Hi All , Since I purchased the PJ last April I've wanted to use the 12v trigger facility to operate my screen. I tried to use the cheap option from an electronics web site (can't remember the name) but failed. I'm looking to purchase the Beamax 12v trigger box http://www.discounttv.co.uk/product/Beamax_12V_trigger_box.html, has anyone had experience of using this unit? What cable do you use to link the 2 units? Any help will be appreciated. Thanks.
