PRINTER CABLES

Warning: Connection of a serial 400 to a parallel port may result in damage to the printer
and/or computer. Connection of a 400 with a parallel board to a serial port may result in
damage to the printer and/or computer.
The printer cables needed for the 400 printer are standard and available through Microcom
Corporation. You will not need a NULL-modem cable because the printer is DCE equipment.
For parallel connection, use a straight 25 pin male to 25 pin male cable, connected from the
desired parallel port of the host computer to the 25 pin connector on the optional 400 parallel
board.
For serial connection, (standard on the 400) if your host computer has a...
25 pin serial com port - Use a standard 25 pin male to 9 pin male serial cable.
9 pin serial com port - Use a 9 pin female to 9 pin male extension cable.
Note: NULL modem cable adapters are not necessary since the printer is DCE equipment.
