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:
H 57,600 baud
H 1startbit
H 8 data bits
H 1stopbit
H No parity
H Hardware 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.
