Kepping them off when they're starting up

I was wondering if there was a way to start up a fixture on a rig without having it strike it's lamp (I wouldn't be able to get to it to do the hold down "menu" and "enter" button to bypass the homing and striking of the fixture). Here is my situation: I'm doing a show where there is a distro on the ground with a five wire running up to the truss to a small motion labs distro that has (2) DL-1's, (4) Studio Spot 250's and (1) Color Power for my 12 Color Commands on the rig. Since the breakers for each circuit is on the distro in the rig, I can only turn on and off that 5 wire running it from the ground. Well, I know that for a majority of the time I'll be concentrating on my automated lighting and I would prefer not to strike and burn the lamps in the DL-1's when I'll only be working on the other automated lights on that circuit. So I was wondering if I was already sending a "Shutdown" command to the DL-1 when I power up that circuit, will it not even strike the lamp or would it strike then shutdown or ?????? Is there a better way to do this?

    As far as I can tell there is no way to prevent lamp strike on power up for S.Spot 250 or DL-1.

    However you CAN send them lamp-off and shutdown commands from your desk.

    It obviously doesn't matter for the Color Commands, as the lamps only come on when you set a level on their associated dimmer.

    This is one of the many reasons it is not a good idea to put things like your PDs up in the truss;) .

    Any reason the PD can't live with your dimmer rack (I'm assuming that is not in the truss as well).

    At any rate I hope this is an acceptable/usable work-around for you:)

    With the exception of DL.2 there is no way to change the default lamp on behavior of the fixtures.

    The operation is that they will not strike the lamp until they receive a DMX signal. So you can power them up, but if you can unplug the DMX link then they will not strike their lamp.

    If that is not an option, then as was also said you can send a LAMP OFF command over DMX to shut the lamps off.

    Yes, that would also work.

    If you have separate DMX lines coming down from your truss for each fixture type, then you could simply unplug them from your opto-splitter or whatever, so they don't strike or home.:)

    I'll pass it on as a request. I doubt it would make it into the older products, but it may make it into the newer ones.
