I have tried to configure a big system with HD configurator on the web with no luck. Based on literature you can have up to 96 inputs and outputs on the system. Configurator allows you to have up to 8 192 I/Os on a big system. However can you add 8 ADC channel cards (which would make it a 128 channel system)? In other words what is the MAXIMUM Analog Inputs allowed per system. Is the same with adding 192 ADC cards or just another 192? Thanks
