Dreadnaught trigger - HELP - please

I am using a Dreadnaught I, and need to remotely turn in on and off. The problem is that I am not using other Theta gear, and the trigger operates on a momentary 5-12V pulse rather that a continuous 5-12V like most other trigger operated devices.

Has anyone come up with an elegant solution for this?

I thought I was being real trick by building an IR switcher from Ramsey electronics [the ICI1 - http://www.ramseyelectronics.com/cgi-bin/commerce.exe?preadd=action&key=ICI1C] that operates four relays via IR remote signal. With this you can choose toggle operation or momentary, so I have options. This switcher works great, but for some reason the amp won't change in/out of standby when using it. I successfully use it to turn on and off a 7” lcd monitor that is in my equipment closet though, so if it doesn’t work out for the Dreadnaught, it isn’t a total waist.

I have had success turning it on and off with a simple wall wart, and plugging it into the other end of the trigger cable that is plugged into the Dreadnaught. But this is not a very nice solution, and certainly one that my wife won't reliably be able to do.

Please help. Thanks.
