Connect Tech Blue Heat/Net Sync User Manual
Understanding Virtual COM Ports
In a typical serial port setup, the application communicates directly with the connected serial
port hardware.
Virtual COM ports differ in that the application communicates with a network protocol layer that
transfers the necessary information to and from the remote serial ports. The virtual ports appear
as standard serial ports to the application, but in reality the data is translated into a series of
Ethernet messages between the Blue Heat/Net Sync unit and the host computer. The serial port is
not physically connected to the host computer, but this is transparent to the application trying to
access it.
There are several advantages to using virtual COM ports, which include:
Distance – The serial ports can be a great distance away from the host computer. They are
not limited by the standard electrical characteristics of the RS-232 or RS-422 interface
because the primary data transfer is being done via Ethernet. Depending on the set up, these
serial ports can be at a different location and the Internet can act as the carrier of the serial
port traffic.
Speed – Short RS-232/422 cable lengths can be used with the primary distance relying on
the network connection. The capacitance of long lengths of serial cable does not limit data
speeds in these cases.
Cabling – Cost effective Ethernet cabling can be used for the transfer of information to the
Blue Heat/Net Sync and often this is part of the existing networking infrastructure.
Connecting serial ports in a remote location can be as easy as plugging in a Blue Heat/Net
Sync to the Ethernet network. This provides a simple, clean cabling arrangement.
Port Sharing – In some applications it is desirable to have a serial resource that is accessed
and shared by more than one host computer. Connect Tech‟s virtual serial port technology
allows this to be done easily.
Routing – Different ports on a Blue Heat/Net Sync can be connected to multiple host
computers.
Monitoring – Because the virtual serial ports are on the network, they can easily be
monitored to ensure everything is operating correctly.
Blue Heat/Net Sync Installation Overview
There are three main stages in the installation process for your Blue Heat/Net Sync.
1. Hardware Installation
This involves the physical connection of the Blue Heat/Net Sync hardware to your
network, and addresses issues such as cabling and power requirements.
2. Blue Heat/Net Sync Configuration
The first step in the configuration process is to set the IP Address. Then use one of three
available methods to configure the Blue Heat/Net Sync firmware settings for your
application. This can be done through the SCM (Serial Configuration Manager) or the
WCM (Web Configuration Manager), depending on circumstances and personal
preference.
3. Software Installation for Windows
This step installs and configures the Blue Heat/Net Sync drivers and ports for your host
Operating System and allows you to set parameters specific to your serial requirements.
This is done via the Blue Heat/Net Sync Configuration Manager.
NOTE: Software support for Windows and Linux is still in
development

Connect Tech Blue Heat/Net Sync User Manual
Hardware Installation
Connecting the Blue Heat/Net Sync to Your Network:
Before you begin, take a minute to ensure that your package includes the required components
for your Blue Heat/Net Sync:
One Blue Heat/Net Sync unit
•
One power supply
•
One CD containing software and documentation
•
One Phoenix contact screw terminal plug PN: 1847055
•
One RJ-45 cable (optional)
•
If any of these components is missing, contact Connect Tech or your reseller.
Ethernet LEDs
The front panel of the Blue Heat/Net Sync features Ethernet and serial port LEDs to monitor
activity.
Power: When this LED is on, the Blue Heat/Net Sync is receiving power.
CPU: Once the uClinux firmware is booted and running correctly, this LED lights up.
10/100: This LED represents the line rate at which the Blue Heat/Net Sync is connected
to your network.
LED on = a 100 megabit connection.
LED off = a 10 megabit connection.
(The Blue Heat/Net Sync automatically detects the line rate of your network).
L/A: This light illuminates when the connection to your network or computer is
achieved.
A blinking light indicates that Transmit (Tx) or Receive (Rx) activity is detected
on the Ethernet cable.
FD: Indicates that your network is running in full duplex or half duplex mode:
ON = full duplex, OFF = half duplex

