Description
The GLT2708NC/TEX16 combo transmitter is used with the GLR2708/REX16 to have a 16-channel remote control.
The GLT2708NC/TEX16 microcontroller has a built-in channelised code programming system. Channelised code programming programs all the channels, from the sixteen channel receiver, to the sixteen channel transmitter. That is, channel one on the transmitter activates channel one on the receiver and alternatively. To channelise code program a sixteen channel transmitter read the GLR2708/REX16 receiver setup instructions.
The transmitter can be channelised code programmed without power connected.
Operating Distance
An operating distance (in conjunction with the GLR2708/REX16 receiver) of 350 metres is possible. The operating distance depends upon the receiver antenna and location. An independent test revealed the following ranges:
Range (Metres) |
Receiver Antenna |
Receiver Type |
50 |
250 mm Long Wire |
GLR2708/REX16 |
200 |
1000 mm Long Wire |
GLR2708/REX16 |
350 |
ANT27M |
GLR2708/REX16 |
Range tests were done in an open area test site with line-of-sight operation and the receiver antenna wire was fixed vertically, away from any metal objects.
Case
The GLT2708NC/TEX16 is supplied without a case. This allows the transmitter to be integrated according to your needs.
