Description

The GIGALINK™, GLR2702240 is an 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. This state-of-the-art invention brings a new dimension in the world of Remote Control technology in domestic, commercial and industrial applications.

The toroidal transformer on this receiver is 25-30% more efficient than the conventional types. It has a low operating temperature, low hum and low stray magnetic field.

Connection to the receiver is via a five-way screw-type terminal block. An on board LED indicates when power is connected and an extra LED on the board to indicate when the relay is activated. There is a test button for the relay output to test your connections.

The receiver’s high capacity output relay is capable of switching up to 16 Amps of resistive load and up to 8 Amps of inductive load. A world first for a standalone receiver.

The receiver can be mounted to a Quick Mount or in a weatherproof case with an IP66 rating.

Coding

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 2-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
Setting Channel
(Output Relay)
OFF
OFF
1
ON

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 2-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 2-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 2-way dipswitch. Dipswitch 1 corresponds to relay channel 1 and dipswitch 2 corresponds to relay channel 2.

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 2-way dipswitch. This will enable corresponding relays to latch.

Receiver Modes

Care must be taken, not to bring a receiver near strong magnetic fields, such as DC-Motors, speakers, magnets for reed switches, transformers etc. as it would magnetise the coils and may cause severe de-tuning.
