A.1 INIT Mode
Each I-7000 and M-7000 module has a built-in EEPROM to
store configuration information such as module address, type
code, Baud Rate, etc. Occasionally, the configuration of a
module may be forgotten and there are no visual indications
of the configuration of the module. It is difficult to
communicate with the module when the configuration of the
module is unknown. To help avoid this problem, the I-7000
and M-7000 series has a special mode called
“INIT mode”
.
When the module is powered on in
“INIT mode”
the
configuration of the module is reset as follows, allowing it to
be operated as normal.
1.
Address: 00
2. Baud Rate: 9600 bps
3. No checksum
4. Protocol: DCON
The configuration information stored in the EEPROM is not
changed and can be read by sending the $002(CR) command
at 9600bps.
There are commands that require the module to be in INIT
mode. They are:
1.
%AANNTTCCFF when changing the Baud Rate and
checksum settings. See Section 2.1 for details.
2. $AAPN, see Section 2.23 for details.
