Operation, CONGRATULATIONS! YOU are Done

INTERFACES

light on the front panel of the VA6831FC should turn on.

Step 4. Connect one end of the input cable to the video output of the computer and the other end to the 15-pin HD input connector of the VA6831FC. Repeat this step if two computers are to be interfaced.

Step 5. Connect a cable from a local monitor to the 15-pin HD Local Monitor Output connector of the interface. Repeat this step for a second local monitor if two computers are to be interfaced. It is not necessary to terminate this output with a termination plug if a local monitor is not attached.

Step 6. Connect one end of an output cable to the main output’s BNC connectors of the VA6831FC. Connect the other end to the RGB input on the projector, or presentation monitor. One can use either a 4 BNC or 5 BNC coaxial cable depending on whether the system is designed as RGBS or RGBHV. Please note that if the projector has a 15-pin HD connector, five BNC to 15-pin HD cables (part # MS8102CA) are available from Altinex.

Step 7. Make sure that the dip-switches are properly set according to Section 7.

Step 8. Please adjust the Horizontal position of the image as described in Section 4.5.

If your computer and display device are turned on and you see a good clear image, you have successfully interfaced your computer with the video display.

OPERATION

The settings of the VA6831FC Interface can be adjusted using the dip-switches in Table 4. There are no other adjustments necessary to operate the unit. The VA6831FC will operate successfully as long as the cables are attached properly and technical specifications are followed.

7.1 SYNC ON GREEN OUTPUT SWITCH

Often systems that use large matrix switchers are designed to switch signals in RGsB format. In these types of systems, the ability of the VA6831FC to output the Sync signal on the Green signal can be very useful. It is important to know that the VA6831FC will not separate Sync from the Green signal if the input is RGsB. It will simply amplify the RGsB and pass it through. It will combine the Sync signal with the Green Video signal when the Sync on Green dip-switch is in the ON position, regardless of whether the input sync is RGBS or RGBHV. If the desired output is RGBS or RGBHV, then leave the Sync on Green dip-switch in the OFF position.

7.2HORIZONTAL DELAY REMOVAL (CH1 & CH2)

The VA6831FC offers the ability to bypass horizontal delay. This may be necessary when interfacing with projectors or monitors with sensitive sync inputs, particularly with LCD projectors. By setting the appropriate dip switch for Input 1 or Output 2 to the ON position, the VA6831FC will output the same type of Sync signal as is being fed into it from the source. In this setting, Horizontal position control of the VA6831FC is disabled and any adjustments to the image position must be done at the monitor or projector. If the CH1 Horizontal Delay dip- switch is in the OFF position, then the horizontal
