Note: Some of the components vary between
the adapters that I have here. The most notable differences are at U12,
U15 and RL1. Some of my adapters have Aromat relays instead of Omron ones.
The RAM at U12 and U15 has a few different makers.
Various little unlabeled squares in the outline above are transformers
and similar parts.
This adapter seems to be on a par with the IBM LANstreamer.
Both adapters offer at least 40Mb/sec streaming (if your system supports
it) and busmastering technology. However, the Smart Ringnode does have
some advantages that make it better in some environments. More OSes have
built in drivers and this adapter is known to work in lower end systems
where the IBM streamer offerings may not work. This adapter also isn't
affected by the nasty Windows NT bug that prevents IBM Streamer family
adapters from working until an NT service pack is applied to fix the problem.
Also supported (if you use it) is auto-detection of ring speed. You
can also manually force the adapter to a given ring speed.
For me, these Smart Ringnode adapters have also been much easier to
find than the IBM Streamer adapters. I have only a few Streamers, but at
least six Smart Ringnodes.
Oh, and the red plastic tabs sure do make for an adapter that gets your

I/O Location & Interrupt Level
Up to eight MC Ringnodes may be installed. Each Ringnode
must use a different I/O Location. It is recommended that each adapter
also uses a different Interrupt Level, although it is allowable for adapters
to share an Interrupt Level if necessary.

conflict with another adapter.

Streaming Enabled permits host bus data transfer rates
up to 40 MBytes/s in machines which support
this option. Streaming Disabled permits host bus data transfer rates up
to 20 MBytes/s.
With Fair mode selected, the MC Ringnode enters an
inactive state when it releases the bus. The system can service any
other arbitrating devices in order of priority before the Node requests
the bus again. In Unfair mode, the Node will immediately re-request the
bus after releasing it.

You must use the same ring speed as the ring you are connecting
to. Incorrect ring operation will result from selecting the wrong ring
