3. Operation Principle
3.1 INIT* Pin
All I-7000 modules contain an EEPROM to store configuration
information. Therefore the user is difficult to find out the status of
the I-7000 modules. The user can connect the INIT*_pin to
GND_pin and power on the module. The I-7000 modules will
go to
the factory default setting without changing the EEPROM data.
The factory default setting is given as following:
address =
00
baud
rate
=
9600
checksum
=
DISABLE
data format
= 1 start + 8 data bits + 1 stop bit
If the user disconnect the INIT*_pin and GND_pin, the I_7000
module will be auto configured according to the EEPROM data. The
user is easy to find the EEPROM configuration data in the default
setting. The steps are shown as following:
Step 1: power off and connect INIT*_pin to GND_pin
Step 2: power on
Step 3: send command string
$002[0x0D]
to the module, the module
will return back the EEPROM data.
Step 4: record the EEPROM data of this I-7000 module
Step 5: power off and disconnect INIT*_pin and GND_pin
Step 6: power on
