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
Revision 0.03 11
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
Figure 1: LED Locations on Blue Heat/Net Sync
Connect Tech Blue Heat/Net Sync User Manual
12 Revision 0.03
Serial Port LEDs
The serial ports LEDs indicate serial activity for each port.
• A flashing LED indicates that the port in question is receiving or transmitting data.
Connecting Serial Devices
V.28 Connections:
V.28 has signaling levels the same EIA RS232.
Basic Async (V.28) RS-232 Null Modem Connection
This is the typical way to connect a Blue Heat/Net Sync to another serial device.

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.

Table 3: Available Special Operations
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.
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.
Figure 11: LED Error Code Example
Connect Tech Blue Heat/Net Sync User Manual
Revision 0.03 19
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.

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.
Connect Tech Blue Heat/Net Sync User Manual
20 Revision 0.03
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.

Revision 0.03 21
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:
Figure 12: Blue Heat/Net Sync Serial Cable Connection Diagram
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.

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

Blue Heat/Net Sync Configuration
The Blue Heat/Net Sync comprises several software components, each of which manages
various functions of the Blue Heat/Net Sync. The following is a breakdown of these
components.
Operating System Software
o Host Operating System Driver
o Configuration Manager
o Web browser (Host Operating System supplied)
Blue Heat/Net Sync Software (Firmware)
o Embedded Operating System (uClinux)
Kernel
Drivers
Ethernet
Serial
Flash
Blue Heat/Net Sync Ethernet Protocol Converter application (Ctid)
Web server (Boa)
Web pages
Telnet services
o PPP Client and PPP Server
o Bootloader
o Serial Configuration Manager (SCM) Application
o Configuration Data Space (CDS)
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
Connect Tech Blue Heat/Net Sync User Manual
24 Revision 0.03
program on a PC).
Configuration Data Space (CDS)
This is the area, in non-volatile (flash) memory, which stores the configuration parameters.
CDS (Configuration Data Space)
Description
The Blue Heat/Net Sync has a number of configuration parameters which are stored in a non-
volatile (flash memory) area. (See appendix for list of parameters).
The CDS area is stored redundantly in the flash memory along with a CRC-style checksum to
ensure data integrity.
Access to CDS Parameters
The parameters stored in the CDS can be changed through the use of the following configuration
tools:
SCM Serial Configuration Manager
WCM Web Configuration Manager
These three methods allow the user to change configuration parameters by the method that is
most convenient. In some cases several methods will be employed during different stages of the
setup of the Blue Heat/Net Sync. For example:
The SCM may be employed in the beginning when the unit is not connected to a network and
various networking parameters need to be set up prior to connection to a network.
WCM may be employed after the unit is connected to a network, possibly to modify other
settings related to serial ports, bootup settings or others.
More information about the operation of the SCM Command Reference and WCM (Web
Configuration Manager) follows.
NOTE: When CDS parameters are changed via the
SCM or WCM some settings will not take effect until the
Blue Heat/Net Sync is rebooted.
Connect Tech Blue Heat/Net Sync User Manual
Revision 0.03 25
SCM (Serial Configuration Manager)
Description
The Serial Configuration Manager is one of the applications you can use to access the
Configuration Data Space (CDS) settings of the Blue Heat/Net Sync. Since the CDS stores the
default serial port settings, it is important that the line mode is configured prior to first use.
Accessing the ports will not be possible otherwise.
Getting Access to the SCM
To access the SCM, simply connect a serial port terminal device (or a PC running a terminal
emulator program) to any of the serial ports on the Blue Heat/Net Sync and enter a correct
Password. A command prompt is then sent to the terminal and CDS parameters can be changed
using a command line style of entry.
Blue Heat/Net Sync has configurable line interfaces. Certain settings can affect access to the
SCM. The ports are scanned as follows:
The default line mode setting of all ports is Undefined. Under these conditions, the first two ports
are set to RS-232 mode during port scanning. Access to the SCM is available through these ports
only (you should set all ports to a known state prior to use).
When a port is set to something other than Undefined, any port with a setting of RS-232 or RS-
485 Full Duplex will be scanned. Otherwise, scanning is not performed and access to SCM is
not available.
NOTE: To access the Blue Heat/Net Sync via the SCM
your serial line interface settings must be at the default
values of 9600 baud, 8 data bits, no parity and 1 stop bit
(9600, 8, n, 1). No flow control is recommended.
In a situation where port scanning is not performed, you can still access the SCM using the push
button reset on the back of the unit. Follow the instructions in the section Activating the Special
Operations Mode and Default Settings to access the SCM in this situation
See the section which describes how the Blue Heat/Net Sync boots for a complete description of
the Bootup process of the Blue Heat/Net Sync and how to access the SCM.
SCM Command Reference
SCM commands are entered as strings of ASCII characters with options separated by whitespace
characters. The entire command line is terminated by a CR character or CR/LF character pair.
Command lines can be entered manually (via a terminal or a PC with terminal emulator
program) or sent from an application program.
If an SCM command is entered with no options specified, the command shows the syntax of its
options and the current setting of those options.

