Set analog output range.
Address: Analog output range is written to address: 30101Bh.
Default is "00h". (Analog output range: 10V - +10V)
This value need not be written when the default is used.
Address: Module is started by writing "01h" to address: 301010h.
When started, the analog output data becomes valid.
Address: By writing 2 bytes to address: 305000h, the module can output
data from CH0. In subsequent operations, the module can write
analog output data with 2 bytes at a time, up to CH3.
Address: Error status can be checked by reading address: 300011h.
