series transmitters and an ANT27L antenna, an operating range of 350
metres (980 ft) is possible.
• Two relay outputs. Both outputs can be operated simultaneously.
• Crystal controlled for high stability and performance.
• Dual Conversion to reduce interference.
• Uses micro-controller technology that can be re-programmed to suit
unique applications.
• Momentary, latching and security latching output modes is user
selectable.
• Power ON LED indicator.
• Test buttons for relay.
Applications
• Automatic gates, security, timer controlled outputs and simple on/off functions etc
Description
The GIGALINK™ 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.
The GLR2702 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, three 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.
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 multi channel 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. To activate the security latching mode, a link needs to be soldered into the
hole marked as latching.
Customised Software
Custom output modes can be programmed to do special functions. Call Elsema for more details.
