4.5.7 Connecting serial Baldor HMI Operator Panels

Serial Baldor HMI Operator Panels use a 15-pin male D-type connector (marked PLC PORT), but the NextMove ES Serial connector uses a 9-pin male D-type connector. The NextMove ES may be connected with or without hardware handshaking, as shown in Figure 17:

Baldor HMI		NextMove ES
PLC PORT		Serial Port
		7	RTS
	Twisted pair	8	CTS
RXD 2		3	TXD
TXD 3		2	RXD
GND 5		5	GND
1

Without hardware handshaking

Alternatively, the Baldor HMI panel may be connected using RS485/422, as shown in Figure 18:
