1.5 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 Rabbit-based
systems at frequencies above 300 MHz are generally well below background noise levels.
The BL2100 single-board computer has been tested and was found to
be in conformity with the following applicable immunity and emission
standards. The BL2110, BL2120, and BL2130 single-board computers
are also CE qualified as they are sub-versions of the BL2100 singleboard computer. Boards that are CE-compliant have the CE mark.
Immunity
The BL2100 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 BL2100 series of single-board computers meets the following emission standards with
the Rabbit 2000 spectrum spreader turned on and set to the normal mode. The spectrum
spreader is only available with Rev. C or higher of the Rabbit 2000 microprocessor. This
microprocessor is used in all BL2100 series boards that carry the CE mark.
• EN55022:1998 Class A
• FCC Part 15 Class A
NOTE: The BL2100 satisfied the Class A limits but not the Class B limits. Such equip-
ment need not be restricted in its sale, but the following warning must be included in
the instructions for its use.
Warning
This is a Class A product. In a domestic environment this product may cause radio
interference, in which case the user may be required to take adequate measures.
Additional shielding or filtering may be needed to meet Class B emissions standards.

1.5.1 Design Guidelines
Note the following requirements for incorporating a BL2100 series single-board computer
into your application to comply with CE requirements.
General
• The power supply provided with the T ool 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 BL2100 single-board computer to outdoor cables, the customer is
responsible for providing CE-approved surge/lighting 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 BL2100, it is the responsibility of the end-user to use
proper ESD precautions to prevent ESD damage to the BL2100.
Safety
• All inputs and outputs to and from the BL2100 single-board computer must not be con-
nected to voltages exceeding SELV levels (42.4 V AC peak, or 60 V DC).
• The lithium backup battery circuit on the BL2100 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.
1.5.2 Interfacing the BL2100 to Other Devices
There are two versions of the LCD/keypad module that may be used with the BL2100: a
plug-in version (Part No. 101-0465), and a remote panel-mounted version with bezel (Part
No. 101-0502). The BL2100 with the LCD/keypad module plugged in may be regarded as
a “maintenance unit” that conforms to the same CE standards as does the BL2100 alone,
where the entire assembly is mounted inside an enclosure, and the enclosure is only
opened to “tune up” the system. In addition, the cable for a panel-mounted LCD/keypad
module should be less than 30 cm (12") to maintain CE compliance. Appendix C provides
complete information for mounting and using the LCD/keypad module.
Since the BL2100 single-board computers are 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.rabbit.com.

BL2100 Main Board
Chapter 2 explains how to connect the programming cable and
power supply to the BL2100.
2.1 BL2100 Connections
1. Remove the RabbitCore module from the BL2100 main board, and set the module
aside. The module is removed to allow access to the mounting holes on the main
BL2100 board, and will be plugged back in to the main board later.
NOTE: If you are working with more than one BL2100 at a time, take care to keep the
BL2100 main boards and their corresponding RabbitCore modules paired since the RabbitCore modules store calibration constants specific to the BL2100 main board to which they
are plugged in.

headers, and do not bend them as you press down to mate the module with the BL2100
main board.
NOTE: If you are working with more than one BL2100 at a time, take care to keep the
BL2100 main boards and their corresponding RabbitCore modules paired since the RabbitCore modules store calibration constants specific to the BL2100 main board to which they
are plugged in.

