Dimensions 44 x 170 x 85 (H x W x D [mm] without plug)
optionally with mounting brackets:
19” rack, 1HU x 28DU = 44 x 483 x 85 (H x W x D [mm] without plug)
Weight approx. 1.35 kg
Ambient temperature -5 to 50ºC, 10-90% relative humidity, without condensation
Operation Web interface, telnet or SSH (via LAN)
In addition, operation is also possible with SNMP.
Accuracy GNSS (DCF input) to NTP server: typical < +/- 0.5 ms
DCF 77 radio receiver to NTP server: typical < +/- 5 ms 1)
NTP client to NTP server: typical < +/- 0.5 ms
GNSS (DCF input) or NTP client to clock lines typical < +/- 0.5 ms +
accuracy of the clock line
1) If necessary, the DCF source must be corrected with an offset
(see menu: local time source 3 DCF/GPS source correcture)
Time keeping (internal) After at least 24 hours of synchronization from the time source:
< +/- 0.1 sec. / day (< 1 ppm), measured during 24 h, at 20°C +/- 5°C.
In case of a loss of feed (based on internal RTC):
< 5 ppm, but with jitter of +/- 15 ms, measured over 24 h,
at 20°C +/- 5°C. (After 24 h, the deviation may increase further due to quartz aging)
The RTC time is available for at least 5 days after the loss of feed (RTC
supported by SuperCap).
Timeserver NTP V4 (fully V3 compatible), RFC 1305 (Port 123)
NTP authentication with MD5 key / autokey
SNTP (UDP), RFC 2030 (Port 123)
TIME (TCP/UDP), RFC 868 (Port 37)
DAYTIME (TCP/UDP), RFC 867 (Port 13)
Max. number of NTP and SNTP client requests: > 250 requests / sec.
(e.g. client requests every 60 seconds 15000 clients)
NTP Mode Server, Peer, Broadcast, Multicast
NTP slave clock lines: 1 line with up to 15 different time zone entries.
Communication through multicast:
