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 computer store.
To connect your printer to a single computer, you need a serial cable with either a 9- or
25-pin connector (depending on your computer’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 appendix B, “Tech-
nical Specifications,” in the
Reference
guide for cable pin-outs or your cable vendor for
more specific cable assembly information.
