Using a Battery (Option)
The LV 5380 can use batteries if it is equipped with a battery mount. The LV 5380 becomes
very heavy when a battery is attached to it. Be careful to prevent the LV 5380 from falling or
otherwise causing harm.
If the battery weighs more than 1 kg, do not move the LV 5380 with the tripod attached.
Doing so may cause the LV 5380 to warp and malfunction.
The battery mounts are factory options (sold separately). Batteries and chargers are not
included.
• If you attach a battery while the power is off, the power switch LED on the front panel will
blink.
• While the battery is in use, the amount of remaining battery power is indicated in the upper
right of the display. To correctly display the amount of remaining battery power, select the
battery type in the system settings.
[Reference] Section
5.9, Remaining Battery Power Display (Option)
• The DC power supply has precedence when it is used at the same time as the battery.
When you switch between the power supplies (battery to DC power supply or DC power
supply to battery), the LV 5380 may restart.

Applying SDI Input Signals
Apply an SDI signal to the SDI input connectors (INPUT SDI A and INPUT SDI B).
Figure4-6 SDI input connectors
• The SDI input connectors (INPUT SDI A and INPUT SDI B) are for component SDI (serial
digital interface) signals only. Do not apply analog video signals, composite SDI signals, or
any other kind of signal other than component SDI.
• The SDI input connectors (INPUT SDI A and INPUT SDI B) are terminated internally at 75
Ω
.
You do not need to attach a terminator. Connect each of the external reference input
connectors to a cable with a characteristic impedance of 75
Ω
.
• Keep the SDI input signal strength at 800 mVp-p ± 10 % at the input signal source BNC
output connector. An SDI signal that is outside of this range may not be received properly.
• When viewing a single link signal in the 1-channel display, you can press the INPUT key on
the front panel to select which connector's signal you want to measure.
• The LV 5380 supports the formats listed in
Table 2-1
. In the default settings, the link format is
single, and the input format is detected automatically. To set the input format manually or
switch between the single and dual link formats, see section 5.1, “Setting the Input Format.”
