Connecting the Printer to a Mainframe

To connect the printer directly to an IBM mainframe, you need
•
a coax/twinax interface adapter (P/N 063870).
•
a coaxial cable equivalent to IBM P/N 2577672 or 1833108.
The maximum cable length allowed is 4920 feet (1500 meters). See the IBM
specification Installation and Assembly of Coaxial Cable and Accessories, part
number GA27-2805-4, for further information.
If the coax/twinax interface adapter was not installed in the printer at the
factory, you can have the field installable option (P/N 063870) installed in your
printer. Refer to the manual that comes with the interface adapter for more
information on cabling and communications.

Cabling in Noisy Electrical Environments

The items listed below create noisy electrical environments that can disrupt
data communications between your host computer and the printer:
•
Large power transformers
•
Large electrical motors
•
Arc welders
•
Motor controllers
•
Switch gears
If any of these items are near your printer, you may want to try any of the
following suggestions to reduce the effects of electrical noise. If you need help
eliminating noise, ask your Intermec representative for assistance.
•
Always use shielded cable. Connect the cable and shield to the metal
backshells on the cable connectors and fasten the connectors to the serial
ports using screws.
•
Install ferrite cable clamps.
•
Connect the printer chassis ground to the building ground. You will find
the chassis ground on the ground pin of the printer power cord.
