1.3.3.2 SETUP AND COM PORTS
The SETUP and COM serial connections are DE-9F RS-232 ports. Refer to Table 3 for pin out descriptions and Section 4.3.4
for control line configuration of DCD, DTR, RTS and CTS control lines.
Serial port considerations:
 Viper SETUP and COM ports are Data Communication Equipment (DCE) devices
 In general, equipment connected to the Viper SC’s serial ports is Data Terminal Equipment (DTE) and a straight-
through cable is recommended.
 If a DCE device is connected to the Viper serial ports, a null modem cable/adapter is required.
