Installation of the RGB 440 using an MBC cable or an MBC buffer  
Shield connections  
If shielded, twisted pair wire such as that in Extron's Plenum Installation Cable  
(figure 8) is being used with the RGB 440 captive screw connector, the shields  
should be connected to connector pin 3 (the center pin) as shown in figure 7.  
The wires that make up the braid shield (see figure 8) should be separated  
and twisted together forming a large multi-strand wire, which is then  
inserted into the receptacle side of the connector. Unused shielded,  
twisted pair wire must be insulated and secured to prevent short  
For the following steps, use the diagram in figure 5A or 5B, whichever applies to your installation.  
1. Turn off the computer and its monitor.  
2. If desired, attach mounting brackets (Extron part #70-077-01, under-desk, or 70-077-02, through-desk).  
3. Disconnect the local monitor cable from the computer and connect it to (A).  
4. Connect the 9-pin connector from the MBC/MBC buffer to “Analog” on the RGB 440 (B). For an MBC  
buffer, connect the small plug at the same end of the cable to "MBC Power" on the RGB 440.

circuits.  
5. Connect the remaining MBC/MBC buffer connector to the computer's video output connector (C).  
6. Connect the PC audio output cable to the RGB 440 Audio input connector (D).  
7. Connect the RGB 440 video output to the output device (E).  
The coax within the Plenum Installation Cable also contains a braid and foil shield which are normally  
connected to ground through their individual connectors (BNC, RCA, etc.).  
CAUTION  
Exposed cable shields (braid, foil, etc.) are potential short circuits. Trim back and/or insulate  
shields with electrical tape or heat shrink.  
8. Connect the RGB 440 audio output to the audio output device (F).  
9. Apply power to the RGB 440, the CPU and its monitor, and the output devices.

Power  
The RGB 440 requires an external voltage source of 12 to 24 volts AC or DC (500 mA max). Polarity is not  
an issue, even if the power source is a DC voltage. Simply insert the power plug into the connector labeled  
POWER ((H) on figure 2) on the rear panel of the RGB 440. An optional 12 VDC external power supply is  
available from Extron (Part #70-055-01). A power plug (included with RGB 440) must be soldered to the  
power source wires. The procedure follows:  
Figure 5B —  
Using an MBC buffer.  
(F)  
CAUTION  
DO NOT connect the power plug/RGB 440 to a power source greater than 24 volts AC or  
DC. To do so could cause serious damage to Extron equipment and/or User’s equipment.  
To connect the power plug to the wires from the power source, see figure 9 and do the following:  
1. Unscrew the black plastic cover from the plug.  
(C)  
(D)  
(E)  
2. Insert the wires from the power source through the tapered end of the black plastic cover.  
3. Solder one wire to terminal 1, and the other wire to terminal 2.  
(B)  
4. Before plugging the power plug into the RGB 440, apply power to the voltage source and, using a  
voltmeter, verify that the voltage at the plug is in the range of 12 to 24 volts AC or DC.  
(A)  
5. Reinstall the plastic cover on the plug and insert the plug into the RGB 440 power connector.  
NOTE  
The front panel POWER LED is on only when power and video sync pulses are present.  
DIP switches

AC or DC source  
(Extron 12VDC power supply)  
part # 70-055-01  
Video projectors of different types or from different manufacturers may have slightly different sync pulse  
requirements. DIP switches on the RGB 440 front panel enable the user to modify output sync (except SOG)  
by enabling or disabling vertical sync serration pulses and enabling or disabling Digital Display Sync  
Processing (DDSP).  
The front panel slide switches are shown in figure 6. The Serr switch, when on  
(up position), will result in the removal of serration pulses from the output  
composite sync signal. The DDSP switch, when on (up position), provides Digital  
Display Sync Processing, which may be required for digital display devices  
which exhibit an unstable display. The H Shift control is disabled when the  
Plastic cover  
DDSP switch is in the on position.
