3. Installation
3.1 General
CAUTION
Make sure the computer and any other connected devices
are turned off before you make any connections to the
Converter.
The Converter has been designed to plug directly
into a computer’s DB25 male (DTE) serial port, or
into a computer’s DB25 female parallel-printer port.
If your serial port is a DB9 male port, use an ordinary
DB9-female-to-DB25-male adapter. If you’re out-
putting to a parallel printer, use a standard PC-to-
parallel-printer cable and a DB25 female-to-female
gender changer (ordered separately, part number
FA412).
