On power-up this unit will respond like a SLAC IDIM. The following enhancements were made: o An edge progamable latch register on each channel o Programable digital filter on each channel o Programable threshold on each channel o Programable test on each channel o Module ID and serial number register o Channel/Module lock feature for Machine Protection System (MPS) functions o MIL 1553 port for MPS functions o Cable Monitor function

19.1.3.1 IDIM Mode (Power on default) - o "0" = -30 through +1 volts, o "1" = +3 through +30 volts. o (Undefined from +1 volt to +3 volts.)

19.1.3.2 High threshold Mode - o "0" = -30 through +9 volts, o "1" = +11 through +30 volts. o (Undefined from +9 volt to +11 volts.)

19.1.3.3 CMON - o "0" = -30 through +1 volts, o "1" = +3 through +30 volts. o (Undefined from +1 volt to +3 volts.)

19.1.4 Input Optically isolated with current drawn not to exceed 10 milliAmps at 30 volts in.

19.1.5 Latching Data available both latched and nonlatched. During a CAMAC read cycle the data is held.

19.1.7 CAMAC Codes, X and Q Responses All registers are lockable on an individual channel basis. Data written to a locked channel will be ignored if the module is also locked. If the module is locked, all write operations return Q=0 however, data is written to unlocked channels. If the module is unlocked, data is written independent of the channel lock status.

19.1.7.1 Read Functions - o F0A[0..1] --- Read Channel Data Register; X=1, Q=1 if +24volts OK.

19.1.9 MPS PORT The Machine Protection Port (MPS) is a subset of the MIL 1553 protocol. The LDIM responds only to the four functions listed below. The first two data words are the unlatched data (or test data). This is the same data that is read out through CAMAC using F0A[0..1] command. The third and fourth data words are verification pattern words 5555\H and AAAA\H.
