158 HF680 Series User Guide
Inspect Cords and Connectors
Inspect the interface cable and connector for wear or other signs of damage. A 
badly worn cable or damaged connector may interfere with scanner operation. 
Contact your distributor for information about cable replacement. Cable 
replacement instructions are on page 158.
Replace Cables
The standard interface cable is attached to the scanner with a 10-pin modular 
connector. When properly seated, the connector is held in the scanner’s handle by 
a flexible retention tab. The interface cable is designed to be field replaceable.
• Order replacement cables from Honeywell or from an authorized distributor.
• When ordering a replacement cable, specify the cable part number of the 
original interface cable.
Replace an Interface Cable
1. Turn the power to the host system OFF.
2. Disconnect the scanner’s cable from the terminal or computer.
3. Release the cable connector:
HF680 and HF680E: 
a. Locate the small hole on the back of 
the scanner. This is the cable 
release.
b. Straighten one end of a paper clip.
c. 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.
HF680M: depress the retention tab to 
release the connector, then pull the 
connector out.
4. 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.
