Installation Procedures
1. Install in-house wiring between the locations desired for the
terminal and the printer. The ends of the cable should be within 3
meters (10 feet) of the devices for the drop cables to reach.
Note: Use CAT 1 two-twisted pair 24 AWG communications cable
or equivalent.
2. Connect a serial modem to each end of the in-house wiring,
connecting RCV+ and RCV- on one end, and XMT+ and XMT- on
the other end, respectively, using one twisted pair for RCV and
another twisted pair for XMT.
3. For the printers, connect one end of the 497-0411815 drop cable to a
9-pin RS-232 port on the terminal. Connect the other end to the
serial modem via the 25-pin āDā shell connector, securing it with
the thumbscrews.
