13. Communications Switch
This switch selects whether the Peripheral port and RS-232C port will use
the communications settings in the PC Setup or the standard settings.
OFF The Peripheral port and RS-232C port operate according to the
communications settings in the PC Setup, except for a Programming
Console connected to the Peripheral port.
ON The Peripheral port and RS-232C port operate according to the
standard communications settings, except for Programming Consoles
connected to the Peripheral port.
Note This switch's setting has no effect on communications with a Pro-
gramming Console connected to the Peripheral port. It affects the
RS-232C port.
14. Battery
This battery backs up memory in the CPU Unit and is connected when the
Unit is shipped.
15. Expansion Connector
Connects the PC's CPU Unit to an Expansion I/O Unit or Expansion Unit
(Analog I/O Unit, Temperature Sensor Unit, or CompoBus/S I/O Link Unit).
Up to 3 Expansion Units or Expansion I/O Units can be connected to a CPU
Unit.
Note If an NT-AL001 is connected to the CPM2A's RS-232C port, only one
Expansion Unit or Expansion I/O Unit can be connected to the CPU
Unit because the NT-AL001 draws its 5-VDC power from the CPU
Unit.
