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 congured using the „K114_Cong“ 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 visi-

ble 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.

● The virtual COM port numbers generated can be found by navigating to „Devices and Printers“ /

„K-114 BT SNxxxx“.

Right-click on the logo under „Properties“ / „Services“ to nd the generated COM port.

➞This procedure need only be completed once. The generated virtual COM port remains available for further

sessions. In other words, as soon as this port is accessed, the BT connection is established automatically.

USB

General

In order to operate the interface converter via USB, the interface driver „Driver K-114“ must rst be installed on

the computer. The driver software is included on the KELLER software CD and can be downloaded for free from

www.keller-druck.com.

Communication

If the device is connected via Bluetooth, any communication via the USB interface is automatically interrupted. Once

the Bluetooth connection is deactivated, it is again possible to communicate via the USB interface.

Pairing/connecting via Bluetooth for the rst time

The computer must have an internal Bluetooth module or a Bluetooth USB dongle (Bluetooth Classic 2.1 or higher)

● To establish a Bluetooth connection with the K-114 BT, open the window „Devices and Printers“

in the Control Panel.

➞Ensure that the K-114 BT converter is switched on (Power LED is illuminated).

●

Click on

„

Add a device

“

to search for Bluetooth devices. This may take a few minutes. The K-114 BT converter

with the correct serial number should appear in the list.

➞ The computer may not nd the converter on the rst attempt. If this happens, please check that the converter is

switched on and is not too far away from the computer.

●Double-clicking on the converter symbol opens a new window with the automatically generated

coupling code. Click on „Next“ to couple the K-114 BT converter with the computer. A virtual COM port is now

created that can be used to communicate with the connected device.

Battery/charging

In order to protect the battery in the device, the user should switch off the converter after use. In battery operation,

the K-114 BT switches off automatically after communication has been inactive for 30 minutes.

The battery can be charged via the USB interface. Care must be taken to ensure that the battery can be charged

both via a normal USB port and a DCP (dedicated charging port) or USB adapter. This has the benet that instead

of being charged with 500 mA or 100 mA (USB port), the battery can be charged with up to 1 A (DCP), reducing

the charging time.

RS485 interface

For Bluetooth communication and the internal controller (bus address: 253), the converter supports the baud rate of

9600 baud (default) or 115200 baud, 8 data bits, 1 stop bit and no parity. This transmission speed must be congu-

red on the master (PC) and on the K-114 BT.

Parity Odd, even, mark, space, no parity Yes

The K-114 BT converter communicates with the connected devices via an RS485 (half-duplex mode) bus. The

internal battery supplies power to the devices connected to the K-114 BT. KELLER products operate with fail-safe

drivers, which output a logical high at the receiver outlet in the event of short-circuited, open or non-terminated

inputs in order to avoid invalid signal states. KELLER products also feature slew rate limitation, which limits the edge

steepness of the driver output. This prevents high-frequency emissions from devices and data lines. A maximum of

128 bus devices can be connected to this RS485 master.

Software K-114_Cong

The software K-114_Cong is a conguration and diagnostic tool for the converter K-114 BT. It can be used to

congure the baud rate of the converter, as well as to select the echo function and to switch on the bias resistors or

the termination resistor. If an end consumer is connected, a full diagnostic test can be run to determine the power

consumption and applied signal voltage and a communication test can be performed.

Installation

First, install the K-114 BT driver on your computer, then launch the K-114_Cong software. (Software CD included

in scope of delivery or available as a free download from www.keller-druck.com)

Execution

Launch the program "K-114_Cong" and select the corresponding COM port. Then navigate to the K-114 congu-

ration view (top-right of the tab).

– 34 – – 35 –

The function „Download remote maintenance software“automatically begins the download of a remote desktop

program. Launch it once it has downloaded. After sending a connection code, our technical support team will log

into your computer and provide help directly on your screen.

Error analysis/support

If problems arise when using the converter, please refer to the chapter „Error analysis support“for help. If the

problem persists after you have followed the instructions in this chapter, please contact www.keller-druck.com

Warnings and messages in the software

The following warnings and messages in the „K-114 Cong“ software notify the user that an invalid state has arisen.

The message is displayed in the top line of the window „K-114 Conguration“.

Battery almost empty

If the charging capacity of the battery drops below 20%, the user is notied that the battery is low on power.

Battery low, connect charger

This nal warning appears when the capacity drops below 10% and instructs the user one last time to charge the

device before it switches off automatically.

U-OUT outside of range

This message appears if the voltage U-OUT is less than 14,25 VDC. As an initial measure, remove the external

devices until the error disappears.

Short circuit/overload at output

This message appears if the output current I-OUT exceeds 125 mA. This indicates that the load is too high: please

check the power supply connection. As an initial measure, remove the external devices until the error disappears.

U-IN outside of measurement range

The measurement range for U-IN is 0…12 VDC. The message informs the user that the upper limit of the measure-

ment range that can be represented (> 15VDC) has been reached. The measurement voltage U-IN actually applied

may therefore be greater than the displayed value.

– 36 –

Recording K-114 BT measurements

The measurements I-OUT, U-IN, U-OUT and U-BAT can be recorded and stored via the software ControlCenter-

Series30 (CCS30). Read the CCS30 manual to nd out more about this.

In order to display the data for the K-114 controller using the software, you must enter bus address 253 in CCS30

and start the search for the device. You can display and store measurements via the „New measurement“ function.
