector terminals, one 1 × 13 friction-lock connector terminal
(J16), and one 1 × 10 friction-lock connector terminal (J17); all of these friction-lock con­nector terminals have a 0.1" pitch.

Two 4-pin 0.156" friction-lock connector terminals at J5 and J7 are installed to supply
power (DCIN and +5 V) to the RabbitNet peripheral expansion boards. The 4-pin 0.156"
friction-lock connector terminal at J12 is for the main power supply connections.

Table 3 lists Molex connector part numbers for the crimp terminals, housings, and polarizing
keys needed to assemble female friction-lock connector assemblies for use with their male
counterparts on the BL2600.

3.2.1 Digital Inputs

The BL2600 has 16 digital inputs, DIN16–DIN31, each of which is protected over a range
of –36 V to +36 V. The inputs are factory-configured to be pulled up to +5 V, but they can
also be pulled up to +K or DCIN, or pulled down to 0 V in banks by changing a jumper as
shown in Figure 7.

CAUTION: Do not simultaneously jumper more than one setting on a particular
jumper header (JP3, JP4, and JP5) when configuring a bank of digital inputs.

Figure 7. BL2600 Digital Inputs DIN16–DIN31 [Pulled Up—Factory Default]

Table 4 lists the banks of digital inputs and summarizes the jumper settings.

PWM Outputs

3.2.2 PWM Outputs

Digital inputs DIN20–DIN23 can be used as PWM output channels by setting the jumper
on header JP4 across pins 7–8 to pull the digital inputs to ground. Once the PWM driver
sets up a given PWM channel, the corresponding digital input channel is no longer avail­able for use as a digital input. The output voltage swing will be 0 to 1.65 V, which is not
suitable for interfacing only to CMOS-level inputs. Since the output impedance is approx­imately 13 k, the input impedance of the circuit the PWM output is connected to should
be at least 10 times as high.

The sample program PWM.C in the IO subdirectory in SAMPLES\BL2600 shows how to
set up and use the PWM outputs.

The BL2600 has four high-current digital outputs, HOUT0–HOUT3, which can each sink
or source up to 2 A. Figure 9 shows a wiring diagram for using the digital outputs in either
a sinking or a souring configuration.

Figure 9. BL2600 High-Current Digital Outputs

All the digital outputs sink and source actively. They can be used as high-side drivers, low­side drivers, or as an H-bridge driver. When the BL2600 is first powered up or reset, all
the outputs are disabled, that is, at a high-impedance tristate, until the digHoutConfig
software function call is made. The digHoutConfig call sets the initial state of each
high-current output according to the configuration specified by the user, and enables the
digital outputs to their initial status.

CAUTION: If you are using a BL2600 with the IDC header connectors, beware that
an individual IDC header pin can only handle up to 1 A. Since the same high-current
outputs are available on opposite pairs of IDC header connectors, you can still use the
2 A sinking or sourcing capability of the BL2600 by wiring all your connections,
including the ground, in parallel to the opposite pairs (see Figure 10 for an example).

The BL2600 has 16 configurable I/O that may be configured individually in software as
either digital inputs or as sinking digital outputs. By default, a configurable I/O channel is
a digital input, but may be set as a sinking digital output by using the digOutConfig
function call. The inputs are factory-configured to be pulled up to +5 V, but they can also
be pulled up to +K or DCIN, or pulled down to 0 V in banks by changing a jumper as
shown in Figure 12.

CAUTION: Do not simultaneously jumper more than one setting on a particular
jumper header (JP1 and JP2) when configuring a bank of configurable I/O.

DIO08–DIO15 JP2 3–4 Inputs pulled up to DCIN

5–6 Inputs pulled up to +K

7–8 Inputs pulled down to GND

As for the nonconfigurable digital inputs, the actual switching threshold is approximately

1.40 V. Anything below this value is a logic 0, and anything above is a logic 1. The digital
inputs are each fully protected over a range of -36 V to +36 V, and can handle short spikes
of ±40 V.

NOTE: If the inputs are pulled up to +K or to DCIN, the voltage range over which

the digital inputs are protected changes to +K (or DCIN) – 36 V to +36 V.

When set as a sinking digital output, a configurable I/O channel can sink up to 200 mA at
up to 40 V. When you use the software digOutConfig function call to set the configu­rable I/O, DIO00–DIO15 are considered to be digital output channels 00–15. The output
can be set up either as a sinking output or it can be put in a high-impedance tristate.

When a configurable I/O is configured
as a sinking output, be sure to connect
an external voltage source up to 36 V
DC across +K and GND on header
J1/J3, and set the pullup jumper on the
corresponding JP1/JP2 header to +K.

3.3 Serial Communication

The BL2600 has three serial communication ports, which can be configured as one RS-232
serial channel (with RTS/CTS) and one RS-232 (3-wire) channel or one RS-485 channel, or
as three RS-232 (3-wire) channels, or as two RS-232 (3-wire) channels and one RS-485
channel by using the serMode software function call. Table 8 summarizes the options.

0 RS-232, 3-wire RS-232, 3-wire RS-232, 3-wire

1 RS-232, 3-wire RS-485 RS-232, 3-wire

2 RS-232, 5-wire RS-232, 3-wire CTS/RTS

3 RS-232, 5-wire RS-485 CTS/RTS

The BL2600 also has one CMOS serial channel that serves as the programming port.

All four serial ports operate in an asynchronous mode. An asynchronous port can handle 7
or 8 data bits. A 9th bit address scheme, where an additional bit is sent to mark the first
byte of a message, is also supported. Serial Port A, the programming port, can be operated
alternately in the clocked serial mode. In this mode, a clock line synchronously clocks the
data in or out. Either of the two communicating devices can supply the clock. The BL2600
boards typically use all four ports in the asynchronous serial mode. Serial Ports C and F
are used for RS-232 communication, and Serial Port E is used for RS-232 or RS-485 com­munication. The BL2600 uses a 22.12 MHz resonator, which is doubled to 44.2 MHz. At
this frequency, the BL2600 supports standard asynchronous baud rates up to a maximum
of 5.525 Mbps.

