Selectable speeds
range up to 256 kbps.
Your choice of
interfaces in desktop
or rackmount card
models.
Built-in BERT supports
.54 loop diagnostics.
Includes conditioned
diphase modulation.
Runs in full or
half-duplex mode.
S
end data at speeds up to
256 kbps on twisted-pair wire
over long distances with the
LDM-MR256. It supports
transmission distances of up to
3 miles ( .8 km) on 19 AWG wire
or 2 miles (3.2 km) on 2 AWG
wire at top speed. Longer
distances are possible at slower
speeds.
A built-in Bit Error Rate Tester
(BERT) tests both the line drivers
and the line.
As a bonus, the line driver
includes V.5 diagnostic
capabilities. You can perform
local and remote loopback tests
Send data at high speeds over long
distances with these line drivers.

or via control signals from the
interface connector.
With the LDM-MR256 your
data is safe, too, thanks to
conditioned diphase modulation.
This feature provides background
noise immunity, gives you efficient
data transmission and reception,
and eliminates normal line
distortion.
NOTE: These line drivers must be
used in pairs.
