SCALE READY MS2221 MODELS – ADDITIONAL PINOUT CONNECTIONS
There are four additional 10-pin modular jacks located on the bottom of the of the MS2221 StratosS models that may be used
for an integrated scale application and the use of a remote display.
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 M2221 do not exceed the
following current restrictions: 12V @ 0.7A max. / 5V @ 0.2A max.
