Product information

Latching USB Cable Applied
Latching USB Cable applied to BASSO-1010UC has a latches on the USB connectors which provides accidental detachment. It is compatible with the existing USB 2.0 connectors.
Auto TogglingBASSO-1010UC has a built-in hardware feature that performs automatic toggling to prevent device from sending data at the same time causing a crash. This function prevents the RS-422 from forming a multi-drop network or crashing between output signals on the RS-485 network. As this function is provided by hardware side, setting interface mode with a switch enables auto toggling for each interface.
Slew-Rate Limit ControlThe BASSO-1010UC has a slew rate limiting function that inhibits electromagnetic emissions when communicating in RS-422/RS-485 interface. When this function is activated, the maximum communication speed is limited to 250Kbps. However, this function prevents malfunctioning of equipment in electromagnetic-sensitive environments such as hospitals and laboratories.
