SCANNER AND CABLE TERMINATIONS
SCALE READY MS2321 MODELS – ADDITIONAL PINOUT CONNECTIONS
There are four additional 10-pin modular jacks located on the bottom of the of the MS2321 StratosH models that may be used for an
integrated scale application and the use of a remote display. When using the RS232/Full Speed USB/RS485 (-121) interface, the USB
and RS485 interfaces are not active at the same time.
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 M2321 do not exceed the following
current restrictions: 12V @ 0.2A max. / 5V @ 0.3A max.
