I can help on this one, as I have some of the Sunn lighting products. Sunn was apparently a well known amp made in the late 1960's, see
Fender-Amp.com. It seems that Fender tookoover operations. See this url:
SUNN® Support for some contact info.

There is a specific mention of a similar board at
i Have a lighting board by SUNN
Not to rain on your parade--but:
I have a
PLC 816 in deep storage, but I absolutely hate it. It is a simple 2 scene, no memory type board. It can not do dipless crossfades (like newer units do). As you
fade between scene I & II ALL the lights will all "go down a little" as the
fader approaches the mid
point (50%
level), then they will go back up as the
fader approaches the endpoint--even if new the
cue is at a higher
level. There is no way around that--the lights will always go dim for a moment as you change scenes.
The other drawback of this
system is that it uses a proprietary data signalling format, the "SUNN
protocol". It is similar to, but not exactly
microplex. That means you can only use Sunn
dimmer packs--which are getting hard to find.
I do believe there is a guy on eBay that makes a
protocol converter for Sunn-->LMX (multiplex). And don't even TRY to
plug a
DMX controlled
unit into this system--especially if you have a Sunn
dimmer pack already on the data
line. I am fairly certain the Sunn
protocol sends 12-15vDC down one of the conductors.
Unfortunately, I was unable to find specific info for your
unit. But, I hope this baseline info helps.