Configure Advanced Serial Settings
The Web Configuration Manager also allows you to configure more advanced serial port
properties. These advanced properties will allow you to configure the XOn Character, XOff
Character, Break Character, Escape Character, Error Character and Event Character, and
Transmit Load Setting for each serial port.
Further, you will be able to specify whether you want to enable Null Stripping or RTS Toggle
for a particular port as well as the option to enable or disable the Break, Event and Error
characters.
By default, all advanced serial properties are disabled. You should only use these advanced
properties if you require them.
You are required to use the ASCII representation of characters using the respective hexidecimal
values. For example, if you wanted your XOn character to be capital 'A', you would specify a
hex value of 41.
We have provided you with an ASCII table on the Advanced Serial Port Properties page for your
convenience. Click on the ASCII Table link, and an ASCII table will open in a new window.
Each serial port parameter has been abbreviated due to space constraints. We have provided

Configure Default Blue Heat/Net Sync
You can choose this option when your Blue Heat/Net Sync still has a factory default IP address
of 192.168.42.1. It will launch the Web Configuration Manager for this IP address, enabling
you to configure your Blue Heat/Net Sync as outlined in the Web Configuration Manager.
Figure 27: Add or Auto Discover Blue Heat/Net Sync Menu Screen
Add New Blue Heat/Net Sync
You can add a Blue Heat/Net Sync by specifying its IP address or MAC address.
If you specify an IP address, the Configuration Manager will connect to that specific Blue
Heat/Net Sync and the configuration information for installation. If it cannot connect, it will not
install the unit. The Blue Heat/Net Sync may get the IP address from DHCP server or it can be
manually fixed. The Configuration Manager will use 49152 as the default TCP port. This value
is configurable.
If you specify a MAC address (located on the underside of the device), the Configuration
Manager will use the auto-discover mechanism to retrieve the information for installation. The
auto-discover mechanism uses UDP broadcast, so the unit must be located on the local network
to install via MAC address. The Configuration Manager will use 49152 as the default UDP port.
This value is configurable.
Figure 28: Add Blue Heat/Net Sync Screen
Connect Tech Blue Heat/Net Sync User Manual
46 Revision 0.03
Auto Discover Blue Heat/Net Sync
The auto discover will broadcast a message to all the Blue Heat/Net Sync devices on your
network. Upon receiving the broadcast packet, the Blue Heat/Net Sync device will respond.
Click the Auto Discover button to search for Blue Heat/Net. The searching domain can be
changed by checking Use Specific Broadcast IP and entering an IP address domain in the IP
address box. The broadcast packet will use the default UDP port 49152, but it can be changed in
the Blue Heat/Net Sync configuration. The Stop button will end the search.

