The Kramer RC-20TB 2-Button Contact Closure Switch

Congratulations on purchasing your Kramer RC-20TB single slot wall plate insert 2-Button
Contact Closure Switch which is ideal for using as a means of remote control in boardrooms

and conference rooms. It can be used with the VP−81SID step−in switcher or any other
Kramer product with contact closure control.

The RC-20TB front panel has two momentary switching buttons (labeled A and B). On the rear
are remote momentary contact closure terminal block connectors that connect to a remote
switch terminal block connector.

Figure 1 shows the RC-20TB front panel and the pinout on the rear:

The RC-20TB can remotely switch the inputs of a machine via its remote contact closure
terminal blocks. For example, you can connect the RC-20TB to the REMOTE contact closure
terminal block connectors of the Kramer VS-162AVM 16x16 Audio-Video Router with Preview
Monitor (download the up-to-date Kramer user manual at: www.kramerelectronics.com), to
remotely switch one of two inputs to the output by momentarily pressing button A or button B,
respectively.

Figure 2: RC-20TB connected to two SID-H Units

To connect the RC-20TB, as illustrated in the example in Figure 2 and Figure 3, connect the
remote terminal block connectors on each SID-H machine to the A and B terminal block
connectors of the RC-20TB.

Momentarily pressing button A or B on the RC-20TB activates the STEP-IN process (allowing
this machine’s input to be selected on the VP-81SID) in Machine A or Machine B, respectively.

In the example illustrated in Figure 2 two SID-H HDMI Step In Commander units are
connected to RC-20TB.
