2 optically isolated serial ports standard, labeled SERIAL 1 supporting full handshaking and SERIAL 2.
The RS-232 D-connector is a panel mount, 9-pin female type, wired in a Data Terminal Equipment (DTE) configura-
tion. For example, any RS-232 port in any TLS consoles is also a DTE, therefore, a Null Cable is needed in order for
communication to happen between the two consoles.
A Data Communication Equipment (DCE) device such as a modem may be connected directly to the interface using
a straight-through cable (modem support may not be available on all ATGs). Handshake signals in the system are
configurable.
RS-232 signals are wired to the female D-connectors as follows:
