My PG/PC has only USB ports. How can I go online to my inverter using USS protocol?
If your PC/PG only has USB interfaces instead of the RS232 interface, you can use standard USB<->RS232 converters. Please make sure that you use up-to-date drivers from the respective manufacturers, particularly also for 64-Bit-Systems.
Note
If data transfer rate problems occur, then the min. baud rate should be set to 38400.
Settings
| Drive Monitor | Interface | COM1 - COM4 | A COM port number can be selected between 1-4 (dependent on the PC setting). |
|---|---|---|---|
| Baud rate | 9600 or higher | A higher baud rate might give the better access; e.g. 38400 Baud | |
| Bus operation RS485 | Automatic mode | Online operation is not possible without this setting | |
| STARTER | Access point | DEVICE(STARTER, SCOUT) --> PC COM-Port (USS) | |
| Interface Parameter Assignment Used | PC COM-Port (USS) | ||
| Interface | COM1 - COM7 | A COM port number can be selected between 1-7 (dependent on the PC setting). | |
| Baud rate | 9600 or higher | A higher baud rate might give the better access; e.g. 38400 Baud | |
| RS485 | Automatic mode | Online operation without this setting is not possible | |
| Device Manager | Ports (COM & LPT) | USB<->RS232-Adapter | E.g. ATEN USB to Serial Bridge (COM4) |
| Properties of the Port: | |||
| Bits per second | 9600 | Leave the presetting's | |
| Data bits | 8 | ||
| Parity | None | ||
| Stop bits | 1 | ||
| Flow control | None | ||
| COM Port Number | The COM port number can be modified between 1-7 when required | ||
