As requested by the 4th EMU meeting in late 1994, Metsahovi provided an additional AEC/NIM subrack / module bin for each of the participating five EVN stations. The subrack is not part of the original contract and will be invoiced separately. The rack was not requested by NASA JPL for their recorder upgrades, so none have been supplied.
We have used ``MECH-TRONICS'' Type 150 NIM Bins which come without NIM backplane and connectors. This crate is for fitting the existing inchworm controller module(s) in a new location inside the recorder rack, as explained in the installation instructions. The existing subrack is reused for the upgrade modules.
