The 18203 is restricted from view to all but Campbell Scientific employees. This version of the CR1000-4M was for OEMs. It did not have a label so that the OEM could attach their own branding. The 18203 was offered when the standard CR1000 had 2 Mbytes of data/program storage. In September 2007, the standard CR1000 started having 4 Mbytes of memory—making the CR1000-4M as well as the 18203 obsolete.  Replacement parts remain available (see Ordering Info).
