WARNING
◇ Turn off the power (DC24V) when connecting the cable from the
terminal.
The CM-BASEα(A) transmits data via 4-20mA signals. The CM-BASEα(D) transmits data
to a computer via RS-232C.
(1) CM-BASEα(A)
The provided cable connects to the base of the CM-BASEα(A), and it provides power
(DC24V) to the instrument and transmits Brix data via DC 4-20mA. Brix values ranging
from -2.0 to 33.5% are communicated as DC ranging from 4 to 20mA respectively.

Transmit data
aa.a,bb.b
aa.a represents Brix value. The Brix display range is
"-2.0 to 33.5".
When Brix value is less than -2.1, LL.L will be
displayed.
When Brix value is more than 33.6, HH.H will be
displayed.
bb.b represents temperature.
