MDAQ series overview MDAQ Series overview Address settings If you use DEWE-ORION-16xx cards, each MDAQ Module is controlled directly via the RS-485 interface of the associated card. When using DEWE-ORION-32xx cards each card controls and converts two MDAQ modules. Set all address selectors to 0. An additional EPAD module has to be connected to the first MDAQ Module. - Page 15 A/D converter card module address PCB for CH 240 to CH 255 cross wiring Optional EPAD Modules For special wiring see DEWE-xxxx systems manual appendix B3.

Page 16: Mdaq Channel Addressing
MDAQ series overview MDAQ Series overview MDAQ channel addressing Each MDAQ-V-xx module has 16 analog input channels, which can be independent configured. Since only the base address of the MDAQ-V-xx is changeable the access to the input channel configuration is in the range between (Module address x 16) to (Module address x 16) +15. -