3.3.1 RS-232

The BL2600 RS-232 serial communication is supported by an RS-232 transceiver. This
transceiver provides the voltage output, slew rate, and input voltage immunity required to
meet the RS-232 serial communication protocol. Basically, the chip translates the Rabbit
3000’s CMOS signals to RS-232 signal levels. Note that the polarity is reversed in an
RS-232 circuit so that a +3.3 V output becomes approximately -10 V and 0 V is output as
+10 V. The RS-232 transceiver also provides the proper line loading for reliable commu­nication.

RS-232 can be used effectively at the BL2600’s maximum baud rate for distances of up to
15 m.

3.3.2 RS-485

The BL2600 can be set for one RS-485 serial channel, which is connected to the Rabbit
3000 Serial Port E through an RS-485 transceiver. The half-duplex communication uses
the Rabbit 3000’s PE3 pin to control the transmit enable on the communication line.

The BL2600 comes with a 220  termination resistor and two 681  bias resistors installed
and enabled with jumpers across pins 1–2 and 5–6 on header JP7, as shown in Figure 15.

Figure 15. RS-485 Termination and Bias Resistors

For best performance, the bias and termination resistors in a multidrop network should
only be enabled on both end nodes of the network. Disable the termination and bias resis­tors on any intervening BL2600 units in the network by removing both jumpers from
header JP6.

TIP: Save the jumpers for possible future use by “parking” them across pins 1–3 and 4–6

of header JP7. Pins 3 and 4 are not otherwise connected to the BL2600.

3.3.3 Programming Port

The RabbitCore module on the BL2600 has a 10-pin programming header. The program­ming port uses the Rabbit 3000’s Serial Port A for communication, and is used for the fol­lowing operations.

• Programming/debugging

• Cloning

The programming port is used to start the BL2600 in a mode where the BL2600 will
download a program from the port and then execute the program. The programming port
transmits information to and from a PC while a program is being debugged.

The Rabbit 3000 startup-mode pins (SMODE0, SMODE1) are presented to the program­ming port so that an externally connected device can force the BL2600 to start up in an
external bootstrap mode. The BL2600 can be reset from the programming port via the

/EXT_RSTIN line.

The Rabbit 3000 status pin is also presented to the programming port. The status pin is an
output that can be used to send a general digital signal.

NOTE: Refer to the Rabbit 3000 Microprocessor User’s Manual for more information

related to the bootstrap mode.

The single A/D converter chip used in the BL2600 has a resolution of 12 bits (11 bits for the

Each external input has circuitry that provides scaling and filtering. All 8 external inputs
are scaled and filtered to provide the user with an input impedance of 1 M and a variety
of single-ended unipolar, single-ended bipolar, and differential bipolar ranges as shown in
Table 9.

Figure 17 shows a pair of A/D converter input circuits. The resistors form an approx. 10:1
attenuator, and the capacitors filter noise pulses from the A/D converter inputs.

. The A/D converter chip has a programmable amplifier.

Figure 17. Buffered A/D Converter Inputs

The A/D converter chip can only accept positive voltages. By pairing the analog inputs and
setting the reference voltage from the D/A converter [0 V for single-ended unipolar or dif­ferential measurements, V = (voltage range) ÷ 9 for single-ended bipolar measurements],
single-ended unipolar, single-ended bipolar, differential bipolar, or current (4–20 mA on
channels 0–3 only) measurements are possible, and can be configured for each channel or
channel pair with the opmode parameter in the anaInConfig software function call.
Adjacent A/D converter inputs are paired to make bipolar measurements. The default

3.4.1 A/D Converter Calibration

To get the best results form the A/D converter, it is necessary to calibrate each mode (sin­gle-ended, differential, and current) for each of its gains. It is imperative that you calibrate
each of the A/D converter inputs in the same manner as they are to be used in the applica­tion. For example, if you will be performing floating differential measurements or differ­ential measurements using a common analog ground, then calibrate the A/D converter in
the corresponding manner. The calibration table in software only holds calibration con­stants based on mode, channel, and gain. Other factors affecting the calibration must be taken

into account by calibrating using the same mode and gain setup as in the intended use.

Sample programs are provided to illustrate how to read and calibrate the various A/D

The four D/A converter outputs are buffered and scaled to provide an output from 0 V to
+10 V (12-bit resolution) or ±10 V (11-bit resolution, one bit used for polarity). There are
also four 4–20 mA current outputs. Figure 18 shows the D/A converter outputs.

Figure 18. D/A Converter Outputs

To stay within the maximum power dissipation of the D/A converter circuit, the maximum
D/A converter output current is 10 mA per channel for the voltage outputs. If you are
using the current outputs, keep the resistance driven by a current output channel below
400  to stay within the voltage compliance capability of the op-amp output circuit.

As Figure 18 shows, both the voltage and the current outputs for a particular channel are
driven by the same output on the D/A converter chip. As a result, either the anaOutVolts
or the anaOutmAmps function calls will set both the voltage and the current outputs corre­sponding to a particular channel. For example, if anaOutVolts sets unipolar channel
AV0 to be +10 V, AI0 will be 20 mA; if anaOutVolts sets unipolar channel AV0 to be
+5 V, AI0 will be 12 mA, the midpoint of the 4–20 mA range. It is possible to connect a
load to both the corresponding voltage and current outputs as long as the combined current
consumption does not exceed the 20 mA individual limit.

Because of the “connection” between the analog voltage outputs and the analog current
outputs, the configuration of the analog voltage outputs with the anaOutConfig function
call as unipolar outputs with 12-bit resolution or as bipolar outputs with 11-bit resolution

User’s Manual 31

also affects the resolution of the 4–20 mA current outputs—you need to configure a volt­age output for unipolar operation if you want 12-bit resolution on the associated current
output.

There are other effects on a current output when the associated voltage output is operating
in the bipolar mode. While voltages of 0 to +10 V still correspond to currents of 4 to 20 mA,
the current cannot be determined reliably for voltages below 0 V, and will be “negative” at
voltages below -2.5 V. Thus the current output effectively becomes a “current sink”
instead of a “current source.”

The D/A converter outputs are factory-calibrated and the calibration constants are stored in a
separate EEPROM.

