A Controller fully controllable via RS232
A short story about this new antenna rotator controller..
After five years of succesfully experience with the previous B and C controller models, that where already
advanced in features and techology, we decided to put togeter in one new controller the greatest features
of both versions.
A last generation's CPU with a new software, allowed us to manufacture a fully computer
programmable/controllable antenna rotator. You can configure it as you need for your antenna system.
It can became a controller for azimuth or elevation rotator or something else.
Having the new CPU an excellent PWM, to have it working with all rotators model than we decided to switch the rotor AC motors to DC motors, easily controllable with a PWM.
It looks like the previous B, but internally it has a new electronic board/circuits with RS232 built inside.
During controller allignement and quality tests, the controller has default configuration, such configuration can be reprogrammed using the "tool software" series supplied.
Guys that don't have PC, can change some controller features using some on board dip switches.
By this re-styling operation we did not got a new product only with greater features, but even a little bit less production cost, so now you can get an improved antenna rotators with a lower price.
"D" controller is available in desk top or 19" rack version.
The front panel and manual commands:
On the front panel are placed: power switch, CW and CCW toggle switches, Preset knob and display.
Something about "preset": It is made by a rotative absolute encoder.
It allows you to choose an antenna direction in the 0-360 degree range, rotating a knob.
As well you turn the preset knob, dispaly will show the wanted heading.
When you will stop to rotate preset's knob, after a short delay time, the rotor will start and will stop when it reach the new choseen heading, while display will show step by step the antenna motion.
The delay time is provided to allow you to change your mind before that rotator start and than you can input a new heading.
While the rotor is running after an input preset command or via RS232 you can stop it just pusching momentarly one toggle switch.
(olny the main features are listed below)
Features programmable manually or via RS232:
South or North Stop
Soft Start-Soft Stop
Calibration and off-set.
Features programmable via RS232 only:
PWM duty cycle
Control boxes are manufactured with the highest-quality components. The circuit is powered via an AC filter and a large transformer that provides the operating voltages for the controller and rotator motor. Two 10A long-life relays energize the rotor motor.
Another feature of the control box circuitry is the special way in which rotation limits are implemented. No limit switches are used in the rotators but the limits are controlled
electronically from within the control box.
This permits travel much greater than 360 degrees.
Each Controller has 70° extra range on the left and right side, for 500° total. If the antenna is in 70° extra range, the display will show it.
The digital display shows the antenna bearing in degrees, true to 1 degree, as the rotor shaft has no play or backslash.
Control boxes and rotators are individually calibrated and checked before shipping.
Maual is composed by three sections, one printed, for all users. Two parts are available as .PDF documents on CD or diskette, enclosed with rotator, for someone that want to play with RS232 and computer.
On the same diskette they will even get the "tool software".
If you are a software expert writer , using such extra infoes you will be able to write a rotator control software by yourself.
