K-114 BT - 1

+ KELLER Interface converter K-114 BT communication bluetooth / USB - RS485 The K-114 BT interface converter is used with KELLER products and enables communication between a device and computer via a Bluetooth interface. Description The K-114 BT converter converts serial signals from an RS485 interface into either Bluetooth or USB format. It can be supplied with power and charged autonomously, via the integrated battery or via a USB interface. In this way, the K-114 BT also supplies power to the connected end consumers. Bias or termination resistors may be activated in order to improve communication via the RS485. An echo function is also available. Multimeter/measuring analog signals The K-114 BT converter measures the power consumption of the connected devices and an discretionary voltage signal. These signals can be evaluated and displayed using the supplied software. If only one external device is connected, a functional check can be performed on it or the analog pressure signal can be displayed. The K-114 BT interface converter enables: ✓ Communication Bluetooth - RS485 / USB - RS485 (half-duplex) ✓ Power supply to connected devices (15 VDC) ✓ Measurement of applied signal voltage (0...12 VDC) ✓ Measurement of the power consumption of connected devices (0.150 mA) ✓ Optical status and configuration display (LED) ✓ Galvanic isolation between computer and converter (only when using Bluetooth) ✓ Selective activation of echo, bias resistors, or a termination resistor ✓ Software and drivers included in scope of delivery ✓ Charging of the battery via the USB interface Technical specifications Battery Run time Charging time Bluetooth Power supply to end consumers Voltage input Resolution of voltage input Current measurement Resolution of current measurement Interface / plug type RS485 configuration parameters RS485 interface parameters RS485 transmission rate RS485 bus devices RS485 cable length Storage/operating temperature H x W x D Weight Protection Lithium-Polymer 3,7 V / > 2,3 Ah approx. 18 h @ 20 mA consumers approx. 2.5 h @ 1 A 3.0 Classic (class 2) up to range of 10 m 15 VDC ± 5% / > 100 mA ( 1,5 W) 0.12 VDC / Accuracy 0,3 %FS (RI > 100 kQ) < 0,004 V 0.150 mA / Accuracy 0,3 %FS < 0,04 mA USB 2.0 / Mini USB-B ECHO / BIAS (2 x 560 Q) / Termination (120 Q) 8 Data bits, 1 start bit, 1 stop bit, no parity, half-duplex 9600 baud (default) / 115200 baud up to 128 bus devices (1/4 unit load) 0,75 m -10.50 °C 95 x 28 x 65 mm approx. 150 g IP 40 KELLER Ges. fur Druckmesstechnik DE-79798 Jestetten +49 7745 9214 0 H eurocenter@keller-druck.com Edition 07/2018 Subject to alterations Companies approved to ISO 9001 www.keller-druck.com

K-114 BT - 2

Bias resistor Supply to end devices (+VCC) Termination resistor Bias resistor The K-114 BT converter is activated via the ON/OFF button. The connection status and the selected configuration parameters are displayed via status LEDs. Communication can be established with the connected devices via an RS485 (half-duplex mode) bus at 9600 baud (default) or 115200 baud, 8 data bits, 1 stop bit and no parity. The K-114 BT interface converter has a Bluetooth Classic 3.0 inter­ face and a range of up to 10 m. The RS485 interface can be accessed via Bluetooth (or USB) through a virtual COM port. The...
