Switcher Option Module Installation
Chop Chop alternates between two selections at approximately a frame
rate. This function is intended for system calibration and is not an artistic
feature.
Chop is started by pressing one source select button on the Remote Aux
Panel, then double pressing the second source select button. Chop is
stopped by pressing any source select button on any aux panel. Chop must
be enabled using the switches on the rear panel of the Remote Aux Panel
(see next section).

The rear panel includes a number of switches that control operating modes,
such as address, bus enable, delegate enable, and test mode. Settings of
these switches are explained below.
