Hardware Installation
Hardware installation involves configuration of the following Blue Heat/PCI products:
The Blue Heat/PCI; RS-422/485; Opto; Opto RS-422/485; 20mA CL; RJ-11 and Universal Blue
Heat/PCI RS-422/485 adapters
Note: Please see the Software Installation section for
installation of your Blue Heat/PCI or Universal Blue Heat/PCI
Installing the Blue Heat/PCI Adapter in your System
To install your Blue Heat/PCI adapter in your computer follow these steps:
board under certain operating systems.
Your Blue Heat/PCI adapter is very sensitive
to static electricity. Make sure you wear an
anti-static wristband before you remove the
card from the anti-static shipping bag. When
you remove the board from the anti-static
bag, handle it only by the edges and place it
on the anti-static bag or an anti-static mat.
1. Turn the power off to your computer.
2. Open your computer to expose the expansion slots (consult the system documentation for
information on this procedure.)
3. Choose an available 32-bit 5V PCI expansion slot (Blue Heat/PCI; RS-422/485; RJ-11;
Opto; Opto RS-422/485; 20mA CL; Universal Blue Heat/PCI RS-422/485 models) or 3.3V
PCI expansion slot (Universal Blue Heat/PCI RS-422/485 models only).
Note: 3.3V and 5V PCI expansion slots are keyed differently
to prevent incorrect installation of PCI adapters.
4. Remove the screw and the expansion slot cover from the slot you select and save both.
5. Place the Blue Heat/PCI adapter in the expansion slot and push down gently until the card
seats fully in the slot.
Note: Do not force the card into the expansion slot. If you
meet a great deal of resistance remove the board and try
again.
6. Align the mounting bracket and secure the board with the screw that you saved.
7. Close your computer.
Configuration
Peripheral Component Interconnect (PCI) bus architecture offers a feature called Plug and Play
(sometimes referred to as PnP). This feature automatically identifies and configures installed
devices each time the system boots.
In most PCI compliant computers, the system BIOS will automatically detect and configure the
Blue Heat/PCI adapter. However in some cases a system BIOS cannot resolve all of the requests
for resources in the system. This is especially true if you manually assign resources to ISA bus
adapters that the PCI devices need. This often occurs with the assignment of system interrupts,
since this is usually the scarcest resource.
Revision 0.11 14
Blue Heat/PCI User’s Manual, Connect Tech Inc.
If this occurs, the driver will signal that a given resource has not been assigned, which requires
the user to assign system resources manually. Remove the assignments for ISA devices with the
BIOS setup and then reboot the computer. After reboot, determine with the BIOS setup utility
what resources have been assigned to the PCI devices and then do manual assignments of free
resources to ISA devices. Reboot your system. If the BIOS cannot find a suitable configuration
please contact Connect Tech Technical Support.
Baud Rate Selection
Blue Heat/PCI adapters offer ideal solutions for applications requiring serial communications up
to 57.6 Kbps (Blue Heat/PCI CL models), 921.6 Kbps (Blue Heat/PCI RS-422/485; Opto; Opto
RS-422/485; Universal Blue Heat/PCI RS-422/485 models) or 1382.4 Kbps (Blue Heat/PCI;
RJ-11 models). Their baud rates are software selectable, so therefore please refer to the
Software Installation section for configuring the baud rates under certain operating systems.
RS-422/485 Line Interface
The Blue Heat/PCI RS-422/485; Opto; Opto RS-422/485 and Universal Blue Heat/PCI
RS-422/485 adapters come with the RS-422/485 electrical line interface. The RS-422/485
electrical interface is a reliable high-speed serial link that offers superior noise immunity and
multi-drop network connectivity. The RS-422/485 electrical interface is also a superset of the
RS-422 electrical interface. These adapters offer full RS-422/485 support in hardware. The
modes are as follows:
Full Duplex Mode
In this mode, TxD & RxD are active all the time. This mode is typically used in point to point
situations much like RS-232. Please refer to Appendix C: RS-422/485 Line Interface.
Half Duplex Mode
In this mode the TxD line driver is enabled only when data is transmitted and RxD is disabled
when data is being transmitted. This mode is typically used in either point to point "2 wire"
connections OR in multi-drop "2 wire" bus connections. Please refer to Appendix C:
RS-422/485 Line Interface.
Multi-drop Slave Mode
In this mode the TxD line driver is enabled only when data is transmitted and RxD is enabled all
the time. This mode is typically used in multi-drop "4 wire" connections. Please refer to
Appendix C: RS-422/485 Line Interface.
20mA Current Loop Interface
The Blue Heat/PCI CL adapter comes with the 20mA Current Loop electrical line interface. The
20mA Current Loop electrical interface provides a reliable high-speed serial link over a long
distance that offers superior noise immunity and multi-drop network connectivity. Please refer
to Appendix D: 20mA Current Loop Interface.

