-===== Multiple GX Devices for increasing number of tank inputs =====+===== A) For in chapter 1.4 - Multiple GX Devices for increasing number of tank inputs =====

 ==== Introduction ==== ==== Introduction ====
  
 The number of tank inputs of a GX Device, such as the Cerbo GX and the Venus GX can be expanded by connecting multiple GX devices together in a VE.Can network. The number of tank inputs of a GX Device, such as the Cerbo GX and the Venus GX can be expanded by connecting multiple GX devices together in a VE.Can network.
  
-Make sure to designate one GX device to be the "main" one; and the others the secondary one. There is no practical limit on how many can be used - most likely the number of source addresses on a VE.Can network is the limit, which is 252 addresses. A Cerbo GX, with 4 tank inputs, will use up 5 addresses: one for itself, and one for each tank input.+Make sure to designate one GX device to be the "main" one; and the other(s) to be the "secondaryone(s).

   - Only connect the main GX device to the Ethernet network - do not connect the others. For example the MFD App on Marine MFDs is not designed to work with multiple GX devices on one Ethernet network.   - Only connect the main GX device to the Ethernet network - do not connect the others.

   - (optional - only when using ModbusTCP protocol): only enable ModbusTCP on one of the GX Devices   - (optional - only when using ModbusTCP protocol): only enable ModbusTCP on one of the GX Devices

   - Assign each GX Device its own unique number. Use the test feature when to make sure all went well   - Assign each GX Device its own unique number. Use the test feature when to make sure all went well
  
 +Lastly, on the main GX Device, check if all sensors show up in the Device list and work well.

 +===== B) Changes to the NMEA2000-out chapter ====
 +
 +Many wording changes: "Send data to VE.Can" was reworded to "NMEA2000-out" and much more.
 +
 +Also there is now a menu to change the VE.Can/N2K Device Instances.
 +
 +Which means that this document needs amending as well: https://www.victronenergy.com/live/ve.can:changing_nmea2000_instances.
 +
 +===== C) Tank input configration ====
  
 +tbd. Include the new min /max, as well as ten point calibration and so forth. Include screenshots.
