What type of connector is required to connect the communications cable to monitor or program the VFD with an external PC?

Explanation:
A local PC connection to a VFD’s programming or monitoring port uses a dedicated serial interface that relies on an RJ-11 modular connector. This small telephone-style plug is the standard for the manufacturer’s programming cables, carrying the needed RS-232/RS-485 signals for direct PC communication with the drive. USB, RJ-45, and HDMI serve different purposes: USB would require a USB-capable port on the drive, RJ-45 is for networked communication rather than a direct PC link, and HDMI is for video output only. So the connector you need for that direct programming cable is RJ-11.
