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, a user may forget the configuration of the
module. Therefore, the CB-7000 have a special mode named “INIT
mode”, to help user to resolve the problem. The “INIT mode” is
setting as Address=00, baud rate=9600bps, no checksum
To enable INIT mode, please follow these steps:
Step 1. Power-down the module.
Step 2. Connect the INIT* pin to the GND pin.
Step 3. Power-up the module.
Step 4. Send Command $002(cr) in 9600 bps 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 will set all output to the Safe
Value.The module’s status (read by Command ~AA0) will be 04,
and the output Command will be ignored.
