### Q: How do I get the time-of-day (ToD) into the WRS Grandmaster?
|
|
|
|
|
|
|
|
A: The preferred way of synchronizing your WRS to an external reference
|
|
|
|
is to use 1-PPS & 10MHz from a GPSDO/Cesium/etc. and external NTP server
|
|
|
|
for time of day information. The [WRS User
|
|
|
|
Manual](https://www.ohwr.org/project/wr-switch-sw/wikis/current-release#documentation)
|
|
|
|
describes in section "3.4 Configuration Items that Apply at Run Time"
|
|
|
|
how you can set the IP address of the NTP
|
|
|
|
server.
|
|
|
|
|
|
### Q: We need to use 30m coaxial cable from the GPS to the WRS Grandmaster 10MHz/PPS signals and the cable will see strong temperature changes (15-35ºC).
