The K-114 converter and the connected transmitters are powered via the USB connection. An external power supply unit can also be connected to power multiple instruments. The K-114 converter is preferred for use with KELLER products. With the K-114 interface converter, you can... ...convert a USB signal to RS 485 (half-duplex) ...measure the applied signal voltage (0...12 VDC) e.g. the output signal voltage from a pressure transmitter ...measure the power consumption of connected end consumers in the 0...40mA range e.g. the power consumption of connected end consumers or the power output signal from a pressure transmitter The K-114 interface converter offers you... ...visual status and configuration displays (LED) ...electrical isolation between the computer and the converter ...diagnostic tools K-114 K-114-A K-114-B 17 Pin assignment for converter / connections K-114 plug-in screw terminal +Vcc RS GND RS 485-A 485-B K-114-A Fischer plug-in connector S 103 A054-130 2: +U-IN 1: GND 3: +Vcc 5: RS485-B 4: RS485-A K-114-B Binder female cable connector Serie 680 5-pole 2: +U-IN 3: +Vcc 4: RS485-A 1: GND 5: RS485-B Technical specifications Symbol Parameter Condition Min. typ.

The devices connected to the K-114 are supplied via the PC's USB output or via an external power supply unit (K-114 socket). KELLER products operate with fail-safe drivers that generate a logical «high» at the reception output in case of short-circuited, open or terminated inputs, in order to avoid invalid signal statuses. KELLER products also have a slew rate limitation which limits the edge steepness (i.e. slew rate) of the driver output. This prevents high-frequency emissions from devices and data lines. Up to a maximum of 128 transmitters can be connected to this RS485 master bus.

Functional overview for the K-114 U-USB USB Echo RS485 Bias Termination Bias High Speed Echo off Data sent from the PC (TX) aren't received by the PC. Bias network Prevents undefined bus levels when line drivers are in- active. Greater immunity to interference Termination Prevents reflections on the signal lines. High Speed Disables the RS485 driver's slew-rate limitation. This allows communication at higher transmission speeds (> 250 kbps). Unlike high speed mode, the standard mode (< 250 kbps) reduces reflections on the signal lines and provides better EMC behaviour. KELLER devices operate at transmission speeds < 250 kbps, so this function is not activated ex factory. 20 www.keller-druck.com LED display K-114 Power USB USB to RS485 Converter RX/TX RS485B GND RS485A +VCC RS485 External Supply 15 VDC GND Echo off Bias Termination High Speed on on on Power Ready to operate Flashing rapidly, error U-USB < 4,5 VDC Connect power supply unit Flashing slowly, error U-UOUT < 11,2 VDC Connect power supply unit Error RX/TX Shows the status of the transmission line (TX) and the reception line (RX).

RoHS This product is compliant with EC directive 2002/95/EC on the Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment (RoHS). Disposal This symbol on the product or the product documentation indicates that the product must not be disposed of as normal household waste at the end of its useful life. In order to prevent potential damage to the environment or to health as a result of uncontrolled waste disposal, this product must be separated from other waste and must be correctly recycled in order to ensure the sustainable use of the raw materials. 22 Help with fault analysis 23 Installing the K-114_Config software First, install the K-104 / K-114 driver on your computer and then run the K-114_Config software. (The software can be downloaded free of charge at www.keller-druck.com) Running the K-114_Config software Run K-114_Config and select the appropriate COM port. Then go to the K-114 Configuration view (top right). Tip: When the program is open, Comport is selected automatically as soon as the K-114 is plugged into the computer. 24 Voltage and current measurements with K-114_Config No. Symbol 1 I-OUT 2 U-USB 3 U-OUT 4 U-IN Function Current supply external consumer USB voltage supply Voltage supply external consumer Voltage input Description No valid display during operation with external current supply Switched-in voltage supply is indicated via U-OUT Range: 0...12 VDC 25 Warnings and other messages in the software U-USB is below minimum This message appears if the U-USB voltage is below 4,8 VDC. Fault-free functioning of the converter is no longer guaranteed. Supply the converter from an external power supply unit. U-OUT outside of range This message appears if U-OUT is less than 11,2 VDC. Supply the converter from an external power supply unit. 26 U-IN outside of measurement range The U-IN measurement range is from 0...12 VDC. The exclamation mark warns you that the upper limit of the measuring range that can be displayed (> 16 VDC) has been reached. The voltage for measurement that is actually applied (U-IN) can therefore be greater than the value for U-IN that is displayed. Connect power supply unit If the difference between U-OUT and U-IN is less than 3 VDC, the «Connect power supply unit» message appears. Getting support If faults or errors occur while you are working with the converter, use the Help with fault analysis section to rectify the problem. If problems persist after you have worked through this section, you can request assistance from KELLER by telephone.

Once the download has completed, run the program. After you enter the connection code, our technical support team will log into your computer and offer you on-the-spot help directly on your screen. 27 Recording K-114 measurement data The values measured for I-OUT, U-IN, U-OUT and U-USB can be recorded and saved via Software ControlCenterSeries30 (CCS30). (Read the CCS30 manual on this subject.) To view the K-114 controller's measured values via the software, you must enter bus address 253 in the CCS30 and let the device search. Use the «New measurement» function key to view and save the measurement data. 28 Konformitätserklärung Declaration of Conformity Déclaration de Conformité Für das folgende Erzeugnis Herewith we declare, that the following product Nous attestons que le produit Konverter K-114 Converter K-114 Convertisseur K-114 wird hiermit bestätigt, dass sie den Anforderungen folgender EU-Richtlinien EMV-Richtlinie 2014/30/EU RoHS-Richtlinie 2011/65/EG unter den Bedingungen · Kabellängen kleiner 3 m · Nutzung innerhalb von Gebäuden entspricht.
