1. Install jumper between INIT and GND terminals of the RS-485 port.
2. Apply power to Smartmod unit.
3. Read parameter words to see current parameters.
4. Write changes if necessary.

SmartMod Analog I/O utilizes both Modbus Registers (40001-40030) and Coils (1-11). It is possible
to access all data using Registers only, because the Coils can be accessed through Register 40010.
The following tables lists all Modbus I/O data available.

The INIT Default RS485 Settings Are:
Modbus ID = 1
Baud rate = 9600
Parity = None
Stop Bits = 1
Data Bits = 8
No handshake
Note: There are 2 types of default settings possible:
1. Factory default as described in section 1 (Specifications)
2. Default after INIT as described in section 3 (INIT Default Setup)
4 Configuration DATA
SmartMod Configuration settings are mapped into Modbus Register space.
This configuration data may be modified with any Modbus/RTU Master device.
For convenience, Horner APG has developed a variety of Cscape application
files which allow an OCS (Xle, NX, LX, QX) to act as a SmartMod configurator.
Initial configuration of SmartMod module should be done on an individual
basis, since all modules come from the factory with a default Modbus ID of 1.
Once each module on the network has its own unique Modbus ID, further
configuration adjustments can be made with the entire network powered.
All configuration parameters listed below (except 40012 Channel Enable) are
stored in EPROM. That means they should not be constantly rewritten.

If Coil 9 (Watchdog Enabled) is set,
Coil 10 (Watchdog Event) will set if
the Watchdog Timeout value is
exceeded. The Watchdog Timeout
value is set in Register 40009.
When set, Coil 10 can be reset by
the controller when normal
communications resumes.
The Power-up Event (Coil 11) is set
every time the power is applied. It
can be cleared by the controller if
desired.
6 Installation / safety
Warning: Remove power from the OCS controller, CAN port, and any peripheral equipment
connected to this local system before adding or replacing this or any module.
a. All applicable codes and standards should be followed in the installation of this product.
b. Shielded, twisted-pair wiring should be used for best performance.
c. Shields may be terminated at the module terminal strip.
d. In severe applications, shields should be tied directly to the ground block within the panel.
e. Use the following wire type or equivalent: Belden 8441.
For detailed installation and a
handy checklist that covers panel box layout requirements and
minimum clearances, refer to the hardware manual of the controller you are using.
When found on the product, the following symbols specify:
