| |
2.1 | 8 | Adapter includes a switch to connect a 120 Ohm terminal resistor to RS-485 lines. |
| |
1.1 | 9 | |
| |
2.1 | 10 | Device is compatible with the following operating systems: Windows 98, Windows ME, Windows 2000, Windows XP, Windows Vista, Windows 7, Windows 8/8.1, Windows 10, Mac OS 8/9, Mac OS X, Linux 2.4 and above. |

4.1 | 12 | The BMS USB-RS485 interface adapter performs the following functions: |
| |
1.1 | 13 | |
| 14 | * conversion of USB interface signals to a two-wire trunk RS-485 interface signals with galvanic isolation (Vrms = 1000V); | ||
| 15 | * power supply and information exchange with BMS Logic devices using the ElectricDeviceMonitor software. | ||
