The SM-USB provides the ability to connect a SONO probe either to the standard RS485 interface or to the IMP-
Bus from IMKO. In fact that the IMP-Bus is more robust and enables the download of a new firmware to the
SONO probe, the SONO probes are preset to the IMP-Bus. It is recommended to use the IMP-Bus for a serial
communication. Both connector ports are shown in the drawing below.
The SM-USB is signalling the status of power supply and the transmission signals with 4 LED´s. When using a
dual-USB connector on the PC, it is possible to use the power supply for the SONO probe directly from the USB
port of the PC without the use of the external AC adapter.
How to start with the SM-USB module from IMKO
•
Install USB-Driver from USB-Stick.
•
Connect the SM-USB to the USB-Port of the PC and the installation will be accomplished automatically.
•
Install Software SONOConfig-SetUp.msi from USB-Stick.
•
Connection of the SONO probe to the SM-USB, with 4 wires for power supply and serial interface.
•
Check the setting of the COM-Ports in the Device-Manager und setup the specific COM-Port with the
Baudrate of 9600 Baud in SONO-CONFIG with the button "Bus" and "Configuration" (COM1-COM15 is
possible).
•
Start “Scan probes” in SONO-CONFIG.
