Greetings all,

recently been having a problem with our slide machine a Kodak Ektapro coming on all by its self! We are running panalogic Ca2000 automation , the slide machine is connected via a serial plug , all the basics seem to be in order.
(could It have seen I Robot and has been corrupted!)

Any thoughts on this one ?

Phil

Bad serial cable?

(What was so wrong with automations that switch the power to the outlet to which the slide projector is connected? Seems like a much simpler and cheaper idea than a serial interface....)

Switching the power makes bulb cooldown hard.

I am not unhappy about the way the slide machine is interfaced , this has worked fine in all 3 cinemas until number 3 slide machine has develpoed a mind of its own , I was curious if anyone has experienced this fault and if it can be located to either the slide machine or the panalogic system.

Swap the evil silde machine with another one, then you can see where the problem is. I am not familiar with that solution. What is the pinout for the automation interface cable?

We've had weird things happen with that exact equipment, however it wasn't totally random. Whenever a show was paused (either manually or via a film break routine), restarting it would trigger the mini-disk player to start, which would in turn trigger the slide machine. Perhaps the automation is sending a signal to your slide audio device, which is pulsing the slide machine (but you don't notice the audio device because the sound isn't on that channel).

We never did work out what was causing it, because we rarely pause shows anyway and we only have slides in one house now so it's not an urgent issue for us. I'd be interested in theories though, because it's definitly strange! [Smile]

Had the same problem here In one cinema never tracked down the problem, has not done it for at least 12 months.Thought it may have been the automation (Kinoton EMK1)but wasnt that.Only thing we could put it down to is the power suppply in our area which flickers on the odd ocasion and hasnt done that for some time.Strange that it only the one slide projector which is affected.Dosent matter much as only 2 cinemas now have slides and in the next few months they will go as well.

We have Ektapro's in 6 of our 8 screens, they are all directly connected to a hard wired power point that is always on, the automation is provided via a serial cable. About four of them do the same thing (coming on by themselves). This has been happening for at least 6 months now and was put down to a dodgy power supply within the unit... nothing to do with the automation, or noise on the serial cable.
