3. Application Note

3.1 INIT* pin Operation

Each I-7000 module has a build-in EEPROM to store con-

figuration information such as address, type, baudrate and other

information. Sometimes, user may forget the configuration of the

module. Therefore, the I-7000 have a special mode named “INIT

mode”, to help user to resolve the problem. The “INIT mode” is

setting as Address=00, baudrate=9600bps, no checksum

To enable INIT mode, please follow these steps:

Step1. Power off the module

Step2. Connect the INIT* pin with the GND pin.

Step3. Power on

Step4. Send command $002(cr) in 9600bps to read the configura-

tion stored in the module’s EEPROM.

Refer to “7000 Bus Converter User ManualSec.5.1 and

Getting Start” for more information.

3.2 Module Status

PowerOn Reset or Module Watchdog Reset will let all

output goto PowerOn Value. And the module may accept the host’s

command to change the output value.

Host Watchdog Timeout will let all digital output goto

Safe Value.The host watchdog timeout flag is set, and the output

command will be ignored. The module’s LED will go to flash and

user must reset the Module Status via command to restore normal

operation.
