ACURE OPTICS TRAVERSE can be controlled with Sky-Watcher(R) SynScanPro application.<\/p>\n\n\n\n

I checked communication between SynScanApp and Traverse, but there were many commands start with “:X”. “X” command is not yet on the document “Manual: Sky-Watcher Motor Controller Command Set<\/a>“.
Therefore I can not control Traverse with what I did for AZ-GTi.<\/strong>
<\/p>\n\n\n\n

<\/p>\n\n\n\n

Moving Traverse’s motors is easy.<\/h2>\n\n\n\n

However, moving Traverse’s motor is really easy.
I analyzed communications for both axis, and every speed steps, and found that command is really simple. <\/p>\n\n\n\n

<\/p>\n\n\n\n

<\/p>\n\n\n\n

Base Number is “12091.5”<\/h2>\n\n\n\n

The value for Sidereal Time speed (x1.0) is 12091.5, probably. x0.5 speed = 6046, x8 speed = 96732.
(I do not know why this number, because I do not know the protocol. However it does work for Traverse)<\/p>\n\n\n\n

<\/p>\n\n\n\n

Command to set Motor Speed<\/h2>\n\n\n\n

The command to set motor speed is the format like following 21 text format.
:X1020000000000002F3C<\/strong>
(and CR code to finish commands after this)
Devide the format part by part.<\/p>\n\n\n\n

:X<\/td>1<\/strong><\/td>02<\/td>0000000000002F3C<\/strong><\/td><\/tr>
“X”tended?<\/td>RA\/Horizontal Axis=1<\/strong>
DEC\/Vertical Axis=2<\/strong><\/td>		Command to set speed?<\/td>Speed Value<\/strong><\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

Command is “:X”, followed by Axis identifier “1” or “2”.
Then “02” must be extended command to set motor Speed.
Motor speed is 64 bit integer value in HEX format.
No check-sum.

For positive speed values, “Up” or “Right” button in SynScanApp, Speed value is following.<\/p>\n\n\n\n

For negative speed value, “Down” or “Left” buttons in SynScanApp, value is negative value as following.
(in 64 bit Integer in HEX representation)<\/p>\n\n\n\n

And, Motor Stop is simply set 0 <\/strong>in the same format.<\/p>\n\n\n\n

Values above are from each speed step on SynScanApp. You can set other values.
Sor example, Solar speed or Luner speed
\u3000Sidereal day 23:56:04.091 = 86164.091 (sec)
\u3000Solar day 24:00:00.000 = 86400.00 (sec)
\u3000Luner day 23:03:39.014 = 83019.014 (sec)

Solar Speed=12091.5 * 86164.091 \/ 86400.00 = 12058.49\u2252 12058\u21d2 0000000000002F1A<\/strong>
Luner Speed=12091.5 * 83019.014 \/ 86400.00 = 11618.34\u2252 11618 \u21d2 0000000000002D62<\/strong><\/p>\n\n\n\n

<\/p>\n\n\n\n

how to get 64 bit integer HEX representation?<\/h2>\n\n\n\n

If you are using Windows 11, you can use Calculator app.
Set Calculator app in Programmer mode
Click DEC (Decimal) and input decimal value, for example “-12092”, then you see “FFFF FFFF FFFF D0C4” in HEX part.
Click HEX will show HEX value, then copy it by “Ctrl+C”<\/p>\n\n\n\n

Let’s move TRAVERSE<\/h2>\n\n\n\n

Traverse can be connected Wifi(UDP communication), Bluetooth, or USB(Serial communication).
Let’s try with USB.
Connect PC and Traverse with USB-A–USB-C cable. Traverse does work with USB-powered from PC!<\/strong><\/p>\n\n\n\n

I use “TeraTerm”, but any Serial terminal works.
Connecting USB cable, there should be new COM port detected, so connect it. Baud rate does not matter because it is USB-Serial. Make sure “new line” code is CR.<\/p>\n\n\n\n

<\/p>\n\n\n\n

Send “:X10200000000009399F3”. RA axis move at x800 Speed.
Send “:X102FFFFFFFFFF6C660D”. RA axis move at x800 Speed in opposite direction. It automatically decelerate, stop, and accelerate, so you need only set new speed.
Send “:X1020000000000000000”. RA axis stop.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Send “:X20200000000009399F3. DEC axis move at x800 Speed.
Send “:X202FFFFFFFFFF6C660D. DEC axis move at x800 Speed in opposite direction.
Send “:X2020000000000000000. DEC axis stop.<\/p>\n\n\n\n

In conclusion, you can change orange part<\/mark><\/strong>, then you can control Traverse.
:X1<\/mark><\/strong>0200000000009399F3<\/mark><\/strong>
<\/p>\n\n\n\n

This can make Traverse into time-lapse mount, or whatever you like, even not for telescope.<\/p>\n\n\n\n
