Just playing with a Fujinon CPT-1A-10DA pan and tilt head, these units
are used in the broadcast TV arena. It may use the same protocol as the
Very little documentation supplied with the product, although appear to
have confirmed that the unit is controlled using RS232.
The manual for a suitable PSU was supplied, so managed to identify power
and RS232 lines. Dismantled the unit to confirm that RS232 feeds pin 13
of a MAX232 (R1IN).
After moving the pan channel (by hand) with power removed, the unit
returns to previous position when 12V is applied; am assuming that the
unit works OK.
This unit was originally configured by BCL (now Kordia ?).
Managed to find a suitable controller (EOP-102J-30E) on eBay for
US$1100; would like to borrow it to do some comms sniffing but that
Finally, spotted that the unit sends a short message from it's RS232
port at power on. Looks like data cells are 200us wide, so maybe a
4800baud comms channel. Need to explore this more.
Have found all manner of P&T protocols, some require an address field
(RS485, or RS232) so that adds a further level of uncertainty/excitement
to the proceedings.
If anyone has experience with such devices, or know where correct
documentation might be acquired, I will be most happy to hear from them.
This is not a commercial project, and hair is being pulled out by the
