The Liteway DX-7001 is a data transceiver designed to
transmit and receive RS-232, RS-422, RS-485 (2 wire or 4 wire) or TTL
signals in a wide range of diverse applications. The unit is designed to
operate in simplex, full duplex or drop-and-repeat modes and can easily be
user configured for a single protocol or for mixed protocol operation. The
DX-7001 will operate continuously at all data rates from DC to 10 Mb/sec.
Both multimode and single-mode fiber versions are available and installation is
totally adjustment free. In addition, integral indicators are provided to
continuously indicate the presence of data signals as well as the presence
of operating power making system troubleshooting simple.
