SRA6802N can automatically switch between 525 and 625 line standards.
The SRA6802N supports 2 channels of SDI inputs, and each input corresponds to 4 channels of SDI
outputs. The module can be installed in 6800 series frame.
Features
The SRA6802N offers the following features:
two channels unbalanced inputs
Eight unbalanced outputs
Reclocking
300m of Belden 8281 auto equalizing
Hot-swappable module
SNMP control
FCC Caution:
Any Changes or modifications not expressly approved by the party responsible for compliance could
void the user's authority to operate the equipment.
This device complies with part 15 of the FCC Rules.
Operation is subject to the following two conditions: (1) This device may not cause harmful interference,
and (2) this device must accept any interference received, including interference that may cause
undesired operation.
Note: This equipment has been tested and found to comply with the limits for a Class B digital device,
pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against
harmful interference in a residential installation. This equipment generates uses and can radiate radio
frequency energy and, if not installed and used in accordance with the instructions, may cause harmful
interference to radio communications. However, there is no guarantee that interference will not occur in
a particular installation. If this equipment does cause harmful interference to radio or television
reception, which can be determined by turning the equipment off and on, the user is encouraged to try to
correct the interference by one or more of the following measures:
