Operation Tankvision Gauge Link

The modbus address is always the same as the level address stored in holding registers 0000
– 0031.
So for example the gauge address to read level for the 1st gauge is address 01 in holding
register 0000.
The gauge address to read temperature elements for the 3rd gauge is address 16 in holding
register 202.
ALLDEVICES(return)
This command basically does the same command as above, but all 32 registers for each block
are displayed.
This command is useful in troubleshooting, to check if there are no random registers
containing values.
BLANKXX(return)
Where XX represents a row of gauge parameters between 0 and 32.
XX must be entered as a 2 digit number. E.g. 3 must be entered as 03.
This command blanks all the parameters for a gauge and defaults all the parameters back to
255. This parameter is used if you require to remove a gauge from the system. All gauges
above this gauge will be automatically shuffled down and fill the space which was originally
blanked.
