Honeywell USB cable DI100001

The Honeywell DI100001 is a USB cable designed for use with Honeywell Maxsys boiler controllers, specifically models S4966V2029 and S4966V2045. It carries low-voltage data and power signals between the control board and external programming or diagnostic tools. The cable features a USB connector type and includes shielding to maintain signal integrity. It is categorized under cables and is identified by SKU DI100001.

Parts of this type are selected by matching the connector style (e.g., USB-A, USB-B, or proprietary mini-USB) and the required cable length to reach the service position. Verify that the connector profile matches the port on the control board, which is typically a recessed micro-USB or rectangular USB-B socket. The original cable length serves as a safe guide for replacement.

A damaged cable or poor contact at either end can prevent communication, causing the service tool to report a 'no connection' error even if the control board is functioning. Check the cable for physical damage and ensure both connectors are securely seated.
