Replace a RS485 joystick with VI to control a PTZ camera

[Hadi.alaee]

Hello all,

I'm new in LabView and would love to get some advice. I have a PTZ camera (pan tilt zoom) which is controlled by a joystick via RS485. What is the best way to start this project to write a VI and control the camera instead of using the joystick?

The PTZ cameras supports PelcoD protocol @ Baudrate of 2400

I have ordered a serial (RS485) to USB converter but not sure how to proceed. Is there a tutorial I can follow?

Thanks

Hadi

Well I'd start with this tutorial I found and go from there.  If you have a problem translating what the tutorial says to LabVIEW then we can give more precise answers.

I typed "Pelco D Tutorial" into Google and found some hits.  It looks like if you know the Pan, Tilt, and Zoom, you should easily be able to generate the string to send to your RS485 port.  Be sure you have the VISA driver installed -- you should be able to use LabVIEW's VISA functions to carry out the PTZ protocol.
