0003 to 00FA Hex (3 to 250 decimal)
The CompoWay/F command response code is
stored in hexadecimal code.
The data from just after the response code until
just before the ETX is converted from ASCII to
hexadecimal and stored in order from the right-
most word to the leftmost word.
Receive data words
5 6 7 8 Rightmost word
1 2 3 4 Leftmost word
Always 0005 hex (5 decimal)
00 to 99
Set the area type (2 digits) and the first read
address (6 digits). The leftmost 16 bits of the first
read word specify the address and the rightmost 8
bits specify the bit location. Set the rightmost 8 bits
to 00 when bit access is not required.
Set the number of elements to read.