3.5.1 D/A Converter Calibration

To get the best results form the D/A converter, it is necessary to calibrate each mode (uni­polar, bipolar, and current) for each of its gains. It is imperative that you calibrate each of
the D/A converter outputs in the same manner as they are to be used in the application.
The calibration table in software only holds calibration constants based on unipolar, bipo­lar, and voltage or current operation. Other factors affecting the calibration must be taken into

account by calibrating using the same mode and voltage/current setup as in the intended use.

The A/D converter chip supplies the 2.048 V reference voltage, which is divided in half
and then amplified and buffered to provide the 1.667 V and 2.5 V reference voltages used
by the digital output circuits.

The D/A converter chip provides the reference voltages for the digital inputs to provide
single-ended unipolar or differential measurements [0 V], or to provide single-ended
bipolar measurements [V = (voltage range) ÷ 9]. Because the D/A converter chip operation
is configured by the anaOutConfig function, it is important to run the anaOutConfig
function before running anaInConfig if you plan to use the digital outputs to ensure that
the reference voltages are established first before the analog inputs are configured.

Run Mode

Programming Cable

DIAG

PROG

Colored edge

To

PC COM port

The programming cable is used to connect the serial programming port of the BL2600 to a
PC serial COM port. The programming cable converts the RS-232 voltage levels used by
the PC serial port to the CMOS voltage levels used by the Rabbit 3000.

When the PROG connector on the programming cable is connected to the programming
header on the BL2600’s RabbitCore module, programs can be downloaded and debugged
over the serial interface.

The DIAG connector of the programming cable may be used on the programming header on
the BL2600’s RabbitCore module with the BL2600 operating in the Run Mode. This
allows the programming port to be used as a regular serial port.

3.7.1 Changing Between Program Mode and Run Mode

The BL2600 is automatically in Program Mode when the PROG connector on the pro­gramming cable is attached, and is automatically in Run Mode when no programming
cable is attached. When the Rabbit 3000 is reset, the operating mode is determined by the
status of the SMODE pins. When the programming cable’s PROG connector is attached,
the SMODE pins are pulled high, placing the Rabbit 3000 in the Program Mode. When the
programming cable’s PROG connector is not attached, the SMODE pins are pulled low,
causing the Rabbit 3000 to operate in the Run Mode.

A program “runs” in either mode, but can only be downloaded and debugged when the
BL2600 is in the Program Mode.

Refer to the Rabbit 3000 Microprocessor User’s Manual for more information on the pro­gramming port and the programming cable.

Figure 20. BL2600 Program Mode and Run Mode Setup

3.8 Other Hardware

3.8.1 Clock Doubler

The BL2600 takes advantage of the Rabbit 3000 microprocessor’s internal clock doubler.
A built-in clock doubler allows half-frequency crystals to be used to reduce radiated emis­sions. The 44.2 MHz frequency specified for the BL2600 is generated using a 22.12 MHz
resonator, and the 29.4 MHz frequency specified for the BL2610 is generated using a

14.7456 MHz crystal.

The clock doubler may be disabled if the higher clock speeds are not required. Disabling
the Rabbit 3000 microprocessor’s internal clock doubler will reduce power consumption
and further reduce radiated emissions. The clock doubler is disabled with a simple config­uration macro as shown below.

1. Select the “Defines” tab from the Dynamic C Options > Project Options menu.

2. Add the line CLOCK_DOUBLED=0 to always disable the clock doubler.

The clock doubler is enabled by default, and usually no entry is needed. If you need to
specify that the clock doubler is always enabled, add the line CLOCK_DOUBLED=1 to
always enable the clock doubler.

3. Click OK to save the macro. The clock doubler will now remain off whenever you are
in the project file where you defined the macro.

3.8.2 Spectrum Spreader

The Rabbit 3000 features a spectrum spreader, which helps to mitigate EMI problems. By
default, the spectrum spreader is on automatically, but it may also be turned off or set to a
stronger setting. The means for doing so is through a simple configuration macro as shown
below.

1. Select the “Defines” tab from the Dynamic C Options > Project Options menu.

2. Normal spreading is the default, and usually no entry is needed. If you need to specify nor­mal spreading, add the line

ENABLE_SPREADER=1

For strong spreading, add the line

ENABLE_SPREADER=2

To disable the spectrum spreader, add the line

ENABLE_SPREADER=0

NOTE: The strong spectrum-spreading setting is not recommended since it may limit

the maximum clock speed or the maximum baud rate. It is unlikely that the strong set­ting will be used in a real application.

3. Click OK to save the macro. The spectrum spreader will now remain off whenever you are

in the project file where you defined the macro.

NOTE: Refer to the Rabbit 3000 Microprocessor User’s Manual for more information

on the spectrum-spreading setting and the maximum clock speed.

3.9.1 SRAM

The BL2600 modules running at clock speeds of 44.2 MHz have 512K of program­execution SRAM. All the BL2600 modules have 256K–512K of data SRAM.

3.9.2 Flash Memory

The BL2600 also has 512K of flash memory.

NOTE: Rabbit recommends that any customer applications should not be constrained by

the sector size of the flash memory since it may be necessary to change the sector size
in the future.

Writing to arbitrary flash memory addresses at run time is also discouraged. Instead,
define a “user block” area to store persistent data. The functions writeUserBlock and

readUserBlock are provided for this.

A Flash Memory Bank Select jumper configuration option based on 0  surface-mounted
resistors exists at location JP4 on the RabbitCore module (BL2600) or at location JP1 on
the RabbitCore module (BL2610). These options are reserved for future use.

3.9.3 Serial Flash

Socket J9 is provided to allow you to plug in an optional Rabbit SF1000 serial flash via
Serial Port D. You may use two 0.375" (9.5 mm) spacers with 4-40 × 3/4 screws and nuts
to attach the SF1000 securely.

The RCM3365 and the RCM3375 RabbitCore modules used with the additional BL2600
versions described in Section 1.2.2 support a removable memory card to store data and
Web pages. The RCM3365 and the RCM3375 both can handle up to a 128 MByte remov­able memory card, and the RCM3365 also has a 16 MByte onboard NAND flash.

