AJA RH10UC SD to HD Upconverter User Manual
Looping Reference
The RH10UC cell group of 9 BNCs contains two BNCs that can be used for a looping
reference connection. If this method is used, then the reference select setting on the
RH10UC should be set to “LOOP” and the TERMINATION setting should be set to “OFF” (no
termination). Optionally, if you're using only one of the looping reference BNCs, then the
TERMINATION setting should be set to “ON.”
Frame Reference
Alternatively, the RH10UC installed in a FR1 or FR2 frame can use the frame's frame
reference input BNC connector, which feeds an external reference video signal to all
modules installed in the frame. How the signal is distributed differs for the FR1 and FR2
frames. Additionally, individual modules can usually be strapped as to whether external
reference is distributed from the frame or directly to BNCs on the module's corresponding
cell group (the 9 BNCs on the rear panel).
FR1 Frame:
the external reference signal is distributed passively to all frame modules. If
you wish to use the frame reference, the RH10UC should have “FRAME” reference selected
on the module strapping, and one and only one card in the frame should have
“TERMINATION” set to “ON.” All other cards in the frame should have TERMINATION set to
“OFF.”
FR2 Frame:
the external reference signal is distributed by an in-frame distribution amplifier
to all frame modules. This system terminates the Frame Reference input BNC and buffers
the signal to all slots. If using frame reference, the RH10UC installed in the FR2 frame should
have “FRAME” set for reference select, and all cards should have TERMINATION set to “OFF.”
