Description
The GIGALINK™, GLR4330812R, GLR4330824R is 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 GLR4330812R, GLR4330824R 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 and ability to program any number of transmitters to a receiver adds up to the most advanced and secure Remote Control available.
Different Modes for each Output
Modes are user selectable from the 4-way dip switch, shown below. (Dipswitch 4 is reserved for specific customer mode. Normally not used.)
* Dipswitch 4 is reserved
AC/DC Supply and Antenna
AC/DC power supply and antenna is connected to the 3-way terminal block. The shield of the antenna coaxial cable should be connected to the minus ( - ) terminal block.
Do not connect the AC/DC supply to the 2.5-mm coding socket since connection may damage the microcontroller.
Channels
The eight channels are relay outputs using the ULN2803 Integrated Circuit. This IC is inserted to a socket that enables the user to easily change the output stage in case of a damaged output. The ULN2803 IC is available from Elsema.
Simultaneous channel operation is possible with the same transmitter.
Code Programming
The microcontroller built-in code programming system automatically selects the programming mode that provides flexibility in programming each receiver channel to different transmitter channels. In programming mode the receiver sends a random code to program the transmitter channel(s). This is known as reverse programming.
Momentary joining the two CC pins on the receiver board sets all eight channels to a random code. To program the receiver to the transmitter channel(s) follow the steps outlined in the receiver instructions.
Applications
The GLR4330812R, GLR4330824R receiver's eight relay outputs can be set to eight different modes which allows it to be used in many diverse applications such as security, industrial machine monitoring, crane control, level monitoring, multiple 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.
Case
The GLR4330812R, GLR4330824R can be supplied without a case, this allows the receiver to be integrated according to your needs.
The C160 case (weather proof) can be used to enclose the GLR4330812R, GLR4330824R receiver. The receiver with a case is known as a GLR4330812RE, GLR4330824RE.
