I have three AV TECH 732E video web servers. I can get them to work fine with Pelco D cameras on RS-485. I select the proper address and select PTZ D camera and all works fine. I did not realize that my third web server was the 732S. They look identical but software is different. I cannot get the ptz cameras to work. The addresses are set but the pulldown menu for the device only shows ptz camera. It doesn't have a selection for PTZ D like the 732E. I get video but no camera movement. Any suggestions would be welcome.

Yes, I have a three 732E servers and one 732S. I ordered all at the same time and didn't notice the one different server. They look identical. Only the software was different. All the PTZ cameras are the same. I'm not sure of the brand but they are a dome camera where the PTZ is RS485. The manual I have gives me a model number of M011-P/T. They work fine on the 732E server when I select the PTZ-D peripheral device. There is no PTZ-D device listed on the 732S. When I use a scope to check the RS485 data, it is clear to see the data is different on the 732S hence my guess was that the PTZ on the 732S is not Pelco D protocol. There is really not much support from the AVTECH site. There is a provision for firmware upgrade on the servers but no place to download if any.
