3 Overview The VS-211HA is a high-performance automatic standby switcher for HDMI video and unbalanced stereo audio signals. The VS-211HA can be used as a manual 2x1 switcher or as an automatic switcher. The switcher either uses a priority input or last connected input. In priority switching, the signal automatically switches to the secondary input if the primary signal is lost. If the primary signal reappears, the unit automatically switches back to the primary input.
3.1 Defining the VS-211HA Automatic HDMI Standby Switcher This section defines the VS-211HA.

4 Connecting the VS-211HA i Always switch off the power to each device before connecting it to your VS-211HA. After connecting your VS-211HA, connect its power and then switch on the power to each device. To connect the VS-211HA, as illustrated in the example in Figure 2, do the following: 1. Connect the HDMI input source 1 (for example, Blu-ray player 1) to the IN 1 HDMI connector. 2. Connect the HDMI input source 2 (for example, Blu-ray player 2) to the IN 2 HDMI connector. 3.
Figure 2: VS-211HA Connections 4.1 Connecting the REMOTE Terminal Block Connector If DIP 1 is set ON to manual you can switch the active input by using contact closure switches. To do this, connect the appropriate REMOTE input terminal block connector pins to a contact closure switch (see Figure 3).
5 Operating the VS-211HA The VS-211HA works in three modes: 5.1 Manual mode (see Section 5.1) Automatic mode (see Section 5.2) Override mode (see Section 5.3) Using the Manual Mode In manual mode the VS-211HA only switches when the remote contact closure switches are momentarily pressed. If you switch to an inactive input source, the output is blank. Note: A source is considered active only when there is an active clock signal coming from the source.
To set Automatic/Priority mode: Slide AUTO/MANUAL DIP 1 up to AUTO and LAST/PRIORITY DIP 2 down to PRIORITY In Automatic/Last mode, the last connected input is sent to the output If Inputs 1 and 2 are active when the VS-211HA is powered on, Input 1 is sent to the output (as the priority input) If Input 2 is disconnected, Input 1 is still sent to the output If Input 2 is reconnected, Input 2 is sent to the output For example, a salesman connected to Input 1 displays a presentation on the AV syst
