Description

FMR15101240 can be used in noisy environment and is least affected by electrical interference. This makes FMR15101240 an ideal choice for use in heavy industrial environment.

Different Modes for the Output

This 3-Way dip switch is situated beside the microcontroller. (refer to the picture below)

Modes are user selectable from the 3-way dip switch, shown below.

3-Way DIP Switch Mode Settings The output relay will respond in the following manner when receiving the correct signal from a transmitter
	"Momentary": Relay on, only while correct signal is received
	"Flip-Flop": Relay alternates at every correct incoming signal
	"Delayed Off 1": Relay on, but delayed off for 1-10 seconds, adjestable by trimpot
	"Delayed Off 2": Relay on, but delayed off for 10-300 seconds, adjustable by trimpot
	"Latching On": Relay will energize untiil supply to receiver is momentarily interrupted
	"On-Off": This mode requires a 2-channel Tx. Channel 1 will always energize the relay Channel 2 will always de-energize the relay

Coding
The 12 way dip switch on the receiver sets the 12 bit unique code for the system. This has to be matched to that on the transmitter.
Apart from the 12 way dip switch there will be an additional dip switch depending upon the receiver type:

Single channel receiver will have a 3 way dip switch.

To use a 2 channel Tx to control 2 x single channel receivers, first match the 14 dip switch positions and on the receiver, 15th dip switch OFF is Ch1 and 15th dip switch ON is Ch2.

This DIP switch on the right side of the 12 way dip switch denotes the channel. See table below.
