With this configuration, the master unit has ultimate
control over the slave unit.

7.4 CONTACT CLOSURE (ONE WIRE ANALOG)
CONTROL

The one-wire control is an alternative to a multi-
wire contact closure control. This control pin allows
you to select different channels based on the DC
voltage level on pin 7 of the 9 pin D connector.
Internally, pin 7 is pooled up to 5 volts by a 10k
resistor. Thus, by selecting the proper resistor
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
seven-conductor wire to control the switcher with
contact closures. The 

RC5204CC

 adapter is

available to accommodate this need. The pin outs
for this adapter are as follows:

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.
