  Note  All other pins of the 25 way connector are unused. 
  Note *  In the INTRAC-305 only one external input is implemented. 
As delivered this will be channel 1 (Primary Beacon). If it is 
required to use channel 2 (Secondary Beacon) input instead, 
the internal cable from connector J37 on the INTRAC 
Interface pcb to the rear panel pcb connector J3 should be 
moved to rear panel pcb connector J2. 
Communication Ports    There are three serial communication ports on the INTRAC-
305, “Remote Port”, “Test Port 1” and “Test Port 2”. The 
Remote Port is configured for RS232/RS423. Test Port 1& 
Test Port 2 can be independently configured as either RS423 
or RS422. 
    The pin allocations for both are given in the tables below.
