Internal DIP Switches

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

OFF OFF Normal – Serration pulses remain w/output sync

OFF ON Serration pulses are removed from output sync

SW4-1 SW4-2 SW4-3 Analog Output Switch

ON OFF OFF Normal

ON OFF ON Sync on Green

OFF ON ON Sync on Mono

SW5-1 SW5-2 TTL Mode Switch

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.
