1.4 INIT* Mode
Operation
Each EX9000 module has a build-in EEPROM to store configuration
information such as address, type, baudrate and other information.
Sometimes, user may forget the configuration of the module. Therefore,
the EX9000 have a special mode named "INIT* mode" to help user to
resolve the problem. The "INIT* mode" is setting as Address=00,
Budrate=9600bps, no Checksum .
Originally, the INIT* mode is accessed by connecting the INIT*
terminal to the GND terminal. New EX9000 modules have the INIT*
switch located on the rear side of the module to allow easier access to
the INIT* mode. For these modules, INIT* mode is accessed by sliding
the INIT* switch to the Init position as shown below.
To enable INIT* mode, please following these steps:
Step1. Power off the module
Step2. Connect the INIT* pin with the GND pin.
(or sliding the INIT* switch to the Init* ON position)
Step3. Power on
Step4. Send command $002 (cr) in 9600bps to read the
Configuration stored in the module's EEPROM.
There are commands that require the module to be in INIT* mode.
They are:
1. %AANNTTCCFF when changing the Baud Rate and checksum
settings. See Section 2.1 for details.