directory of a local FTP server. If you do not have a local FTP server, contact your system
administrator to set one up.
Upgrade using SCM (Serial Configuration Manager)
The SCM method of upgrading is used when the Blue Heat/Net Sync does not boot properly.
You can reinstall your original firmware from the supplied CD, or you can download any newer
versions that exist from the CTI website in the
http://www.connecttech.com/asp/Support/DownloadZone.asp or go directly to the FTP site as
indicated below.
You will need the use of a TFTP server. (Contact your system administrator to obtain access to
a TFTP server). Download the most recent firmware components from the FTP site
ftp://ftp.connecttech.com/pub/BHN/ . These files include BHNuClinux_X.XX.gz,

Msk1: On writes, set this bit to mask bits 14..8. This prevents previous settings of bits 14..8 from being changed.
MP: Minute Pulse (read only): Current State of Minute-Pulse signal (at the time of the read).
MPP: Minute Pulse Pending (read only): This bit is set to the same state as the MPO bit (when the MPO bit is written). When the MPO is
written high, this bit goes low (=0) when the next selected Minute-Pulse edge occurs.
MPO: Minute Pulse Once: When low (=0), the selected Minute-Pulse edge always resets the Seconds value. When high (=1) the RTC
increment is inhibited, then when the first selected Minute-Pulse edge occurs, the Seconds value will be zeroed, the MPP bit will be
cleared and the RTC increment will be enabled. All subsequent Minute-Pulses edges will be ignored.
IntEN: Clock Interrupt Enable: Enable an interrupt to occur on each clock increment pulse. The Interrupt is cleared by reading (or writing) the
RTC Lower Word (the Minutes/Seconds counter) or by disabling the interrupt. There is a dedicated interrupt signal to the Coldfire for
the RTC interrupt.
SE: Seconds-Pulse Edge Select: Selects the edge (of the Seconds-Pulse) which causes the RTC increment, 0=falling, 1=rising.
EXT: External Time Base Select: 0=Internal Timebase (1 Hz), 1=External Timebase.
ME: Minute Edge select: Selects the edge (of the Minute-Pulse) which causes the RTC Seconds counter to be reset, 0=falling, 1=rising

Important Note: These control bits are transferred to ALL the Line Interface PLD‟s by a serial interface. On each write to any of the 4 control registers, a serial
transfer is started. The transfer takes about 16uS to complete. During this time NO write can occur to any of the 4 registers. A Busy signal is available to indicated
that the transfer is in progress. (See the PLD_STATUS Register, below).
Basic Line Mode Control bits:
SP[2..0] SP508 Line Mode setting bits: See information in SP508 Data sheet. Power-up state=[111].
SPT SP508 Terminator Enable: 0=disable terminator, 1=enable terminator

Protocol Descriptions
The Blue Heat/Net Sync supports a variety of protocols. The following is a brief explanation of
each and how they are implemented.
ARP
Address Resolution Protocol, a method used to find a unit‟s Ethernet MAC address from its
Internet address.
BOOTP
Bootstrap Protocol, a protocol that allows a unit to boot from the network instead of using
information stored on the Blue Heat/Net Sync (typically in Flash memory).
DHCP
Dynamic Host Configuration Protocol, a protocol that provides a means to dynamically
allocate IP addresses to computers on a local area network. The system administrator assigns
a range of IP addresses to DHCP and each client device on the Local Area Network requests
an IP address from the DHCP server. The request and grant process uses a lease concept with
a controllable time period. The Blue Heat/Net Sync offers this as a configurable option; it
can either be turned on or the user can set a fixed IP on the unit.
HTTP
HyperText Transfer Protocol, a standardized Protocol that Web Browsers use to connect to
web pages. It is used to provide web based configuration tools on the Blue Heat/Net.
IP Internet Protocol, a common addressing scheme for modern networks. Used in conjunction
with TCP to form TCP/IP (see below)
RARP
Reverse Address Resolution Protocol, a method to find a unit‟s Internet address from a MAC
or Ethernet address.
TCP
Transmission Control Protocol, a lossless protocol, requiring a handshake to insure that data
is not lost during transmission. Used in TCP/IP to form the main data transfer pathway
between Blue Heat/Net Sync units and the host computer.
Telnet
A terminal-protocol that can be run over TCP/IP to connect to a remote unit. It is one of the
methods used to configure the Blue Heat/Net Sync unit.
TFTP
Trivial File Transfer Protocol, a protocol used to download firmware to the Blue Heat/Net.
UDP
User Datagram Protocol, a protocol used when handshake is not critical. It is used by TFTP
(see above) and for auto discovery of the units.

