Coax/Twinax Interface Card Service Technician
Instructions
The coax/twinax interface card is an internal interface card for Intermec 3XXX, 44XX,
501XP, and 601XP printers. This instruction explains how to install the interface and
how to set the DIP switches and jumper. This instruction sheet has seven sections:
Preparing a 3XXX or 44XX Printer This section explains how to open the 3XXX and
44XX printers.
Preparing a 501XP or 601XP Printer This section explains how to open the 501XP
and 601XP printers.
Installing the Coax/Twinax Interface Card This section explains how to install the
interface card and connect it to the PCB of the 3XXX, 44XX, 501XP, or 601XP
printer.
Testing the Interface Card This section explains how to test to make sure the interface
card is communicating with the printer and host.
Jumper and DIP Switch Settings This section describes the different jumper and DIP
switch settings.
Making the Coax/Twinax Interface Card Backward-Compatible This section explains
how to set the jumper and DIP switches if you are replacing an old twinax card (Part
No. 057029-004) or an old coax card (Part No. 057026-004).
Setting the Coax/Twinax Interface Card to Use IBM Latin 1 This section explains how
to set the jumper and DIP switches to use IBM Latin 1.
Note: The illustrations for the 3XXX and 44XX printers show a 4420 and the
illustrations for the 501XP and 601XP printers show a 501XP.
You will need the following to install the interface card:
• One of the following field installation kits:
• Twinax kit for the 3XXX and 44XX printers, Part No. 067879
• Twinax kit for the 501XP and 601XP printers, Part No. 067881
• Coax kit for the 3XXX and 44XX printers, Part No. 067880
• Coax kit for the 501XP and 601XP printers, Part No. 067882
• A Phillips screwdriver (3XXX and 44XX printers)
• A torx wrench (501XP and 601XP printers)

Installing the Coax/Twinax Interface Card
1. Remove the plate covering the coax/twinax interface card expansion slot on the
back panel of the printer.
2. Set the DIP switches and jumpers for the card. For help, see “Jumper and DIP
Switch Settings” later in this instruction sheet.
3. Mount the coax/twinax interface card to the inside back panel of the printer.
4. For the 501XP or 601XP printer, remove and disconnect the current parallel card if
one is installed.
5. Attach the coax/twinax connector to the parallel port (J3 port or P31 port).
6. Reinstall the PCB and media covers.
7. Attach the coax or twinax adapter cable to the 9-pin connector on the interface
card.
