SWITCHERS

STEP:

This feature allows cycling through the inputs one at a time. It is used to select the next input from an ALL OFF condition. If this button is pressed once it switches to the next input in an increasing order. For example, if INPUT 3 is currently selected, pressing STEP SELECT once will switch to INPUT 4. If pressed again INPUT 5 is selected. If INPUT 6 is already selected, and the STEP SELECT button is pressed once, none of the inputs will be selected. This condition is similar to the ALL ON function. By pressing once more from the ALL OFF stage, INPUT 1 will be selected.

7.1.3OUTPUT CONTROL SECTION DELAY:

This function enables Sync Delay Switching in RGBHV and RGBS signals. Sync Delay allows the ”glitch” that normally takes place when switching between high-resolution sources to take place off screen. When the Sync Delay feature is enabled, the video portion of the image (RGB signals) is disconnected before the sync portion (H&V SYNC or CSYNC). When connecting the input, the video portion of the signal (RGB) is restored shortly after the incoming sync portion of the signal is connected. This delay time is factory pre-set to

2.5seconds. By pressing this button once, the SYNC DELAY feature is enabled and confirmed through the LED on top of the button. If it is pressed once more this feature is disabled and the LED turns off.

VIDEO OFF:

This feature allows a user to disable only the video (RGB channels) portion of the selected source. The sync portion (H&V, SYNC or CSYNC) of the selected source will continue to be sent to the display. This feature can be very helpful when the user does not want the display to go into a ”no display” or “no signal” mode (e.g. some data monitors will display a blue screen if no signal is present). To disable the video portion of the selected input, press the video off button once, the LED on the top

button should light up. To enable the video portion, press the button again and the LED will be in an OFF position. This feature is designed to work only with RGBHV, RGBS and RGsB format signals. It is similar to the ALL OFF mode except that there is only sync signal sent to the output for display.

7.2 RS-232 CONTROL

The MX2226AT uses a terminal block type connector for RS-232 communication. The terminal block uses solder-free, screw-down contacts, making it extremely easy to connect the switcher to a control system or to a computer in the field.

Terminal Block Designation

The terminal block is labeled with the proper contact designations: Transmit (TX), Receive (RX), and Ground (GND). Always remember that the Transmit pin from the control system or computer must be connected to the Receive pin on the switcher control port.

Typically, a control system or computer will offer RS-232 connections on a 9-pin D connector or a DB 25-pin connector. The following are two typical cable pin-out connections for RS-232 connections from a PC. Always confirm the pin-outs for your system to insure proper wiring.
