1. LOCAL CLOCK SERIVCE:
MTS200 works on internal clock during Unlock conditions or when internal ntp driver is not synchronized
with GPS receiver. User, cannot restart the NTP service during unlock conditions if this parameter is
disabled. It is recommended to keep local service enabled. Local clock stratum in unlock conditions will
come in effect only when local clock is enabled.
2. LOCAL CLOCK STRATUM:
Local clock stratum can be configured from 0 to 15. This can act as a alert to ntp clients whenever
MTS200 is in unlock conditions. As internal ntp driver always provides s1 value in ntp response
to ntp clients, it is necessary to configure the stratum value -1 to whatever stratum is required at ntp client
end.
3. NTP SERVICE:
NTP Service can be restarted using this option. It is necessary to restart NTP service whenever this
change in any parameter related to NTP settings such as local cloak enable/disable. Stratum,
authentication keys, broadcast etc.
To change configuration of above parameters, follow below steps :
1. Go to specific parameter which want to be modified.
2. Press OK key.
3. Modify the parameter value.
4. Again press OK key.
GPS RECEIVER PARAMETERS:
1. SPD: (Antenna Cable Propagation delay compensation).
The internal GPS receiver outputs a 1PPS signal, the rising edge of which is placed at the top of the GPS
or UTC one second time mark epoch as specified by the Time Mode command. The 1PPS Cable Delay
Correction command allows the user to offset the 1PPS time mark in one nanosecond increments relative
to the measurement epoch.
