I-7088I-7088 User Manual, Rev: A1.0883. Operation Principles & ApplicationNotes3.1 INIT* _pin Operation PrinciplesAll I-7000 modules contain an EEPROM that can be used tostore configuration information. Consequently, it is difficult forthe user to determine the status of the I-7000 module. If theINIT*_pin is connected to the GND_pin while powering on themodule, the modules will enter the factory default settingswithout changing the EEPROM data. The factory default settingsare as follows:Address = 00Baud Rate = 9600Checksum = DisabledData Format = 1 Start + 8 Data + 1 stopIf the INIT*_pin is disconnected from the GND_pin, the I-7000 module will be automatically configured according to theEEPROM data. It is easy to determine the EEPROMconfiguration data in the default settings using the following steps:Step 1: power off of the module and connect the INIT*_pin to theGND_pinStep 2: power on the moduleStep 3: send the command string $002[0x0D] to the module. Themodule will respond with the EEPROM data.Step 4: record the EEPROM data for this I-7000 moduleStep 5: power off the module and disconnect the INIT*_pin andfrom GND_pinStep 6: power on the module
