RS-232 (DB9) Pin Specification

The RS-232 serial port of the hub uses a 9-pin female connector. The port can be connected to a VT-100 type terminal, a PC, or a workstation emulating a VT-100 terminal. The connection can be either local, or remote through a modem. For a remote connection, a modem cable with a 9-pin male connector on the hub side is needed. The figures below show the connections necessary for local and remote connection to 9-pin and 25-pin RS-232 devices.
