GLT4330112E, GLT4330212E, GLT4330412E, GLT4330812E, GLT433xx12NC
1, 2, 4 & 8-Channel, Gigalink 433MHz. 25mW Transmitters
Features
• One, two, four & eight channels.
• Wide supply connection – 11.0 to 24.0 Volts DC.
• More than four billion code combinations and no dipswitch visible, enabling it to be used for high security applications.
• 433 MHz transmissions. No interference from electrical noise and other signals.
• Microcontroller technology, replaces the traditional dipswitch coding which eliminates any possible code grabbing.
• Built-in battery monitor. Red LED indicates to the user when the battery is flat.
• Ability to program un-limited number of transmitters to a receiver, making expandability unlimited.
• 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 25mW 433MHz GIGALINK™ transmitters are 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 GLT43312 series state-of-the-art invention brings a new dimension in the world of Remote Control technology in domestic, commercial and industrial applications.
Operating Distance
An operating distance (with an ANT433SSMA antenna) of 1500 metres is possible. Range test was done in an open area test site with line-of-sight operation.
Case
The GLT433xx12 Series transmitters are enclosed in an alloy metal case, While the GLT433xx12NC is PCB assembly only.
The transmitter modes are user selectable by simply setting the 2-Way dip-switch on the transmitter board.
Transmitter Modes
 |
Off Delay 2 – 62 seconds
Transmitter will transmit a 1.5 second transmission burst and then stop for the "off delay" time selected. The "off delay" time is user selectable between 2 to 62 seconds by adjusting the trimpot of the transmitter board. If another channel is activated during the "off delay" period the new channel will be transmitted immediately. When the "off delay" time lapses, transmitter will transmit another burst. The transmitter will cycle (transmission and off delay) indefinitely, if at least one channel is activated and the supply is connected. |
 |
Off Delay 10sec – 10 minutes
Same as mode 1 except the "off delay" is user selectable between 10sec to 10 minutes. |
 |
Continuous transmission
Transmitter will transmit continuously, if at least one channel is activated and supply is connected. A transmission limit of five minutes is used to comply with local radio regulations.
To activate a receiver longer than 5 minutes, use a delay off feature in the receiver (GLR43301) and transmitter. The delay off feature in the receiver needs to be set more than the transmitter. This ensures that the transmitter keeps resetting the off delay in the receiver. Refer to Application Note |
 |
1.5 – 10 seconds one burst transmission
Transmitter will transmit one burst and then go to standby or sleep mode. Adjusting the trimpot will vary the burst length. When the code is changed and supply is connected, transmitter will immediately emit one burst of the new code. |
| Sleep mode (20 uA) is activated when all 8-channels are OFF, this applies to all four modes. |
