Low Voltage control Applications

Scope

• We will be using low voltage power supplies for DC preamplifiers and SiPM bias voltages, most likely MPV-8008 and MPV-8120 cards from Wiener on Mpod multichannel power supply.
• We expect approximately 8 Mpod crates with about 42 LV cards.
• EPICS driver needs to be identified, or written if it does not exist.

Interface

• The Mpod crate has USB and Ethernet interface. The Ethernet interface utilizes SNMP protocol, using which we in principle can set parameters from Linux prompter without any additional software.
• There is an existing EPICS support for this crates and cards, so most likely we will not need to write the driver for LV power supplies.
• The existing SNMP server on the crate allows us to recognize what devices are in the crate.
• The SNMP protocol allows to turn the power off to the LV cards, but does not allow to reset the controller board or to recycle the power to the crate. Resetting the controller would require an access unless we do not use a remotely controllable power strip.
