Selection Guide
Use the following criteria to confirm MC-ZLLMF2 is the correct upgrade kit for your application:
- Step 1 — Identify your LLMUX IOP hardware revision: Check the module label for the hardware revision code (e.g., Rev C, Rev D).
- Step 2 — Confirm your DCS platform version: Experion PKS R400+ or TDC 3000 LCN/UCN version.
- Step 3 — Match firmware revision: MC-ZLLMF2 corresponds to firmware revision F2. If your system requires F1 or F3, select MC-ZLLMF1 or MC-ZLLMF3 accordingly.
- Step 4 — Verify upgrade procedure: Confirm whether an online or offline firmware load is required for your site.
- Step 5 — Contact Konmask: Send your system details to support@konmask.com for a free pre-purchase compatibility verification.

Replacement & Compatibility FAQ
Q: Can MC-ZLLMF2 replace MC-ZLLMF1?
A: In most cases yes, as F2 is a later revision. However, confirm with your Honeywell system engineer or contact Konmask before substituting.
Q: Is this a hardware module or a firmware kit only?
A: MC-ZLLMF2 is a firmware upgrade kit — it updates the firmware on an existing LLMUX IOP hardware module. It does not replace the hardware itself.
Q: Do you offer the LLMUX IOP hardware module separately?
A: Yes. Contact us for part numbers such as 51304485-100 or equivalent LLMUX IOP boards.
Q: What warranty is provided?
A: 12-month warranty on new units; 6-month warranty on surplus/refurbished units. See our warranty policy for details.
Q: Can I use this firmware kit on a non-Honeywell DCS?
A: No. This firmware is proprietary to Honeywell LLMUX IOP hardware and is not compatible with third-party DCS platforms.
