DESCRIPTION
The SME-X21 allows two X.21 DTE devices to communicate within
proximity of each other. The SME-X21 transmits data bi-directionally
at data rates up to 2.048Mbps between DTE devices. All clocking
and signal crossover are provided within the SME-X21. The
unit is equipped with two DB-15 female connectors.
The SME-X21 is an excellent choice for interconnecting your
LAN or mainframe equipment. Substantial cost savings are derived
by eliminating the need for analog or digital Modems.
Installation is fast and simple by setting the internal switches
for Clocking and Control (C) to Indicate (I) delay. The SME-X21
has status LED's for each attached DTE device which allows
the user to visually confirm the presence of control signals.
The SME-X21 utilizes state of the art digital CMOS technology
to provide a feature filled product at a very affordable price.
Our Field Programmable Gate Array (FPGA) design has allowed
us to offer this product with a wide selection of user Baud
Rates. This design approach has also reduced the amount of
clock jitter for high speed 2.048Mbps transmissions.
The SME-X21 is housed in a sturdy metal enclosure and operates
on 110/220VAC. Typical MTBF figures are in excess of 100,000
hours of operation.
The SME-X21 has a three year warranty and a 24 hour turnaround
on warranty repairs.