RS-422/V.11 Connections
The following are basic connections that can be accomplished when the I/O levels are in V.11 (RS-
422) mode. V.11 mode signaling can be enabled with EIA-530, RS-449 or X.21 modes on your Blue
Heat/Net Sync.
Figure 5: Basic RS-422/V.11 Asynchronous Connections
Figure 6: Basic RS422/V.11 Synchronous Connections
NOTE: Blue Heat/Net Sync clock signals are bidirectional. The
Blue Heat/Net Sync can either source or receive a clock. See Blue
Heat/Net Sync Clocking for more details.
Blue Heat/Net Synchronous Clocking
The clocking circuits on the Blue Heat/Net Sync are very flexible. The Blue Heat/Net Sync DB-25 clock
pins are bi-directional. This means that the TXC or RXC pins can be inputs receiving a clock or outputs
driving a clock. Functionally the two pins are equal. For example, the following clocking combinations are
possible:
RXC as clock input and TXC as clock input.
RXC as clock output and TXC as clock output.
RXC as clock input and TXC as clock output.
RXC as clock output and TXC as clock input.
The Blue Heat/Net Sync receivers and transmitters can be clocked independently from any combination of
the above or from internal clock sources.
Clocking is also available from the EXT_REF_CLK input pin on the DB-9 female.

Activating the Special Operations Mode and Default Settings
Blue Heat/Net Sync includes a push button on the rear of the unit beside the DC power
connector. This push button can be used to perform special operations such as resetting the unit
to its default settings or forcing port scanning in situations where the SCM is not accessible.
Using the Reset Button to Activate the Special Operations Mode
To activate the Special Operations Mode, hold the reset button while the unit is powering up.
Hold the button until all the port LEDs blink rapidly and then release the reset button. The port
LEDs will continue to flash rapidly after the reset button is released to indicate the Special
Operations Mode is active.
Selecting a Special Operation
Once the Special Operations Mode has been activated, four operation options are available:
1. Abandon the Special Operations Mode
To abandon the Special Operations Mode without selecting a special operation, press
and hold the reset button for at least four seconds. While the button is pressed, the
rapid flashing of the port LEDs will stop. After four seconds, the rapid flashing will
resume and the reset button can be released. After the release of the reset button, the
port LEDs will turn off, indicating that the Special Operations Mode has terminated.
2. Cancel a Special Operation
If you need to cancel a special operation after it has been selected, repeatedly press the
reset button until all the port LEDs begin to flash rapidly. Then abandon the Special
Operations Mode by pressing the reset button for four seconds, as explained above.
3. Select a Special Operation
Operations are selected by repeated short presses of the reset button. Each time the
reset button is pressed it is counted and represented on the port LEDs as a binary
number with the port 1 LED as the least significant bit (see Table 1). Choose the
operation which you want to perform. If you miss the selection that you want, keep
pressing the button. The count starts over again once it reaches 7 (1111 binary).
4. Activate a Special Operation
To activate a selection, press and hold the reset button for at least four seconds. During
this time the rapid flashing of the port LEDs will stop. Once the rapid flashing resumes
you can release the reset button. The port LEDs will turn off indicating that the Special
Operations Mode has been activated.

Special Operation
Number of presses (and binary
representation)
Usage
Force port scanning to
first two ports
(Scanning runs until
current scanning delay
setting times out. Default
is 30 seconds).
ONE press
This forces the first two ports to RS-232
mode, causing the SCM to scan these ports
and thereby allowing access to the SCM (see
note below).
Force port scanning to all
ports.
(Scanning runs until the
SCM is entered or until
the unit is powered
down. There is no time
out).
TWO presses
This forces all ports to RS-232 mode,
therefore all ports are scanned for SCM use.
The Blue Heat/Net Sync will behave in the
same manner as an RS-232 only model (see
note below).
Restore factory default
settings
SEVEN presses
This restores the factory default settings for
ALL configuration parameters.
Table 3: Available Special Operations
NOTE: Why would I need to force port scanning?
Some line interface settings are inappropriate for SCM use.
During boot up, the SCM scans only those ports set for RS-232
mode. If all of the ports are configured for another mode, (1/2
Duplex or Multi-drop) SCM port scanning is bypassed, and the
SCM application cannot be accessed. Use of either of the “Force
Port Scanning” operations outlined in Table 1 will force port
scanning to occur so the SCM application can be accessed.
Power On Diagnostics:
LED Error Codes
If an error is detected during the bootup process, an error condition and code are displayed on
the LEDs on the face of the Blue Heat/Net Sync.
The error condition is signaled by a rapidly flashing CPU LED (about 10 to 20 per
•
second).
The error code is displayed on Port LEDs 1 to 4 as a binary number.

