1.3 Default Settings

Default settings for the EX-9017/17F/17R/17FR modules are as
follows:

. Module Address: 01
. Analog Input Type: type 05
. Baud Rate: 9600 bps
. Checksum disabled
. Engineering unit format

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.

1.6

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 rested and the output is not changed.

series need connect external shunt resistor, 125Ohms, 0.1%

Type code 08 09 0A 0B 0C 0D

Zero Input 0V 0V 0V 0mV 0mV 0mA

Span +10V +5V +1V +500mV +150mV +20mA

Calibration Sequence:

1. Connect calibration voltage/current to module's channel 0.

2. Warm-Up for 30 minutes

3. Set the input type of module which you wish to calibration.

4. Enable Calibration (P.24)

5. Apply Zero Calibration Voltage

6. Preform Zero Calibration Command (P.16)

7. Apply Span Calibration Voltage

8. Perform Span Calibration Command (P.15)

9. Repeat step4 to step 8 three times.

Warning: Please don't calibrate before you really understand.
