			Description	RS232 connections on a 9-pin male D-type connector

This connector is used to connect the NextMove ST to the PC running WorkBench v5, or other controller. It is a full-duplex RS232 serial port with the following preset configuration:

H57,600 baud

H1 start bit

H8 data bits

H1 stop bit

HNo parity

HHardware handshaking lines (RS232) RTS and CTS must be connected.

The configuration can be changed using the SERIALBAUD keyword. It is stored in EEPROM and restored at power up. The port is capable of operation at up to 115,200 baud.

The port is configured as a DCE (Data Communications Equipment) unit so it is possible to operate the controller with any DCE or DTE (Data Terminal Equipment). Full duplex transmission with hardware handshaking is supported.

Only the TXD, RXD and 0V GND connections are required for communication. Pins 4 and 6 are linked on the NextMove ST.
