The DX-7501 is a data transceiver designed to transmit and receive digital
current loop signals in a wide range of diverse applications. The unit is
designed to operate in simplex or full duplex modes. The DX-7501 can easily
be user configured for active or passive 20, 30, or 60 mA current loop
operation. The DX-7501 will operate continuously at all data rates from DC
to 115.2 Kb/sec. For analog current loop signals see the
INST/INSR-2001 and
INST/INSR-3001.
Both multi-mode and single-mode 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. |
