-= LIDAR B22 embedded HTTP Server
+= B22 Embedded HTTP Server
+
+This describes the LIDAR's web based interface running on its internal HTTP Server.
+
+== 1. Purpose
+Embedded HTTP server enables convenient configuration, control and monitoring of
+LIDAR hardware over network, regardless of computing platform used, utilizing
+standard web browser.
+
+== 2. Introduction to HTTP server provided web pages
+=== 2.1. Login Page
+To access embedded web, connect your computer to the same network as LIDAR.
+Open web browser of your choice and enter in the address field the IP address of
+corresponding LIDAR to which you have legitimate rights for operation.
+To have authorized access, a user name and password must be provided.
+Illustrative Figure 1 below shows login window. 
+
+==== Figure 1 #fig-1
+[[Image(01-lidar-http-login.png, nolink)]]
+
+=== 2.2. Opening Page
+Opening page looks similar to picture on Figure 2. Below we'll walk through
+System Menu.
+
+==== Figure 2 #fig-2
+[[Image(02-lidar-http-welcome.png, nolink)]]
+
+=== 2.3. Network Configuration
+You get the idea of what fields and network parameters can be altered on Figure 3.
+**You should manipulate these parameters only if you are confident what are you going to do!**
+You may loose connection to the device if wrong parameters are entered.
+
+==== Figure 3 #fig-3
+[[Image(03-lidar-http-network.png, nolink)]]
+
+=== 2.4. System Settings
+If System Settings menu is selected in System Menu, You'll see page like Figure 4.
+(Image of page continues on [#fig-5 figure 5].) This is very important place where most
+operational values can be altered and user intervention is regularly needed.
+
+==== Figure 4 #fig-4
+[[Image(04-lidar-http-system-settings.png, nolink)]]
+
+“Lidar Work mode” box serves for:
+  * Standby – all LIDAR systems may be ready, but no sampling is executed.
+    This mode is useful for temporary pausing sampling and laser radiation.
+  * Continuous – sampling rate is determined by specified measuring interval in milliseconds.
+  * Distance – sampling is performed in equal distances covered by vessel and calculated by position data from GPS.
+  * Mixed – logical OR function decides if measuring interval or covered distance triggers next sample.
+  * Gas refill modes – These are covered in special Gas Refill Manual and need extra caution! **BE CAREFUL!**
+
+“HLIF Lidar general settings” box combines several figures that present LIDAR
+optical characteristics. Thou, Accumulation count can be altered with little risk.
+Increasing it, in principle, improves  Signal to Noise (S/N) ratio. We recommend
+to leave it to 10 pulses per sample. Do not try to alter other figures in this box.
+
+==== Figure 5 #fig-5
+[[Image(05-lidar-http-system-settings.png, nolink)]]
+
+“Detector settings” box shows optimal gate delay, width and gain set for your
+installation. They depend on distance, distance variation and signal level respectively.
+**Handle with care!**
+
+“Laser Settings” box includes controls for powering on/off laser separately from
+other LIDAR unit electronics and enabling/disabling lasing.
+
+=== 2.5. Monitor & Control
+This page, as shown on Figure 6, combines all real time parameters you need to
+follow and take actions accordingly from time to time.
+
+“Controller” box shows controller GMT synchronized clock, that can be manually
+synced if there is need. Laser pulse and time counters since last gas refill
+must be checked regularly. Read [wiki:LidarGasRefill Gas Refill Manual] for that matter. 
+
+“GPS” box contents are self explanatory. 
+
+“Laser” box contents show:
+  * Temperature - Laser Temperature must be below 45(50), figure in brackets shows controller temperature.
+  * Pressure – in laser chamber must be 600-700 kPa
+  * Energy – pulse energy must not drop below 1500 micro Joule. Then gas refill is necessary.
+
+Other values make importance, if LIDAR malfunctions.
+
+“Gas Refill System” box displays statuses of several valves and includes some
+controls for manual intervention in gas refill procedures.
+
+**CAUTION! Do not attempt to gas refill or other gas manipulation prior to getting
+familiar with [wiki:LidarGasRefill Gas Refill Manual]. Severe damage may happen to
+LIDAR hardware.**
+
+“Internal storage” box includes hyperlinks to plain text log and ini files.
+
+==== Figure 6 #fig-6
+[[Image(06-lidar-http-system-monitor.png, nolink)]]
+
+=== 2.6. Data View
+Data view page enables to monitor last measured sample spectrum. It is good to
+have visual control over signal quality and features. See screenshot in Figure 7.
+Read [wiki:LidarGasRefill Gas Refill Manual] for that matter.
+
+==== Figure 7 #fig-7
+[[Image(07-lidar-http-online-data.png, nolink)]]
+
+=== 2.7. Log
+Log menu (Figure 8.) opens system log text file. It can be copied and sent over
+to support person, for troubleshooting in case problems arise.
