Description
The K-114 BT cable converter is used with KELLER devices and provides communication between the device and a computer via a Bluetooth interface.
The K-114 BT converter converts RS485 serial interface signals into Bluetooth or USB format. It can be powered and charged for autonomous operation via a built-in battery or USB interface. Thus, the K-114 BT also supplies power to connected devices.
To improve communication via RS485, bias resistors or terminating resistors can be activated. An echo signal function is also available.
The K-114 BT converter measures the power consumption of connected devices and the voltage signal. These signals can be recalculated and displayed using the software included. If only one external device is connected, functionality testing or analog pressure signal display can be performed on it.
