C.5.1 Serial Port Setting
The serial interfaces CON3 (COM1) and CON2 (COM2) on the IDE2 module may be
configured for either RS232, RS422 or RS485 by setting solder jumpers.
The default configuration is RS232
RS422 and RS485 COM1 Termination
When the IDE2 module is using the onboard RS485 interface and is the last on the
RS422 or RS485 bus, then the RS422 or RS485 interface must provide termination
resistance. The purpose of jumpers J8 and J9 are to enable this line termination resistor
(120 R).
