When it may not be suitable

This cable is specifically designed for 3RC7 ILM modules and may not be compatible with other communication protocols or hardware interfaces. It is not intended for applications requiring long-distance data transmission due to its fixed 0.75-meter length.

Key specifications

How to use

To use the cable, ensure that the power to the 3RC7 ILM modules is disconnected before installation.

Once connected, verify the physical integrity of the link and restore power to the system to initiate communication between the modules.

What to consider before purchase

Verify that your specific hardware is part of the 3RC7 ILM series
Ensure the 0.75-meter length is sufficient for your module spacing
Check for proper cable routing to avoid sharp bends or mechanical stress
