Reference Sync
There are three “looped” sets of BNC connectors labeled "VIDEO REF 1", “VIDEO REF 2”, and
“AES REF”. These are "looping" inputs for sync referencing. Connect either composite sync or
video with sync to either set of BNCs. If desired, use the second BNC in the set to loop the signal
to another device. If the loop is not used, terminate the second BNC with 75 ohms.
The set of sync connectors labeled “VIDEO REF 2” and “AES Ref” are for future use and
are not connected.
If no sync is available, the routing switcher will switch at a random point rather than during the
vertical interval of the reference signal.
Note:
Reference sync need only be connected to the “Master” frame. The “Master” frame is the frame where the
processor is installed in a multi-frame system.
Input Equalizers
The Ponderosa series routers have the ability to adjust to the input’s cable length. The factory
default settings for the input equalizers are “on”. However, they can be manually set using the
TyLinx Pro configuration and control software.
In the 'ON' mode: The input equalizer is enabled and the routing switcher will automatically
adjust to the cable length connected to the input.
In the 'OFF' mode: The input equalizer is bypassed, and the routing switcher will not do any
cable equalization.
Output Reclocking
Ponderosa provides intelligent reclocking with a microprocessor that analyzes the data rate of
incoming signals. If the rates are within range of standard 270Mbps or 3Gbps data rates,
Ponderosa will optimize the signal to its target rate. If the data rate of incoming signal is outside
typical 270Mbps or 3Gbps data rates, like MPEG-2, Ponderosa will allow the signal to pass
without interruption.
The factory default settings for the reclockers are automatic. However the reclockers can be
manually set using the Sierra Video TyLinx Pro software.
