Hi, I'm trying to make a DIY 404b tacho cable using Emerson CSI devices. I found a 20 kOhm resistor between two terminals and connected it to a 5-pin and 3-pin connector, but the LED blinks irregularly. Can someone help?

It might be a grounding issue. Ensure all connections are secure and check the resistor values again.

Have you tried using a different LED? Sometimes, the LED itself can be faulty.

Double-check the wiring diagram for your CSI device. Sometimes a missed connection can cause erratic behavior.

Make sure that the power supply you are using is stable and provides the correct voltage for the device.
