The K-TC 2.0 is Influx's upgraded version of the older K-TC modules. Like the previous modules, these are stackable instrumentation devices compatible with Influx's entire range of data loggers. These can also be integrated with any device configured via DBC files, other logger systems, or output signals on CAN for the Rebel Dash display.
The K-TC 2.0 is an ideal solution for applications that require a large number of thermocouple inputs. The K-TC 2.0's accurate sensor data is transmitted periodically on the CAN bus, enabling multiple devices to be connected. In addition, the temperature data is simultaneously logged in the inbuilt micro-SD card (8GB), the K-TC 2.0 CAN bus settings, calibration, and sampling rates are all easily configurable, and these settings are stored within the K-TC 2.0 even when the device is not powered.

Before proceeding with the installation, please ensure you have acquired administrative privileges.
To install the K-TCxx driver, run the .exe file in this location:
The .exe file can also be found in the start menu under ‘influx technology.
Run the K-TCxx Installer.exe file.
Click 'Next' to continue installing the K-TCxx device driver on your system.
To cancel the installation at this stage, click ‘Cancel’. (No software has been installed on the system at this point.)
Please read the license agreement carefully.
Once you understand and accept the license agreement, please click ‘I accept this EULA’ to continue with the driver’s installation. If you do not accept the terms, please click ‘Cancel’ to stop the installation at this point.
Click ‘Next’ to continue the installation process.
Once the installation is complete, this window will appear.
Click ‘Finish’ to close the window. The K-TCxx driver is now successfully installed on your system.
However, K-TCxx is powered via the CAN and power connectors and designed with CiA® 102 pinout for the CAN bus and power to connect the device as simply as possible.
Most commonly, it will be powered from a reXgen Air or a Rebel Logger using the Multi Connect Cable or via ReXgen 1/2/IMU via its connectors, but you can also power it via pin 9 (4.5 to 36V) and pin 5 PowerGND of the 9-pin Sub D connectors. If connected via the multi-connect cable, the CAN 1 (MS) bus is also connected, allowing the Logger to record the data transmitted from the K-TCxx.
When using a ReXgen Air device with K-TC, be sure to get in touch with the technical support team at influx.
b) Setup for interfacing Rebel Device to K-TC
Warning:
Several K-TCxx can be daisy chained via the additional DB9 Connector. However, they must have power supplied separately via power breakout in the cable, not via the Logger. It can also connect to other devices, such as the Rebel Dash.
The pinout of the required Cable between the two K-TC 2.0xx is as follows:
The ‘Interface Tab’ is situated at the top of the software screen and can navigate most program features. Some of the menus will be active only when a logger is interfaced.

Once the K-TCxx is configured as you wish to use it and have generated a DBC file that describes its configuration, you may load that description file into DiaLog and use it to configure the Logger to record the data output by the K-TCxx.
If you power it from the Logger, it will need to be powered from the vehicle or an external power source (NOT just via USB), and you will need to make sure the AUX power feature in the configuration is set to on. To do this, follow the Steps Below:
Open DiaLOG, Right-click on a project with CAN 0 HS bus, and select 'Properties.
Once the Edit Configuration window is displayed, click on the 'Settings' Tab and put a Checkmark in Aux Power On; Click OK.
Select the sleep mode suitable for you; it is recommended to use the following:
Wake On CAN 1 or Wake On CAN 0/CAN 1 or Power Down mode.
Create new BUS
Select the hardware type (CAN 1 MS) from the popup menu.
Enter the BUS properties.
Create New Protocol.
Select the CAN Monitor protocol.
Assign the settings and protocol name.
Select the import tab and click load DBC.
Click the DBC tab on the right side.
Select the required signal from the DBC window.
Copy the selected signals and paste them into the DAQ list.
Send the configuration to the Logger.
Once you launch the K-TCxx Configuration utility, you will see the settings for the Interface you are using. If the K-TCxx is on and connected, its serial no and firmware version will be displayed at the bottom of the screen.
If the device is not interfaced, choose the interface device and click Baud Rate Scan.
Using the DBC Export Feature allows you to export the Conversion tables and Formulas Applied to the various Analog channels for use in other tools such as DiaLog.
Select the channels you wish to include in the DBC and click Export.
Choose the location where you wish to save the DBC file.
Clicking DBC Export will open the DBC export window.
