Description
Product description
The K-114 BT interface converter is recommended to communicate with digital products from KELLER, such as pressure transmitters, manometers, or autonomous data loggers.
The interface converter supports two modes of operation:
– Communication via Bluetooth
– Communication via USB
The K-114 BT converter converts the serial signals of an RS485 interface into either Bluetooth or USB format. The converter can be supplied with power autonomously, via the integrated battery, or via a USB interface. In this way, the converter also supplies power to the connected devices. The battery can be charged via the USB interface. The converter measures available supply voltage and power consumption of connected devices. These signals can be evaluated and displayed using the supplied software. Bias or termination resistors may be activated if necessary in order to improve communication via the RS485. The device is configured using the „K114_Config“ software.
Bluetooth
General
The K-114 BT interface converter has a Bluetooth Classic 3.0 interface and a typical range of up to 10 m (device class 2). The partner device (master/PC) must support Bluetooth Classic 2.1 or higher.
Function
When the device is switched on, the Bluetooth module is activated automatically and the interface converter is visible to other Bluetooth devices. The K-114 BT must be paired with the receiving device before a connection can be established. Once a Bluetooth connection has been established, the interface converter can no longer be accessed by other Bluetooth devices. If you want to communicate via the USB interface of the converter, any existing Bluetooth connections must be terminated. If Bluetooth communication is established, any existing USB connection is interrupted.
