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:
