Hi all, Quick question: Does the 2x rs232 interface ports on a 5500PC act in the same manner as the PAA rs232 ports? I want to use it to control AV and need to control 3 devices all up. I already have a PAC unit and was going to buy another to control the third device but I remembered about these little ports. If this is possible, is it the same as initializing a port on the PAC unit via logic? Cheers guys, Dave
