1.3 Default Settings

Default settings for the EX-9016 module are as follows:
. Module Address: 01

. Analog Input Type: Type 05, -2.5 to +2.5V
. Baud Rate: 9600 bps
. Checksum disabled
. Engineering unit format
. Filter set at 60Hz rejection

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.

1.5 Module Status for DIO, AIO

Power On Reset or Module Watchdog Reset will let all

output goto Power On Value. And the module may accept the host's
command to change the output value.

Host Watchdog Timeout will let all output goto Safe Value.

The module's status(read by command~AA0) will be 04, and the output
command will be ignored.

1.7 Reset Status

The Reset Status is set while the module power on or reset by module
watchdog and is cleared while the command read Reset Status ($AA5)
applied. This is useful for user to check the module's working status.
When the Reset Status is set means the module is reset and the output
may be changed to the PowerOn Value. When the Reset Status is clear
means the module is not rested and the output is not changed.
