4 Sync. Out

(TTL level @ high impedance,
0 to 2 Volt @ 50 Ohms )
To operate SyncIn correctly, a SyncIn driver circuit has to be used.
Minimum Sink Current (TTL Low Level) of the SyncIn Driver has to be
5mA. At 5mA Sink Current the input level at the SyncIn camera input
drops below 0,8Volts.
Source Current (TTL High Level).of the SyncIn Driver is neglible (0mA)
Easiest driver circuit is a Transistor working in open collector
configuration.
SyncIn input voltage limit ranges from – 5 Volts to + 30 Volts. Voltages
applied beyond these limits may damage the SyncIn Input.
SyncOut has a built in 50 Ohm driver.
At 50 Ohm termination, the driver voltage is in between 0 (low level) to
~2 Volts (high level). At high impedance termination, the driver voltage
is in between 0 (low level) to ~4 Volts (high level).
SyncOut voltage limit ranges from 0 Volt to + 5 Volts. Voltages applied
beyond these limits may damage the SyncOut Output.
The Auxiliary connector may also be used to update the firmware of the
camera. Please use the USB2 programming adapter cable.