Connector Box Pinouts
You may order the Blue Heat/PCI (8 port model), Blue Heat/PCI RS-422/485 (8 port, 4+4 and
6+2 models) and Blue Heat/PCI CL with an external I/O Box or the RJ-45 Connector Plug
option. The I/O Box option comes with a metal bracket that can be mounted on a wall or other
surface. When you receive the I/O Box, this bracket is clipped on to the back of the connector
box. If you wish to attach the I/O Box to a wall or other surface, just remove the bracket, fasten
it in place, and then re-attach the connector box. If you wish to set the I/O Box on its rubber feet
only, just remove the bracket from the back. See Figure 9 and Figure 10 for the orientation of
the I/O Box and RJ-45 Connector Plug and Table 9 and Table 10 for the DB-9 pinouts on the
connector box and the RJ-45 pinouts on the plug.

Appendix C: RS-422/485 Line Interface
For information on how to configure your RS-422/485 interface, find your specific Blue
Heat/PCI model below:
Blue Heat/PCI RS-422/485
You can order the Blue Heat/PCI RS-422/485 adapter with all ports RS-422/485 or a
combination of RS-422/485 and RS-232. The RS-422/485 electrical interface is a reliable highspeed serial link that offers superior noise immunity and multi-drop network connectivity. The
RS-422/485 electrical interface is also a superset of the RS-422 electrical interface. The Blue
Heat/PCI RS-422/485 offers full RS-422/485 support in hardware. The modes are as follows:
Full Duplex Mode
In this mode, TxD & RxD are active all the time. This mode is typically used in point to point
situations much like RS-232.
Half Duplex Mode
In this mode the TxD line driver is enabled only when data is transmitted and RxD is disabled
when data is being transmitted. This mode is typically used in either point to point "2 wire"
connections OR in multi-drop "2 wire" bus connections.
Multi-drop Slave Mode
In this mode the TxD line driver is enabled only when data is transmitted and RxD is enabled all
the time. This mode is typically used in multi-drop "4 wire" connections.

Blue Heat/PCI Opto and Opto RS-422/485
The Blue Heat/PCI Opto ships with all ports jumper selectable for RS-232 or RS-422/485. The
Blue Heat/PCI Opto RS-422/485 ships with all ports RS-422/485 only. Both the Blue Heat/PCI
Opto and the Blue Heat/PCI Opto RS-422/485 offer full RS-422/485 support in hardware with
three modes: Full Duplex, Half Duplex, and Multi-drop Slave. You enable these modes via
software. See the
different modes
Electrical Interface Selection
The Blue Heat/PCI Opto adapter provides jumper selectable RS-232 and RS-422/485 electrical
interfaces on each port.
Note:
Blue Heat/PCI Opto RS-422/485 adapters provide only an
RS-422/485 electrical interface on each port. Jumper blocks
J2, J3, J4 and J5 are not present, so therefore please
disregard the following interface selection examples for Blue
Heat/PCI Opto RS-422/485 adapters
Jumper blocks J2, J3, J4 and J5 set the electrical interfaces for the individual ports, with J2 for
Port 1, J3 for Port 2, J4 for Port 3, and J5 for Port 4. Jumpers installed on J2, J3, J4 and J5
enable the RS-232 interface for that port, while jumpers not installed enable the RS-422/485
interface for that port. Figure 6 depicts the locations of jumper blocks J2, J3, J4 and J5.
Example 1:
This example shows the
settings on J2 and J3 jumper
blocks so that port 1 is set for
RS-422/485 and port 2 is set
for RS-232.
Technical Note:
You can set up the RS-232 serial ports to run at up to 230.4
Kbps, but you must use good quality cables to maintain high
baud rates over longer distances.

