HI MY CHURCH JUST BOUGHT A RM32AI AND CS18AI. I AM TRYING TO LINK BOTH THEM TOGETHER WITH OUT USING AN AVB SWITCH. THE MANUEL SAYS THAT BOTH OF THEM CAN BE CONNECTED STRAIGHT USING THE CAT6 PROVIDED. I HAVE DONE ALL THE FIRMWARE UPDATES AND THIS STILL WONT CONNECT. ALSO THE TOUCH SCREEN IS NOT 100% RESPONSIVE.
