Appendix

Return video signals input to this unit are sent to the 
camera adaptor as HDSDI signals. The camera adaptor 
switches between the return video signal received from 
this unit and the signal received from the camcorder, and 
outputs the signal from the MONI.OUT connector. The 
XDCA-55 sends return video received from this unit to the 
camcorder via its camcorder connection connector 
(50-pin).
As return video signals, this unit accepts HDSDI signals, 
SDSDI signals, and SD analog composite signals. HDSDI 
and SDSDI return video signals are input from the unit’s 

RETURN INPUT SDI connector. SD analog composite 
return video signals are input from the unit’s RETURN 
INPUT VIDEO connector. Use the HDSDI/SDSDI/
VIDEO switch (one of the RETURN INPUT SELECT 
switches) to select which of these signals to use as the 
return video signal (see page 13).

The format of the return video signals that can be input to 
this unit varies as shown in the following table, according 
to the system format settings of this unit and the 
camcorder.

: Yes  –: No

When a return video signal is input to this system, and that 
signal in not synchronized with this system, you can 

synchronize it by using the internal frame synchronizer of 
this unit.

The monitor output from the MONITOR OUT (SDI) 
connector of the XDCA-55 or MONITOR OUT connector 
and MONI.OUT (SDI) connector of the XDCA-53 can be 
switched between return video signals sent from this unit 
and the shooting or playback signals sent from the 
camcorder.

The monitor output from the XDCA-55/53 is switched as 
shown in the following table, according to the settings of 
the MONI. SEL switch and the RET button on the camera 
adaptor.

The TALLY lamp (red) flashes as an alarm if the system 
frequencies of this unit and the camcorder are different.

Even if the TALLY lamp is already lit, it changes to 
flashing if an alarm occurs.

For details about the system frequency of this unit and that 
of the camcorder, see “Setting the System Format” 
(page 19).
