Definitions and Descriptions


Antenna diversity is used in the WES43301R receiver. The receiver can use two antennas to improve the quality of the wireless link. Often in civil and mining environments there may not be a clear line of site between the remote and the receiver. The signal is reflected along multiple paths before finally being received, each of these bounces can introduce phase shifts, time delays, attenuations and distortions that can disrupt and interfere with the receiver.

Antenna diversity is especially effective at mitigating these multi-path situations. This is because two antennas offer the receiver several observations of the same signal. Each antenna will experience a different interface environment, therefore if one antenna is experiencing a deep fade it is likely that the other antenna has sufficient signal. Such a system can provide a robust link with extended range.


The receiver is factory set to enable over 17 billion encrypted codes for security and to minimise un-intentional shut downs.


The relay output on the receiver can function in either momentary or latching mode.


Output is active as long as the transmitter button is pressed.


Output remains active until the transmitter button is pressed again or the ignition of the Vehicle/Equipment is turned off and returned to the on position the receiver will reset.


Customized output modes can be programmed to do special functions. Advise Thompson Safety Pty Ltd prior to installing.


Wireless remote controls use either a Fixed Frequency (FF) or a Frequency Hopping Spread Spectrum (FHSS). Thompson safety have sourced remote controls that operate on five frequencies, and customers ask about the benefits of doing this versus using a single frequency.


Fixed frequency remote controls use a single frequency channel to transmit and receive the data. In each region of the world there are licence free bands (ISM Bands), for example Australia and Europe is 433 MHz or USA is 915MHz. Licence free bands are usually used by the public and if you get two or more users in the same area using the same frequency the transmissions can be corrupted. A corrupted transmission normally causes the receiver not to be ACTIVATED when the remote-control button is pressed.


Frequency Hopping Spread Spectrum (FHSS) does exactly what its name implies – the carrier is automatically changed to hop from frequency to frequency. This allows the transmission to occur over several frequencies which allows the data to tolerate a significant amount of in-band interference providing that it affects only part of the spectrum. In general, if 1, 2 or even 3 frequencies are interfered in a 5-frequency hopping system it will still operate at its full operating range.

Since each FHSS remote control has its own frequencies and hop sequence, the CHANCES of two remotes on the same frequency is greatly reduced. In the event of a hop clash, both remote messages are corrupted, however the probability that both remotes will hop to the same frequency a second time is very low. Therefore, a FHSS remote control system is more immune to interference when compared to a single or fixed frequency remote control system.

Coding remotes and receivers can be done in two different ways. 1. Using the receiver 2. Using another remote


1. Press and hold the program button on the receiver
2. Press the remote button for two seconds, receiver LED will flash and then turn green
3. Release the button on the receiver and the remote
4. Press the remote-control button to the receivers output


1. Open the case of the remote control that is previously programmed and press the program button on the back of the board
2. Press the new remote control button for two seconds or until the green light on the previously programmed transmitter aluminates then release buttons
3. Press the new remote control again to test the receiver output


Short the code reset pins on the receiver for ten seconds. This will delete all the remotes from the receiver’s memory.


Thompson Safety can supply a “programmer” that allows you to add and delete certain remotes from the receiver memory. This is used when a remote control is lost, damaged or stolen and the owner wants to prevent un-authorised use.


This chip is used to backup and store the contents of the receiver. When there are 100’s of remotes programmed to a receiver the installer is able to backup the receiver memory in case the receiver is damaged.
