Hi, does anyone have any information on COP-01 protocol??? I'm currently working on a project to control a PTZ camera directly from my p.c. via its serial port. The camera system has COP-01 protocol embedded within its microcontroller, communication is via RS458 at 9600 baud/s. I have been told that Pelco D is the equivalent to COP-01, but my attempts to drive the camera using Pelco D have been entirely unsuccessful!!

All help is most welcome, Tim

Hi The COP-01 protocol was used some time ago and has mostly disappeared now. Some of our controllers still support this protocol. Look here for details http://www.copsecurity.co.uk/product_detai...oduct=15-AU40ES

We are trade only but if this is what you need I am sure someone on the forum would act as a go between.

Also can you let me know the model number of the camera you are trying to control so I can check the compatibility?

Hi Chris, thanks for your reply.

I'm new to security devices so please forgive me if my technical jargon is not what it should be. The actual camera is manufactured by Sony (model no. FCB-EX480BP) which is mounted onto a motorised base, allowing pan and tilt movement.

I can send serial data packets to the camera via a RS458 converter, but cannot make it respond to any command. (Have verified the integrity of sent data to the microcontroller's RS458 transceiver ) It is possible the microcontroller board is at fault, however it does perform a 'power on' self test routine, which suggests everything is working perfectly. So far I have only sent commands using pelco D protocol (having been told this is identical to COP-01...I have my doubts!! ) Ideally I need information on COP-01 protocol at 'bit' level so that I can incorporate it into my software. Regards, Tim

I can ask the factory in Taiwan if they have any information available, this may take several days to get an answer, but I will post here if I get an answer.

Where did you buy the camera from, the FCB480BP id the Sony camera module part number, the motorised base is the bit that has the communication electronics. Do you have a part number for this.

You should also check that the camera had the correct ID setup as well as the correct baud rate.

could also try the comms polarity and termination link too 'allo chris!

Hi,

well the unit was bought second hand, I thought the base mechanics were nicely manufactured and could be given a new lease of life with a new camera and drivers for the stepper motors. The camera looked completely unserviceable being covered in dirt and corrosion. I was surprised to find it still functioned and had quite a nice specification. It would be a shame to not to make use of this camera. Unfortunately there are no other identifying marks either on the PCB's or the mechanics. The camera does give an 'on screen display' indicating protocol, baud rate and address (ie 01) and thats it. Have tried sending the address id in first byte using hex 00 and then 01.....no joy. But without the prot0col format its like whistling in the wind....

Have worked out, that if the data packet is only 8 bytes long (some protocols are 11 bytes) and I leave 1 sec interval between each command to allow the unit time to respond. Then it will take 5,849,424,173.5 centuries to try every possible combination, worst that I thought

Alan.....thanks for your suggestion will change the polarity this evening and give it a try....currently terminated into 120R will also try without resistor...but received waveform looks perfect on my scope, but you never know it could well start working......

Ok I have the protocol from Taiwan the document is a PDF so if you PM me your email address I will send it to you.

I am not sure it will fix your problem but good luck
