A.1. INIT Mode
Each I-7000 and M-7000 module has a built-in EEPROM that can be
used to store configuration information, such as the module address,
Type Code, and 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 to the default settings
shown below, 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 other commands that require the module to be in INIT
mode. They are:
1. %AANNTTCCFF, which is used when changing the Baud Rate
and checksum settings. See Section 2.1 for details.
2. $AAPN, see Section 2.36 for details.
