SWITCHERS
With this configuration, the master unit has ultimate control over the slave unit.
The following voltages apply for selecting the required channel:

values connected to ground any channel can be selected. Although the channel selection next to the relay contact is latching and will maintain the last relay selected channel, it is recommended that momentary contact closures not be used. Typical resistor values and wire connections are shown below.
In some cases, it may be preferable to use a

These voltage levels can be set using analog outputs from different control systems or spare dimmer control outputs.
7.5 MANUAL LOOP CONTROL
Loop control is used when multiple units of the MX2216RM are connected to form a single switcher. When the input channel button is pressed the loop control pin is internally grounded and the MX2216RM Switcher selects INPUT 4 as the default input.
In this configuration, the loop control pin 6 on the 9 pin D connector is connected to the same pin on all switchers.
