You will need two modems and two available phone lines, one for your PC and
one for your 9400. Orban Customer Service supports only the 3Com / U.S. Robotics®
56kbps fax modem EXT on the 9400 side of your connection, although other
56kbps modems will usually work OK.
You can use either an internal or an external modem with your PC.
A) Connect the telephone line from the wall phone jack to the wall connection
icon on the back of the modem (modem in).
B) Connect the modem to the 9400’s serial port with a standard (not null) modem
cable.
The cable provided with your 9400 is a null modem cable and will not
work.
C) Set the modem to AUTO ANSWER and turn it on.
For 3Com / U.S. Robotics® 56kbps fax modem EXT, set dipswitches 3, 5,
and 8 in the down position to activate the AUTO ANSWER setting. All other
dipswitches should be set to the up position.
