Useful Tips & Basestation Programs for FR24-box Feeders & How To Configure Pt.2
Initially through an email, support will give you a link to this page. Write that IP number down for reference.
DEVICE INFO:
MAC ADDRESS: bc:6a:29:85:ab:48 Fingerprint of the FR24 receiver
S/W VERSION: FR24-3.8,101,66
F/W VERSION: 21
ROOT DEVICE: /dev/mmcblk0p2
UPTIME: 1 days 23:23:37 Time since the power was cycled or rebooted.
GPS INFO:
POSITION: 9.xxxx,123.xxxx 85.0m [AMSL] Altitude of GPS sensor above mean sea level
TEMPERATURE: 49.37'C Temperature of a component inside the FR24 receiver
See excerpts from the link below in this post on the effect of lengthening the GPS cable. Splicing a length of copper sheath coax has basically no effect on FR24s use of timing. The GPS sensor could be mounted at the tip of your mast with your antenna and provide a true altitude of your antenna rather than just the distance vertically limited by cable length.
STORAGE:
ROOT PARTITION USAGE: 103M/622M (18%)
USER PARTITION USAGE: 3.6M/2.3G (1%)
STATUS:
RECEIVER SOFTWARE: ON [stop, display log]
RAW FEED [30334]: UP, NUM CONNECTED: 0 Raw Feed port of the Beast receiver,in digital format used by Radar View and other basestation programs. State is UP or Down. NUM CONNECTED is the number of basestation programs using this port
BS FEED [30003]: UP, NUM CONNECTED: 0 Port Only used by FR24 feed and prohibited to be used to feed another service per your hosting agreement. State is UP or Down
If either FEED is down contact support@fr24.com with a screenshot. Only one problem per email.
NETWORK CONFIG:
IP: 192.168.254.134 NETMASK: 192.168.254.255 The Network Config settings are set by clicking on the Network Configuration Link below on that page. These are used whenever the receiver is restarted either by power interruption or accessing the web page by URL. You can change the IP to suit your configuration. If you are connecting the ethernet directly to the modem and are accessing the page for the first time, the default network settings will work ok with little modification. Just check them.
GW: 192.168.254.254
DNS1: 192.168.254.254
DNS2: 8.8.8.8
DNS3: 8.8.4.4
Please note these settings are the result of using a wireless networked pc for the receiver to connect to the internet. If you connect direct to the modem, the DNS settings 8.8.8.8 or 8.8.4.4, which are Google DNS, would be your settings for DNS1 and or DNS2.

Cable Delay
"GPS position as well as precise UTC time is determined at the point the GPS signals are received at the antenna. Since the antenna is
typically attached to the GPS timing receiver via a cable, signal propagation delays through the cable cause the time calculated by the
receiver to be slightly behind UTC. In GPS clocks with nanosecond and microsecond accuracies this is a critical factor. In products
such as network time servers cable delay is not important because time transfer over IP networks degrades the time to the millisecond level.
Cable delay is a function of the cable type. RG-59 cable for example typically delays the signal 1.24 ns/ft. For 50 feet of cable (15 m)
the delay would be 62 nanoseconds. Cable delay is removed by advancing the antenna signal inside the GPS receiver. In this example,
advancing the signal +62 nanoseconds removes all cable latency. Solutions such as the GPS Down/up converter also introduce
signal latency but this latency can also be removed by adjusting the signal. All precision GPS timing receivers with nanosecond or
microsecond timing accuracy have the ability to compensate for cable delay."