shrink wrap
and debug the BL2100.
Connect the 10-pin PROG connector of the programming cable to header J1 on the BL2100
RabbitCore module. Ensure that the colored edge lines up with pin 1 as shown. (Do not use
DIAG connector, which is used for a nonprogramming serial connection.) Connect the
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.
Figure 5. Programming Cable Connections
NOTE: Never disconnect the programming cable by pulling on the ribbon cable. Carefully
pull on the connector to remove it from the header.
NOTE: Some PCs now come equipped only with a USB port. It may be possible to use an
12 Smartcat (BL2100)
RS-232/USB converter with the programming cable supplied with the Tool Kit. An RS232/USB converter (part number 20-151-0178) is available through the Web store. Note that
not all RS-232/USB converters work with Dynamic C.
5. Connect the power supply.
First, prepare the AC adapter for the country where it will be used by selecting the plug.
The BL2100 Tool Kit presently includes Canada/Japan/U.S., Australia/N.Z., U.K., and
European style plugs. Snap in the top of the plug assembly into the slot at the top of the
AC adapter as shown in Figure 5, then press down on the spring-loaded clip below the
plug assembly to allow the plug assembly to click into place.
Connect the bare ends of the power supply to the +RAW and GND positions on screwterminal header J5 (IDC header J4) as shown in Figure 6.
Figure 6. Power Supply Connections
6. Apply power.
Plug in the AC adapter. If you are using your own power supply, it must provide 9 to
36 V DC (13 to 36 V DC if you intend to use the full range of the D/A converter
outputs)—voltages outside this range could damage the BL2100.
CAUTION: Unplug the power supply while you make or otherwise work with the connections
to the headers. This will protect your BL2100 from inadvertent shorts or power spikes.
NOTE: A hardware RESET is done by unplugging the AC adapter, then plugging it back in.
User’s Manual 13
2.2 Installing Dynamic C
If you have not yet installed Dynamic C version 7.06 (or a later version), do so now by
inserting the Dynamic C CD 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 installation program will guide you through the installation process. Most steps of the
process are self-explanatory.
Dynamic C uses a COM (serial) port to communicate with the target development system.
The installation allows you to choose the COM port that will be used. The default selection is COM1. You may select any available port for Dynamic C’s use. If you are not certain which port is available, select COM1. This selection can be changed later within
Dynamic C.
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 precompiled software to a target system.
If you have purchased the optional Dynamic C Rabbit Embedded Security Pack, install it
after installing Dynamic C. You must install the Rabbit Embedded Security Pack in the
same directory where Dynamic C was installed.
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 installation
of the later version will be in a different folder, and a separate icon will appear on your desktop.
14 Smartcat (BL2100)
2.3 Starting Dynamic C
Once the BL2100 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 BL2100, choose Options >
Project Options
and select “Use USB to Serial Converter” under the Communications
tab. Click OK.
2.4 Run a Sample Program
Use the File menu to open the sample program PONG.C, which is in the Dynamic C
SAMPLES folder. Press function key F9 to compile and run the program. The STDIO
window will open on your PC 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.
2.4.1 Troubleshooting
If Dynamic C cannot find the target system (error message "No Rabbit Processor
Detected."
• Check that the BL2100 is powered correctly — the AC adapter should be plugged in to the
+RAW and GND positions on screw-terminal header J5 (IDC header J4).
):
• Check both ends of the programming cable to ensure that they are firmly plugged into
the PC and the PROG connector, not the DIAG connector, is plugged in to the programming port on the RabbitCore module with the marked (colored) edge of the programming cable towards pin 1 of the programming header.
• Ensure that the RabbitCore module is firmly and correctly installed in its connectors on
the BL2100 main board.
• Dynamic C uses the COM port specified during installation. Select a different COM
port within Dynamic C. From the
Communications. Select another COM port from the list, then click OK. Press
<Ctrl-Y> to force Dynamic C to recompile the BIOS. If Dynamic C still reports it is
Options menu, select Project Options, then select
unable to locate the target system, repeat the above steps until you locate the COM port
used by the programming cable.
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.
User’s Manual 15
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.
2.5 Where Do I Go From Here?
If the sample program ran fine, you are now ready to go on to other sample programs and to
develop your own applications. The source code for the sample programs
you to modify them for your own use. The BL2100 User’s Manual also provides complete
hardware reference information and describes the software function calls for the BL2100 and
the optional LCD/keypad module.
For advanced development topics, refer to the Dynamic C User’s Manual and the
Dynamic C TCP/IP User’s Manual, also in the online documentation set.
2.5.1 Technical Support
NOTE: If you purchased your BL2100 through a distributor or Rabbit partner, contact the
distributor or partner first for technical support.
If there are any problems at this point:
is provided to allow
• 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/.
If the sample program ran fine, you are now ready to go on to explore other BL2100 features and develop your own applications.
Chapter 3, “Subsystems,” provides a description of the BL2100’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.

Standard BL2100 models are equipped with two 1 × 12 screw-terminal strips (J8 and J14),
and two 1 × 14 screw-terminal strips (J5 and J11). The BL2100 and BL2110 also have the
RJ-45 Ethernet jack and one 1 × 16 screw-terminal strip (J2).
There is provision on the circuit board to accommodate one of the following types of
connectors instead of the screw-terminal strips.
• 2 × 17, 2 × 20, and 2 × 25 IDC headers with a pitch of 0.1".
• 1 × 17, 1 × 20, and 1 × 25 friction-lock connectors with a pitch of 0.1". The holes used
by the friction-lock connectors are on the “outside” edges of the connector locations.
• 1 × 17, 1 × 20, and 1 × 25 bottom-mount sockets with a pitch of 0.1". The holes for the
bottom-mount sockets are on the “outside” edges of the connector locations
The pinouts for these connectors are shown in Figure 8(b).

3.2.1 Digital Inputs
The BL2100 has 24 digital inputs, IN00–IN23, 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 +K2 or down to 0 V in banks of eight by changing a surface-mounted
0 resistor as shown in Figure 9.
Figure 9. BL2100 Digital Inputs [Pulled Up—Factory Default]
NOTE: If the inputs are pulled up to +K2, the voltage range over which the digital inputs
are protected changes to K2 – 36 V to +36 V.
The actual switching threshold is approximately 2.40 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.

