3 Function of the Ethernet Cable Guard
The Ethernet Cable Guard enables the service life monitoring of Ethernet data cables (100Base-TX) with a focus on dynamic applications in automation technology, such as a drag chain cables to moving machine parts (robots). With the Ethernet Cable Guard, system availability can be increased, and downtimes can be planned. This enables a significant reduction in maintenance costs.
The Cable Guard is looped into the cable harness to be monitored and can provide information about the quality of the cable connection via a status LED, a separate network connection or a digital output. The feedback can be displayed as a PWM signal at the output. The alarm limit value can be set individually ("lifetime" 99 - 50 %).
For integration into IIoT structures, the monitored cable status can also be sent via MQTT by the Cable Guard. The particularly compact design is suitable for use in decentralized control cabinets and can be mounted on standard DIN rails. The Cable Guard is also suitable for EtherCAT, EtherNet/IP and 2-pair PROFINET applications.
4 Connection
4.1 Power supply
The Cable Guard be supplied with DC 24 V at the wide-range input DC 18 ... 28 V via the supplied connector plug.
The housing of the Cabel Guard is not grounded. Please connect the functional earth terminal ("FE") of the PN/PN Coupler properly to the reference potential.
The device is intended to be supplied by an isolated Limited Energy Source according to UL61010-1 (3rd ed cl. 9.4) or according to UL60950-1/UL62368-1 or Class 2 according to NEC. Please use Cu power supply wires, AWG 28-12. Maximum length of removed insulation is 10 mm. Temperature cable rating is 87 °C.

4.2 Network
The Cable Guard has two "DATA" RJ45 connections for the link to be monitored. The cable to be monitored (e.g. a drag chain cable) must be connected to the lower connection ("Guard"). The upper DATA connection should then be connected to the communication partner (e.g. the control unit) using another standard industrial Ethernet cable. The Cable Guard is thus looped into the cable to be monitored via these two connections.
The cable measurement is carried out at the lower "Guard DATA" connection over the entire cable (minimum length 2 m) up to the connected communication partner. The Cable Guard does not change the content of the data transmission between the DATA connections.
Data transmission between the two DATA connections only works if the Cable Guard is supplied with power and is in normal operating mode! The left RJ45 Ethernet socket "LAN" is used to connect a TCP/IP network for accessing the web interface and sending MQTT messages.
5 Initial commissioning
Please connect the device to the power supply. Please also note the information above on using the functional earth (FE). As soon as the DATA connections are connected via Ethernet cables and the links are in place (see ports of the RJ45 connections), a teach-in must be carried out for the device to function correctly (this also applies to any cable replacement). To do this, press the SET button for 20 seconds. As soon as the PWR and STATUS LEDs light up red continuously, the teach-in is started. Now release the SET button. The PWR LED now lights up green and the status LED flashes green, the teach-in is carried out and the cable is now calibrated. Once the teach-in process is complete, the PWR and STATUS LEDs light up green continuously. This is the normal operating status of the device. Monitoring of the cable is now active. The teach-in values are permanently stored in the device and are retained even in the event of a power failure or a firmware update (software update). The teach-in process is only necessary after reinstalling the Cable Guard or after replacing the cable.

The status of the line is displayed via the STATUS LED: Green = The cable is OK Flashing red = Maintenance of the cable is required (plan replacement) Permanently red = The cable is defective
Data transmission between the two DATA connections only works if the Cable Guard is supplied with power and is in normal operating mode!
Further configuration and more information about the status of the Cable Guard can be found on the device's website.
If the Cable Guard is restarted after a teach-in or if there has been a power failure, the measurement takes a few seconds until a measured value is available again. This is indicated after the restart by a green flashing STATUS LED (initialization).
5.1 Display of the operating statuses via the LEDs
Ready for operation & Line is OK: PWR and STATUS are permanently green
Teach-In / Initialization: PWR is permanent green STATUS flashes green
Maintenance required: PWR is permanent green STATUS flashed red
Cable defective: PWR is permanent green STATUS is permanent red
No teach-in performed: Only PWR is green
Teach-in faulty: PWR flashes alternately red/green

6 Website
6.1 Access to the website
Connect the LAN interface of the Cable Guard to your PC using a standard Ethernet cable. When accessing the website for the first time, set your PC interface to the appropriate subnet, e.g. with the IP address 192.168.0.1 with subnet mask 255.255.255.0 for LAN access. Open the website in a current browser with "https://192.168.0.32".
For security reasons, the web interface can only be accessed via a secure HTTPS connection. To access the website, an exception rule may need to be confirmed in the browser. In the "Settings" menu, you can store your own certificate for securing the connection if required. When you log in for the first time, you will be asked to set a password for the default user "admin". The password must be at least 8 characters long.
Please memorize the password well! For security reasons, there is no way to reset the password without resetting the device to factory settings.
6.2 Main view
After logging in, the Cable Guard "Home" website always opens. The main view contains information about the device and cable status. The menu on the left-hand side contains additional functions for further configuration or firmware updates For further information on the configuration options, please refer to the manual.

6.3 Firmware Update
The firmware update can be accessed on the web interface via the "Update" menu item. The current firmware version is displayed and a new firmware can be uploaded to the device using the "Browse new firmware file" button. The Cable Guard saves the firmware file in its internal memory. After the device is restarted, the firmware is checked. If the content is correct, the firmware is used, otherwise the device is restarted with the old firmware.
Operation of the Cable Guard is interrupted during the update process. Data transmission between the two DATA connections is interrupted during the update. Do not switch off the device during the update process! Switching off the power supply can destroy the device. All settings, the teach-in values and the current measurement of the cable are not changed by the firmware update.
6.4 Factory Reset
The Cable Guard can be reset to factory settings using the "SET" button when the device is switched on. When the Cable Guard is reset, the complete configuration and all measurement data are irretrievably deleted and IP settings are reset to the factory settings. The firmware remains up to date. To activate a reset to factory settings, disconnect the Cable Guard from the power supply. Now press and hold the SET button and switch the power supply back on. After 8 seconds, the PWR LED flashes alternately red/green. Now release the SET button. The factory reset is now performed, and the Cable Guard then restarts.
