* Pins a16 and a17 are linked on the NextMove ES.
The serial connector duplicates the signals present on the 96-pin connector. It is used to connect
the NextMove ES to the PC running Mint WorkBench, or other controller. If an optional Baldor
backplane is being used, its serial connector (section 5.2.14 or 5.3.14) will carry the same signals.
Do not attempt to use more than one set of serial connections at the same time.
NextMove ES is available with either an RS232 or RS485 serial port (see section 2.2.1). The port
is fully ESD protected to IEC 1000-4-2 (15 kV). When the NextMove ES is connected to Mint
WorkBench, the Tools, Options menu item 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). It is stored in EEPROM and restored at power up. The port is capable of operation at
up to 115.2 Kbaud on RS232.
4.5.5 Using RS232

H
57.6 Kbaud
H
1 start bit
H
8 data bits
H
1 stop bit
H
No parity
H
Hardware handshaking lines (RS232) RTS and CTS must be connected.
