Recommendations for Ethernet to serial adapters

[tst]

Cross post to LAVA - http://lavag.org/topic/12120-recommendations-for-ethernet-to-serial-adapters/

I'm looking for recommendations for Ethernet to serial adapters (also known as device servers) which have 2 or 4 RS-232 ports. We don't need super performance or anything like that, just something that will work decently and not break down. If you have worked with a product you liked (or disliked) that's what I want to hear.

The only one with this number of ports we used was from Advantech and our impression wasn't good. I've used ones from Tibbo as well and I have nothing but good words about those (in case you ever need such a device), but unfortunately, the relevant models only have one serial port.

Hello tst:

I have had good experiences with various hardware from Black Box, but have not used their device servers.

Here is a link to 1,2, and 4 port units:

Currently, I'm using a B&B Electronics ESP-414, which works well, and is reliable, but I've had a small issue with how it packages data running with 100Hz sensors attached.  http://www.bb-elec.com/product_family.asp?familyid=643

See this thread for more info on its short-comings:

I've also used MOXA in the past with good success, but it was 5 or so years ago and for an application w/ low data rates.

Good luck w/ your search.

Thanks for the replies. I'll add those to the list and try to remember to report back after we selected something and see that it actually works.

So this project was somewhat delayed, but eventually it was executed and I can say that we used the EDS4100 from Lantronix, which seems to work well so far. We had some issues, but those had to do with some of the devices we connected to it, which required some special cables.

I have succesfully used Advantech but currently I am using a brand callled ORing (IDS-5012), which I am having problem with. Anyone have used this brand succesfully?

I would suggest contacting their tech support. Posting here is not very likely to get you a good answer.
