A. Appendix
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 Baud Rate and
checksum settings. See Section 2.1 for details.
2. $AAPN, see Section 2.31 for details.
