Description
The GLR27VOID lets the user enable/disable up to 99 transmitters with each transmitter having a different code. Programming the transmitter with different two-digit numbers does this.
User can program an unlimited amount of transmitters with the same code. For example, a family of four could have four transmitters with the same code. This would only use up one of the two-digit numbers. To program a transmitter with the same code you need to give each transmitter the same two-digit number.
Programming the GLR27VOID
Step 1: Check to see if power is connected to the receiver.
Step 2: Connect the transmitter to the receiver by inserting the GIGALINK ä cable into the 2.5-mm sockets. This will activate the programming mode and is indicated by the red light (LED), on the transmitter, that must remain “on”.
Step 3: Select, on the receiver, the two digit number you want the transmitter to operate on.
Step 4: Press one of the selected channels on the transmitter for approximately one second, transmitter LED should blink twice to confirm code programming and then switch “off”.
Step 5: Unplug GIGALINK ä cable. The selected channel on the transmitter is ready to be used.
Steps 1 to 4 can be repeated to program another transmitter channel.
Button next to the two digit numbers is used to enable or disable the transmitter that is programmed with the two-digit number. The LED “on” indicates transmitter is enabled and LED “off” indicates the transmitter is disabled.
Transmitter is enabled when red LED is “on”, for its chosen two-digit number.
Do not select 0 0 as the two digit number. Factory testing only.
The one-way dip-switch is used to change the relay output from Monetary to Flip-flop.
