6.4 Transmitting Commands via the Contact Closure and
Relays
You can use your FC-5 to transmit commands via the contact closure to the
relays, and to a projector via RS-232:
Figure 17: Transmitting Commands via the Contact closure and Relays
The INPUTS contact closure remote control pins let you switch commands to the relays,
and via RS-232. Relay 1 is connected to the blinds, and relay 2 is connected to the
lighting system (see
Section 6.3 for the Relay PINOUT). INPUT contact closure remote
control pins 1 to 4 are connected to switches 1 to 4, respectively.
In this particular example, pressing:
• Switch button 1 turns on the projector
• Switch button 2 turns off the projector
• Switch button 3 toggles the blinds up/down
• Switch button 4 toggles the lights on/off
