I have an Equinox ELS-48 terminal server, with (originally) 24
MMJ ports. It uses seperate CPU and port-boards. BNC type
ethernet connector. Has room for another port card, if you can
However, some of the lines (1-4?) are disabled due to a lightning
strike. I got it mostly working again by removing the remains of
the dead interface chip, and several fried filter caps. Never used it
for anything after that "fix", but it tested Ok.
The filter caps should probably be replaced (2 small, 2 larger),
not sure of original value of the larger (value was burnt off).
The interface chip is probably not easily fixed. It charred the
circuit board, and the traces under it (*both* sides of the circuit
board, and probably the internal layers). Several traces are gone
(melted away completely). I think it only knocks out <= 4 lines.
$10 + shipping (from 83401)
Extra is for shipping materials, plus enough pepsi to power me
up enough to reach my UPS shipper.
