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. CONGRATULATIONS! YOU ARE DONE. If you experience any problems, please call 1-800-258- 4623 or 1-714-990-2300 for international calls. OPERATION 7 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. DIP SWITCH OFF ON Not Used X Sync on Green X Ch1 Horizontal Delay X Ch2 Horizontal Delay X ID Bit 1 X ID Bit 2 X Table 7. Dip-switch default settings 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. 7.2 HORIZONTAL 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 8 INTERFACES position of the image can be adjusted through the Horizontal Position Control knob located on the front panel. Similarly, one can only adjust the position of the image on the display for Input 2 using the Horizontal position control knob when the CH2 Horizontal Delay switch is in the OFF position. 7.3 I.D. BIT SWITCH 1& 2 Many computers use ID Bits or “Sense Pins” to recognize that a monitor has been connected to its video output port. Often, these ID Bits will allow the computer to recognize what type of monitor is connected in terms of its scan rate compatibility. When the ID Bit switch is in the ON position, the VA6831FC allows the main ID Bit (pin 4 on the input connector) to be connected to the Ground signal. This is used primarily when interfacing laptop computers to imitate the presence of a local monitor. Typically, this recognition will take place during the boot up stage. If your Interface does not output video on the display, then place this switch in the ON position and reboot the computer. When left in the OFF position, this ID Bit will be passed through to the local monitor output port.
