Internal DIP Switches

Operation

Internal DIP switch settings determine the operating mode of the RGB 118 and RGB 118 PLUS. Changing the switch settings requires removal of the top and bottom halves of the case as described below.

Opening the RGB 118 or RGB 118 PLUS Case

To open the RGB 118 or RGB 118 PLUS case, remove the screw from the bottom of the case (see Figure 1 on facing page). This enables removal of the top and bottom halves of the case as shown in Figure 2.

Changing a Switch Setting

The switches on the DIP switch module used in the RGB 118 and the RGB 118 PLUS are the slide type (see drawing, Figure 3 on facing page). To change the position of the slide switch, a small screw-driver is used to push (slide) the switch to the desired position (enable or disable).

Setting Internal DIP Switches

Internal DIP switches SW3-1,2, SW4-1, 2, 3 and SW5-1,2 affect RGB 118 and RGB 118 PLUS operation as follows:

SW3-1 SW3-2		Serration/LCD Switch
F1 OFF	OFF	Normal – Serration pulses remain w/output sync
OFF	ON	Serration pulses are removed from output sync 2

SW4-1 SW4-2		SW4-3	Analog Output Switch
F1 ON	OFF	OFF	Normal
ON	OFF	ON	Sync on Green 3
OFF	ON	ON	Sync on Mono 4

SW5-1 SW5-2		TTL Mode Switch
F1 OFF	OFF	Normal
ON	OFF	64 Colors < 18 KHz
X	ON	16 Colors > 18 KHz

Notes:

1.F = Factory setting

2.Required by some projectors

3.When setting the RGB 118 for Sync on Green, you must also disconnect the BNC cable from the external “Sync” output of the RGB 118 and RGB 118 PLUS. Otherwise, sync is output on both green and the composite sync output which may cause abnormal levels of green to appear on the presentation display.

4.Monochrome Composite – Use the Green output only.
