Meinberg TCR LANTIME - Manual (Page 30)

The submenu „IGNORE SYNC“ lets the user enable or disable the IRIG SYNC
simulation mode. If you want to use the IRIG-receiver without connecting an IRIG-
signal this mode will simulate a valid output for the NTP daemon. This is only for test
purposes. IGNORE SYNC should be disabled under normal operating conditions.
Press CLR/ACK to change the mode
SETUP: TCR PARAMETERS
IGNORE SYNC disabled
The submenu „DATE“ lets the user set the date of the IRIG-receiver. If no IEEE1344
extensions are present in the connected IRIG-signal, no date information is available
from it. The item „IEEE 1344“ must be set to ‘disable’ and the user must manually
enter the current date. Press CLR/ACK to edit and to confirm the date of the IRIG-
receiver. After setting the time manually the NTP daemon will be restarted
automatically.

The basic model of the TCR510 includes a voltage controlled temperature
compensated oscillator (VCTCXO). Its nominal frequency of 10 MHz is adjusted by
using two digital-to-analog converters (DACs). One of them is responsible for the
coarse tuning and the other one for the fine adjustment of the oscillator.
The value for the coarse-DAC is settable in the menu "OSCILL. AJUST" in the range
of -32768 to 32768. If the edited value exceeds the maximum value is stored. This
menu only lets the user modify the coarse-DAC (CAL). The fine-DAC (FINE) is
displayed but not to edit. It will be cleared automatically.
SETUP: TCR PARAMETERS
OSCILL. ADJUST: CAL:2341 FINE:3704
This value should only be changed by specialized personnel of company
Meinberg and not by the user!
The submenu „Reset IRIG parameters“ lets the user reset the IRIG-parameters to the
default values. The UTC parameters will be set to +00:00 and the system
configuration will be set to 0x00.
