CONFIGURATION
The DigiGate device is configurable through the DigiConfig via Modbus interface. For this purpose, the device must be
set into the “Configuration mode“. In this mode, the device does not work as a master in the Modbus network, but starts
operating as a slave, receiving commands from the configuration software, which will assume the master function during
the configuration procedure. For entering the “Configuration mode“, press the CFG key, make sure that the status LED
starts flashing slowly (once per second, approximately).
For leaving the “Configuration mode“, press the CFG key again. At this moment, the device will be reset and will then
start operating with the new configuration applied.
Configuration software
The DigiConfig application is a program for Windows® used for configuration of all operation parameters of the
DigiGate. For installing the application, run the DigiConfigSetup.exe file from the product CD and follow the given
instructions.
DigiConfig contains a complete help file, providing all the information necessary for its full use. For consulting the help
file, start the application and select the “Help” menu or press the F1 key.
If you do not have the CD which comes with the product, consult the manufacturer’s homepage in order to obtain the
DigiConfig installer as well as the additional manuals of the product.
