RS-232 adapter
The RS-232 Adapter (GE Item No. 520-0207LF) is a standard RS-232 serial I/O adapter card
that plugs into any serial communication slot (slots 1 through 8) on the D400. It contains
two independently isolated RS-232 serial ports (Port 1 J3 and Port 2 J2) each with a DB-9
connector with common shields.
See “RS-232 connections” on page 53 for typical cable connections and connector pin
outs.
Configuration options
The RS-232 card supports the following configuration options on each port:
DCE (Data Communications Equipment)
DTE (Data Terminal Equipment)
+5 V (320 mA) output
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:
Factory default
The factory default setting is DTE on each port.
