IpCAS ipEther232 - ipNTP Technical Details

8.5 Technical details for ipNTP
Great emphasis was placed on compatability during device design. Nevertheless
there are some minor restrictions.
• The DCF77-Reception has a accuracy of ± 8 msec.
• The GPS-Reception has a accuracy of ± 1 msec.
• Free running quality: ± 10 ppm at a static temperature of +10°C to
+ 50°C.
• The emergency clock has an accuracy of 50ppm by a temperature
(+10°C to +50°C).
