Does anyone know how to use a DEMPR? Does it internally terminate each thinwire
segment or not? I.e., do you run the end of the trunk directly into the DEMPR
or do you T it like every other device on the segment? Do you need to enable/
disable the thickwire uplink port (how?) or is it automatic? What does the
button marked with a T in the circle do? What do the indicator lights mean?
What happens if the DEMPR is powered down, do the segments simply partition with
each segment remaining good by itself, or do the segments themselves become
unusable?

Auto
What does the button marked with a T in the circle do?
Resets the logic; we had them hang periodically & segment goes dead.
What do the indicator lights mean?
Blink to traffic/solid hang as I recall.

Don't recall

You should run the trunk directly into the DEMPR.

If a segment becomes unterminated, the DEMPR will isolate it
automatically and turn on the indicator light. If the light is off, the
segment is fine. Unused ports will have the indicator on.
You should check this, but I think ;
* The AUI uplink port does not need to be manually enabled
* The T button will retest all isolated segments and reenable them if
they test OK.
* If the DEMPR is powered down, the segments are isolated but usable.
