1.3.4 SETUP and COM Ports
The SETUP and COM serial connections are DE-9F RS-232 ports.
Serial port considerations:
• ViPR radio modem SETUP and COM ports are Data Communication Equipment (DCE)
devices
• In general, equipment connected to the ViPR’s SETUP / COM serial port is Data
Terminal Equipment (DTE) and a straight-through cable is recommended.
Note: If a DCE device is connected to the ViPR SETUP / COM port, a null modem
cable/adapter is required.
The pin-out for the SETUP and COM ports are shown in Table 1.3.
