NextMove e 100 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 Baldor servo drives. The
port is fully ESD protected to IEC 1000-4-2 (15 kV). When
the NextMove
e 100 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 e 100 has a full-duplex RS232 serial port with the following preset configuration:
H
57.6 Kbaud
H
1 start bit
H
8 data bits
H
1 stop bit
H
No parity
H
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
e 100. 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.
