RS485 questions

[cocacola 0]

I have a Vista PTZ dome (not windows vista, but brand vista)

I got a rs485 output whit A/B see picture.

 

My old 4channel Avtech recorder has a sub 9 i/o connector.

The manual learn me that pin 10 and 11 are for rs485.

The question is wits wire must i connect to witch pin?

 

And other question, 2400/4800/9600 etc.. I can select all speeds on the dvr and dome those 4800 or 9600 or no divergence noticeable when use.

I plan to use 2400 on the dome and recorder, is this wise?

 

Anyone?

That should be fine. Baud rate shouldn't make a functional difference, as long as controller and camera both use the same rate.

You just use the same rate,that will be OK

Hmmm, up and running, But the ptz movements are not that great whit the AVtech software. i press left and 2 seconds later i go a bit left. Really diverticult to get the camera i the position that i want.

 

Have i made a cable error? or is it just the software that sucks?

Suggestions welcome.

Probably the software. RS485 is usually either go or no-go. If you wired it wrong you would not be able to control the PTZ at all.
