Experimental Physics and
Industrial Control System

Hi

We are happy with MOXA Nport so far.
NPort 5250A with 2 channels ; and NPort IA5450AI with 4 channels is more industrialized.
Both implement a lot of communication modes and features.

Předmět: terminal server/serial server/console management switch        recommendations?

Hi all,

we have a number of serial line devices connected to a number
of IOCs (at 2 telescopes) examples are Lakeshore, Omega DP1s,
WXTs, Edwards gauges. Of old we are/were using Emulex terminal
servers but these things are getting up there in the years and
we lost a few already and had to replace them and we expect more
of them to go.

We have a few WTI CMS console management switches of an older
generation that we use to access computer consoles but I'm
not sure we currently have any measuring devices attached to
them. They work well with computers, including IOCs, once they
are set up to not use ^X as their disconnect character.

More recently we got some of these of a newer generation and we
have problems with them. One of the problems I have seen is that
even after configuring all ports to not have ^X as their disconnect
character they'll still send out ^Xs, and another problem that we
have a lot more frequently is that they don't drop the old connections
when one reboots an IOC. Currently the fastest way to reboot an IOC
is to halt it, manually disconnect all the serial ports and then
boot.

What are other people using, and would you recommend what you're
using or don't you?

Thanks,
Maren
