The RS232 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, but since many devices will check the RTS and CTS lines, these must also be connected. Pins 4 and 6 are linked on the NextMove ES.
The maximum recommended cable length is 3m (10ft) at 57.6 Kbaud. When using lower baud rates, longer cable lengths may be used up to maximum of 15m (49ft) at 9600 baud. A suitable cable is available from Baldor, catalog number