NOTE: Rabbit-based systems do not implement the xD-Picture Card™ specification for

data storage, and are neither compatible nor compliant with xD-Picture Card™ card
readers.

The NAND flash and removable memory cards are particularly suitable for mass-storage
applications, but are generally unsuitable for direct program execution. The NAND flash
differs from parallel NOR flash (the type of flash memory used to store program code on
Rabbit-based boards and RabbitCore modules currently in production) in two respects.
First, the NAND flash requires error-correcting code (ECC) for reliability. Although
NAND flash manufacturers do guarantee that block 0 will be error-free, most manufactur­ers guarantee that a new NAND flash chip will be shipped with a relatively small percent­age of errors, and will not develop more than some maximum number or percentage of
errors over its rated lifetime of up to 100,000 writes. Second, the standard NAND flash
addressing method multiplexes commands, data, and addresses on the same I/O pins,
while requiring that certain control lines must be held stable for the duration of the NAND
flash access. The software function calls provided by Rabbit for the NAND flash take care
of the data-integrity and reliability attributes.

Figure 22 shows how to insert or remove the memory card. While you remove or insert
the memory card, take care to avoid touching the electrical contacts on the bottom of the
card to prevent electrostatic discharge damage to the card and to keep any moisture and
contaminants off the contacts. Do not remove or insert the memory card while it is being
accessed.

Figure 22. Insertion/Removal of Memory Card

User’s Manual 37

Rabbit recommends that you use header J6 on the RCM3365/RCM3375 only for the
memory card since other devices are not supported. Be careful to remove and insert the
memory card as shown, and be careful not to insert any foreign objects, which may short
out the contacts and lead to the destruction of your memory card.

Sample programs in the SAMPLES\BL2600\NANDFlash folder illustrate the use of the
NAND flash. These sample programs are described in Section 4.2.7, “Use of NAND
Flash.” Pay careful attention to the sample programs to see how to close files and secure
any data on the memory card before you remove it.

4. SOFTWARE

Dynamic C is an integrated development system for writing
embedded software. It runs on an IBM-compatible PC and is
designed for use with single-board computers and other devices
based on the Rabbit microprocessor.

Chapter 4 provides the libraries, function calls, and sample pro­grams related to the BL2600.

4.1 Running Dynamic C

You have a choice of doing your software development in the flash memory or in the static
RAM included on the BL2600. The flash memory and SRAM options are selected with
the Options > Project Options > Compiler menu.

The advantage of working in RAM is to save wear on the flash memory, which is limited
to about 100,000 write cycles. The disadvantage is that the code and data might not both
fit in RAM.

NOTE: On the BL2600, compiling a program to flash will produce a warning message.

You will receive an error message if you attempt to compile a program to the battery­backed data SRAM. If you still want to compile to the battery-backed data SRAM, you
will have to comment out some code as instructed in the error message. The program
should be run from the program execution SRAM after the programming cable is dis­connected. Your final code must always be stored in flash memory for reliable opera­tion. Select Code and BIOS in Flash, Run in RAM from the Dynamic C Options >
Project Options > Compiler menu to store the code in flash and copy it to the fast
program execution SRAM at run-time to take advantage of the faster clock speed. This
option optimizes the performance of the BL2600 with an RCM3200 RabbitCore module
running at 44.2 MHz.

NOTE: On the BL2610, an application can be developed in RAM, but cannot run stand-

alone from RAM after the programming cable is disconnected. Standalone applications
can only run from flash memory.

NOTE: Do not depend on the flash memory sector size or type. Due to the volatility of

the flash memory market, the BL2600 and Dynamic C were designed to accommodate
flash devices with various sector sizes.

User’s Manual 39

Developing software with Dynamic C is simple. Users can write, compile, and test C and
assembly code without leaving the Dynamic C development environment. Debugging
occurs while the application runs on the target. Alternatively, users can compile a program
to an image file for later loading. Dynamic C runs on PCs under Windows 95, 98, 2000,
NT, Me, and XP. Programs can be downloaded at baud rates of up to 460,800 bps after the
program compiles.

Dynamic C has a number of standard features:

• Full-feature source and/or assembly-level debugger, no in-circuit emulator required.

• Royalty-free TCP/IP stack with source code and most common protocols.

• Hundreds of functions in source-code libraries and sample programs:

 Exceptionally fast support for floating-point arithmetic and transcendental functions.

 RS-232 and RS-485 serial communication.

 Analog and digital I/O drivers.

2

 I

C, SPI, GPS, file system.

 LCD display and keypad drivers.

• Powerful language extensions for cooperative or preemptive multitasking

• Loader utility program to load binary images into Rabbit targets in the absence of

Dynamic C.

• Provision for customers to create their own source code libraries and augment on-line

help by creating “function description” block comments using a special format for
library functions.

• Standard debugging features:

 Breakpoints—Set breakpoints that can disable interrupts.

 Single-stepping—Step into or over functions at a source or machine code level, µC/OS-II aware.

 Code disassembly—The disassembly window displays addresses, opcodes, mnemonics, and

machine cycle times. Switch between debugging at machine-code level and source-code level by
simply opening or closing the disassembly window.

 Watch expressions—Watch expressions are compiled when defined, so complex expressions

including function calls may be placed into watch expressions. Watch expressions can be updated
with or without stopping program execution.

 Register window—All processor registers and flags are displayed. The contents of general registers

may be modified in the window by the user.

 Stack window—shows the contents of the top of the stack.

 Hex memory dump—displays the contents of memory at any address.

 STDIO window—

detected for debugging purposes.

printf outputs to this window and keyboard input on the host PC can be

printf output may also be sent to a serial port or file.

4.1.1 Upgrading Dynamic C

4.1.1.1 Patches and Updates

Dynamic C patches that focus on bug fixes and updates are available from time to time.
Check the Web site at www.rabbit.com/support/ for the latest patches, workarounds, and
updates.

The default installation of a patch or update is to install the file in a directory (folder)
different from that of the original Dynamic C installation. Rabbit recommends using a dif­ferent directory so that you can verify the operation of the patch or update without over­writing the existing Dynamic C installation. If you have made any changes to the BIOS or
to libraries, or if you have programs in the old directory (folder), make these same changes
to the BIOS or libraries in the new directory containing the patch. Do not simply copy
over an entire file since you may overwrite an update; of course, you may copy over any
programs you have written. Once you are sure the new patch or update works entirely to
your satisfaction, you may retire the existing installation, but keep it available to handle
legacy applications.

