Factory Initial Values
The features of the interface module are initialized at the factory with a set of initial values.
(See Table 2 Initial Input Values for the complete list of factory initial values.) For reference purposes,
the Modbus slave address is preset to hex 0x01, the baud rate is 9600, Parity type is None, and
the Stop Bits is "1".

Calibration
The interface module is shipped from the factory as fully calibrated devices. Throughout the
lifetime of the module there may be need to verify or adjust the calibration of the device. The
following verification and adjustment process should only be completed using NIST traceable
calibration equipment. Perform the calibration steps in the order listed.
Required Equipment
• Computer running the utility software or another Modbus Master program.
• A NIST traceable DC Voltage Standard with ±10Vdc range.
Setup Steps
1. Allow unit to warm up for 15 minutes.
2. Short all the +Input pins together using short jumper wires.
3. Short all the -Input pins together using short jumper wires.
4. Connect the +Input wires to the Positive terminal on the DC voltage calibrator.
5. Connect the -Input wires to the Negative terminal on the DC voltage calibrator.
6. Install the utility software or another Modbus Master Program to communicate with, and
calibrate with the module via serial port or a TCP/IP connection.
