The following has proven to work with Debian Jessie running on a SuperMicro SYS-5015A-H (Intel Atom processor without 64-bit support). This guide was written after-the-fact, so some steps may be missing. When configuring the next machine the gaps will be filled. * Fresh install of Debian Jessie (x86) with lightweight desktop environment * Set desired SSH priviliges * (Optional) Add LIGO repositories * Download EPICS-base distribution, Modbus package, and Asyn drivers, install & build (if not pre-built). The (only attempted) combination of EPICS base version 3.15.5 with ASyn 4-32 and ModBus R2-10-1 has been found to work (in combination with base 3.14.12.2_long on the rest of the machines) |

The new uses the Acromag XT series DIN-rail mounted A/D, D/A and BIO moduels. The model numbers are in the format XTYYY1, where "XT" is a static prefix, "YYY" determines the function, and the "1" denotes the ModBus/TCP version of the model. The 1 at the end is important, as the other variations will not interface with CDS through EPICS properly.

HowTo
Configure Acromag XT modules
Initial configuration via USB is required before the units can be used on the network. This requires a USB-to-miniUSB cable, a Microsoft Windows (Version?) (virtual) machine, and the configuration utilities which can be downloaded from the Acromag website (login required). Each model requires a different flavor of the utility to be run. Virtual machines work with USB2.0 ports, but have issues when using USB3.0+ ports. The to-be-configured device needs to be powered by a 12-32V DC voltage source.
