Timing Settings
There are four kinds of timing mode. They are GPS timing, LTC timing, NTP timing and
Local timing (Ethernet connection to web browser computer).
Only one timing mode can take effect at a time. See the details of each mode below:
GPS timing
means that the analog clock and digital timer are controlled by a GPS timer
via the RS232 interface. To achieve this function, baud rate and parity should be set.
Check the box “GPS,” the GPS timing function is enabled, otherwise, not.
LTC timing
means timing is based on LTC code via XLR interface. LTC in both SMPTE
and EBU code are supported according to IEC standard. Pin 1 is GND, and pin 2 & 3
receive LTC data (see the picture below). Check the box “LTC,” the LTC timing function
is enabled, otherwise, not.