4.1.1.2 Upgrades

Dynamic C installations are designed for use with the board they are included with, and
are included at no charge as part of our low-cost kits. Dynamic C is a complete software
development system, but does not include all the Dynamic C features. Rabbit also offers
for sale add-on Dynamic C modules containing the popular µC/OS-II real-time operating
system, as well as PPP, Advanced Encryption Standard (AES), RabbitWeb, FAT File
System, Secure Socket Layer (SSL) and other select libraries. In addition to the Web­based technical support included at no extra charge, a one-year telephone-based technical
support module is also available for purchase.

User’s Manual 41

4.2 Sample Programs

Sample programs are provided in the Dynamic C Samples folder. The sample program

PONG.C demonstrates the output to the STDIO window.

The various directories in the Samples folder contain specific sample programs that illus­trate the use of the corresponding Dynamic C libraries.

The BL2600 folder provides sample programs specific to the BL2600. Each sample pro­gram has comments that describe the purpose and function of the program. Follow the
instructions at the beginning of the sample program.

To run a sample program, open it with the File menu (if it is not still open), then compile
and run it by pressing F9. The BL2600 must be in Program mode (see Section 3.7, “Serial
Programming Cable,”) and must be connected to a PC using the programming cable as
described in Section 2.2, “BL2600 Connections.”

More complete information on Dynamic C is provided in the Dynamic C User’s Manual.
TCP/IP specific functions are described in the Dynamic C TCP/IP User’s Manual. Infor­mation on using the TCP/IP features and sample programs is provided in Section 5,
“Using the TCP/IP Features.”

4.2.1 General BL2600 Sample Programs

The following sample programs are found in the SAMPLES\BL2600 folder.

• BOARD_ID.C—This program is used to identify the model of BL2600 being used, and

displays that information in the STDIO window.

4.2.2 Digital I/O

The following sample programs are found in the IO subdirectory in SAMPLES\BL2600.

• DIGIN.C—Demonstrates the use of the digital inputs. Using the Demonstration Board,

you can see an input channel toggle from HIGH to LOW when pressing a pushbutton
on the Demonstration Board. See Appendix C for hookup instructions for the Demon­stration Board. This sample program does not explicitly configure any of the configu­rable I/O, so all the configurable I/O are available by default as digital inputs.

• DIGIN_BANK.C—Demonstrates the use of digInBank to read digital inputs. Using the

Demonstration Board, you can see an input channel toggle from HIGH to LOW when
pressing a pushbutton on the Demonstration Board. See Appendix C for hookup
instructions for the Demonstration Board. This sample program does not explicitly con­figure any of the configurable I/O, so all the configurable I/O are available by default as
digital inputs.

• DIGOUT.C—Demonstrates the use of the configurable I/O sinking outputs. Using the

Demonstration Board, you can see an LED toggle on/off via a sinking output. See
Appendix C for hookup instructions for the Demonstration Board.

• DIGOUT_BANK.C—Demonstrates the use of digInBank to control the configurable I/O

sinking outputs. Using the Demonstration Board, you can see an LED toggle on/off via
a sinking output. See Appendix C for hookup instructions for the Demonstration Board.

42 SBC BL2600

• HIGH_CURRENT_IO.C—Demonstrates the use of the high-current outputs configured

as either sinking or sourcing outputs. High-current output HOUT0 is configured for
sourcing to provide power to the Demonstration Board. Outputs HOUT1 and HOUT2
are configured to demonstrate tristate operation to toggle the LEDs on the Demonstra­tion Board. Output HOUT3 is configured as a sinking output to toggle an LED on the
Demonstration Board. See Appendix C for hookup instructions for the Demonstration
Board.

• PWM.C—Demonstrates the use of the four PWM channels on Parallel Port F (PF4–PF7)

on pins DIN20–DIN23. The PWM signals are set for a frequency of 10 kHz with the
duty cycle adjustable from 1 to 99% by the user. Follow these instructions when run­ning this sample program.

1. Connect the jumper across pins 7–8 on header JP4 to select the GND option.

2. Once you have compiled and run this program, you may change duty cycle for a given PWM chan­nel via the Dynamic C
output. When monitoring with a voltmeter, you can compute the expected voltage

Vout = PWM percentage × 1.65 V

since the output voltage swing is from 0 V to 1.65 V DC.

STDIO window and use either an oscilloscope or a voltmeter to view the

4.2.3 Serial Communication

The following sample programs are found in the RS232 subdirectory in SAMPLES\BL2600.

• PARITY.C—This sample program repeatedly sends byte values 0–127 from Serial Port F

to Serial Port C. The program switches between generating parity and not generating
parity on Serial Port F. Serial Port C will always be checking parity, so parity errors
should occur during every other sequence. The results are displayed in the Dynamic C

STDIO window.

Connect TxF to RxC before compiling and running this sample program.

NOTE: For the sequence that does yield parity errors, the errors won't occur for each

byte received. This is because certain byte patterns along with the stop bit will appear to
generate the correct parity for the UART.

• SIMPLE3WIRE.C—This program demonstrates basic RS-232 serial communication.

Connect TxC to RxF on header J17 and connect TxF to RxC on header J17 before com­piling and running this sample program.

• SIMPLE5WIRE.C—This program demonstrates 5-wire RS-232 serial communication.

Connect TxC to RxC on header J17 and connect TxF to RxF on header J17 before com­piling and running this sample program.

TxF and RxF become the flow control RTS and CTS. To test flow control, disconnect
RTS from CTS while running this program. Characters should stop printing in the
Dynamic C STDIO window and should resume when RTS and CTS are connected again

User’s Manual 43

The following sample programs are found in the RS485 subdirectory in SAMPLES\BL2600.

• MASTER.C—This program demonstrates a simple RS-485 transmission of lower case

letters to a slave. The slave will send back converted upper case letters back to the
master BL2600 and display them in the STDIO window. Use SLAVE.C to program the
slave. Make the following connections between the master and slave:

485+ to 485+
485- to 485­GND to GND

NAND flash chip to the Dynamic C STDIO window, and the contents may be redi­rected to a serial port.

