3. Application Notes

3.1 INIT* Pin Operation

Each CB-7000 module has a build-in EEPROM to store

configuration information such as address, type, baud rate and other

information. Sometimes, the user may forget the configuration of

the module. Therefore, the CB-7000 has 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:

Step 1. Power-off the module.

Step 2. Connect the INIT* pin with the GND pin.

Step 3. Power-on the module.

Step 4. Send command $002(cr) in 9600bps to read the

configuration stored in the module’s EEPROM.

Refer to “7000 Bus Converter User Manual” Sec. 5.1

and “Getting Started” for more information.

3.2 Module Status

PowerOn Reset or Module Watchdog Reset will set all

outputs to the PowerOn Value. The module can accept the host’s

command to change the output value.

Host Watchdog Timeout sets all digital outputs to the Safe

Value.The module’s status (read by command ~AA0) will be 04,

and an output command will be ignored.
