RE: Thermo Fischer FHT 6020 Radiation Monitor

["Pearson, Matthew via Tech-talk" <tech-talk at aps.anl.gov>]

Hi Keith,

 

I can’t help with the Thermo Fischer, but in terms of remote RS232 access I can recommend a Moxa secure terminal server. The newest iteration of 1 or 2-port devices are these:

 

https://www.moxa.com/en/products/industrial-edge-connectivity/serial-device-servers/terminal-servers/nport-6100-g2-6200-g2-series

 

Those terminal servers have more features than the more basic device servers, including supporting non-standard baud rates and various network security features. Although there are other more industrial versions that support redundant power supplies and network connections.

 

Then it can operate in TCP/Server mode and you can use streamDevice from a remote Linux server.

 

Cheers,

Matt

Hello,

I have posted a few questions here in recent years asking about Radiation Monitors and had lots of helpful replies.

 

We are finally about to borrow a Thermo Fischer FHT 6020 for evaluation, so I would like to get an example EPICS IOC running.

I believe these monitors are in use or have been tested at ISIS, SLAC and Australia, perhaps elsewhere, so I was wondering who had the most up to date or complete driver they could share with me, please?

I found an asyn driver in SLACs EPICS repository and edl files. Is this my best choice to start with?

 

Does anybody use StreamDevice? (Brendan Chandler at APS mentioned this a few years ago.)

Has anybody created CSS opi files? (I could try running an eld->opi converter as a starting point.)

 

The monitor only seems to have an RS232 port, so I was wondering how different sites connect with this? Perhaps a local IOC with serial port, an RS232->RS485 adapter for more remote connections, or a local terminal server?

We don’t need to daisy chain the monitors. We’ll have dedicated wiring and IOC for each.

 

Any recommendations appreciated.

Thanks.

Keith Baker
