So I found my answer, am posting in case anyone else has a similiar question.
The connectors on the back of the Rowlands are actually not for remote triggers they are most likely for a connection to a rowland preamp so the preamp can turn the amp on and off. A temporary short of pin 1 and 2 will turn the amp on or off as the front panel switch would. Pin 4 and 5 will illuminate the light on the front panel. Pin 3 is a ground. I was wrong in my original post it actually has only 5 pins not 7 as I originally wrote.
