A mass data acquisition system utilizes a recorder that is provided with both CMOS RAM (18) and a removable memory cartridge (28). The memory cartridge can be used to transport data from the recorder to a translator (32). Furthermore, the CMOS RAM is used to store the data records formulated during an entire recording period. When operated in the RAM mode (28-out), all data is stored in the CMOS RAM and the data cartridge is used only for purposes of transporting data to the translator. When operated in the cartridge mode (28-inserted), all formulated data is stored in both the CMOS RAM and the cartridge. This cartridge mode of operation provides redundancy and serves as a backup dual memory system to prevent loss of data in the event that a memory malfunction occurs in either one of the two memory media. The recorder can also communicate with a translator (32) over phone lines (38) in conjunction with serial I/O (34) and a MODEM (36). When communicating with a translator on the phone line, data can be obtained from either a cartridge, when in the cartridge mode, or directly from CMOS RAM when in the RAM mode. |
