inside could be damaged by electrostatic discharge on the open connector. Use the originally supplied
antenna only.
TC (5-pin LEMO)
The TC connector is a 5-pin LEMO socket. It accepts and distributes LTC (Longitudinal Timecode)
signals. It can be used to
jam-sync the camera timecode to a timecode generator or another camera
transmit the camera timecode to a timecode generator or another camera
SDI 1&2 (BNC)
Besides the viewfinder output, SDI 1&2 are the main monitoring outputs of the camera. The camera
menu offers various settings to configure the outputs such as surround view, status information or frame
lines. Both SDI BNC connectors output SDI signals in
1920 x 1080 (422 1.5G, 422 3G, 444 3G)
3840 x 2160 (422 6G)
according to SMPTE standards 292M, ST 424:2012 and ST 2081.

A BNC socket for reference signal input, the SYNC IN connector accepts analog Black Burst signals
and Tri-Level HD signals.
BAT (8-pin LEMO)
The BAT connector is the main power input of the ALEXA Mini LF and accepts an input voltage range
from 11.0 to 34.0 V DC. You can use power cables KC50-S (K2.75007.0) or KC50-SP-S (K2.0001275)
or one of the various on-board adapter plates for V-Mount and Gold Mount batteries to supply the
camera with power.
Connecting or disconnecting devices or cables while recording can disturb the image/audio signal
due to static electricity.