Error Code and Event
Details
Suggested Corrective
Action
1. Loader code in flash is erased.
The regions of flash memory which hold
the loader code are both erased. (There
are two redundant loaders in flash that
can be run).
This may occur in when
there are ESD
disturbances or in
electrically noisy
environments. If this error
persists it may be a
hardware issue.
Contact Connect Tech.
2. Loader code in flash has a bad CRC.
The regions of flash memory which hold
the loader code both have CRC errors.
(There are two redundant loaders in flash
that can be run).
See corrective action for
error code 1.
3. RAM copy of loader code has a bad
CRC.
The loader code is copied to RAM
before execution. This error is shown if
the RAM copy has a CRC error.
See corrective action for
error code 1.
4. Configuration Data Space (CDS) areas
have corrupted data (CRC failure).
The CDS is copied from flash to RAM
during the beginning of the loader code.
If a CRC error is detected in the RAM
copy, this error is shown.
See corrective action for
error code 1.
In the above example, a rapidly flashing CPU LED during the boot up process signifies the Blue
Heat/Net Sync has experienced an error. Port LEDs 1 through 4 signify which error has
occurred. In this case, LED 2 and 3 are on, so the error code is 6. The chart below defines the
error details for each error code.
Table 4: LED Error Codes for Blue Heat/Net Sync
Revision 0.03 19
Connect Tech Blue Heat/Net Sync User Manual
5. Cannot obtain an operating system
image (uClinux) to run.
This will occur when any of the enabled
boot sources (flash or BOOTP/TFTP or
TFTP) fail to obtain a valid compressed
operating system image to run.
Check network
connections, server
computer or your unit's
settings.
This error occurs if TFTP
booting is enabled and the
Blue Heat/Net Sync
cannot download the file
from the server.
Contact Connect Tech if it
persists.
6. Unexpected return from the uClinux
operating system.
This error occurs if the operating system
returns back to the loader.
See corrective action for
error code 1.
7. CDS re-programming failure.
Certain CDS items are updated during
the bootup. If a failure occurs during the
re-programming of the flash, this error
will occur.
See corrective action for
error code 1.
8. Boot count could not be incremented
in flash memory
This error is usually caused by a Flash
memory failure.
Contact
Connect Tech.
9. No ports found
This message usually indicates a UART
component failure.
Contact
Connect Tech.
20 Revision 0.03
15. Mismatched CDS version number
uClinux checks the CDS version number
against its expected CDS version
number. If they are different, uClinux
does not continue its operation.
If you have updated the
uClinux code via SCM
and have not updated the
loader/SCM code, this
error appears on reboot.
Update companion loader
code and reboot.