SINKING OUTPUT
SOURCING OUTPUT
The BL2100 has 16 digital outputs, OUT00–OUT15, which can each sink or source up to
200 mA. Figure 11 shows a wiring diagram for using the digital outputs in a sinking or a
souring configuration.
All the digital outputs sink and source actively. They can be used as high-side drivers,
low-side drivers, or as an H-bridge driver. When the BL2100 is first powered up or reset,
all the outputs are disabled, that is, at a high-impedance status, until the digoutConfig
software function call is made. The digoutConfig call sets the initial state of each digital output according to the configuration specified by the user, and enables the digital outputs to their initial status.
OUT00–OUT07 are powered by to +K1, and OUT08–OUT15 are powered by +K2.
K1 and K2 can each be up to 36 V. They don't have to be same.
All the sinking current, which could be up to 3.2 A, is returned through the GND pins. Be
sure to use a suitably sized GND and keep the distance to the power supply as short as
possible. Since there are two GND terminals (header J5/J4, and header J11/J10), it is

For the H bridge, which is shown in Figure 12,
K1 and K2 should be the same if two digital outputs used for the H bridge are on different banks.

3.3 Serial Communication
The BL2100 has two RS-232 serial ports, which can be configured as one RS-232 serial
channel (with R TS/CTS) or as two RS-232 (3-wire) channels using the serMode software
function call. Table 2 summarizes the options.
Table 2. Serial Communication Configurations
Serial Port
Mode
B C D
0 RS-232, 3-wire RS-232, 3-wire RS-485
1 RS-232, 5-wire CTS/R TS RS-485
The BL2100 also has one RS-485 serial channel and 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 BL2100
boards typically use all four ports in the asynchronous serial mode. Serial Ports B and C
are used for RS-232 communication, and Serial Port D is used for RS-485 communication. The BL2100 uses an 11.0592 MHz crystal, which is doubled to 22.1 184 MHz. At this
frequency, the BL2100 supports standard asynchronous baud rates up to a maximum of
230,400 bps.
3.3.1 RS-232
The BL2100 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
2000’ s CMOS/TTL signals to RS-232 signal levels. Note that the polarity is reversed in an
RS-232 circuit so that a +5 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 BL2100’s maximum baud rate for distances of up to
15 m.
3.3.2 RS-485
The BL2100 has one RS-485 serial channel, which is connected to the Rabbit 2000 Serial
Port D through an RS-485 transceiver. The half-duplex communication uses the Rabbit
2000’s PB6 pin to control the transmit enable on the communication line.

Figure 14. 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 BL2100 units in the network by removing both jumpers from
header JP1.
TIP: Save the jumpers for possible future use by “parking” them across pins 1–3 and 4–6
of header JP1. Pins 3 and 4 are not otherwise connected to the BL2100.

Figure 15 shows the pinout for the Ethernet port (J2 on the BL2100 module). Note that
there are two standards for numbering the pins on this connector—the convention used
here, and numbering in reverse to that shown. Regardless of the numbering convention
followed, the pin positions relative to the spring tab position (located at the bottom of the
RJ-45 jack in Figure 15) are always absolute, and the RJ-45 connector will work properly
with off-the-shelf Ethernet cables.
Figure 15. RJ-45 Ethernet Port Pinout
RJ-45 pinouts are sometimes numbered opposite to the way shown in Figure 15.
Two LEDs are placed next to the RJ-45 Ethernet jack, one to indicate an Ethernet link
(LNK) and one to indicate Ethernet activity (ACT).
The transformer/connector assembly ground is connected to the BL2100 module printed
circuit board digital ground via a 0 resistor “jumper,” R29, as shown in Figure 16.
Figure 16. Isolation Resistor R29
The factory default is for the 0 resistor “jumper” at R29 to be installed. In high-noise
environments, remove R29 and ground the transformer/connector assembly directly
through the chassis ground. This will be especially helpful to minimize ESD and/or EMI
problems.

3.3.4 Programming Port
The RabbitCore module on the BL2100 has a 10-pin programming header. The programming port uses the Rabbit 2000’s Serial Port A for communication. Dynamic C uses the
programming port to download and debug programs.
The programming port is also used for the following operations.
• Cold-boot the Rabbit 2000 on the RabbitCore module after a reset.
• Remotely download and debug a program over an Ethernet connection using the
RabbitLink EG2110.
• Fast copy designated portions of flash memory from one Rabbit-based board (the
master) to another (the slave) using the Rabbit Cloning Board.
In addition to Serial Port A, the Rabbit 2000 startup-mode (SMODE0, SMODE1), status,
and reset pins are available on the serial programming port.
The two startup mode pins determine what happens after a reset—the Rabbit 2000 is
either cold-booted or the program begins executing at address 0x0000.
The status pin is used by Dynamic C to determine whether a Rabbit microprocessor is
present. The status output has three different programmable functions:
1. It can be driven low on the first op code fetch cycle.
2. It can be driven low during an interrupt acknowledge cycle.
3. It can also serve as a general-purpose output.
The /RESET_IN pin is an external input that is used to reset the Rabbit 2000 and the
onboard peripheral circuits on the RabbitCore module. The serial programming port can be
used to force a hard reset on the RabbitCore module by asserting the /RESET_IN signal.
Alternate Uses of the Serial Programming Port
All three clocked Serial Port A signals are available as
• a synchronous serial port
• an asynchronous serial port, with the clock line usable as a general CMOS input
The programming port may also be used as a serial port once the application is running.
The SMODE pins may then be used as inputs and the status pin may be used as an output.
Refer to the Rabbit 2000 Microprocessor User’s Manual for more information.

