4-22 Input / Output MN1941WEN
4.5.2 Serial port
NextMove e100 provides a selectable RS232 or
RS485/422 serial port for programming, connection to
an HMI operator panel, or for communication with
other devices such as PLCs or other servo drives. The
port is fully ESD protected to IEC 1000-4-2 (15 kV).
When the NextMove e100 is connected to Mint
WorkBench, the Connectivity Wizard can be used to
configure the serial port. The configuration can also be
changed using the Mint keyword SERIALBAUD (see
the Mint help file for details). The value is restored at
power up. The port is capable of operation at up to
115.2 Kbaud.
4.5.3 Using RS232
The NextMove e100 has a full-duplex RS232 serial port with the following preset
configuration:
57.6 Kbaud
1 start bit
8 data bits
1 stop bit
No parity
Hardware handshaking lines RTS and CTS must be connected.
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 e100. The maximum recommended cable length is 3 m (10 ft) at 57.6 Kbaud (the
factory preset rate). When using lower baud rates, longer cable lengths may be used up to
maximum of 15 m (49 ft) at 9600 baud.
