1.9. Connection of the RS485 to the SM-USB Module from IMKO

The SM-USB provides the ability to connect a SONO probe either to the standard RS485 interface or optionally to the IMP-Bus from IMKO, which enables the download of a new firmware to the SONO probe. 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 USB-Module SM-USB 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.

 Connection of the SONO probe to the EX9531 via RS485A, RS485B and 0V.

 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).

 The SONO probe logs in the window „Probe List“ after max. 30 seconds with its serial number.

Note 1:

In the Device-Manager passes it as follows:

Control Panel

 System  Hardware  Device-Manager

Under the entry “Ports (COM & LPT) now the item “USB Serial Port (COMx)” is found.

COMx set must be between COM1….COM9 and it should be ensured that there is no double occupancy of the interfaces.

If it comes to conflicts among the serial port or the USB-SM has been found in a higher COM-port, the

COM port number can be adjusted manually:

By double clicking on "USB Serial Port" you can go into the properties menu, where you see

"connection settings" – with "Advanced" button, the COM port number can be switched to a free number.

After changing the COMx port settings, SONO-CONFIG must be restarted.
