Abstract
Abstract An apparatus for servicing a removable RAM package of an ambulatory medical monitor is disclosed. The RAM package comprises a RAM for storing blood pressure data and operating parameters and a real time timer. Both are coupled to a multipin edge connector by parallel multibit data and address buses. An adapter for servicing the RAM package by a scanner controller through a standard serial interface is provided. The adapter comprises a microcomputer chip coupled between an RS-232 serial interface and a multipin edge connector for mating engagement with the edge connector on the RAM package. Servicing includes writing and reading data from the RAM package, and reading and setting the time in the real time timer. The apparatus further includes means for controlling access to the adapter by the scanner controller using an identification and unlocking scheme. The system will not unlock if a RAM package is not coupled to the adapter.
