Introduction
The Blue Heat/PCI family of adapters includes the Blue Heat/PCI RS-232, RS-422/485, RJ-11,
Opto, 20mA CL and Universal Blue Heat/PCI RS-422/485. provide high speed interfaces,
allowing you to connect up to eight serial devices through one expansion slot.
Your Blue Heat/PCI product consists of the following components:
● One Blue Heat/PCI adapter
● One cable harness or external connector box (four and eight port models only)
● One CD containing device drivers and documentation
Blue Heat/PCI RS-422/485, RJ-11, Opto, Opto RS-422/485, 20mA CL and Universal Blue
Heat/PCI RS-422/485 adapters provide high speed interfaces between a host computer’s PCI bus
and multiple external serial devices.

Features

● 2, 4, or 8 asynchronous serial ports
● Multiple interface options:
RS-232 (Blue Heat/PCI and RJ-11 adapters)
RS-232 and/or RS-422/485 (Blue Heat/PCI RS-422/485, Opto, Opto RS-422/485
and Universal Blue Heat/PCI RS-422/485 adapters)
20mA Current Loop interface (Blue Heat/PCI CL adapters)
● The Blue Heat/PCI RS-422/485, Opto, Opto RS-422/485, Universal Blue Heat/PCI
RS-422/485 offer full RS-422/485 support in hardware. The modes are as follows:
Full Duplex Mode
Half Duplex Mode
Multi-drop Slave Mode
● Different models of Blue Heat/PCI, RS-422/485, RJ-11, 20mA CL, Opto, Opto RS-422/485
and Universal Blue Heat/PCI RS-422/485 adapters may reside in a host computer offering
up to 32 ports per system
● 16C654 quad UARTs control two, four or eight ports (Blue Heat/PCI, RJ-11, 20mA CL
models)
● 16C864 quad UARTs control two, four or eight ports (Blue Heat/PCI RS-422/485,
Universal Blue Heat/PCI RS-422/485 models)
● 16C2850 dual UARTs control two, or four ports (Blue Heat/PCI Opto, /PCI Opto
RS-422/485)
● Each port on a Blue Heat/PCI and RJ-11 models offers independent baud rate selection from
21 bps to 1382.4 Kbps, with 5, 6, 7 or 8 data bits and 1, 1.5, 2 stop bits, odd, even, mark and
space parity
● Each port on a Blue Heat/PCI RS-422/485, Opto, Opto RS-422/485 and Universal Blue
Heat/PCI RS-422/485 adapter offers independent baud rate selection from 50 bps to 921.6
Kbps, with 5, 6, 7 or 8 data bits and 1, 1.5, 2 stop bits, odd, even, mark and space parity
● Each port on a Blue Heat/PCI 20mA CL adapter offers independent baud rate selection from
21 bps to 57.6 Kbps, with 5, 6, 7 or 8 data bits and 1, 1.5, 2 stop bits, odd, even, mark and
space parity
● Blue Heat/PCI, Blue Heat/PCI RS-422/485 and Universal Blue Heat/PCI RS-422/485
adapters come with optional Transient Voltage Protection (surge suppression – IEC 1000-4
compatible) on every signal line of every port
● Each port is independently optically isolated to 1K or 3.0kV AC peak to peak (Blue
Heat/PCI Opto models)
● The RS-232 line drivers on the first three (3) ports offer double the drive capability of
standard RS-232 line drivers (Blue Heat/PCI and RJ-11 models)
