Connecting the Printer to a Mainframe
To connect the printer directly to an IBM mainframe, you need:
•
a coax adapter card (Part No. 067880).
•
a coax cable equivalent to IBM part number 2577672 or 1833108.
If you did not order the coax card to be installed at the factory, contact your local
Intermec representative to have one installed in the optional I/O board port of the
printer.
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.
For help on cabling and communications, see the manual that comes with the 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 the 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.
