Experimental Physics and
Industrial Control System

Hi Martin,

I played with Moxa DA662(2 more Ethernet ports than DA661) for a while and made it work with base(3.14.10) + asyn(4.10) + StreamDevice(2.4). The cross compiler(linux-xscale_be) source code is from Moxa, but we rebuilt it. The whole cross compiling process takes some efforts. I can send you the static cross-complied executable(base, asyn and stream all included) if you want.

My application is to monitor 1-wire temperature sensors (~20K) for NSLS-2. We need 90 Moxa DA662, that's a big number. For better system maintenance and software development, I'm going to abandon Moxa DA-662 and changing to use 5 powerful and stable servers(multiple cpu cores) to handle all 1-wire stuff. Another reason I don't like Moxa DA66x is that the Linux/Debian inside Moxa has limited tools/commands so that it's painful to use.

Hope you make a good decision.

Yong

Hi all,
we are thinking about running IOCs for RS232 devices on ARM based data
aquisition computers from MOXA (DA-661):
http://store.moxa.com/j2bc_ext/doc/prodbase/M20090309140/DA-660-
I_Series.pdf

Can someone who already works with similar devices tell us if this
should work
with base + asyn + streamDevice? What tool-chain did you use for cross
compiling? Did it work smoothly? What are your experiences regarding
time
effort for cross compiling? - Of course setting up a standard Linux PC
together
with a simple device server does the same job. But fewer devices/PCs
means
less trouble...

best regards

Martin
