Not sure what you mean, but we run arcnet in bus mode (no central hub), on 75 ohm coax with modified PCI cards using 75ohm terminations - 75ohm coax abounds in TV stations. The advantage of this is we can use existing Video wiring for control systems, and there is no single point of failure. -Steve From mboxrd@z Thu Jan 1 00:00:00 1970 MIME-Version: 1.0 In-Reply-To: <7381af72efb48250b5948a9d12cd3e4d@quintile.net> References: <7381af72efb48250b5948a9d12cd3e4d@quintile.net> Date: Thu, 21 Feb 2013 13:54:27 +0100 Message-ID: From: hiro <23hiro@gmail.com> To: Fans of the OS Plan 9 from Bell Labs <9fans@9fans.net> Content-Type: text/plain; charset=UTF-8 Subject: Re: [9fans] arcnet Topicbox-Message-UUID: 1bc0c4ec-ead8-11e9-9d60-3106f5b1d025 In spite of ARCNET's deterministic operation and historic suitability for real-time environments such as process control, the general availability of switched gigabit Ethernet and Quality of service capabilities in Ethernet switches has all but eliminated ARCNET today.

The cost of maintaining such a system must look prohibitive when compared with off-the-shelf products. And then you need device drivers for every generation of OS that comes along. I'd be at least curious as to how these costs are justified. I mean, I have tens of kilograms of dated network equipment, including the odd lumps of coax cabling, but no ways could I find a practical use for it, much as the community I'm in has no funds for more modern stuff, so we just do without :-( ++L From mboxrd@z Thu Jan 1 00:00:00 1970 Message-ID: To: 9fans@9fans.net Date: Thu, 21 Feb 2013 19:39:37 +0200 From: lucio@proxima.alt.za In-Reply-To: MIME-Version: 1.0 Content-Type: text/plain; charset="US-ASCII" Content-Transfer-Encoding: 7bit Subject: Re: [9fans] arcnet Topicbox-Message-UUID: 1cac6be0-ead8-11e9-9d60-3106f5b1d025 > However, because of its simple, robust nature, ARCNET controllers are > still sold and used in industrial, embedded, and automotive > applications.

Well, at least until usb-optical cables become cheaper than copper, and even then you've got component costs that are more expensive. Moving to ethernet at least opens up the ability to use MODBUS TCP. -jas From mboxrd@z Thu Jan 1 00:00:00 1970 MIME-Version: 1.0 In-Reply-To: <1EEC25CE-C5D7-4BDC-BC34-787F84260EBF@corpus-callosum.com> References: <1c796fa516a34db4215be350fe029d43@ladd.quanstro.net> <1EEC25CE-C5D7-4BDC-BC34-787F84260EBF@corpus-callosum.com> Date: Thu, 21 Feb 2013 14:32:50 -0500 Message-ID: From: Calvin Morrison To: Fans of the OS Plan 9 from Bell Labs <9fans@9fans.net> Content-Type: text/plain; charset=ISO-8859-1 Subject: Re: [9fans] arcnet Topicbox-Message-UUID: 1ceb8456-ead8-11e9-9d60-3106f5b1d025 On 21 February 2013 14:26, Jeff Sickel wrote: > > On Feb 21, 2013, at 12:44 PM, erik quanstrom wrote: > >>>> However, because of its simple, robust nature, ARCNET controllers are >>>> still sold and used in industrial, embedded, and automotive >>>> applications. >>> >>> Sounds positively anachronistic.

ARCNET receives no name recognition, but is frequently the network of choice in embedded applications. It is hidden from the user, but with over 22 million ARCNET nodes sold gives credibility that ARCNET is indeed popular.

Every day users have no idea what unix servers are, but the internet runs on it. Apparently ARCNET used so much, but we never even hear about it! The silent hero...

I'd be at least > curious as to how these costs are justified. not really. contemporary controls, who manufacture the pci arcnet cards supply the drivers for windows. we have drivers for the com20020 NIC for our embedded os, and the chips a as cheap as... well, old chips. our bridge and cards are just a different software on a fairly standard modular card which fits in our 3u rack system. if anyone wants detail contact me off-list, this is already creating too muc= h noise. my real reason for asking was to gauge interest in a plan9 arcnet driver as i am perfectly placed to write one, but it seems there is no interest at a= ll. this is a problem thought, i have plenty else to do :-) > I mean, I have tens of kilograms of dated network equipment, including > the odd lumps of coax cabling, but no ways could I find a practical > use for it, much as the community I'm in has no funds for more modern > stuff, so we just do without :-( >=20 > ++L >=20
