Description
The GIGALINK™ , is the most advanced Remote Control technology available in the world today. GIGALINK™ is an invention that has revolutionised the entire Remote Control technology including Elsema’s earlier version of FMT- … and FMR- … series. The GLR.... series state-of-the-art invention brings a new dimension in the world of Remote Control technology in domestic, commercial and industrial applications.
The innovative microcontroller technology replaces the traditional dip switch coding which eliminates any possible code grabbing. Special features such as over four billion code combinations, ability to program any number of transmitters to any of the receiver outputs, four user selectable modes, dual conversion superhet and operational over a wide voltage range all adds up to the most advanced and secure Remote Control available.
The multi channel receivers are available with three or four channels.
Four billion codes
The user can easily change the code on all the channels. Momentary joining the two CC pins on the receiver board sets all channels to one random code. One of 4,294,967,296 possibilities is selected.
Code Programming - Single
During single code programming, the 4-way dip switch selects the channel to be programmed. The table below shows the setting to select a different channel.
| Dip Switch 1 |
Dip Switch 2 |

After selecting the correct channel, the receiver channel is ready to be single code programmed.
Follow the steps outlined in the receivers instruction sheet titled single code programming to complete the code programming.
Code Programming - Channelised
If all the receiver channels are to be programmed onto a multi channel transmitter, then follow the steps outlined in the receivers instruction sheet titled channelised code programming. This does not require the user to set the 4-way dip switch since all receiver channels will be programmed sequentially onto the transmitters channels.
The receiver power must be connected when single or channelised code programming.
When programming is completed and the GIGALINK cable is removed from the multi channel receiver-coding socket, the 4-way dip switch is used to select different output modes. This is described below.
Different Modes for the Output
Modes are user selectable from the 4-way dipswitch. Dipswitch 1 corresponds to relay channel 1 and dipswitch 2 corresponds to relay channel 2 etc
| Momentary Mode |
If the dipswitch is “off” the relay will be in momentary mode. |
| Flipflop Mode |
If the dipswitch is “on” the relay will be in flipflop mode. |
| Latching |
If latching is required (Relay stays on until power is removed) the latching link should be inserted and soldered into the two holes to the right of the 4-way dipswitch.
This Link will enable the corresponding relays to latch. E.g. When dip switch 1 is “on” relay 1 will be in latching mode. When dip switch 2 is “on” relay 2 will be in latching mode. And so on. If the dip switches are off the relays will be in momentary mode.

AC/DC Supply and Antenna
AC/DC power supply and antenna is connected via a screw-type terminal block. Do not connect the supply to the 2.5-mm coding socket since connection may damage the microcontroller.
Unique Code System
The microcontroller EEPROM allows large volume users to have a unique code. This enables Elsema to offer everyone "your own" radio control.
Case
The three or four-channel receiver is supplied without a case, this allows the receiver to be integrated according to your needs. Elsema has available a Quick Mount bracket which enables easy mounting to walls, roof etc.