When the sample program starts running, it attempts to initialize the user-selected
NAND flash chip. If the initialization is successful and the main page size is accept­able, the nonerased page contents (non 0xFF) from the NAND flash page are dumped
to the Dynamic C STDIO win.for inspection.

Note that an error message will appear when the first 32 pages (0x20 pages) are
“dumped.” You may ignore the error message.

• NFLASH_INSPECT.C—This program is a utility for inspecting the contents of a

NAND flash chip. When the sample program starts running, it attempts to initialize the
NAND flash chip selected by the user. Once a NAND flash chip is found, the user can
execute various commands to print out the contents of a specified page, clear (set to
zero) all the bytes in a specified page, erase, or write to specified pages.

CAUTION: When you run this sample program, enabling the #define NFLASH_-

CANERASEBADBLOCKS macro makes it possible to write to bad blocks. The first two

blocks on the memory card are marked bad to protect the configuration data needed to
use the card in a digital camera or PC. You will only be able to use the memory card in
Rabbit-based systems if either of the first two blocks is written to.

• NFLASH_LOG.C—This program runs a simple Web server and stores a log of hits in

the NAND flash. This log can be viewed and cleared from a browser.

46 SBC BL2600

• NFLASH_ERASE.C—This program is a utility to erase all the good blocks on a NAND

flash chip. When the program starts running, it attempts to initialize the NAND flash
chip selected by the user. If the initialization is successful, the progress in erasing the
blocks is displayed in the Dynamic C STDIO window.

4.2.8 Real-Time Clock

If you plan to use the real-time clock functionality in your application, you will need to set
the real-time clock. You may set the real-time clock using the SETRTCKB.C sample pro­gram from the Dynamic C SAMPLES\RTCLOCK folder. The RTC_TEST.C sample pro­gram in the Dynamic C SAMPLES\RTCLOCK folder provides additional examples of how

4.4.3 Serial Communication

Library files included with Dynamic C provide a full range of serial communications sup­port. The RS232.LIB library provides a set of circular-buffer-based serial functions. The

PACKET.LIB library provides packet-based serial functions where packets can be delim-

ited by the 9th bit, by transmission gaps, or with user-defined special characters. Both
libraries provide blocking functions, which do not return until they are finished transmit­ting or receiving, and nonblocking functions, which must be called repeatedly until they
are finished. For more information, see the Dynamic C User’s Manual and Technical Note
213, Rabbit Serial Port Software.

Use the following function calls with the BL2600.

int serMode(int mode);

User interface to set up BL2600 serial communication lines. Call this function after serXOpen().

Whether you are opening one or multiple serial ports, this function must be executed after executing the
last serXOpen function AND before you start using any of the serial ports. This function is non-reentrant.

If Mode 1 is selected, CTS/RTS flow control is exercised using the serCflowcontrolOn and
serCflowcontrolOff functions from the RS232.LIB library.

PARAMETER

mode is the defined serial port configuration.

Mode

0 RS-232, 3-wire RS-232, 3-wire RS-232, 3-wire

called before accessing the A/D converter chip.

NOTE: If you plan to configure the D/A converter chip using anaOutConfig, you must

anaOutConfig before executing anaInConfig. This is because the A/D con-

call

4.4.5 D/A Converter Outputs

int anaOutConfig(char configuration, int mode);

Configures the D/A converter chip for a given output voltage range, 0–10 V or ±10 V, and loads the cali­bration data for use by the D/A converter API functions. This function must be called before accessing
any of the D/A converter channels.

NOTE: If you are using the analog outputs, you must configure the D/A converter chip

using the
A/D converter chip. This is because the A/D converter chip uses internal channels 4–7
on the D/A converter chip to bias the A/D converter input circuit, and the correct con­figuration of the A/D converter would be affected if the D/A converter configuration
was changed later.

PARAMETERS

configuration sets the output configuration as follows:

0 = unipolar operation. (0–10V and 4–20 mA)
1 = bipolar operation. (±10V and 4–20 mA)

NOTE: When the D/A converter is configured for bipolar operation, the 4–20 mA chan-

nels change from 12-bit to 11-bit resolution.

mode is the mode of operation:

anaOutConfig function before executing anaInConfig to configure the

0 = asynchronous—an output is updated at the time data are written to the given channel

4.4.6 SRAM Use

The BL2600 model and some memory variations described in Section 1.2.2 have a battery­backed data SRAM and a program-execution SRAM. Dynamic C provides the

tected

keyword to identify variables that are to be placed into the battery-backed

pro-

SRAM. The compiler generates code that maintains two copies of each protected variable
in the battery-backed SRAM. The compiler also generates a flag to indicate which copy of
the protected variable is valid at the current time. This flag is also stored in the battery­backed SRAM. When a protected variable is updated, the “inactive” copy is modified, and
is made “active” only when the update is 100% complete. This assures the integrity of the
data in case a reset or a power failure occurs during the update process. At power-on the
application program uses the active copy of the variable pointed to by its associated flag.

The sample code below shows how a protected variable is defined and how its value can
be restored.

protected nf_device nandFlash;

int main() {
...

_sysIsSoftReset(); // restore any protected variables

The

bbram

keyword may also be used instead if there is a need to store a variable in bat­tery-backed SRAM without affecting the performance of the application program. Data
integrity is not assured when a reset or power failure occurs during the update process.

Additional information on

bbram

and

protected

variables is available in the Dynamic C

User’s Manual.

4.4.7 NAND Flash Drivers

The Dynamic C

NANDFlash\NFLASH.LIB

library is used to interface to NAND flash
memory devices on the RCM3365 and the RCM3375. The function calls were written spe­cifically to work with industry-standard flash devices with a 528-byte page program and
16896-byte block erase size. The NAND flash function calls are designed to be closely
cross-compatible with the newer serial flash function calls found in the
library. These function calls use an

nf_device

structure as a handle for a specific NAND

SFLASH.LIB

flash device. This allows multiple NAND flash devices to be used by an application.

