outputs on the male DCE connector. Pins 3 (Receive Data), 5
(Clear To Send), 6 (Data Set Ready), and 8 (Carrier Detect)
are normally outputs from a DCE port, so they are connected
directly from the male to all female connectors. Can be left
permanently installed.
Robert M. Paratore, Director of Engineering
To ensure proper operation, lines 2, 4, and 20 on the
unused female inputs should be low or open to allow the other inputs to operate properly. Pins 1 and 7 are connected
to provide a ground path. Pin 1 is Protective Ground and Pin 7 is Signal Ground on all three DB25 connectors.
To install the 232MDS3, connect a "straight through" cable (Pin 1 to Pin 1, Pin 2 to Pin 2, etc.) between the
MDS and the modem. Any pin reversing or jumpering should be done on the cables that connect to the computers or
terminals.
