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.
Configuring the Serial Port for Communications
You need to configure the serial port of the printer to match the
configuration of your PC or network controlling device. If the printer’s
default settings do not match, use the DIP switch settings table to
configure the serial port.
Note:
You need to configure the printer serial port for 8 data bits if you
want to print code pages or 8-bit ASCII character sets. Also, use
XON/XOFF protocol for Ready/Busy buffer control.
To configure the printer serial port
1
Use the following DIP Switch Settings Descriptions table to locate the
DIP switches you use to configure the serial port.
2
Use a small straight-slot screwdriver to set the appropriate DIP switches.
For example, if you want to change the media type to thermal transfer,
set DIP switch 8 on the bottom bank of switches to the on position.
3
Turn the printer power off and then on for the configuration changes to
take effect.
Note:
Make sure you set all Multi-Drop switches to off if you are not
using a Multi-Drop network.
