Description
FMR15102240 can be used in noisy environment and is least affected by electrical interference. This makes FMR1512240 an ideal choice for use in heavy industrial environment.
Different Modes for the Output
This 2-Way dip switch is situated beside the microcontroller. (refer to the picture below)
The two-way code switch allows individual control of each relays output mode. In the momentary mode the output relays are only activated while the correct signal is received. In the flip-flop mode the output relays are toggled with every correct incoming signal. This enables the direct use for switching on/off lights etc. In flip/flop mode, the relays are off at the initial "power-up".
Latching Feature
Inserting a .4” link into the latching link holes will configure the channels to latching “ON”, when the correct signal is received. To turn relay “OFF” power to the receiver must be momentary turned “OFF”.
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:
- Two channel receiver will have a 2 way dip switch.
This DIP switch on the right side of the 12 way dip switch denotes the channel. See table below.
Generally to use a 2 channel Tx to 2 channel Rx match all the 14 dip switch (12way + 2way just on the right side of the 12 way).
To use a 2 channel receiver with 2 x single channel transmitters, first match 14 dip switch and then the Tx with Sw15 OFF will activate the Ch1 on the receiver and the Tx with Sw15 ON will activate the Ch2 on the receiver.
