KIT-400 – Connecting KIT-400
Connecting an Occupancy Sensor to the TOGL Pin
The KIT-400R TOGL pin function is defined via the KIT-400R OSD menu (see Defining
the TOGGLE PIN on KIT-400R on page 22). By default, the display toggles on or off when
momentarily connected. By setting the Toggle function, you can set the pin for level-triggering
rather than edge-triggering (i.e., constant contact connection rather than momentary
connection), allowing, for example, connection to an occupancy sensor that triggers the
toggle commands.
Instead of a push-to-make switch, TOGGLE may be configured to operate with a standard
SPST switch or for TTL level detection (for example, to use with an occupancy sensor).
You can use an occupancy sensor to turn on the display and auto sync off to turn it off once it
is not used, as described in the following example:
• An occupancy sensor is connected to the TOGL pin.
• The TOGL pin is set to ON (see Defining the TOGGLE PIN on KIT-400R on page 22) so
that the display is turned on when the occupancy sensor detects the presence of people
in the room. (Set the sensor to short the TOGL pin to ground upon detecting occupancy).
• Auto SYNC OFF is set to Enable (see Setting Sleep Mode on page 20) so that when the
room is no longer in use, the display turns off 2 minutes after an input signal is no longer
detected.
You can also set the TOGL pin to OFF so that when the sensor detects no people in the room
the display turns off. (Set the sensor to short the TOGL pin to ground when occupancy is not
detected).
Wiring RJ-45 Connectors
This section defines the TP pinout, using a straight pin-to-pin cable with RJ-45 connectors.
For HDBT cables, it is recommended that the cable ground shielding be connected/soldered
to the connector shield.
