1-3, 4-6 On:
RS232 (default)
JP9 and JP15 (for COM1) / JP11 and JP17 (for COM2)
These jumpers allow you to configure the Serial COM ports to RS232, RS422 (full duplex) or
RS485. JP9, JP10 and JP15 are used to configure Serial COM port 1; JP11, JP16 and JP17 are
used to configure Serial COM port 2. The pin assignments of COM port 1 and COM port 2 will
vary according to these jumpers’ settings. You can also configure the RS485 auto flow mecha-
nism through the BIOS setup utility. For more information, please refer to Chapter 7.
Note:
When COM1 RS232/422/485 is selected, JP9 and JP15 must be set in accor-
dance to JP10. And when COM2 RS232/422/485 is selected, JP11 and JP17
must be set in accordance to JP16.
