Connecting the Omni 288P Turn off the power on the computer (if possible) and the modem before making connections. Then connect the modem according to the rear panel labels. Power connection Use only the ZyXEL power adapter that is supplied with this modem. Using any other power adapter may cause serious damage to the modem and void warranty. Connect the power cord from the power adapter to an AC electrical outlet and connect the round power plug from the adapter to the power jack on the modem. This completes the power connection for the Omni 288P. Warning: Always turn off the power switch on the modem before connecting the power adapter to the modem. Avoid plugging or unplugging the modem's power jack with the power switch turned on as this may damage the modem. Computer and Printer Connection The modem has a parallel port. You can connect this parallel port connector (labeled TO DTE) to your PC's bidirectional parallel port for DTE communication. A normal 25-wire male to female shielded RS-232 cable can be used for this connection. You can also connect the modem's parallel port to a laser printer for direct fax reception and printing operation. A normal PC printer cable together with a female DB25 to female DB25 gender changer can be used for this connection. 3-12
