-====== GX GSM ======
-DRAFT: function & product not released yet.
-===== 1. Introduction =====
-The GX GSM is an accessory for Venus-devices. It is a cellular modem; providing a mobile internet connection for the system.
-It requires a SIM card; and connects to the Venus-device with a (supplied) ??m USB cable.
-A small indoor GSM antenna is included. As an option we also sell an outdoor GSM antenna. (Add partnumber; and somewhere there must be a picture of it and specs, GX GSM datasheet!?)
-==== GPS ====
-Besides internet, the GX GSM also has a GPS receiver. To use that, buy the optional active GSM antenna. (Add part number)
-==== Compatibility ====
-  * Color Control GX
-  * Venus GX
-  * Octo GX
-The GX GSM requires Venus OS v2.20 or newer to be installed on the Venus-device.
-==== When to use a mobile router instead ====
-The GX GSM only provides an internet connection for the Venus-device: there is no option to share the internet to laptops, phones, or other devices.
-For installations where more devices need internet, such as a yacht or RV, consider installing a mobile router instead. More information here (link to proper chapter in Ccgx manual).
-===== 2. Installation =====
-Mount the device an connect the antenna. Consider using the outdoor antenna when installing the GX GSM in a closed metal enclosure.
-Insert the SIM card.
-Connect the GX GSM to the Venus device with the supplied USB cable. Use a USB hub in case all USB sockets are already in use.
-Connect DC power supply (8 to 70 VDC).
-===== 3. Configuration =====
-When using a SIM card with its  SIM-pin security disabled, the system will work without further configuration. Verify operation by .. ? (Check VRM Last log data?)
-Setting a SIM pin helps reducing the risk of the SIM card being stolen and used. Use a mobile phone to set the SIM pin, and there after configure it on the Venus device.
-Some mobile networks require manual configuration of an APN, user name and password. Contact your operator.
-===== 4. Trouble shooting =====
-^   ^ Step   ^  Details                                   ^
-| 1 | Power  | Check that the blue LED is either lit continuous or blinking  |
-| 2 | USB    | The modem must be connected to USB, and visible in the Settings -> GSM modem menu |
-| 3 | Simcard | (feature is still being added to the software) |
-| 4 | Signal strength | 15 or higher (and see below table)     |
-| 5 | Network | Check that a network name is visible. If it is not, contact your simcard provider and/or insert the simcard in a phone to double check its operation.
-=== Antenna reception interpretation ===
-Even when there is no simcard inserted, you can check signal strength.
-<code>
-= -113 dBm or less
-= -111 dBm
-= -109 .. -53 dBm
-= - 51dBm
-= not known or not detectable
--50 to -75 dBm: high signal
--76 to 90 dBm: medium signal
--91 to -100: low signal
--101 to -120 dBm poor signal
-</code>
-You also need to remember that an outdoor antenna typically increases received signal by 15 dB to 25 dB.  (verify)
-TODO: replace above by something meaning full, ie indicate the signal strenght to the user in such way that he doesn't need to memorize rssi or other tables.
