EPICS driver for the Ludlum M375 radiation monitoring devices.
The driver is an EPICS Asyn Port driver.
From my EPICS point of view, I think the Ludlums are a little slow to connect. They are TCP/IP clients, and the EPICS IOC is the TCP/IP server - see below. The connection time can sometimes take 2 or 3 minutes. They device can be configured using a browser.
Our controllers move around (as they go away for calibration and replaced by spares), so rather than reconfigure the device for a particular new physical location or reconfiguring the EPICS IOC, on the EPICS IOC host, I run a number TCP client-to-client (i.e. Ludlum client, EPICS IOC client) connection python scripts, configured by a simple text config file. This also avoids the need to restart the EPICS IOC. This seems to work well for us.
The EPICS driver itself is unaware of this and could equally use an ASYN port configured as a TCP/IP server.