More information on these function calls is available in the Dynamic C Function Refer-
ence Manual.

Chapter 5 discusses using the TCP/IP features on the BL2600
and BL2610 boards. The TCP/IP feature is not available on
BL2610.

5.1 TCP/IP Connections

Before proceeding you will need to have the following items.

• If you don’t have Ethernet access, you will need at least a 10Base-T Ethernet card

(available from your favorite computer supplier) installed in a PC.

• Two RJ-45 straight-through CAT 5/6 Ethernet cables and a hub, or an RJ-45 crossover

CAT 5/6 Ethernet cable.

The CAT 5/6 Ethernet cables and Ethernet hub are available from Rabbit in a TCP/IP tool
kit. More information is available at www.rabbit.com.

1. Connect the AC adapter and the programming cable as shown in Chapter 2, “Getting
Started.”

2. Ethernet Connections

If you do not have access to an Ethernet network, use a crossover CAT 5/6 Ethernet cable
to connect the BL2600 to a PC that at least has a 10Base-T Ethernet card.

If you have Ethernet access, use a straight-through CAT 5/6 Ethernet cable to establish an
Ethernet connection to the BL2600 from an Ethernet hub. These connections are shown in
Figure 23.

User’s Manual 71

Figure 23. Ethernet Connections

The PC running Dynamic C through the serial programming port on the BL2600 does not
need to be the PC with the Ethernet card.

3. Apply Power

Plug in the AC adapter. The BL2600 is now ready to be used.

NOTE: A hardware RESET is accomplished by unplugging the AC adapter, then plug-

ging it back in, or by momentarily grounding the board reset input at pin 9 on screw ter­minal header J2.

When working with the BL2600, the green LNK light is on when a program is running and
the board is properly connected either to an Ethernet hub or to an active Ethernet card. The
orange ACT light flashes each time a packet is received.

72 SBC BL2600

5.2 TCP/IP Sample Programs

We have provided a number of sample programs demonstrating various uses of TCP/IP for
networking embedded systems. These programs require that you connect your PC and the
BL2600 together on the same network. This network can be a local private network (pre­ferred for initial experimentation and debugging), or a connection via the Internet.

5.2.1 How to Set IP Addresses in the Sample Programs

With the introduction of Dynamic C 7.30 we have taken steps to make it easier to run
many of our sample programs. You will see a TCPCONFIG macro. This macro tells
Dynamic C to select your configuration from a list of default configurations. You will
have three choices when you encounter a sample program with the TCPCONFIG macro.

1. You can replace the TCPCONFIG macro with individual MY_IP_ADDRESS, MY_NET-

MASK

, MY_GATEWAY, and MY_NAMESERVER macros in each program.

2. You can leave TCPCONFIG at the usual default of 1, which will set the IP configurations
to 10.10.6.100, the netmask to 255.255.255.0, and the nameserver and gateway
to 10.10.6.1. If you would like to change the default values, for example, to use an IP
address of 10.1.1.2 for the BL2600 board, and 10.1.1.1 for your PC, you can edit
the values in the section that directly follows the “General Configuration” comment in
the TCP_CONFIG.LIB library. You will find this library in the LIB\TCPIP directory.

3. You can create a CUSTOM_CONFIG.LIB library and use a TCPCONFIG value greater
than 100. Instructions for doing this are at the beginning of the TCP_CONFIG.LIB
library in the LIB\TCPIP directory.

There are some other “standard” configurations for TCPCONFIG that let you select differ­ent features such as DHCP. Their values are documented at the top of the TCP_CON-

FIG.LIB

library in the LIB\TCPIP directory. More information is available in the

Dynamic C TCP/IP User’s Manual.

Direct Connection PC to BL2600

Board

When your computer is connected directly to the BL2600 via an Ethernet connection, you
need to assign an IP address to your computer. To assign the PC the address

10.10.6.101 with the subnetmask 255.255.255.0, do the following.

Click on Start > Settings > Control Panel to bring up the Control Panel, and then
double-click the Network icon. Depending on which version of Windows you are using,
look for the TCP/IP Protocol/Network > Dial-Up Connections/Network line or tab.
Double-click on this line or select Properties or Local Area Connections > Properties
to bring up the TCP/IP properties dialog box. You can edit the IP address and the subnet
mask directly. (Disable “obtain an IP address automatically”.) You may want to write
down the existing values in case you have to restore them later. It is not necessary to edit
the gateway address since the gateway is not used with direct connect.

74 SBC BL2600

5.2.3 Run the PINGME.C Demo

Connect the crossover cable from your computer’s Ethernet port to the BL2600’s RJ-45
Ethernet connector. Open this sample program from the SAMPLES\TCPIP\ICMP folder,
compile the program, and start it running under Dynamic C. When the program starts run­ning, the green LNK light on the BL2600 should be on to indicate an Ethernet connection
is made. (Note: If the LNK light does not light, you may not have a crossover cable, or if
you are using a hub perhaps the power is off on the hub.)

The next step is to ping the board from your PC. This can be done by bringing up the MS­DOS window and running the ping program:

ping 10.10.6.100

or by Start > Run

and typing the command

ping 10.10.6.100

Notice that the orange ACT light flashes on the BL2600 while the ping is taking place, and
indicates the transfer of data. The ping routine will ping the board four times and write a
summary message on the screen describing the operation.

5.2.4 Running More Demo Programs With a Direct Connection

The program SSI.C (SAMPLES\BL2600\TCPIP\) demonstrates how to make the
BL2600 a Web server. This program allows you to turn the LEDs on an attached Demon­stration Board from the Tool Kit on and off from a remote Web browser. The LEDs on the
Demonstration Board match the ones on the Web page. Follow the instructions included
with the sample program. As long as you have not modified the TCPCONFIG 1 macro in
the sample program, enter the following server address in your Web browser to bring up
the Web page served by the sample program.

http://10.10.6.100.

Otherwise use the TCP/IP settings you entered in the TCP_CONFIG.LIB library.

The sample program SMTP.C (SAMPLES\BL2600\TCPIP\) allows you to send an E-mail
when a switch on the Demonstration Board is pressed. Follow the instructions included
with the sample program.

