The SME-530 modem eliminator allows two RS-530 DTE devices to communicate within proximity of each other. The SME-530 transmits data bi-directionally at data rates up to 2.048Mbps between DTE devices. All clocking and signal crossover are provided within the SME-530. The unit is equiped with two DB-25 female connectors.

The SME-530 is an excellent choice for interconnecting your LAN or mainframe equipment. Substantial cost savings are derived by eliminating the need for 56/64Kbps CSU's and T1 CSU's.

Installation is fast and simple by setting the internal switches for Clocking, Carrier Operation and RTS to CTS delay. The SME-530 has status LED's for each attached DTE device which allows the user to visually confirm the presence of control signals.

The SME-530 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-530 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-530 has a three year warranty and a 24 hour turnaround on warranty repairs.
