Scanner Scale Pinout Connections

There are four additional 10-pin modular jacks located on the bottom of the of the MS2420/MS2430 scanner models that may be used for an integrated scale application and the use of a remote display.

Note: Please keep in mind that every application is unique. The use of these connections depends on the specifications of the scale’s manufacturer. The following pinouts are for reference only. If the scanner has been integrated with a scale, refer to the Scale Addendum for detailed instructions on the appropriate cable connections, communication specifications and calibration procedures required by the scale manufacturer and local Weights and Measures authorities.

When connecting any combination of scale/external scale display to the MS2420/MS2430 do not exceed the following current restrictions: 12V @ 0.7A max. / 5V @ 0.2A max.
