IN2200RS Operation Manual - V1.1 01/03/2001

Problem: The output image is missing a color.

Solution: The RGB output cable may be bad. Try switching connections on the output

to verify that the bad color’s cable is OK (Example: If there is no red, try running the
green output through the red cable and see if green is displayed or not).

Problem: The image on the display device is not centered.

Solution: Adjust the Position Control (see page 9).

Problem: The position control’s horizontal adjustment is not working.

Solution 1: Check the dipswitch settings to see if the horizontal position control has

been disabled.

Solution 2: The input setting may be RGsB (sync on green). The horizontal position

control does not work with RGsB input signals.

Problem: The front panel controls are not responding.

Solution: The front panel operation dipswitch may be disabled.

Problem: The image on the display device is fuzzy.

Solution: Adjust the Sharpness / Gain Control until the image regains its detail.

Problem: The output image is very bright and appears “overdriven” with poor contrast.

Solution 1: The gain may be set to high. Reduce the gain as required.

Solution 2: Check the contrast and brightness settings on the display device. Many CRT

display devices look best with the contrast set toward the upper end of the adjustment range
(75 - 95%) and the brightness set towards the middle of the adjustment range (40 - 60%).

Problem: There unit is not responding to serial commands.

Solution 1: Make sure that the baud rates of the controller and the unit match (factory

default is [ACI6] or 9600).

Solution 2: Make sure the controller is configured as eight data bits, one stop bit and no

parity.

Solution 3: Make sure that the correct command codes are being used (factory default is

[CMDCD0] or ‘[ ]’).

Solution 4: Make sure that the connector cable is properly inserted into both / all units.

Problem: There is no audio output.

Solution 1: Verify that power is present and that the power switch is turned on for the

audio source, the IN2200RS and the amplifier / speakers.

Solution 2: Verify that the audio source is connected to the correct input.

Solution 3: The audio output of the IN2200RS is line level audio only. It should be

connected to a mixer / amplifier or to amplified “computer type” speakers.

Solution 4: Verify that the 3.5mm Mini DIN connectors are wired correctly (see the

Stereo Audio Switching Section on pages 16 & 17).

Solution 5: Verify that the internal jumpers are set properly (see the IN2200RS Internal

Controls Section on pages 17 & 18).