Common Configuration Setups
Static IP Setup
In some networking environments it is best to have the IP address set to a fixed value. The
advantage is that since it is fixed, connecting to it can be a lot simpler.
Static IP is often the best choice if you are trying to connect via WAN or through a Firewall. It
can be difficult to resolve the Blue Heat/Net Sync‟s IP address if you use DHCP in this instance.
The default configuration is a static IP of 192.168.42.1. In most cases this will not be the address
you want to use in your network. You can change it using two different methods:
Serial Configuration Manager (SCM)
A direct serial connection to on of the serial ports on the Blue Heat/Net Sync.
Or
Web Configuration Manager (WCM)
Using a web browser like Internet Explorer to connect to the unit.
Refer to the manual sections for specific details on using the SCM and WCM.
Example:
You want to configure a static IP on a Blue Heat/Net Sync of 198.182.196.15. The network‟s
server is at 198.182.196.1 and the gateway is 198.182.196.2. The subnet mask is 255.255.255.0.
Using SCM
Log onto the Blue Heat/Net Sync. There is no login necessary if using SCM. The default
password for the SCM is password.
Enter net net=198.182.196.0. This will set 198.182.196.0 to the server, gateway and the unit‟s IP
in one step.
Enter net my_ip=15. This will set the unit‟s IP to 198.182.196.15.
Enter net server_ip=1. This will set the server IP to 198.182.196.1.
Enter net gateway_ip=2. This will set the gateway IP to 198.182.196.2.
Enter net subnetmask=255.255.255.0. This will set the subnet mask.
Enter net dns_ip=3. This will set the DNS IP to 198.182.196.3
Enter net dhcp=no. This will turn off DHCP on the unit.
Enter save. This will save the configuration set above to flash memory.
Enter exit. The unit will reboot using the new settings.
Using WCM
Connect to the Blue Heat/Net Sync using a web browser by entering the current IP of the unit in
the address.
Log on by supplying the username and password. The default login is wcm and the default
password is password.
Select the Blue Heat/Net Sync Settings page and fill in the server IP, Blue Heat/Net Sync IP,
Gateway IP, DNS IP and subnet mask as defined above.
Ensure the Use DHCP option is set to no
Click on the Save to Flash button to store the changes.

DHCP Setup
In many modern networks IP numbers are not static but are automatically assigned by a DHCP
server and can change over time or on each power up.
DHCP must be enabled on the Blue Heat/Net Sync because it is shipped to use a default static IP
(192.168.42.1)
Using SCM
Log onto the Blue Heat/Net Sync. The SCM does not require a login. The default password for
the SCM is password.
Enter net dhcp=yes. This will turn on DHCP on the unit.
Enter net dns_ip=3. This will set the DNS IP to 198.182.196.3
Enter save. This will save the configuration we just set to flash memory.
Enter exit. The unit will reboot using the new settings.
How the Blue Heat/Net Sync Boots Up
Each time the Blue Heat/Net Sync is powered-up or rebooted with an appropriate command, a
certain sequence of software execution occurs.
The Booter runs from flash memory first. Its job is to perform the following:
Setup the embedded processor
Validate at least one of the redundant Loaders (via a CRC check).
Load a validated Loader into RAM memory.
Run the Loader.
If the Booter discovers that both Loader programs are defective (erased or faulty CRC
calculation), an error code is displayed on the LEDs of the Blue Heat/Net Sync.
The Loader runs from RAM memory. Its job is to perform the following:
o Update any required CDS items.
o Determine if the SCM application will be entered. This is accomplished by
scanning the designated serial ports, for a period of time, to determine if a
correct password is entered. If the password is found the SCM application will
be entered. (see the SCM Command Reference command for details of these
settings).
o Locate, load and run an Operating System (uClinux). (As shown in the
following boot-up flow chart).
o Run the main Operating System (uClinux).
o Operating System launches port personality default ctid

