Latest Rotor 1.1.2 (53)

[VE3DS]

Thomas !
Development continues, very good !!!
I have one question:

When this version starts is opens and AZ and EL window.
I don't use EL so how do I make it not open at startup?
The rotor control is Green Heron RT-21 ...

The beta tester for this model doesn't mentioned this during the testing phase. I have to correct this.

Hi Tom,
just installed Rotor and tested with the SARC MK1 (Easycomm II protocol). I can control azimuth and elevation, but it seems the actual rotator position is not read. When I test with hamlib (rotctl), I can read the actual position with "p". Works also with Gpredict on Mac.

You can check your setup using a Terminal application, i.e. Cool Term.
To read the azimuth the command AZ must be applied, to read both values AZ EL must be used. The commands must be terminated by a line feed character (0x0A)

[Klaus]

Yes, that's all working fine. I can read the position with the "AZ EL 0xa" from a terminal (not AZ without EL) and
I can control the position from the Rotor control window, but the angle displayed is always 0, regardless of the actual rotator position.

Since I use this controller as well, I'm sure it should work.
Can you provide similar screen shots? I've just sent AZ EL 0x0A The return was AZ0.2 EL-0.3 and AZ48.2 EL27.3 The answer must be terminated by a 0x0A

[Klaus]

Tom, the problem is not the serial terminal, when I send AZ EL 0xA I get the current position, like AZ 90.2 EL 10.3, as expected.
The problem is, when I use your rotor program (rotor control window) and turn horizontal direction or grid to 90 deg, then the rotator turns to the desired position, but the display (Azimuth) stays at 0 deg.

We have to confirm:

• There is no space between AZ/EL and the value
• There must be a 0x0A as terminator

Only when the format is correct, the Rotor app can read the values.

[Klaus]

Confirmed.
This is the SARCnet MK1 program routine:
void printAzEl() {
//Print the rotator feedback data in Easycomm II format
SerialPort.print("AZ");
SerialPort.print((az < 0) ? (az + 360) : az, 1);
SerialPort.print(" EL");
SerialPort.print(el, 1);
SerialPort.print("\n");
}
Example:
AZ153.9 EL0.2
