GLR2701SS, GLR2702SS
1 & 2-Channel 27MHz Gigalink™ Receiver with Open Collector Output
Features
• One or two channel outputs
• Open Collector Output
• Available with either a Molex female or terminal block connector.
• Uses Gigalink technology, this involves using a receiver cable to
program the transmitter. Some transmitters and receivers are
programmed through the air. This is very risky since another person
can grab your code.
Applications
• Security, wireless activation/deactivation of domestic or industrial alarms
• Gate operation
• Panic buttons
• Remote Activation of lights
• Simultaneous operation of multiple on/off functions
Description
The GLR2701SS and GLR2702SS use the advanced GIGALINK™ technology to combine the decoding
system and FM receiver to form the new GIGALINK™ Strip receiver. The receiver user has the choice of one
or two channel outputs. The GLR2701SS has a single channel output and GLR2702SS has two channel outputs.
The outputs are solid state using the BC337 transistor with open collector. When the outputs are switched to
ground the receiver receives the correct code from the GIGALINK™ transmitter.
The GLR2701SS and GLR2702SS are available with either a terminal block or the Molex female connector.
The terminal block is used for connecting your external wires such as the supply and the antenna, using the
screw type connection.
The six-way female connector is used to integrate a 27MHz receiver onto a printed circuit board. The six-way
male connector is soldered onto the printed circuit board, requiring the 27 MHz receiver. The male connector is
available from Elsema as a Nylon 6-way male low profile connector, part number 6WLP or high profile
connector part number 6WHP. See design dimensions page for more details.
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
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 channel 1 output and
dipswitch 2 corresponds to channel 2 output.
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.
