Setup serial output, Setup timecode out – Meinberg GEN170TGP User Manual

Page 13

SETUP SERIAL OUTPUT

This menu lets the user select the serial ports' mode of operation. COM0 transmits the

current date and time using Meinberg's standard string. This string can be sent
automatically once per second, once per minute or on request by ASCII '?' only.

SETUP TIMECODE OUT

This menu lets the user configure the card's IRIG/AFNOR time code output. The

CODE: parameter selects the desired code frame format (IRIG or AFNOR), and the
TIME: parameter determines whether the transmitted code should carry UTC, or local
time.

Since most time code formats do neither include the UTC offset of the transmitted

time, nor a flag which reports the current DST status, the recommended setting is UTC in
order to avoid unexpected time steps of the connected time code receivers.

The IEEE1344 signal frame also contains a Time Figure Of Merit (TFOM) flag which

reflects whether the time code generator is synchronized, or not. If the IEEE1344 code is
selected then an additional parameter is displayed in the lower right corner which
determines whether the TFOM flag reports the real current synchronization status
(EN_T), or whether it always reports the generator was synchronized (DI_T). The latter
setting can be useful in testing scenarios.
