4. Operation Principles & Application Notes
4.1. INIT* pin Operation Principles
All I-7000 modules contain an EEPROM that can be used to store
configuration information. Consequently, it is difficult for the user to
determine the status of the I-7000 module. If the INIT* pin is
connected to the GND pin while powering on the module, the
modules will enter the factory default settings without changing the
EEPROM data. The factory default settings are as follows:
Address
=
00
Baud
Rate
=
9600
Checksum
=
Disabled
Data Format
= 1 Start + 8 Data + 1 stop
If the INIT* pin is disconnected from the GND pin, the I-7000 module
will be automatically configured according to the EEPROM data. It is
easy to determine the EEPROM configuration data in the default
settings using the following steps:
Step 1: Power off the module and connect the INIT* pin to the GND
pin
Step 2: Power on the module
Step 3: Send the command string $002[0x0D] to the module. The
module will respond with the EEPROM data.
Step 4: Record the EEPROM data for this I-7000 module
Step 5: Power off the module and disconnect the INIT*_pin from the
GND pin
Step 6: Power on the module
