Device Selector

Kipling provides an intuitive way to connect and control multiple devices. After refreshing the device listing Kipling graphically displays all of the found and compatible LabJack devices in an easy to understand manner while providing some useful information to the user for debugging possible connection issues. Each device's model, serial number, user defined name, Ethernet IP address (when applicable), WiFi IP address (when applicable), and WiFi signal strength (when applicable) are displayed for easy viewing.

Scanning for Devices

The scanning process can take 60+ seconds when searching for devices connected over WiFi and if the device's WiFi connection is week, packets can get dropped and multiple retries may occur trying to collect information about the scanned device. Because of this, K3 exposes the option to select what interfaces should be used to search for devices. LJM can selectively scan for devices connected over USB, Ethernet, and WiFi. If you are having issues getting a device connected over Ethernet/WiFi or trying to debug your network connection issues the following two Networking App-Notes are useful to look at:

Select your devices

Press the green USB/Ethernet/WiFi buttons to connect to devices using that connection type. Select any number of devices in this manner. If a device was selected on accident, simply press the disconnect button.

Connection Buttons and Colors

After searching for a device the device connection type buttons that allow users to connect to a device are sometimes different colors.

The USB, Ethernet, and WiFi device connection buttons can be either green, yellow or red. The colors indicate the following:

  • Green: The connection type for a device was successfully found using the LJM_ListAllExtended function call and the device's connection was successfully verified by opening and closing the device using the LJM_OpenS and LJM_Close function calls.
  • Yellow: The connection type for a device was not found using the LJM_ListAllExtended function call however when opening the device to verify the connection type and collect extra information from the device it was discovered that the device has a valid Ethernet IP address (not 0.0.0.0) or the WiFi status register reported that it was connected with a valid IP address. Using the device attributes Kipling was able to successfully verify the connection type by opening and closing the device using the LJM_OpenS and LJM_Close function calls.
  • Grey: The connection type for a device was found using either the LJM_ListAllExtended function call or the device's attributes however when trying to verify the connection type the LJM_OpenS function returned an error (non zero value).

During the scanning process and after a user clicks one of the connection type buttons Kipling uses the LJM_OpenS function call with the parameters listed below to connect to devices.

Device Type Connection Type Identifier
"T4" or "T7" "USB" [device serial number]
"T4" or "T7" "Ethernet" [device IP address]
"T4" or "T7" "WiFi" [device IP address]
