9
Connector X6 is a 9-pin male D-type connector. This port is configurable as either RS232 or
4-wire RS422 / RS485, using front panel DIP switch number 10 (see section 3.9.7). The Mint
keyword SERIALBAUD is used to configure the port and is explained in the Mint help file. See
also sections 4.4.4 and 4.4.5. The port is fully ESD protected to IEC 1000-4-2 (15kV).
When using RS485 / RS422 mode, front panel DIP switch number 6 may be used to connect
an internal 120Ω termination resistor between the RX+ and RX- signals. Switch 6 should
remain in the Off position when using RS232.
CAUTION: Pin 9 is used to carry +8V for powering certain Baldor keypad peripherals.
