displays are connected together. A unit can be set to one address within the range 0 through 9, and A through F. The
address range is 000 to FFF in ASCII HEX notation for a total of 4096 possible addresses.
Example corresponding commands are "A000 through "AFFF. The address range is 000 to FFF in ASCII HEX
notation. See the programming manual for more details on using this address command.
