Extron electronic 68-388-01 manual Comm Connector and Infrared Emitter, Room/Relay Connector

Making Connections • Chapter 2

3.5 mm, 5-pole captive screw connectors are used for the audio inputs and one output, as well as for accessories. These include:

•Aux1 & Aux2 – SCP 100 remote panels (2 optional)

•Relay – Room/relay custom control (standard feature)

•Comm – projector control through the standard IR Emitter or the optional IR Broadcaster.

One three-contact stereo phono-type of connector is provided for the optional Display Power Sensor. This device detects when the projector power is on.

All connectors are provided. Cables are the responsibility of the installer. The two standard accessories described in this section are the Infrared Emitter and the Room/Relay custom control. Figures 2-7, 8 and 9 show accessory connections. Optional devices (SCP 100, the IR Broadcaster and the Power Sensor) are also covered in their separate user’s guides and are summarized in Appendix B of this manual.

Comm Connector and Infrared Emitter

This connector is for projector control, and can be used in different ways:

1a. Connect the IR Emitter (included) to transmit all of the “learned” IR commands to the projector. The IR Emitter includes a black cable with two wires, one has a white stripe. Insert the wire with the white stripe into the carrier/signal pin (C) and the solid black wire to either ground contact (B or D).

1b. If a wired remote can be plugged into the projector, that cable will use pins A (signal) and B, as shown in Figure 2-7.

Figure 2-8. The IR Emitter can be used from the Comm connector or through an IR Broadcaster.

2.To install and use the optional IR Broadcaster, and to use emitter with the IR Broadcaster, see user’s guide 68-392-02. For some projectors, the IR Emitter must be used with the broadcaster.

The standard IR Emitter transmits infrared signals over a short, narrow range, while the IR Broadcaster covers a wider, longer area. Both of these devices transmit only the IR commands that have been stored in the System 5, either through “learning” or by uploading from Extron’s IR library. If the broadcaster is installed, the emitter may not be needed.

Room/Relay Connector

normally closed

normally open

The Room Relay contacts are shown in Figure 2-9. One relay has two sets of contacts – one set is normally closed and the other is normally open. When the Room function is active, the normally closed contacts are open and the normally open contacts are closed.

	The contacts can be programmed to operate either of
	two ways: latched (press-on, press-off) and momentary
to Room	or timed (press-on, time-out-off, default = 1/8 second).
	Timing can only be set through Windows® control
control	software, through a PC.
equipment	The system designer can use these contacts any way
	he/she desires as long as the contact specifications of
	24 volts at 1 ampere are not exceeded.

Figure 2-9. The Room Relay has two sets of contacts.
