Autogating. Multitasking operating systems, like Windows 95, Windows NT, OS/2 and UNIX, cannot successfully use the RTS line to control the gating of the PC’s transmitter. Whilst they can set the RTS line true just before the data transmission starts, they cannot set the RTS line false quickly enough after the data has gone. -

37 Way D Connector Configuring the Card. PCI cards require no hardware configuration for IRQ and address allocation - this is done automatically at start up by the PC. However, the PCI quad opto RS422/485 has four sets of jumpers for configuration of RS485 multiplex modes for each port, how to configure these jumpers is shown below. - Page 12 Where: TX/RX1+ and TX/RX1- control port 1 RS485 multiplexing. TX/RX2+ and TX/RX2- control port 2 RS485 multiplexing. TX/RX3+ and TX/RX3- control port 3 RS485 multiplexing. TX/RX4+ and TX/RX4- control port 4 RS485 multiplexing. Full Duplex Settings(port 1).

Page 52: Chapter 10 Optional Rs422/485 Operation
Chapter 10 Optional RS422/485 Operation The RS422 Standard. The RS422 standard defines a serial communications standard. RS422 is a high speed and/or long distance data transmission. Each signal is carried by a pair of wires and is thus a differential data transmission system. Over distances up to 40 feet the maximum data rate is 10 Megabits per second, and for distances up to 4000 feet the maximum data rate is 100 Kilobytes per second. -

RS422 and RS485 lines should be terminated at the end of the main branch of the RECEIVER, in the cables characteristic impedance. These terminating impedance’s stop echoes caused by the serial data being reflected back at the cable ends. It is not necessary to terminate the transmitter end of the twisted pair. -

Page 55: Rs485 Cable
For best noise immunity use twisted pair cables to make the RS485 connection. In Half Duplex wiring only 1 twisted cable pair is needed. Two twisted pair cables are needed for Full Duplex communications. Use screened twisted pair Belden cable 9729 and 9829, UL type 2493 and 2919 or IBM Part No 4716748 cable to make the RS485 connection. -
