If you did not have the twinax card installed at the factory, a field service technician
can install the field installable option (Part No. 056835) in the optional I/O board port
of your printer.

For help on cabling and communications, see the manual that comes with the twinax
adapter card.

Note: If you are using a midrange computer other than the AS/400, refer to your system
documentation for information on cabling and setting up communications.

Connecting the Printer to a Mainframe

To connect the printer directly to an IBM mainframe, you need

•

a coax adapter card.

•

a coaxial cable equivalent to IBM part number 2577672 or 1833108.

The maximum cable length allowed is 1,500 meters (4,920 feet). See the IBM
specification Installation and Assembly of Coaxial Cable and Accessories, part number
GA27-2805-4, for further information.

If you did not have the coax card installed at the factory, a field service technician can
install the field installable option (Part No. 056836) in the I/O board port of your
printer.

For help on cabling and communications, see the manual that comes with your coax
adapter card.

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 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.