The programming cable is used to connect the programming port of the RabbitCore module
to a PC serial COM port. The programming cable converts the RS-232 voltage levels used
by the PC serial port to the TTL voltage levels used by the Rabbit 2000.
When the PROG connector on the programming cable is connected to the RabbitCore
module’s programming header, programs can be downloaded and debugged over the serial
interface.
The DIAG connector of the programming cable may be used on the programming header of
the RabbitCore module with the module operating in the Run Mode. This allows the programming port to be used as a regular serial port.
3.4.1 Changing Between Program Mode and Run Mode
The BL2100 is automatically in Program Mode when the PROG connector on the programming cable is attached to the RabbitCore module, and is automatically in Run Mode
when no programming cable is attached. When the Rabbit 2000 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 2000 in
the Program Mode. When the programming cable’s PROG connector is not attached, the
SMODE pins are pulled low, causing the Rabbit 2000 to operate in the Run Mode.
A program “runs” in either mode, but can only be downloaded and debugged when the
BL2100 is in the Program Mode.
Refer to the Rabbit 2000 Microprocessor User’s Manual for more information on the programming port and the programming cable.

and three are used internally for the reference voltages: 4.096 V (V
and Analog Ground. These internal voltages can be used to check the functioning of the
A/D converter chip.
The A/D converter chip only measures voltages between 0 V and the applied reference
voltage. Therefore, each external input has circuitry that provides scaling and buffering.
All 11 external inputs are scaled and buffered to provide the user with an input impedance
of 1 M and a range of -10.24 V to +10.24 V.

The op-amp is powered from the +V supply. The 1 M and 200 k resistors set the gain
(scale factor), which is 0.2 in this case. This results in a dynamic input range of 0.2 × 20.48 V
or 4.096 V. The center point of this range is set by the 1.707 V reference voltage. With the
reference set to 1.707 V, the center point is at 0 V and the input voltage can range from
-10.24 V to +10.24 V. To maintain the best accuracy, the input range should be limited to
-10.0 V to +10.0 V.
The A/D converter inputs are factory-calibrated and the calibration constants are stored in
flash memory . You may calibrate the A/D converter inputs at a later time using the software
functions described in Section 4.4.4, “A/D Converter Inputs.” The

This circuit generates the 4.096 V reference voltage, which is used by the A/D converter
and by the D/A converters. This sets the operating range of the A/D converter and the D/A
converters (0–10 V). To use the full accuracy of the A/D converter and the D/A converters, this voltage must be accurate to the same degree.
The reference zener diode in combination with the 300 resistor form a shunt regulator.
The 4.096 V reference voltage then feeds the A/D converter, the D/A converters, and the
voltage divider composed of the 10 k and the 14 k resistors. The voltage divider generates a second reference voltage of 1.707 V to feed the four op-amps for the buffered A/D
converter inputs.
The 2.048 V reference voltage is also used to generate the 2.5 V reference for D-REF used
in the digital output circuit.

3.8 Memory
3.8.1 SRAM
The BL2100 module is designed to accept 128K to 512K of SRAM packaged in an SOIC
case. The standard BL2100 modules come with 128K of SRAM.
3.8.2 Flash Memory
The BL2100 is also designed to accept 128K to 512K of flash memory packaged in a
TSOP case. The standard BL2100 modules comes with one 256K 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.
A Flash Memory Bank Select jumper configuration option based on 0 surface-mounted
resistors exists at header JP2 on the RabbitCore module. This option, used in conjunction
with some configuration macros, allows Dynamic C to compile two different co-resident
programs for the upper and lower halves of the 256K flash in such a way that both programs start at logical address 0000. This is useful for applications that require a resident
download manager and a separate downloaded program. See Technical Note 218, Imple-
menting a Serial Download Manager for a 256K Flash, for details.

