PERATION
The MS4980 supports two standard modes of operation for scanning bar codes,
automatic activation and manual activation scanning. Scanning while in the
automatic activation mode can occur in either one of two configurable options,
pass-through or presentation. Both the pass-through and the presentation
options are enabled by default.
With the default configuration, the scanner
operates in the pass-through state for 300 ms and then changes to the
presentation state for additional decoding capability.
The different modes of operation and scanner states are as follows:
Automatic Activation Mode
Pass-through Scanning
• Decodes ONLY 1D and PDF bar codes
• Scanning
Method:
1. Pass the bar code through the active scan area to scan, decode
and send data
Presentation Scanning
• Decodes ALL 1D, PDF and 2D matrix codes
• Scanning
Method:
1. Place the object in the IR activation range
2. Hold the object’s bar code in front of the scan window within the
active scan area to scan, decode and send data
The MS4980 requires a stand-alone 5V power supply for pass-through capabilities to
function.
Default configuration recommended for optimum scan performance.
