TA705 Data Retention Chassis operating manual
The Data Retention Chassis (DRC) is a data acquisition component based on the Motorola 68000 microprocessor. The purpose of the DRC is to download the correct set-up parameters into sixteen Tektronix 7912 digitizers, to verify that the digitizers retain their settings, and (once the digitizers have triggered) to load that data into the DRC battery back-up CMOS memory. The DRC also has a circuit built into it called the COMMAND LINK. With the help of the TA698 Alternate Common Equipment (ACE), the user employs this link to communicate interactively with the digitizers and the DRC. Another circuit built into the DRC is the data stream multiplexer (DSM) for high-speed data transfers.
