Blue Heat/PCI User’s Manual, Connect Tech Inc. 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 board under certain operating systems.
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.
Blue Heat/PCI User’s Manual, Connect Tech Inc. Software Installation Introduction Blue Heat/PCI boards are standard multi-port serial adapters that utilize 16C654, 16C864 or 16C2850 UARTS. In many cases, users have software that will interface directly to the Blue Heat/PCI boards. Many operating systems come with handlers to control access to multiple 8250 style UARTS.

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.
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.

Blue Heat/PCI User’s Manual, Connect Tech Inc. 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.
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 +.
Blue Heat/PCI User’s Manual, Connect Tech Inc. Line/Bias Termination You can use jumper blocks JA, JB, JC and JD to terminate and bias TxD ±, RxD ±, RTS ±, and CTS ± on the individual RS-422/485 ports through jumper selectable 150 Ω fixed resistors. Please refer to Figure 12 for a partial schematic of the RS-422/485 circuit for the Blue Heat/PCI Opto and Figure 6 for the locations of JA, JB, JC, and JD.
Blue Heat/PCI User’s Manual, Connect Tech Inc. RS-422/485 Cable Wiring You can wire Blue Heat/PCI RS-422/485, Opto RS-422/485 and Universal Blue Heat/PCI RS-422/485 adapters in various ways to communicate with RS-422/485 peripherals. This section describes a few examples of RS-422/485 cabling schemes. Figure 13 below describes a 4 wire cabling scheme between a port on the Blue Heat/PCI RS-422/485, Opto, Opto RS-422/485 or Universal Blue Heat/PCI RS-422/485 adapter to a port on the RS-422/485 peripheral.

Blue Heat/PCI User’s Manual, Connect Tech Inc. 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.
Blue Heat/PCI User’s Manual, Connect Tech Inc. Current Source/Voltage Selection When using the current source in a loop with low resistance, the transistor will run hot. This can be avoided by increasing the loop resistance. The calculation for Maximum Loop Resistance(RL ) is: Max RL = VS - (S × VD ) 0.
Blue Heat/PCI User’s Manual, Connect Tech Inc. Current Loop Cable Wiring You can wire Blue Heat/PCI CL adapters in various ways to communicate with 20mA Current Loop peripherals. A few examples of Current Loop cabling schemes follow. Figure 16 below depicts a 4 wire cabling scheme between a port on the Blue Heat/PCI CL adapter to another port on the Blue Heat/PCI CL adapter.