3.9.1 External Interrupts
The BL2100 is already configured to support exter nal interrupts on pin 1 1 of screw-terminal
header J11. The external interrupt circuit is shown in Figure 22.
Figure 22. Use of Rabbit 2000 External Interrupt
In addition to its primary use as an external interrupt, pin 11 of screw-terminal header J11
may also be used as a CMOS-level digital input or output, or to generate a PWM signal.
When using pin 11 as a CMOS-level digital input or output, use the standard Rabbit 2000
register function configuration for PE5 (on Parallel Port E) to set this pin up for your
intended use. Be aware that there is no provision for protection against voltage spikes
while PE5 is pulled up to Vcc with a 27 k pull-up resistor.
The sample program PWM.C in the Dynamic C SAMPLES/BL2100 directory illustrates
how to use pin 11 of screw-terminal header J11 to generate a PWM signal.
User’s Manual 33
3.9.2 Clock Doubler
The BL2100 takes advantage of the Rabbit 2000 microprocessor’s internal clock doubler.
A built-in clock doubler allows half-frequency crystals to be used to reduce radiated emissions. The 22.1 MHz frequency is generated using an 11.0592 MHz crystal. The clock
doubler is disabled automatically in the BIOS for crystals with a frequency above
12.9 MHz.
The clock doubler may be disabled if 22.1 MHz clock speeds are not required. Disabling
the Rabbit 2000 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. The clock speed will be doubled as long as the crystal frequency is
less than or equal to 26.7264 MHz.
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.
3.9.3 Spectrum Spreader
BL2100 boards that carry the CE mark on their RabbitCore module have a Rabbit 2000
microprocessor that features a spectrum spreader, which helps to mitigate EMI problems.
By default, the spectrum spreader is on automatically for BL2100 boards that carry the CE
mark when used with Dynamic C 7.30 or later versions, but the spectrum spreader 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 unnecessary for the BL2000.
3. Click OK to save the macro. The spectrum spreader will now be set to the state specified by
the macro value whenever you are in the project file where you defined the macro.
There is no spectrum spreader functionality for BL2100 boards that do not carry the CE
mark on their RabbitCore module or when using any BL2100 with a version of Dynamic C
prior to 7.30.

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 BL2100.
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 BL2100. The flash memory and SRAM options are selected with
the 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: An application can be developed in RAM, but cannot run standalone 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 BL2100 and Dynamic C were designed to accommodate
flash devices with various sector sizes.
BL2100s that are special-ordered with 512K flash/512K SRAM memory options have two
256K flash memories. By default, Dynamic C will use only the first flash memory for
program code in these BL2100s. Uncomment the USE_2NDFLASH_CODE macro within
the RABBITBIOS.C file in the Dynamic C BIOS folder to allow the second flash memory
to hold any program code that is in excess of the available memory in the first flash.
User’s Manual 35
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 2000 and
later—see Rabbit’s Technical Note TN257, Running Dynamic C® With Windows Vista®,
for additional information if you are using a Dynamic C release prior to v. 9.60 under
Windows Vista. 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.

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-based 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.
• Execution tracing and symbolic stack tracing.
• 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.

4.1.1 Upgrading Dynamic C
4.1.1.1 Patches and Bug Fixes
Dynamic C patches that focus on bug fixes are available from time to time. Check our
Web site www.rabbit.com/support/ for the latest patches, workarounds, and bug fixes.
The default installation of a patch or bug fix 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 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 a bug fix; of course, you may copy over any programs
you have written. Once you are sure the new patch works entirely to your satisfaction, you
may retire the existing installation, but keep it available to handle legacy applications.
4.1.2 Extras
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.
Starting with Dynamic C version 9.60, Dynamic C includes the popular µC/OS-II realtime operating system, point-to-point protocol (PPP), F AT file system, RabbitWeb, and
other select libraries. Rabbit also offers for purchase the Rabbit Embedded Security Pack
featuring the Secure Sockets Layer (SSL) and a specific Advanced Encryption Standard
(AES) library.
In addition to the Web-based technical support included at no extra charge, a one-year
telephone-based technical support subscription is also available for purchase.

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 BL2100 folder provides sample programs specific to the BL2100. 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), compile it
using the Compile menu, and then run it by selecting Run in the Run menu. The BL2100
must be connected to a PC using the programming cable as described in Section 2.1,
“BL2100 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.”

4.2.3 A/D Converter Inputs
The following sample programs are found in the ADC subdirectory in SAMPLES\BL2100.
• AD_CALIB.C—Demonstrates how to recalibrate an A/D converter channel using two
knownvoltages to generate two coefficients, gain and offset, which are rewritten into
the user block data area. The voltage that is being monitored is displayed continuously .
Make sure that you don't exceed the voltage range of the A/D converter input channel.
NOTE: This sample program will overwrite the calibration constants set at the factory.
• AD1.C—Demonstrates how to access the A/D internal test voltages in both the
TLC2543 and TLC1543 A/D converter chips. The program reads the A/D internal voltages and then uses the STDIO window to display the RAW data.
• AD2.C—Demonstrates how to access the A/D channels using the anaInVolt function. The program uses the STDIO window to display the voltage that is being monitored.
• AD3.C—Demonstrates how to access the A/D converter channels with the low-level

