This unit offers status reporting via a HTTP\nweb interface - screenshots taken from the testing of the\nactual item for sale below. A decent outdoor GPS antenna\nwith a gain of 26dB or more will be required for the unit to\nreceive time correctly - I usually have matching types\nlisted separately; feel free to ask for a recommendation if\nnecessary. Almost any professional grade 5V outdoor antenna\nshould work well. The antenna needs to be sited outdoors\nwith a full view of the sky. A very basic test antenna is\nincluded to allow you to check out the unit upon receipt.\nYou may need to move the unit outdoors (on a long extension\nlead perhaps) so that the test antenna can obtain a full\nview of the sky. Operation in the shadow of a building or\nthrough a window is unlikely to be successful. \u003c\/em\u003e\u003cem\u003eThe\ndefault log-on credentials will allow you to configure the\ndevice (root, endrun_1) via the web interface.
