RS 232/SDI-12 SELECTION
The SDI-12 protocol has very strict timing requirements. The operator may use the SDI-12 to
RS232 adaptor cable and then communicate to the SDI-12 port using the RS232 from a PC.
The "RS232" option must be selected via LCD screens. In this mode all of the timing/break
requirements of the SDI-12 are removed. Commands may be typed from a terminal program
such as "Hyperterm".
Note you must select 1200 baud, 7 bits, even parity and no handshaking.
If communications is via an SDI-12 device, you
MUST
select the SDI-12 option via the LCD
screen.