• DAOUT1.C—This program outputs a voltage that can be read with a voltmeter . The output voltage is computed using the calibration constants that are read from the EEPROM
simulated in flash memory.
User’s Manual 39
• DAOUT2.C—This program demonstrates the use of both the D/A and the A/D converters. The user selects both the D/A converter and A/D channel to be used, then sets the
D/A converter output voltage to be read by the A/D channel. All activity will be displayed in the STDIO window.
4.2.5 Using Calibration Constants
The following sample programs are found in the Calib_Save_Retrieve subdirectory
in SAMPLES\BL2100. Note that both sample programs prompt you to use a serial number
for the BL2100. This serial number can be any 5-digit number of your choice, and will be
unique to a particular BL2100. Do not use the MAC address on the bar code label of the
RabbitCore module attached to the BL2100 since you may at some later time use that particular RabbitCore module on another BL2100, and the previously saved calibration data
would no longer apply.
• GETCALIB.C—This program demonstrates how to retrieve your analog calibration
data to rewrite it back to the simulated EEPROM in flash with using a serial utility such
as Tera Term.
NOTE: Calibration data must be saved previously in a file by the sample program
SAVECALIB.C.
• SAVECALIB.C—This program demonstrates how to save your analog calibration coef-
ficients using a serial port and a PC serial utility such as Tera Term.
NOTE: Use the sample program GETCALIB.C to retrieve the data and rewrite it to the
single-board computer.
4.2.6 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 to read and
set the real-time clock
4.2.7 TCP/IP Sample Programs

4.4 BL2100 Function APIs
4.4.1 Board Initialization
void brdInit (void);
Call this function at the beginning of your program. This function initializes the system I/O ports and
loads all the A/D converter and D/A converter calibration constants from flash memory into SRAM for
use by your program. If the LCD/keypad module is installed, this function will turn off LED DS1 to indicate that the initialization was successful.
The ports are initialized according to Table A-3.

4.4.2 Digital I/O
void digOutConfig(unsigned int outputMode);
Each of the BL2100 high-current outputs (OUT00–OUT15) has the capability of being configured in
software as either sinking or sourcing using the digOutConfig function. Execute digOutConfig
at the start of your application to initially set OUT00–OUT15 to be OFF for the type of circuit that you
have, either sinking or sourcing.
To properly set the high-current outputs, you will need to decide for each channel whether the output is
sinking or sourcing. The digOutConfig function will then ensure that each output remains OFF when
the digital output control interface is
until you activate the desired output driver(s)/channel(s) using digOut.
NOTE: The brdInit function must be executed before calling digOutConfig.
NOTE: You must execute the digOutConfig function to set the high-current drivers to be

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 BL2100.
int serMode(int mode);
User interface to set up BL2100 serial communication lines. Call this function after serXOpen().
Whether you are opening one or multiple serial ports, this function mu st be executed aft er executing the
last serXOpen function AND before you start using any of the serial ports. This function is no n-reentr ant.
If Mode 1 is selected, CTS/RTS flow control is exercised using the serCflowcontrolOn and
serCflowcontrolOff functions from the RS232.LIB library.
PARAMETER

Chapter 5 discusses using the TCP/IP features on the BL2100
and BL2110 boards. The TCP/IP feature is not available on
BL2120 and BL2130 versions.
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 Ethernet cables and a hub, or an RJ-45 crossover Ethernet
cable.
The 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 Ethernet cable to connect the BL2100 to a PC that at least has a 10Base-T Ethernet card.
If you have Ethernet access, use a straight through Ethernet cable to establish an Ethernet
connection to the BL2100 from an Ethernet hub. These connections are shown in Figure 23.
User’s Manual 55
Figure 23. Ethernet Connections
The PC running Dynamic C through the serial programming port on the BL2100 does not
need to be the PC with the Ethernet card.
3. Apply Power
Plug in the AC adapter. The BL2100 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 screwterminal header J2.
When working with the BL2100, 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.
56 Smartcat (BL2100)
5.2 TCP/IP Sample Programs
W e 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
BL2100 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_NETMASK, 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 us e an IP
address of 10.1.1.2 for the BL2100 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_CONFIG.LIB library in the LIB\TCPIP directory. More information is available in
the Dynamic C TCP/IP User’s Manual.
IP Addresses Before Dynamic C 7.30
Most of the sample programs use macros to define the IP address assigned to the board and
the IP address of the gateway , if there is a gateway. Instead of the
will see a
MY_IP_ADDRESS macro and other macros.
#define MY_IP_ADDRESS "10.10.6.170"
#define MY_NETMASK "255.255.255.0"
#define MY_GATEWAY "10.10.6.1"
#define MY_NAMESERVER "10.10.6.1"
TCPCONFIG macro, you
In order to do a direct connection, the following IP addresses can be used for the BL2100:
#define MY_IP_ADDRESS "10.1.1.2"
#define MY_NETMASK "255.255.255.0"
// #define MY_GATEWAY "10.10.6.1"
// #define MY_NAMESERVER "10.10.6.1"
In this case, the gateway and nameserver are not used, and are commented out. The IP
address of the board is defined to be 10.1.1.2. The IP address of you PC can be defined
as 10.1.1.1.

