The JetBox 8210 provides 2 D-sub 9-pin connectors for RS-232/422/485
communications. The default setting of COM1~ COM2 is RS-232. Please refer with the
programming guide for changing the settings or use the “SerCon” control applet of

COM3 and COM4 Connectors
The JetBox 8210 provides 2 D-sub 9-pin connectors (COM3 and COM4) for RS-232
communication.
Note the settings are stored in the EEPROM, not registry. It’s necessary to configure
each hardware target manually or programmatically. Replacing the CF card with OS
and hive registry data will not affect the mode settings of the COM ports.
