The K-TC is Influx’s stackable instrumentation compatible with the entire range of data loggers from Influx. It can also be integrated with any device configured via DBC files, even other logger systems or output signals on CAN to the Rebel Dash display.

The K-TC is an ideal solution for applications that require a large number of thermocouple inputs. The K-TC’s accurate sensor data is transmitted periodically on the CAN bus, enabling multiple devices to be connected. In addition, the K-TC CAN bus settings, calibration, and sampling rates are all easily configurable, and these settings are stored within the K-TC 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:

C:\Program Files (x86)\Influx Technology\Influx K-Cal\TCxxDriver

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.

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 simple as possible.

Most commonly, it will be powered from a Rebel Logger using the Multi Connect Cable, 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 to allow the Logger to record the data transmitted from the K-TCxx.

The pinout of the required Cable between the two K-TCxx is as follows:
