Technical Specifications
B.2.1 QPT-20
The QPT-20 positioner, if the temperature drops below -15ºC, activates its
inner heater. Note that if it is intended to use the positioner in an environment
in which the temperature can drop below that temperature, the current can
rise up to 4.5 Amp, so use an appropriate cable able to handle this current.
It is recommended to use AWG28 for the wires of the data cable, and twisted
pair for both TX and RX signals.
To attach the antenna to the positioner, it is necessary a CLAM-1 bracket (Not
included with the positioner).
The pinout of the QPT connector varies with the model.
