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
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
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 that 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.
