  • Page 9: Functional Description

    Functional Description A pair of 9971-C interface cards provide transmission for one 10 Base T Ethernet link and two independent 115 Kbps data channels via the duplex high-speed ports available on selected video or data over fiber transmission cards. Currently, the 9971-C will operate with the 9252DT/DR, the 9421DT/DR, and the 9672 cards. The cards operate on 6VDC as supplied by the chassis into which it is installed.

  • Page 12: Set Up And Operation Of The 9971-C

    Set Up and Operation of the 9971-C Set up and operation of the 9971-C cards consists of setting the data port switches, installing the unit into a Series 9000 chassis, connecting the provided Cat5 jumper cable from the high-speed port on the optical communications card to the 9971-C.
  • Page 13 Limitations for Half Duplex When an Ethernet link operates in the half duplex mode, there are limitations imposed on the end-to-end length of the system. Operating on fiber does not change these limitations and the user should be aware that, in general, the collision domain limits the total network diameter to 4000 meters or less, including fiber runs.
  • Page 14 Option Module Type B — Duplex Data Compared to the first and interim versions, the latest version has an additional bias switch to set for more robust RS485 operation of the data module. The bias resistors keep the differential signal pair biased so that when it is in a High-Z state the line receivers interpret the line as being inactive (no data transmitted).

  • Page 16 RS422 Option Module B supports both 2-wire (simplex) and 4-wire (duplex) RS422 communications. RS422 is a differential communications scheme and uses the polarity difference between the + and – leads to transmit the data bits. The signals input on pins 1 and 2 at one end of the link are transmitted to the other end of the link and are output on pins 3 and 4.

  • Page 19 RS485 is a “many-to-many” type system, permitting up to 32 devices or receivers to be electrically connected to one transmitter. Refer to the “Termination Rules for RS422, RS485, and Manchester” later in this section for more details on terminations to ensure you have terminated multiple connections correctly. The fiber connection isolates parts of a system, effectively creating more than one electrical buss.

  • Page 21 wire system. In normal operation of RS485 systems, the + (plus) terminals should be biased positive and the – (minus) terminals should be biased to signal ground. To determine if the bias resistors need to be enabled, make the following voltage measurements between the + (plus) signal line and the – (minus) signal line. Make the measurements with no data transmissions occurring.
