The GR-12L receiver can control up to 6 servos
With the GRAUPNER HoTT 2.4 GHz technology, the receiver has a new hopping telemetry transmission high-frequency unit with state-of-the-art components and the latest software. Without additional sensor systems, the parameters receiver voltage and temperature, as well as signal strength are transmitted.
The use of up to 75 channels ensures extreme operating reliability and immunity to external interference.
The broad reception voltage range of 3.6 V – 8.4 V (functional to 2.5 V) ensures full functionality even when voltage fluctuates.
Servo connections in the front panel.
Failsafe, hold, OFF, and standard (channel 1 failsafe; all others hold) programmable.
Receiver features programmable via Transmitter or SMART-BOX:
Programmable channel mapping in receiver
5 On-board programmable mixers
Telemetry connection instead of a servo possible on channel 5
SUMD signal available at channel 6
Limitation and reversal of servo travels also possible in receiver
Failsafe, hold, and OFF programmable individually for the servo channels
Warning thresholds programmable for undervoltage, excess temperature, and low temperature
Servo test function
