Send async data across shortand medium-
range distances.
Use existing in-house twisted-pair wiring
to transmit data.
Choose from a variety of data rates—as high
as 115.2 kbps with the highspeed SHM-B.
Some models also available as cards for
rackmounting.
Microdriver 9 can be ordered with surge
protection.
Choose the nonpowered Microdriver 9
for simple installation.
Models for multipoint applications available.
