[Current Store(ja)] [Selection Guide][System Diagram][Catalog]

LTC from serial time data
Automatic Free running mode
SEIKO TMC100-J compatible
It works as slave clock
Time signal pulse
GPI port
19 inches 1U size

SL910 is interface to output LTC from the serial time data which SEIKO TMC100-J of the primary clock for broadcasting stations outputs.
When serial data break off more than 1 second because it has a Free running mode and are not input, it switches automatically.

“Input data”
It inputs the serial time data which is compatible with SEIKO TMC100-J.
The communication protocol is 2400bps, N81, and the electrical format supports in RS422/485 or RS232.
With the Free running mode, the data do not output it on the date and day of week.
When it switches from a sync mode to a Free running mode, it holds date data just before that, but is not updated even if it is past 24:00.

“LTC output ”
It is XLR balanced output.
When you connect unbalance, please connect only hot and GND.
It can change the reference output level by 3dB step to -30 to +7dBu in +4dBu.
The frame mode in the Free running is Drop or non-Drop, and the frame rate can set 29.97, 30.

“GPI port”
It outputs a pulse every day at (0:00) with per second, per minute, every hour.

“External synchronization”
When external synchronization signal of BB or LTC is input, it synchronizes the timing and outputs LTC.

“Display”
It indicates the time of TCG, TCR and the serial clock to front panel.
In addition, the decimal point of 1H, 1M and 1S indicates Drop frame, BB sync and serial clock sync.
In addition, depending on signal quality, TCR is readable in 1/30 to 20 times speed.

“Adjustment”
It does the mode set with a rotary encoder of the front panel right.
In addition, it can set any time in the Free running mode.

“Others”
In addition, please refer about a different shape, the display type.