Full Duplex Mode
In this mode, TxD & RxD are active all the time. This mode is typically used in point to point
situations much like RS-232.
35 Revision 0.11
Blue Heat/PCI User’s Manual, Connect Tech Inc.
Half Duplex Mode
In this mode the TxD line driver is enabled only when data is transmitted and RxD is disabled
when data is being transmitted. This mode is typically used in either point to point "2 wire"
connections OR in multi-drop "2 wire" bus connections. To enable this mode for a port you
must jumper positions 7 and 8 on the appropriate jumper blocks JA, JB, JC, JD. These jumpers
short TxD – to RxD – and TxD + to RxD +. Figure 6 depicts the locations of jumper blocks JA,
JB, JC and JD.
Example
The following example shows the settings on JA, JB, JC and JD
where the RS-422/485 port 1 is set half duplex, the RS-422/485
port 2 is set for half duplex; RS-422/485 port 3 is set for full
duplex or multi-drop slave, and the RS-422/485 port 4 is set for
full duplex or multi-drop slave.

Appendix D: 20mA Current Loop Line Interface
Blue Heat/PCI 20mA CL
The Blue Heat/PCI CL offers a 20mA Current Loop active or passive electrical interface. For
each port there is an optically isolated receiver, an optically isolated transmitter and a 20mA
current source. Optical isolation is functional in passive mode only. See Figure 15 for the
schematic of the 20mA Current Loop module.
Note: The current source uses a compliance voltage of 11 or 22 volts, and the transmitter will
withstand a 27 volt drop. Please refer to the Hewlett Packard Optoelectronics Manual/Catalogue
for a complete description of HPCL 4100 and HPCL 4200 specifications.

To implement an optically isolated passive interface, wire the transmitter and the receiver, while
leaving the current sources unconnected. An external current source is required to implement a
passive interface.
To implement an active interface, connect a 20mA current source in series with the transmitter
and another 20mA current source in series with the receiver. Please refer to Figure 16 for a
20mA Current Loop cable wiring configuration between one port of a Blue Heat/PCI CL adapter
and another port of a Blue Heat/PCI CL adapter. This example shows wiring for both active and
passive modes
Revision 0.11 40

S
● V
= 11V when pins 1 and 2 on jumper blocks J1, J2, J3, J4 J5, J6, J7 or J8 are jumpered

Note:
For most applications, jumpering pins 1 and 2 on the
appropriate jumper block (J1, J2, J3, J4, J5, J6, J7 or J8) will
be satisfactory.
Jumpering pins 2 and 3 on the appropriate jumper block (J1,
J2, J3, J4, J5, J6, J7 or J8) may be required for applications
with multiple/many loads on the Current Loop network.
J1, J2, J3, J4, J5, J6, J7, and J8 are factory set with no

Appendix E: Blue Heat/PCI PTM model
Blue Heat/PCI PTM Adapter
The Blue Heat/PCI Pass Through Mux (PTM) adapter offers two asynchronous RS-232 serial
ports with Monitor Pass Through and Intercept Pass Through capabilities. In Monitor mode the
Blue Heat/PCI PTM adapter allows you to monitor and pass through the data from a device
connected to one serial port to a device connected to the other serial port. This pass through
connection is maintained even if the power or software fails in the computer hosting the Blue
Heat/PCI PTM, but without monitoring capabilities.
In Intercept mode you can monitor, process and then pass through the data from a device
connected to one serial port to a device connected to the other serial port. Once again this pass
through connection is maintained even if the power or software fails, but without
monitoring/processing capabilities.
Features
Two, asynchronous RS-232 serial ports
Supports data communications speeds up to 921 Kbps
A 16C2850 UART controls each port providing 128 bytes of TxD/RxD FIFO buffers
Independent port configuration with baud rates from 50 bps to 921 Kbps; data bits of 5, 6, 7
or 8; stop bits of 1, 1.5, or 2, and odd, even, or stick parity
Monitor Pass Through Mode: you can monitor and pass through data from a device on one
serial port to a device on the other serial port. If power or software fails the serial port
connections will default to direct pass through
Intercept Pass Through Mode: you can monitor, process and pass through data from a device
on one serial port to a device on the other serial port. If power or software fails the serial port
connections will default to direct pass through
Utilizes robust high quality Telecom DPDT relays to achieve direct pass through when power
fails
