Replacing the Interface Cable
The standard interface cable is attached to the scanner with an 10-pin modular
connector. When properly seated, the connector is held in the IT3800 scanner’s
handle by a flexible retention tab. The IT3900 connector is located in the pod at
the end of the IT3900 cable. The interface cable is designed to be field
replaceable.
• •Order replacement cables from Hand Held Products or from an authorized
distributor.
• •When ordering a replacement cable, specify the cable part number of the
original interface cable.
To Replace the Interface Cable:
1. Turn the power to the host system
OFF.
2. Disconnect the scanner’s cable from
the terminal or computer.
3. Locate the small hole on the side of
the scanner’s handle (IT3800), or on
the underside of the connector pod
(IT3900). This is the cable release.
4. Straighten one end of a paper clip.
5. Insert the end of the paper clip into the
small hole and press in. This
depresses the retention tab, releasing
the connector. Pull the connector out
while maintaining pressure on the
paper clip, then remove the paper clip.
6. Replace with the new cable.
Insert the connector into the opening
and press firmly. The connector is
keyed to go in only one way, and will
click into place.
