JetBox 8210 supports four serial ports. The first 2 ports, COM1 and COM2, are

RS232/422/485 configurable. The later 2 ports are dedicated for RS232 mode. Refer

with 3-3-2 VGA Connector for connector pin assignments.

JetBox 8210 configures COM1 and COM2 as RS232 operation mode as factory default

settings. These operation mode settings are stored in the system EEPROM, not

registry, and the settings are applied during system boot up. One configuring utility

named "SerCon" located in the control panel could be used to change the settings

and save to the system EEPROM.

Replace the CF card "B" of JetBox 8210 "B" with from a well configured CF card "A" of

JetBox 8210 "A" will not change the serial port configurations of JetBox 8210 "B". It's

suggested to configure the serial ports programmatically if a great quantity of JetBox

8210 is applied.
