Making Connections • Chapter 2

_______ Although all three outputs may be connected at the same time, only one

can be active at one time, as determined by the input format. In a typical installation, an LCD projector may have inputs for all three formats. In such cases, each of the three System 5 outputs would be connected to the same projector.

11R, G, B, H/HV, V BNC connectors, for RGBS or RGBHV output. The green LED indicates when the selected input is RGB format (PC1, PC2 or PC3) and this output is active.

12Y and C BNCs for S-video output. A BNC-Din adapter may be required. The green LED indicates when the selected input is S-video format (VID1 or VID2, if set up for S-video format) and this output is active.

Figure 2-5. The right side of the rear panel has three video outputs, plus audio and options.

13VID is for Composite video output. The green LED indicates when the selected input is composite video format (VID1 or VID2, if set up for VID format) and this output is active.

14Audio PreAmp Out – This output has the audio signal from the selected input and should be connected to a stereo audio amplifier. The signal is the same as item 18, at a low level. Both audio outputs are affected by the volume control. See detailed section on audio connectors.

_______ Audio breakaway is available if programmed through RS-232. If so, the

selected audio input may be different from the selected video input.

15Aux1 and Aux2 each can accommodate a connection to an optional external control panel (SCP 100). See the SCP 100 User’s manual and “Connecting Accessories” later in this chapter. See specifications

_______ The AUX 1 & 2 ports of the System 5cr provide a total of 500mA. This is

split between the two ports offering 250mA for each port.

16Relay Contacts (one normally open pair and one normally closed pair) are controlled by the “Room” button on the front panel to control external functions, such as lighting, display screen up/down, etc. See “Connecting Accessories” later in this chapter.

Comm – This is the connection for the IR emitter or the optional remote IR Broadcaster. Both of these devices transmit only learned IR signals from the System 5 to the projector, IR 40 commands are not included. The optional Broadcaster covers a much wider area than the emitter.

_______ A 12VDC, 500mA output is provided on the Comm. (IR Emitter) port.

17Optional Display Power Sensor Input – Detects projector power on.

18Amplified Output – connect directly to audio speakers.

19RS-232Control Port – connect a host, such as a touch panel, a PC, etc.
