Are the SMM's interchangeable between the HI 2151/30WC and the HI 2110WI?

Can I remove the SMM from my HI 2151/30WC and place it into a HI 2110WI spare unit and have it work with all the HI 2151/30WC settings and calibrations?

No, you cannot remove the Secure Memory Module (SMM) from your HI 2151/30WC and place it into a HI 2110WI spare unit and have it work with all the HI 2151/30WC settings and calibrations. The HI 2151/30WC has formatted options the HI 2110WI does not have.

Even though you cannot swap the formatted SMM from the HI 2151/30WC to the HI 2110WI, the SMM modules themselves ARE interchangeable between the HI 2151/30WC and the HI 2110WI. It is the same part. (0519-0512-06)  You would just have to erase the SMM and re-enter calibration data.

Erasing the SMM uses the clear memory procedure.  Search for RAM clear instructions in the WebTech Knowledge base.
