Hey Guys,

I just started working on an Augmented-Reality project. For this project I have a PTZ-Camera and I can send inquiries for Pan, Tilt, Zoom and so on. The problem I have is that the answer comes packaged in 4 bytes (I am just looking at the Tilt Values right now) and I cannot find a way to reconstruct the actual data.

The Data comes in the following format in an TcpIp-Dat:

90 50 0w 0w 0w 0w 0z 0z 0z 0z FF

(from the documentation found here, search for “CAM_PanTiltPosInq“:

https://ptzoptics.com/wp-content/uploads/2020/08/PTZOptics-VISCA-over-IP-Rev-1_2-8-20.pdf )

In this package, the wwww represents the Pan-Value and the zzzz the Tilt-Value. In Wireshark it looks like this:

90 50 0f 0e 04 0e 00 05 01 00 ff

In the TcpIp-Dat with bytes enabled it looks like this:

80 15 14 04 14 00 05 01 00 255

I have found that if I take the zzzz (Tilt-Values) from Wireshark in this example and run them through a Hexadecimal to Decimal converter, it gives me a number I can work with. In this example “0510” gives me “1296”. How I decipher this number to some kind of degrees is another question for another day, but I think it divides 360° of theoretical movement in 256²=65536 Steps and that’s logic I think I can handle.

I know that if I take the Tilt-Values (the bytes) in TouchDesigner “00 05 01 00” and converted them to normal integers I could use math (first number times 16³, second number times 16² and so on) to get that same number. But I have not found a way to convert the bytes to integers.

My question is, how I can get this conversion from bytes to integers done in Python or other Dats. Any help would be much appreciated! I will append my file, so that you could look at what I have done so far!

Thanks
