RS-422A Interface Voltage Levels
The interface signal voltage levels conform with the EIA RS-422A
standard. The differential voltage varies from 200 mV to 6 V.
SERIAL Connector
The connector marked “
IOIOI
” (RS-232C/RS-422A) on the rear panel is a
DB-25S connector. Use a DB-25P connector (or equivalent) for the
connector on the cable.
