Using a Serial Interface
Connecting your printer to a PC via the optional serial port involves
assembling the proper interface cabling, making the connection, and
installing the necessary PC printing software.
Before Making a Serial Connection
Before connecting the printer to the PC, you should follow the manu-
facturer’s instructions for setting up the PC and installing (if neces-
sary) any operating system software, such as DOS and/or Windows.
What You Need for a Serial Interface
Interface cables are not included with your printer. If you’re replacing
a printer, you may already have the necessary cables. If not, you’ll
need to purchase the cables from your QMS vendor or a local com-
puter store.
To connect your printer to a single PC, you need a serial cable with
either a 9- or 25-pin connector (depending on your PC’s serial port)
and a 9- or 25-pin null modem assembly to connect to the serial
cable. Depending on the type of null modem assembly you have, you
may also need a 9-to-25-pin adapter. See your cable vendor for more
specific cable assembly information.
» Note: See appendix B, the “Cable Pinouts” section in the Reference
manual for cable pinout specifications.
