The 8947RDA-D is a dual SD/HD re-clocking
distribution amplifier, with automatic format
detection. It provides four to eight reclocked
outputs for each of its two inputs and can
equalize up to 125 meters of Belden 1694A
cable for HD-SDI. It can be used to distribute
either HD-SDI or SD-SDI making it ideal for
mixed format applications or installations where
an upgrade is planned.
All parameters can be configured directly
from the card edge or via standard HTML
Web browser if a network interface module
has been installed. The module operation and
configuration as well as the signal presence
and format can be monitored using industry
standard SNMP protocol via the network
interface module.
