IDU CONFIGURATION PORT CONNECTOR (DTE PORT)
Configuration (CONFIG) port connections to modems, computers, or terminals, as well as auxiliary data
connections, are made using a 9-pin, D-type, female connector, compliant to EIA-574 wiring. The CONFIG port
is configured as a DTE (Data Terminal Equipment) so a null modem cable (pin 2 is connected to pin 3) is
required when connecting to a DTE such as a standard PC Serial COM port.
