See "RS-232 connections" on page 58 for typical cable connections and connector pin
outs.
The RS-232 card supports the following configuration options on each port:
• DCE (Data Communications Equipment), if SW1/SW2 pin 1 is set to A
• DTE (Data Terminal Equipment), if SW1/SW2 pin 1 is set to A
• +5V (320mA) output on pin 1 of rear DB9 connector if. SW1/SW2 position 1 is OFF and
position 2 is set to ON.
Refer to module layout drawing 520-0207-ML for details.
In addition, the RS-232 card is configurable to optionally provide an IRIG-B signal (on pin 4)
and individually isolated Ground (on pin 6).
The signal type and pin options for each port are selectable via two sets of switches on the
RS-232 card:
• Port 2 (J2) is configured by switches SW1 and SW3
• Port 1 (J3) is configured by switches SW2 and SW4
Follow instructions for setting the switches to select the appropriate functions for each
port.
The signal format outputted to the RS-232 cards is dependent upon the format applied to
the IRIG-B input adapter:
IRIG-B Input Format...
Pulse Width Modulated (B0xx)
Manchester (B2xx)
AM Modulated (B1xx)
The factory default setting is DTE on each port.