Asynchronous Communications Tutorial
The Blue Heat/Net Sync features four synchronous/asynchronous serial communication ports.
Asynchronous communication is a simple, cost effective means of terminal serial
communication. For this reason, it is widely used for communications on personal computers,
bar codes readers, printers, terminals and much more. The following documention represents a
basic tutorial for asynchronous communications. For a tutorial on synchronous communications,
please refer to the Z16C32 IUSC User’s Manual (DOC ID DC8292) on the Zilog website.
In asynchronous serial communication, the electrical interface is held in the idle position
between characters, also referred to as “mark”. A change in signal level (known as space level)
indicates the start of transmission of a character. The receiver recognizes this change as a “start
bit”. Once the start bit has been sent, the transmitter sends the actual data bits. In typical
asynchronous communications there may be 5, 6, 7, or 8 data bits, depending on the application.
Both the receiver and the transmitter must be set to the same number of data bits, baud rate and
stop bits. Stop bits can be 1, 1.5, or 2 bit periods in length. When the transmitter has sent all the
data bits, it sends a stop bit. This stop bit signals to the receiver that the data has finished
transmission. The stop bit is the same state as the idle or mark state.

Serial Line Interface Tutorial
RS-232 Line Interface:
RS-232 is the simplest, least expensive line interface standard, the Sipex tranceivers used on the
Blue Heat/Net Sync refer to RS232 as V.28 mode. It is also referred to as EIA232 and TIA/EIA-
232. The RS-232 specification signals levels of +3V to +15V for a logic 0 or Space, and -3V to -
15V for a logic 1 or Mark. The Blue Heat/Net Sync has RS-232 signal levels with a typical
range of +/- 8 Volts. The maximum cable length you can use with RS-232 is dependant on a
number of factors including:
Baud rate: The higher the baud rate, the shorter the cable length must be.
Cable quality: Quality largely refers to the capacitance of the cable. A higher capacitance
(usually specified as pF or pico Farads per foot) dictates a lower baud rate, and a shorter
maximum length. Low capacitance computer cables for RS-232 applications are available from
all wire and cable suppliers.
You can usually operate with cable lengths of up to 100 feet (30 m) at baud rates up to 115.2
Kbps using low capacitance cable. For higher baud rates such as 230.4 Kbps and up, we
recommend keeping the cable lengths to within 25 feet (7.6 m).
The TIA/EIA232 specification specifies two connectors: the DB-25 and the DB-9. Each of these
connectors has a standardized pinout. Refer to the Pinouts section of the manual for the DB-25
RS-232 (V28) pinout.
Differential Line Interfaces:
The Blue Heat/Net Sync features Sipex SP508 multi-protocol transceivers. These transceivers
features the following differential line standards.
V.11: A differential line interface with signal levels compatible with RS-485 and RS-422.
V.10: A single ended line interface that can be wired such that it will have some of the noise
cancelling features of RS485 (V.11). This interface is also called RS-423.
V.35: A differential line interface that operates in a current loop. The electrical levels are about
+/- 550mV.
RS485/RS422/V.11 Details
V.11, RS-485, or TIA/EIA485, is a differential line interface standard capable of high baud rates
over long cables. The Sipex tranceivers used on the Blue Heat/Net Sync refer to RS-485 as V.11

