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).

Setting Rear Panel Switches

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.
