I'm attempting to integrate several existing cameras controlled by a Panasonic WJ-FS616 into my new Verint system. Currently the PTZ function control is via up-the-coax. Is there a device that will convert RS232 or RS422 serial from the IP encoder to Panasonic up-the-coax control signals? I'm attempting to integrate these cameras into a Verint ST1708e-t-as IP encoder.

The Verint encoder supports the following protocols:
American Dynamics
CoVi EVQ-1000
Honeywell KDG
Kalatel
Panasonic
Passthrough
Pelco D
Pelco Matrix
Pelco P
Phillips-Bosch
Vicon Surveyor 2000

Thanks-in-advance for any ideas.

UPDATE: I found a link for PelikanCam Coaxial converters which looks like it should do the job.

Anyone have experience with their gear?

You need the Panasonic WJ-NT304 or WJ-NT314 encoders. They will provide UTC control and provide an MPEG4 and MJPEG stream.

The 304 has no VMD or analyitcs built in. If you need VMD then the 314 is what you need.
