GLT2700/1/2/3/4
27MHz HAND HELD GIGALINK™ TRANSMITTERS
The hand held GIGALINK transmitters are 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 GLT2701/2/3/4
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 by eliminating
any possible code grabbing. Special features such as over four billion code combinations and the
ability to program any number of transmitters to a receiver adds to the most advanced and secure
Remote Controls available.
The hand held GIGALINK transmitters have a microcontroller in-built single and channelised code
programming system that provides flexibility in programming each channel to different receivers. Each
transmitter can store to its EEPROM, up to four random channels allowing the user to program each
channel from different single channel receivers. This is achieved when single code programming the
transmitter channels from a GLR2701, which is a single channel GIGALINK receiver. If the
transmitter is single code programmed from a multi channel receiver, the selected receiver’s channel is
programmed to the selected transmitter channel. The channels can be selected by using the dip
switches on the receiver and by pressing the appropriate channel button on the transmitter.
Channelised code programming programs all the channels, from a multi channel receiver, to the multi
channel transmitter. That is, channel one on the transmitter activates channel one on the receiver and
alternatively. Channelised system can be either used as simple on/off functions or for several channels
to operate simultaneously such as dual or multi action control for example crane transmission control.
The transmitter can be single or channelised code programmed without power connected.
Single Code Programming
This is used for programming one channel at a time to the transmitter. To single code program a
transmitter read receivers setup instructions.
Channelised Code Programming
This is used to program all channels from a multi channel receiver to the multi channel transmitter. To
channelise code program a transmitter read receivers setup instructions.
Applications
The code programming becomes a powerful feature that allows the hand held transmitters to be used in
many diverse applications such as security, gate operation, panic buttons, multiple on/off functions etc.
Battery or DC Supply
Battery operation is optimised using the built-in battery monitoring system. The battery monitoring
system alerts the user when the battery level falls below the low battery voltage. The 1 Hz flash from
the LED during a transmission indicates low battery. This is an indication that replacement of a battery
is necessary.
Normal Operation
The LED flickers at 12.5Hz during normal operation.
Channels
The hand held transmitters are available with 1, 2, 3 and 4 channels.
Custom made front Membrane
Membrane is the front label with the channel etched/printed to it. Customers can purchase the
GLT2700, which is a hand held GIGALINK transmitter without the front membrane. This enables
the customers to fit their custom made membrane that can be a 1, 2, 3 or 4 channels. This has the
advantage of customers only stocking one model to function as a 1, 2, 3 and 4 channel. Details of
membrane dimensions are given on the following page. Customers can even use Elsema’s membrane
tools to manufacture their own membranes.
Continuous or Burst Transmission
The hand held transmitters can be purchased with a choice of continuous or burst transmission.
Continuous transmission will transmit as long as the channel is activated.
Burst transmission will transmit for a predetermined time when a channel is activated. Burst
transmission locks on a transmission, which ensures a fail-safe transmission from a short activation of
a channel. Burst transmission is also required in certain countries where limited transmission time is
allowed.
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 hand held GIGALINK transmitters are supplied with a case. There is also sufficient space on the
rear of the case to place additional stickers such as your telephone contact, local authorities approval
numbers etc.
REGULATORY COMPIANCE STAEMENTS
American Users
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two
conditions:
(1) This device may not cause harmful interference and
(2) This device must accept any interference received, including interference that may cause undesired
operation.
FCC Notice
This device has been tested and found to comply with the limits for a Class B digital device, pursuant
to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against
harmful interference in a residential installation. This device generates, uses, and can radiate radio
frequency energy and, if installed and used in accordance with the instruction, may cause harmful
interference to radio communications. However, there is no guarantee that interference will not occur
in a particular installation. If this device does cause harmful interference to radio or television
reception, the user is encouraged to try to correct the interference by one or more of the following
measures:
•
Reorient or relocate the receiving antenna.
•
Increase the separation between the computer and receiver.
•
Connect the computer into an outlet on a circuit different from that to which the receiver is
connected.
•
Consult the dealer or an experienced radio/TV technician for help.
Caution: Any changes or modifications not expressly approved by the grantee of this device could void
the user’s authority to operate the equipment.
