3. Application Note
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 the user resolve the problem. The “INIT mode”
is setting as Address=00, baud rate = 9600 bps, 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. Set Power on.
Step 4. Send command $002(cr) in 9600 bps to read the configura-
tion stored in the module’s EEPROM.
Refer to “CB-7000 Bus Converter User Manual” Sec. 5.1
and “Getting Started” for more information.
3.2 Module Status
Power-On Reset or Module Watchdog Reset will put all
outputs to the Power-On Value. The module may accept the host’s
command to change the output value.
Host Watchdog Timeout will put all digital outputs to the
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.
