This option requires many ~100m long HV cables but removes the requirement of radiation hard boards. That solution simplifies the control system of the HV regulation cards (called HVRemote). It consists of a Detector Control System (DCS) node linked to 256 HVRemote boards through a tree of Ethernet connections. Each HVRemote includes a smart Ethernet transceiver for converting data and commands from the DCS into serial peripheral interface (SPI) signals routed to SPI-capable devices in the HVRemote. The DCS connection to the transceiver and the control of some SPI-capable devices via Ethernet has been tested successfully. It was fabricated a test board (HVRemote-ctrl) with the interfacing sub-system of the HVRemote. It is being tested through SPI-interfaces and several devices were already validated. A next version adds a few more ADC/DAC devices for checking their suitability for the final design.
