Description
The Remote Keyswitch and RS-232 Port Assembly consists of a Mode
Select Keyswitch and an RS-232 port installed in a housing. This assembly
can be mounted in a location that provides easier access than the keyswitch
and port on the rear of the PanelView terminal.
The assembly is attached to a 10 foot (3 m) cable that connects to the
RS-232 serial interface port on the rear of the PanelView terminal. It must
be mounted with the attached gasket, washers, and screw-on cap. The cap
must be fastened to one of the mounting screws with the chain provided.
When not in use, the cap protects the assembly to maintain a NEMA 4X
rating (indoor use only).

2. Install the assembly in the cutout, from the rear of the panel.
3. Use the washers provided between the screw heads and the front side of
the panel. The narrow end of the washer is oriented towards the head of
the screw, as illustrated in Figure 1.
4. Fasten the housing to the panel door with the four mounting screws
provided. To maintain a good seal, torque the screws down to between 9
and 12 inch-pounds.
5. Before installing the lower left mounting screw, thread the screw
through the end of the restraining chain attached to the cap. Then install
the screw in the housing.
6. Connect the RS-232 connector on the assembly to the RS-232 serial
interface port on the rear of the PanelView terminal (Figure 4). Attach it
with the mounting screws on the connector housing.
