2.1 Configuration
2.1.1 Power Configuration
The unit can operate in several different power-on modes:
MODE
#ON/OFF SWITCH DESCRIPTION
A. Unit turns ON when
ON switch pressed
and Off when OFF
switch pressed.
•When unit is first turned ON or any time the ON button is pressed, data is transmitted
•When a change of state takes place, data is transmitted.
•If a function is still active (button is held) data is transmitted every 1 out of 10 packets.
•If no functions are active, data is transmitted 1 packet out of 30.
•If STOP is pressed, data is transmitted and then transmitter turns OFF. Receiver outputs will
default to initial state.
B. " •same as Mode 1 except that outputs retain last state on sending STOP.
C. Unit turns ON when
any function
depressed
•When a button is pressed, data is transmitted
•Transmitted will timeout in 30 seconds
•If STOP is pressed, all outputs in the receiver shall revert to their default state.
2.1.2 Output Configuration
A. MOMENTARY
Outputs directly reflect inputs. Outputs are ANDed with 'MAIN" function. This means
that if a button is pressed and the RF carrier is lost, the output will automatically clear.

B. TOGGLE
Each output pair is independently toggled and latched. Every time a button is pressed, its
corresponding output toggles. In the event of loss of carrier, the status of the output will
either retain its state or turn OFF depending on the POWER ON mode selected.
C. INTERLOCKED
Each of the 8 outputs are paired. Within each pair, only one output can be on at one time
(ie. interlocked). The default outputs shall be odd numbers OFF and even numbers ON.
Whether the pairs retain last state or default upon loss of carrier shall depend on the
POWER ON mode selected.
2.1.3 Link Mode
Sends out all configuration data including the factory programmed ID to the desired receiver
2.1.4 Security Configuration
In certain cases it may be desirable to prevent accidental use of the unit by preventing anyone
except authorized personnel to activate the unit. Entering the SECURITY MODE shall enable a
user to program in a unique 4 digit startup ID. This ID must be entered while simultaneously
depressing the ON switch.
2.2 Normal Operation
During normal operation, the unit will function like an 8 channel transmitter. The specific
functions of each button is defined during device configuration.
