Reason: Expand, find out more about cable IDs, make table |
IBM Serial Cables have certain (ID) pins connected to the common ground connection pin to have the machine know what cable type is attached.
Modern PCI machines have a Mini-Centronics style connector for their serial ports, while the older, SPD based machines have D-Shell connectors. Both connectors on the machine check for the Cable-ID.
To identify a V.24, RS-232 "Modem" Cable to either a #2651 (single port), or #2609 (dual port) serial I/O-Adapter, Pins 1 and 13 need to be connected to Pin 7 (Ground) on the DB-25P connector on the machine (DCE) side. Pins 1 and 13 on the remote (DTE) side are not to be connected anywhere.