mode RS-485 is fully compatible with RS-422; which is considered a subset of RS-485.
The use of differential transmitters and receivers ensures RS-485 communications are reliable
and robust. This means two wires are used to transmit or receive a signal. One wire carries the
true or non-inverted signal; the other wire carries the inverted signal. The non-inverted signal is
labelled with a (+) and the inverted is labelled with a (-). The differential communication refers
to the (+) as “TXB” and the (-) as “TXA”.
Any noise injected into the wires is cancelled at the receiver, leaving only the original,
undistorted data signal. Twisted pair cables are always used in RS-485, this ensures that the
communications are robust and as error free as possible. RS-485 signal levels are between 0 and
5 Volts, the differential voltage can be as little as 200mV.
Differential can operate in three different modes: a 4-wire full duplex interface, 4-wire multi-
drop full duplex interface and a 2-wire half duplex interface. A full duplex (bi-directional)
differential communication interface requires at least four wires, two for transmit and two for
receive. A half duplex interface only requires two wires, this provides a cost effective cabling
solution.
Multi-drop is a great feature of RS-485. Multiple RS-485 devices can be bussed together in a
daisy chain type fashion to create a network. Up to 32 devices may be connected together on the
same network. In multi-drop networks, one of the devices (usually the computer) is designated
as the master, and all the other devices are designated as slaves. All communication is initiated
by the master. The master and slave designations are established by your communications
application.
Basic 4-Wire, Full Duplex Communications:
In a 4-wire RS-485 network, two devices are connected together, for example your Blue
Heat/Net Sync RS-485 port and an RS-485 device.
Connect Tech Blue Heat/Net Sync User Manual
74 Revision 0.03
Multi-drop 4-Wire, Full Duplex Communications:
In a multi-drop 4-wire differntial network, two to 32 devices are connected together. Note that
each RS-485 receiver counts as a device or “load”. In this multi-drop mode of communication, a
master slave protocol must be enforced, that is, all communication is initiated by the master, in
this case a Blue Heat/Net Sync. The communication is “full duplex”, meaning that receive and
transmit traffic occur on different pairs of wires. The Blue Heat/Net Sync can receive and
transmit data from/to a device at the same time.
Basic - Wire, Half Duplex Multi-drop Connection:
In a 2-wire differntial network, two to 32 devices are connected together. Note that each receiver
counts as a device or “load”. In this multi-drop mode of communication a master slave protocol
must be enforced, that is, all communication is initiated by the master, in this case a Blue
Heat/Net Sync. The communication is “half duplex”, meaning that receive and transmit traffic
occur on the same wire. The Blue Heat/Net Sync and devices can not receive data and transmit
data at the same time.
Note that the Receiver +/- and the Transmitter +/- signals are connected together. This is
performed at the DB-9 connectors. All communication between devices occurs over a single pair
of wires; this can lower the cost of wiring your network.

Bus Contention on Differential Multi-drop Networks:
Bus contention occurs when two or more devices enabled on a bus attempt to run the bus to
opposite logic values. From the diagram above, we can see that there are multiple differential
transmitters (TXD) on the bus. To avoid the bus contention problem, the differential transmitter
features a tri-state, or high impedance mode controlled by an input pin (enable). Software and
hardware in the Blue Heat/Net Sync and the differential devices will always place its transmitter
into the high impedance mode when not transmitting. This feature is managed by the Blue
Heat/Net Sync and is fully transparent to your application.
For example, in a multi-drop network, the differential transmitter is enabled prior to the master
initiating transmission. When transmission is complete, the transmitter is placed in high
impedance mode. Each slave will receive that transmission from the master. (A protocol must be
in place to address, or select, the desired slave device, but that discussion is beyond the
intentions of this tutorial, and is entirely application dependent). When the slave device has
received the data, it will respond by enabling its transmitter and transmitting data onto the bus,
then placing its transmitter into high impedance mode, just as the master did.

Termination Resistors in Differential Networks
Termination Resistors in Differential Networks:
Differential networks often benefit from the installation of termination resistors. Termination is
rarely required for lower baud rates, for example 9600 baud or less. However, differential
networks are transmission lines, and can suffer from the electrical effects of ringing, or
undershoot and overshoot, all of which can cause data errors, especially at higher baud rates, like
115.2 Kbps. Termination resistors should always be installed at the extreme ends of the network,
as close to the differential transceiver circuits as possible, as outlined in the diagram below.
NOTE: The Blue Heat/Net Sync features software
selectable termination.
