External flash for K10D

I have a very old Vivitar 283 that I used with my old 35mm camera. Is it possible to use this as a remote wireless flash with the K10D as the trigger? If so how?

I cannot find any wireless slaves that appear to be Pentax RF compatable.

Radio transmitter/receiver; pair of/or something like Pocket Wizard. Short cable w/Vivitar 283 plug on one end, mini-phone plug on other.

Camera on/in manual mode.

Yes, those are god options. Does anyone know of a remote slave module that will trigger off the wireless RF already build into the K10?

Pentax sells at least tow external flash units that use this signal.

The Pentax system is optical not RF. Proprietary, as such difficult to reverse-engineer and emulate. Sigma probably has the best shot at accomplishing the task, but has not apparently done so to date.

I do not understand. If the K10 is optical why is there a flash setting for wireless? What does this setting do?

I thought optical indicated that the remote flash slave used the light from another flash to trip the trigger. This could be done by using the onboard flash as the triggering flash. Therefore, there is no need for a wireless setting inside the camera.

You need either the onboard flash or an external flash mounted on the camera (or wired to it via the hotshoe, to use wireless. It's optical, and perhaps IR; part of the pre-flash set-up in P-TTL. It's not Radio Frequency.

In auto or manual mode it's simply an optical slave--like a built in Wein Peanut or similar.

It is 'channeled' in that it can be isolated from simple flashes in proximity or set to a different channel than similar Pentax equipment nearby.