Follow these instructions to set up your PC or notebook. Check with your administrator if
you are unable to change the settings as described here since you may need administrator
privileges. The instructions are specifically for W indows 2000, but the interface is similar
for other versions of Windows.
TIP: If you are using a PC that is already on a network, you will disconnect the PC from
that network to run these sample programs. Write down the existing settings before
changing them to facilitate restoring them when you are finished with the sample programs and reconnect your PC to the network.
1. Go to the control panel (Start > Settings > Control Panel), and then double-click the
Network icon.
2. Select the network interface card used for the Ethernet interface you intend to use (e.g.,
TCP/IP Xircom Credit Card Network Adapter) and click on the “Properties” button.
Depending on which version of Windows your PC is running, you may have to select
the “Local Area Connection” first, and then click on the “Properties” button to bring up
the Ethernet interface dialog. Then “Configure” your interface card for a “10Base-T
Half-Duplex” or an “Auto-Negotiation” connection on the “Advanced” tab.
NOTE: Your network interface card will likely have a different name.
3. Now select the IP Address tab, and check Specify an IP Address, or select TC P/IP and

Netmask : 255.255.255.0
Default gateway : 10.10.6.1

5.2.3 Run the PINGME.C Demo
Connect the crossover cable from your computer’s Ethernet port to the BL2100’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 BL2100 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 BL2100 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.
User’s Manual 59
5.2.4 Running More Demo Programs With a Direct Connection
The program SSI.C (SAMPLES\BL2100\TCPIP\) demonstrates how to make the
BL2100 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. LED0 and LED1
on the LCD/keypad module (LED1 and LED2 on the Demonstration Board) will match
those on the Web page. 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\BL2100\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\BL2100\TCPIP\) allows you to communicate with the BL2100 using the Telnet protocol. This program takes anything that comes
in on a port and sends it out Serial Port B. It uses digital input IN00 to indicate that the
TCP/IP connection should be closed, and it uses high-current output OUT00 to indicate
that there is an open connection. You may change the digital input and output to suit your
application needs.
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 BL2100 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/.
If the sample programs ran fine, you are now ready to go on.
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

A.1.1 Exclusion Zone
It is recommended that you allow for an “exclusion zone” of 0.25" (6 mm) around the
BL2100 in all directions when the BL2100 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 BL2100. Figure A-2 shows this “exclusion zone.”

The BL2100 has an option for 0.1" IDC headers, friction-lock connectors, or bottommount sockets at J1, J4, J7, J10, and J13 for physical connection to other boards or ribbon
cables. The holes on the “outside” edges of the connector locations are the holes used by
the friction-lock connectors and by the holes in the bottom-mount sockets.
Figure A-3 shows the BL2100 footprint. These values are relative to one of the mounting
holes. (Two other mounting holes are located under the RabbitCore module.)
NOTE: The same footprint applies for the IDC header and bottom-mount socket options.
Headers J21, J22, and J23 are used to mount the optional LCD/keypad module.

The areas around the crystal oscillator and the battery backup circuit on the BL2100 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. BL2100 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.
NOTE: For more information on conformal coatings, refer to Rabbit Technical Note
TN303, Conformal Coatings, in the online documentation set.

Appendix B describes the power circuitry provided on the
BL2100.
B.1 Power Supplies
Power is supplied to the BL2100 via header J5/J4. The BL2100 is protected against
reverse polarity by a diode at D1 as shown in Figure B-1.
Figure B-1. BL2100 Power Supply
The input voltage range is from 9 V to 36 V. A switching power regulator is used to provide a Vcc of +5 V for the BL2100 logic circuits. Vcc is not accessible to the user.
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
(R29). 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 header
J2/J1, and external connections to digital ground are made on headers J5/J4 and J11/J10.
B.1.1 Power for Analog Circuits
Power to the analog circuits is provided by way of a two-stage low-pass filter, which isolates the analog section from digital noise generated by the other components. The analog
power voltage +V powers the op-amp for the buffered A/D converter inputs, the A/D converter, the D/A converter, and the 4.096 V reference circuit. The maximum current draw
on +V is less than 10 mA. +V is not accessible to the user.

The SRAM and the real-time clock have battery backup. Power to the SRAM and the realtime clock (VRAM) is provided by two different sources, depending on whether the main
part of the BL2100 is powered or not. When the BL2100 is powered normally , and Vcc is
within operating limits, the SRAM and the real-time clock are powered from Vcc. If power
to the board is lost or falls below 4.63 V, the VRAM and real-time clock power will come
from the battery . The reset ge nerator circuit controls the source of power by way of its
/RESET output signal.
A replaceable 265 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 BL2100, and so the expected
shelf life of the battery is
The drain on the battery is typically less than 4 µA when external power is applied, and so
the expected BL2100 battery in-service life is
A long-life 950 mA·h solder-in battery is also provided for in the board layout.

