Set Digital Output Command
The Set Digital Output command is used to set the states of the
3 digital output lines. This command requires a data byte. The data
byte is used to specify the output states. Bits 0-2 correspond to the
states of digital outputs 0-2. If a bit is a 0 then the output will be set
LOW. If a bit is a 1 then the output will be set HIGH. Refer to Table
3.6. NOTE: This command ignores Bits 3-7 of the data byte.

Set Module Address Command
The Set Module Address command is used to change the
address of a 485SDA10. This command requires a data byte. The
data byte is used to specify the new address of the unit. The
address of a module is stored in non-volatile memory.