The sample program TELNET.C (SAMPLES\BL2600\TCPIP\) allows you to communi­cate with the BL2600 using the Telnet protocol. This program takes anything that comes
in on a port and sends it out Serial Port C. It uses a digital input to indicate that the TCP/IP
connection should be closed and a digital output to toggle a LED to indicate that there is
an active connection.

Follow the instructions included with the sample program. Run the Telnet program on
your PC (Start > Run telnet 10.10.6.100). As long as you have not modified the

TCPCONFIG 1 macro in the sample program, the IP address is 10.10.6.100 as shown;

otherwise use the TCP/IP settings you entered in the TCP_CONFIG.LIB library. Each
character you type will be printed in Dynamic C's STDIO window, indicating that the
board is receiving the characters typed via TCP/IP.

5.3 Where Do I Go From Here?

NOTE: If you purchased your BL2600 through a distributor or Rabbit partner, contact

the distributor or partner first for technical support.

If there are any problems at this point:

• Use the Dynamic C Help menu to get further assistance with Dynamic C.

• Check the Rabbit Technical Bulletin Board and forums at www.rabbit.com/support/bb/

and at www.rabbit.com/forums/.

• Use the Technical Support e-mail form at www.rabbit.com/support/questionSubmit.shtml.

If the sample programs ran fine, you are now ready to go on.

Additional sample programs are described in the Dynamic C TCP/IP User’s Manual.

Refer to the Dynamic C TCP/IP User’s Manual to develop your own applications. An
Introduction to TCP/IP provides background information on TCP/IP, and is available on
the Web si te.

A.1.1 Exclusion Zone

It is recommended that you allow for an “exclusion zone” of 0.25" (6 mm) around the
BL2600 in all directions when the BL2600 is incorporated into an assembly that includes
other components. This “exclusion zone” that you keep free of other components and
boards will allow for sufficient air flow, and will help to minimize any electrical or EMI
interference between adjacent boards. An “exclusion zone” of 0.12" (3 mm) is recom­mended below the BL2600. Figure A-2 shows this “exclusion zone.”

The areas around the crystal oscillator and the battery backup circuit on the BL2600 mod­ule have had the Dow Corning silicone-based 1-2620 conformal coating applied. The con­formally coated areas are shown in Figure A-4. The conformal coating protects these
high-impedance circuits from the effects of moisture and contaminants over time.

Figure A-4. BL2600 Areas Receiving Conformal Coating

Any components in the conformally coated area may be replaced using standard soldering
procedures for surface-mounted components. A new conformal coating should then be
applied to offer continuing protection against the effects of moisture and contaminants.

The PD0, PD1, PE0, and PE2 signals are configured on the RabbitCore module, and not on
the BL2600. These parallel-port bits are configured for Ethernet on RabbitCore modules
with Ethernet and for output low on RabbitCore modules without Ethernet. The signals are
not available on the BL2600 for customer use in applications.

SUPPLIES

Appendix B describes the power circuitry provided on the
BL2600.

B.1 Power Supplies

Power is supplied to the BL2600 via the friction-lock connector at J12. The BL2600 is
protected against reverse polarity by a diode at D1 as shown in Figure B-1.

Figure B-1. BL2600 Power Supply

The input voltage range is from 9 V to 36 V. A switching power regulator is used to pro­vide +5 V for the BL2600 logic circuits. In turn, the regulated +5 V DC power supply is
used to drive a regulated +3.3 V power supply and ±12 V power supplies used by the op­amps driving the digital outputs.

The digital ground and the analog ground share a single split ground plane on the board,
with the analog ground connected at a single point to the digital ground by a 0  resistor
(R57). This is done to minimize digital noise in the analog circuits and to eliminate the
possibility of ground loops. External connections to analog ground are made on a polar­ized friction-lock connector at J8.

User’s Manual 87

B.1.1 Power for Analog Circuits

950 mA·h

12 µA

------------------------

9.0 years.=

Power to the analog circuits is provided by way of a one-stage low-pass filter, which
isolates the analog section from digital noise generated by the other components. The ana­log +5 V supply powers the D/A converter, and is not accessible to the user. The A/D con­verter is powered by the regulated +3.3 V supply, and supplies the +2.048 V reference
violate from which the 1.667 V and 2.5 V reference voltages for the D/A converter output
circuits are derived.

B.2 Batteries and External Battery Connections

The SRAM and the real-time clock on the BL2600 module have battery backup. Power to
the SRAM and the real-time clock (VRAM) is provided by two different sources, depending
on whether the main part of the BL2600 is powered or not. When the BL2600 is powered
normally, and the +3.3 V supply is within operating limits, the SRAM and the real-time
clock are powered from the +3.3 V supply. If power to the board is lost or falls below 2.93 V
(2.63 V on the BL2610), the VRAM and real-time clock power will come from the battery.
The reset generator circuit controls the source of power by way of its /RESET output signal.

A replaceable 950 mA·h lithium battery provides power to the real-time clock and SRAM
when external power is removed from the circuit board. The drain on the battery is typically
less than 10 µA when there is no external power applied to the BL2600, and so the expected
shelf life of the battery is

B.2.1 Replacing the Backup Battery

The battery is user-replaceable, and is fitted in a battery holder. To replace the battery, lift
up on the spring clip and slide out the old battery. Use only a Panasonic CR2477 or equiv­alent replacement battery, and insert it into the battery holder with the + side facing up.

NOTE: The SRAM contents and the real-time clock settings will be lost if the battery is

replaced with no power applied to the BL2600. Exercise care if you replace the battery
while external power is applied to the BL2600.

CAUTION: There is an explosion danger if the battery is short-circuited, recharged,
or replaced incorrectly. Replace the battery only with the same type or an equivalent
type recommended by the battery manufacturer. Dispose of used batteries according
to the battery manufacturer’s instructions.

Cycle the main power off/on on the BL2600 whenever you replace the backup battery.
This step will minimize the current drawn by the real-time clock oscillator circuit from the
backup battery should the BL2600 experience a loss of main power.

NOTE: Remember to cycle the main power off/on any time the BL2600’s RabbitCore

module is removed from the main board since removing the RabbitCore module
disconnects power to its real-time clock oscillator.
