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 an eight-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.

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
For code programming, please refer to the separate programming instructions.
When programming is completed and the GIGALINK cable is removed from the receiver-coding socket, the 2-
way dip switch is used to select different output modes. This is described below.
Output Modes
Relay output on the receiver can function in either momentary or latching mode. By default the mode is set to
momentary. Modes selectable from the 2-way dipswitch. Dipswitch 1 corresponds to relay channel 1 and
dipswitch 2 corresponds to relay channel 2.
Factory Default = Momentary
Momentary - Output is active for as long as the transmitter button is pressed.
This is a standard mode on most automatic gates or garage door openers.
Latching - Output remains active until next press of the transmitter button.
Similar to switching "on" and "off" a light.
Security
Latching
-
Output remains active until power to the receiver is removed. Similar to security alarms
and fire alarms.
Customised Software
Custom output modes can be programmed to do special functions. Call Elsema for more details.
240 AC Supply, Antenna and Relay Connections
AC power supply and relay connections are via the pluggable type terminal block. Antenna is via a two-way
pluggable type terminal block. Do not connect the supply to the 2.5-mm coding socket since connection will
damage the microcontroller.
Applications
The receiver output can be set to different modes which allows it to be used in many diverse applications such
as automatic gates, security, timer controlled outputs and simple on/off functions etc.
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.