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 CR2330 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 BL2100. Exercise care if you replace the battery
while external power is applied to the BL2100.
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.
B.2.2 Battery-Backup Circuit
Figure B-2 shows the battery-backup circuit located on the BL2100 module.
Figure B-2. BL2100 Backup Battery Circuit
The battery-backup circuit serves three purposes:
• It reduces the battery voltage to the SRAM and to the real-time clock, thereby limiting
the current consumed by the real-time clock and lengthening the battery life.
• It ensures that current can flow only out of the battery to prevent charging the battery.
• A voltage, VOSC, is supplied to U6, which keeps the 32.768 kHz oscillator working
when the voltage begins to drop.
VRAM and Vcc are nearly equal (<100 mV, typically 10 mV) when power is supplied to
the BL2100.

The VRAM switch on the BL2100 module, shown in Figure B-3, allows the battery
backup to provide power when the external power goes off. The switch provides an isolation between Vcc and the battery when Vcc goes low. This prevents the Vcc line from
draining the battery.
Figure B-3. VRAM Switch
Field-effect transistor Q5 is needed to provide a very small voltage drop between Vcc and
VRAM (<100 mV, typically 10 mV) so that the board components powered by Vcc will
not have a significantly different voltage than VRAM.
When the BL2100 is not in reset, the /RESET line will be high. This turns on Q2, causing
its collector to go low. This turns on Q5, allowing VRAM to nearly equal Vcc.
When the BL2100 is in reset, the
/RESET line will go low. This turns off Q2 and Q5, pro-
viding an isolation between Vcc and VRAM.
B.2.4 Reset Generator
The BL2100 module uses a reset generator on the module, U1, to reset the Rabbit 2000
microprocessor when the voltage drops below the voltage necessary for reliable operation.
The reset occurs between 4.50 V and 4.75 V, typically 4.63 V.

Figure B-4 shows a schematic of the chip select circuit located on the BL2100 module.
Figure B-4. Chip Select Circuit
The current drain on the battery in a battery-backed circuit must be kept at a minimum.
When the BL2100 is not powered, the battery keeps the SRAM memory contents and the
real-time clock (RTC) going. The SRAM has a powerdown mode that greatly reduces
power consumption. This powerdown mode is activated by raising the chip select (CS)
signal line. Normally the SRAM requires Vcc to operate. However, only 2 V is required
for data retention in powerdown mode. Thus, when power is removed from the circuit, the
battery voltage needs to be provided to both the SRAM power pin and to the CS signal
line. The CS control circuit accomplishes this task for the SRAM’s chip select signal line.
In a powered-up condition, the CS control circuit must allow the processor’s chip select
signal /CS1 to control the SRAM’s CS signal /CSRAM. So, with power applied, /CSRAM
must be the same signal as /CS1, and with power removed, /CSRAM must be held high
(but only needs to be battery voltage high). Q3 and Q4 are MOSFET transistors with complementary polarity. They are both turned on when power is applied to the circuit. They
allow the CS signal to pass from the processor to the SRAM so that the processor can periodically access the SRAM. When power is removed from the circuit, the transistors will
turn off and isolate /CSRAM from the processor. The isolated /CSRAM line has a 100 k
pullup resistor to VRAM (R28). This pullup resistor keeps /CSRAM at the VRAM voltage
level (which under no power condition is the backup battery’ s regulated voltage at a little
more than 2 V).
Transistors Q3 and Q4 are of opposite polarity so that a rail-to-rail voltage can be passed.
When the /CS1 voltage is low, Q3 will conduct. When the /CS1 voltage is high, Q4 conducts. It takes time for the transistors to turn on, creating a propagation delay. This propagation delay is typically very small, about 10 ns to 15 ns.

Contrast
Adjustment
Starting in 2005, LCD/keypad modules were factory-configured to optimize their contrast
based on the voltage of the system they would be used in. Be sure to select a KDU5V
LCD/keypad module for use with the BL2100 — these modules operate at 5 V. You may
adjust the contrast using the potentiometer at R2 as shown in Figure C-3. LCD/keypad
modules configured for 3.3 V should not be used with the BL2100 because the higher
voltage will reduce the backlight service life dramatically.
You can set the contrast on the LCD display of pre-2005 LCD/keypad modules by adjusting
the potentiometer at R2 or by setting the voltage for 5 V by removing the jumper
was installed at the factory across pins 1–2 on header J5 as shown in Figure C-3. Only one
of these two options is available on these older LCD/keypad modules.
NOTE: Older LCD/keypad modules that do not have a header at J5 or a contrast adjust-
ment potentiometer at R2 are limited to operate only at 5 V, and will work with the
BL2100. These LCD/keypad modules are no longer being sold.
