Integrating American Dynamics and Pelco

[Sejjiboy 0]

I was approached to help solve an issue regarding the integration between an American Dynamics Intellex DVMS and three Pelco Spectra IV PTZ cameras. They can get video, but cannot get any PTZ control via the software on the DVMS. Currently they have the PTZ set to D Protocol, connected to the DVMS via the UTP Data connection, and D Protocol firmware installed on the DVMS. From my understandings of these types of systems, this would be like trying to drive a car without a steering wheel. Doesn't there have to be some kind of RS422 connection between the devices? The DVMS doesn't have any 422 connections on it. The solution that first popped into my head was to add a USB-422 converter between the DVMS(USB) and the PTZ(422). If we were to throw in three USB-422 converters, could that potentially correct the error or are there more issues that would need to be addressed?

 

Thanks,

I'm not sure it'll work.

 

You can bring the pelco into a matrix then hook that into the intellex using a rs232 connection. other option is to use a USB module from AD that converts to sensornet, but I'm not sure the pelco PTZ does sensornet.

 

The intellex really has limited options from my experience... they never really considered PTZs outside of the american dynamics realm.

Hmm yeah we seem to be having issues ><

 

From what I've been told, the Pelco PTZ's will not run on sensornet.

 

So a matrix and a rs232 connection, hmm, time to look into that one.

 

Thanks for a reply.

Try Building Block Video for sersornet to pelco protocol converter

Try Building Block Video for sersornet to pelco protocol converter

 

Get a USB-422 converter.

You can use the one from B&B Electronics (USOPTL4)

or the Kantech device (USB-485)

 

the DVR needs to be runnign 4.2 or above and you can use the customer handler from the AD website.

OK so, we couldn't get it working. We picked up a PTZ controller.

 

Now we have a KBD300a going direct D to the Spectra IV.

We have the baud rates, the protocols, and the wires all hooked up properly.

3 different techs from tech support confirmed this.

Still nothing..

 

We assumed something wrong with the camera?

Tested with a second camera.

Still nothing..

 

I would assume a Pelco controller properly hooked up to a Pelco PTZ would work wouldn't you?

It's bound to be some minor oversight.

Let's do a systematic diagnosis of the problem.

 

(1) Have you established that the keyboard KBD300A does work by hooking it up to a separate Pelco dome?

 

if OK then:

(2) Check the RS485 wiring.

 

then:

(3) Check the wall block terminal to see if it's wired correctly.

 

Were the PTZs working recently with another controller? i.e. What is the history of those PTZs? How were they controlled?

Have you checked the switch settings inside the back board? They may have been set for an entirely different controller.

Ok.. Well we seem to have discovered the problem..

 

Originally they had the cameras hooked up with TXB-AD translator boards. Once we decided they weren't needed they simply removed them. Apparently there is some kind of PCB that has to be inserted into that socket to complete the circuit? Those were discarded during the initial install..

 

Ugh..

Yep, shorting plug, Pelco part# PA05-0036-00D0. Time Lapse Supply has them.

I believe that, Like valboosky said, the best option is the USB-485 from Kantech. Install the handlers from AD's website, then you will daisy chain the cameras.
