Q: Can I use the HIMA F3236 as a direct replacement for the F3230?
A: Not directly — the F3230 has 8 channels vs. 16 on the F3236. You must update your I/O configuration in SILworX and verify rack slot assignments.
Q: Is the F3236 compatible with older ELOP II projects?
A: Yes, with appropriate hardware revision matching. Consult HIMA’s compatibility matrix or contact our technical team.
Q: Do you supply new or refurbished units?
A: We supply both new and tested-refurbished units. Condition is clearly stated on each listing. Contact us if you require new-only supply.
Q: Can I get a datasheet or certificate of conformity?
A: Yes — request documentation at support@konmask.com with your order reference.
Q: What is the lead time for the HIMA F3236?
A: Typically 1–5 business days for in-stock units; 2–4 weeks for sourced orders. Contact us for real-time availability.