SCM Cabling requirements
SCM: Serial Configuration Manager
The Serial Configuration Manager is used to configure the Blue Heat/Net Sync via a serial port
and is discussed in greater detail later in this document. To access the Serial Configuration
Manager you will need to connect an RS-232 (V.28) serial cable from your standard computer
serial port to any RS-232 (V.28) port on the Blue Heat/Net Sync. The cabling required to
connect to the Blue Heat/Net Sync is as follows:
Connect Tech Blue Heat/Net Sync User Manual
The key signal connections are RX, TX and GND. The other signals may not be required in your
application. If you are assembling your own SCM cable, we recommend that all of the above
connections be made.
Setting a Static or Dynamic IP Address
Prior to configuring the Blue Heat/Net Sync, you must set a static or dynamic IP address. The
default IP address of a new Blue Heat/Net Sync is 192.168.42.1. If there is a possibility that this
has been changed, you will need to find the current IP address setting before you begin.
The easiest way to get the IP address of your Blue Heat/Net Sync is as follows:
Follow the steps outlined in the section Installing the Blue Heat/Net Sync Configuration
Manager and noting your Blue Heat/Net Sync‟s IP number (i.e. A.B.C.D) using the Auto
Discover Blue Heat/Net Sync feature.
Revision 0.03 21
Figure 12: Blue Heat/Net Sync Serial Cable Connection Diagram
Connect Tech Blue Heat/Net Sync User Manual
Set the IP Address Using the Web Configuration Manager
NOTE: If you use the Windows Configuration Manager
and use Auto Discover to locate your Blue Heat/Net
Sync on the network, you can right-click and launch the
Web Configuration Manager from there.
You only need to use the route add command if you
choose not to use the Configuration Manager found on
the CD that accompanied your Blue Heat/Net Sync unit.
From the command prompt of your computer, run: route add A.B.C.0 mask 255.255.255.0 <current
IP of your host machine> Be sure to replace the .D from the Blue Heat/Net Sync‟s IP with a 0
(zero). Open your browser and put the Blue Heat/Net Sync‟s IP in the address bar (i.e. A.B.C.D)
This will open the WCM. Log in (default login is wcm and the default password is password)
and assign the static IP or change the IP to 0.0.0.0 if you are using a DHCP assigned IP.
Set the IP Address Using the Serial Configuration Manager
Insert your CD into the computer and complete the following steps:
1. Once your CD has been inserted, the Driver/Software Installation menu should appear. If it
doesn‟t, double-click on ctisetup.htm.
2. Click View in the Blue Heat/Net Sync Software section and then Connect in the Serial
Configuration Manager section. This will launch HyperTerminal that comes with Windows XP.
3. Unplug the power to the Blue Heat/Net Sync and plug it back in. Light indicators 1 to 4 will
blink sequentially. This sequential flashing will last for 30 seconds. You must log in during
this window.
4. During this sequential flashing, type the word password into the HyperTerminal window. Be
careful you do not miss the window of opportunity to enter the password.
5. You now have access to the Serial Configuration Manager (SCM). An scm> prompt is ready
to accept commands. If you do not see this prompt, unplug the power and repeat the steps above.
If you wish to set a dynamic IP address enter the following:
net dhcp=yes
save
exit
If you wish to set a static IP address, enter the following, substituting xxx.xxx.xxx.xxx with the
static IP you wish to assign:
net mip=xxx.xxx.xxx.xxx
save
exit
Close the HyperTerminal. You may now disconnect the DB-25 cable from your PC and connect
it to any serial device
.

The following section describes in brief what each main component controls.
Host Operating System Driver
The host operating system driver performs the translation from a standard serial COM port
interface to the Blue Heat/Net Sync protocol (which is then delivered to the LAN as described
above).
Configuration Manager
This software manages and configures the relationships between the Blue Heat/Net Sync serial
ports and the COM port assignments of the Host Operating System.
Web Browser
The host operating system supplies a Web Browser to support the Web Configuration Manager
(WCM) used to change the configuration settings of Blue Heat/Net Sync units.
Embedded Operating System
The embedded operating system is uClinux.
Bootloader
This code first starts up the embedded processor of the Blue Heat/Net Sync from a power-up or
software initiated reboot. It then obtains the embedded operating system image (file) from one of
several locations and runs the operating system.
Serial Configuration Manager (SCM) Application
This application is used to change the configuration settings of Blue Heat/Net Sync units by
connecting to a serial port on the Blue Heat/Net Sync from a terminal (or terminal emulation
