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.
Line Bias/Termination
On the Blue Heat/PCI RS-422/485 the RS-422/485 receivers are biased high through fixed resistors. Please refer to Figure 11 for a partial schematic.
Universal Blue Heat/PCI RS-422/485
Universal Blue Heat/PCI RS-422/485 adapters offer full RS-422/485 support in hardware like the other Blue Heat/PCI RS-422/485 models. The modes include full duplex, half duplex, and multi-drop slave. Universal Blue Heat/PCI RS-422/485 adapters offer the following additional functionality:
Tri-state Control
Universal Blue Heat/PCI RS-422/485 adapters allow you to tri-state the line drivers on power up. To tri-state the drivers on power up please ensure there is no jumper installed across the pins on jumper block JI. Refer to Figure 3 for the location of J1.
Line Bias/Termination
On the Universal Blue Heat/PCI RS-422/485 the RS-422/485 receivers are biased high through fixed resistors. Please refer to Figure 11 for a partial schematic.

Blue Heat/PCI User’s Manual, Connect Tech Inc.
Blue Heat/PCI RS-422/485 (6+2 model)
The Blue Heat/PCI RS-422/485 (6+2 model) offers full RS-422/485 support in hardware like the other Blue Heat/PCI RS-422/485 models. The modes include full duplex, half duplex, and multi­drop slave. The Blue Heat/PCI RS-422/485 (6+2 model) offers the following additional functionality.
Tri-state Control
The Blue Heat/PCI RS-422/485 6+2 model allows you to tri-state the line drivers on power up. To tri-state the drivers on power up please make certain there is no jumper installed across the pins on jumper block JI. Please refer to Figure 4 for the location of J1.
Line Bias/Termination
You can use jumpers J2, J3, J4, J5, J6, J7, J8, J9, J10, J11, J12, and J13 to terminate and bias TxD ±, RxD ±, RTS ±, and CTS ± on the RS-422/485 ports 7 and 8. Please refer to Figure 11 for a partial schematic of the RS-422/485 circuit for the Blue Heat/PCI RS-422/485 (6+2 model) and Figure 4 for the location of J2, J3, J4, J5, J6, J7, J8, J9, J10, J11, J12, and J13.

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

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 jumpers installed. (Please refer to Figure 7 for the locations of J1, J2, J3, J4, J5, J6, J7, and J8)

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
