Installing the SDI Video Matrix Switcher

6.5Configuring the Sync

On the VS-1616SDI, you can select one of the following, as the sync input:

￿EXTERNAL SYNC ANALOG BNC connector

￿INT# 1 DIGITAL BNC connector

￿MTX (Sync from Matrix) RS-485 Terminal Block connector, when using multiple machines1

Configure the sync via the SWITCHING METHOD Menu command setting2. When setting up multiple machines (for example, a 48x64 switcher), linking a common sync to all the machines may be necessary to facilitate simultaneous vertical interval switching.

Usually, the easiest method is to choose the sync source from the first machine (for example, from the VS-1616Vcomposite video unit) and then connect all the terminal block connectors.

In this case, set the first machine to select the sync source from the external sync connector or from the INPUT # 1 connector. This sync is now available to the other machines via the RS-485 terminal block connector, as Figure 8 and Figure 9 illustrate. Select the MTX sync on the other machines that receive that sync.

6.6Connecting the Keyboard Extension

Connecting dry contact-closure switches to the Keyboard Extension (EXT. KEYS) connector enables you to route an input to an output by remote control from a distance of up to 1000 meters. These IN and OUT keys are expandable3. Figure 11 illustrates how to connect the Keyboard Extension (EXT. KEYS):

1 Refer to section 8￿ .3.1

2 Refer to section 8￿ .3

3 Add an unlimited number of push buttons to the existing keys (in parallel) by attaching one end of the push button to the corresponding number and the other end to the IN or OUT terminal
