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, Baudrate=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.
2. $AAPN, See Section 2.18 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.
1.6
Dual Watchdog Operation for DIO, AIO
Dual Watchdog=Module Watchdog + Host Watchdog
The Module Watchdog is a hardware reset circuit to monitor
the module's operating status. While working in harsh or noisy
environment, the module may be down by the external signal. The
circuit may let the module to work continues and never halt.
The Host Watchdog is a software function to monitor the
host's operating status. Its purpose is to prevent the network from
communication problem or host halt. When the timeout interval
expired, the module will turn all outputs to predefined Safe Value.
This can prevent the controlled target from unexpected situation.
The EX9000 module with Dual Watchdog may let the
control system more reliable and stable.
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 resetted and the
output is not changed.
8
1.8 Digital O/P
The module's output have 3 different situation :
<1>Safe Value. If the host watchdog timeout status is set,
the output is set to Safe Value. While the module receive the output
command like @AA(Date) or #AABBDD, the module will ignore
the command and return "!". And will not change the output to the
output command value. The host watchdog timeout status is set
and store into EEPROM while the host watchdog timeout
interval expired and only can be cleared by command ~AA1. If
user want to change the output it need to clear the host watchdog
timeout status firstly and send output command to change the output
into desired value.
<2>PowerOn Value. Only the module reset and the host
watchdog timeout status is clear, the module's output is set to
predefined Power On Value.
<3> Output Command Value. If the host watchdog timeout
status is clear and user issue a digital output command like @AA
(Data) or #AABBDD to module for changing the output value. The
module will response success (receive>).
1.9 Latch Digital I/P
For example, use connect the key switch to Digital input channel of
a digital input/output module and want to read the key stoke. The
Key input is a pulse digital input and user will lost the strike. While
reading by command $AA6 in A and B position, the response is that
no key stroke and it will lose the key stroke information. Respectely,
the read latch low digital input command $AAL0 will solve this
problem. When issue $AAL0 command in A and B position, the
response denote that there is a low pulse between A and B position
forakeystroke.

2.0 Command Sets
2.1 %AANNTTCCFF
Description:Set Module Configuration.
Syntax:%AANNTTCCFF[CHK](cr)
% a delimiter character
AA address of setting/response module(00 to FF)
NN new address for setting/response module(00 to FF)
TT type 40 for DIO module
CC new baudrate for setting module.
FF new data format for setting module.
If the configuration with new baudrate or new checksum
setting, before using this command, it is needed to short the
INIT* to ground (or sliding the INIT* switch to the Init ON
position of rear side). The new setting is saved in the
EEPROM and will be effective after the next power-on reset.
Response: Valid Command: !AA
Invalid Command: ?AA
Example:
Command: %0102240600 Receive: !02
Set module address 01 to 02, return Success.
