“twister” 2111 Media Converter 11

BNC Interface
(2111-12-01)
The “twister” 2111-12-01 attaches to thinnet coaxial cable via a standard
BNC connector and supports a maximum segment length of 185 meters.

IMPORTANT: The coaxial cable of a LAN must be properly terminated at
the end of each segment regardless of the device used at the end of each
cable. One end of the two terminators on each segment must be grounded.
