If a write block with all zeroes is written to the module, the default
selections will be:
1 to 5V dc or 4 to 20mA (depends on voltage/current selection jumper)
BCD data format
no real time sampling (RTS)
no digital filter
no
scaling
no
alarms
Note: Input data is set to 0 until an initial block transfer write is received
by the module.
