1-2 Rear panel description.
1 – USB connector
Enables connection to a PC port for remote operation.
Pin 5 = computer ground
Pin 2 = serial data out (to computer data in)
Pin 3 = serial data in (from computer data out)
2 - Rotator control cable male connector.
Connect the rotator to the controller
3 – AC Main Power male socket (230Vac or 115 Vac)
4 – Fuse holder.
19x5mm, 1.6A fuse is required.
1-3 “D” Controller features.
Warning:
this is a complex controller, make sure you understand before using it.
This controller has several features settable via USB serial port and some of such features are
even settable manually. A four ways dip-switch allows manual selections.
Controller parameters settable in either modes:
Soft start – Soft stop
South stop or North stop
Rotation range 360 or 500
Calibration
Off-set
Controller parameters settable via USB only:
Reverse delay
Preset delay
PWM duty cycles
Rotation range
Optimizer
Rotor chk
Controller display mode settable manually only:
Absolute or relative display mode.
Entering in Absolute mode
The controller uses an ADC which accepts 0-5V voltages. The antenna position voltage readout is
mapped to be inside the 0-5V range. In the absolute mode the display shows directly the rotator
position expressed in absolute degrees: you read values from 0 to 500. In the other operational modes
(north/south-stop) the absolute readings are converted into different angular position numbers, but
only for input/display purposes: internally the program works with absolute angles.
The absolute mode can be only entered turning-on the CBOX with the CW key pressed until the
display shows a blinking “---“ (three minus): now you can release the key and the absolute mode is
entered. You can move the motor using CW and CCW keys between the rotation limits.
To exit from such a mode you must recycle CBOX power (forcing another mode by USB command
isn’t effective).
In the absolute mode the rotor can be only operated by the CW/CCW
The absolute mode is usefull for CBOX calibration (see CALIBRATION paragraph).
It is NOT recommended to turn big antennas which need to be started and stopped softly.
