Communications Ports

2
NOTE: The panel has one built-in RJ12 serial communications port (Port1 - RS-232) and one 15-pin serial
communications port (Port2 - RS-232/422/485). Only one of the ports can be used with a connected PLC.
The programming software allows the user to select either Comm. Port1 or Comm. Port2 under the Panel
Manager dialog box. When using Port2 to communicate with the connected PLC, Port1 can still be used with
the EA-MG-PGM-CBL Software Programming Cable Assembly to transfer projects between the PC and panel.
