deal for local data transfers,
these SMEs support speeds
from 32 Kbps to 144 Kbps at a
distance of up to 300 feet
(91 m) over twisted-pair
cable.
Protocol independent, the
SMEs pass all required data,
clocking and control signals
between the two DTEs. The
Cards can be configured to
Internal, External, or Receive
loopback clocking, too.
LEDs on the front panel
help you monitor data status.
In addition, the SMEs are
FCC approved (Part 15 Class
A).
NOTE: The SMEs are
compatible with the V.35 Sync
Modem Eliminator (ME109A).
