OVERVIEW
The 7703BPX-DC-RF is a wide band 2x1 RF protection switch that provides auto-changeover
functionality to provide bypass protection of RF signal from 10MHz to 2250MHz and for DC LNB bias.
Manual control or automation control via the GPI port is also provided. In the auto-changeover
application, 7703BPX-DC-RF can be configured to have a
Main
input and a
Standby
input. In this
configuration, it will automatically switch to the
Standby
input when the
Main
input power is weak or
lost. It can also be set to auto-switch back to the
Main
source when this signal is re-established. This is
a latching switch which maintains switch state on loss of power.
The 7703BPX-DC-RF has integrated
Vista
LINK
®
technology for remote control and monitoring
capability via SNMP. This provides the user with the ability to locally or remotely configure and monitor
parameters such as module status, selected input, power level and switching threshold.
The 7703BPX-DC-RF occupies one card slot and can be housed in either a 1RU frame, which will hold
up to three modules, or a 3RU frame, which will hold up to 15 modules.
