Control of old PTZ cameras via coax

[cjw 0]

I am looking for any assistance regarding replacing a very old Panasonic Mulitplexer WV CU350 with something new to remote control

2 very old ( sorry don't know camera make or model) PTZ cameras that are mounted up 75' in the air at a golf course. Cameras are working fine via coax but 

controller is so old it is falling apart.

Is there a product which could control these unknown  PTZ cameras via coax or am I going to have to replace these 2 working cameras?

Thanks

Hi CJW

 

Did you resolve this?

I recently created a pair of pcb boards based on an arduino  that could take inputs and send them over coax then out put as pelco protocol would that be helpful?
