MODEL DTM-399 (Enhanced Version)
-Power supply failure detection
-Ambient temperature monitor


This series of Dataway Test Modules is designed for use as a low-cost diagnostic, test and display aid for troubleshooting CAMAC, from both a hardware and sottware viewpoint. Status and dataway conditions can be seen at a glance, also computer controlled systems can run self diagnostics through to the dataway level. (Confidence factor for system programmers)!

Front panel LED indicators display the status of all dataway signals in either Latch or Track (continuous) mode. Write data, control signals, and status for the previous dataway operations may be read back for system self diagnosis. A front panel manual LAM switch is also available to test the crate and software LAM handling capability.

In addition to these features the MODEL DTM-399 includes monitoring of ambient temperature and the four standard CAMAC power supplies. Should a preset limit be exceeded by high ambient temperature, a voltage failure, current spike or power supply oscillation a LAM will be generated. The detection and logic circuitry is powered by voltage steering and any supply may fail without affecting the modules operation.



NA[O]F[O]  Read data       Q,X = 1
   Reads previously Latched write data onto Dataway
   read linds.  Rl-R24

NA[O]F[l]    Read status    Q,X = 1
   Reads previously Latched  status, function code,
   subaddress, etc. onto Dataway read lines, plus
   reads position status ot front panel switch.
