Description
RS232 connections on a single 9-pin male D-type connector
The NextMove BX
II
has a full-duplex RS232 serial port with the following preset configuration:
H 9600 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 Mint keyword SERIALBAUD.Itisstoredin
EEPROM and restored at power up.
The port is configured as a DTE (Data Terminal Equipment) unit so it is possible to operate the
controller with any DCE (Data Communications Equipment) or DTE equipment. Full duplex
transmission with hardware handshaking is supported.
Only the TXD, RXD and 0V GND connections are essential for communication, although
hardware handshaking will not be supported unless the other connections are made.
Both the output and input circuitry are single ended and operate between ±12V. The port is
capable of operation at up to 57.6Kbaud.
