Description

The 151MHz receivers use dual conversion, narrow band FM which makes it ideal for industrial applications. Built into the receiver is a noise and signal strength indicator. The user selectable frequency synthesizer allows for easy installation on a frequency that is not in use, allowing optimal performance in the receiving range.

The receivers output is a relay which is voltage free allowing the user to connect any voltage up to 240VAC with currents of 8 amps.

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.

Noise Strength Indicator
If more than 1 led is “ON” without a valid transmission, this indicates that there is noise on the frequency selected. Change the 3-way dipswitch on the receiver module to select a different frequency. The default setting is for 151.6MHz (All 3 dipswitches “ON”). Below is a table with the Dipswitch settings and the frequencies.
