PIM2 PULSE INPUT MODULE 2 The Pulse Input Module 2 (PIM2) provides four channels of 16 bit or two channels of 32 bit event counting with channel-to-channel independent totalizing capability. All counters (one per channel) are independently readable and resettable. Each input channel is provided with a separate gate input. These gates allow the event inputs to be configured as four dual input channels to allow the input events to be gated by other external sources. Input events cap be counted at speeds of up to one million pulses per second. Con- catenation of counters allows for counting of over four billion (4 x 109) events. Anti-coincidence circuitry ensures that the counters are not read in an undefined state. Software control selects input channel and channel to be reset. Signals are connected directly to the module via on-card quick disconnect terminals. Installat ion Series 500 system: The PIM2 module may be placed in any available slot in the Series 500; however, digital modules should generally be placed in the high-numbered slots if any analog modules are present in the system. To install the module, remove the baseboard top cover and insert the module into the desired slot with the component side facing the power supply. CAUTION: Always turn off the baseboard power before installing or removing modules. Replace the top cover and secure it with screws. To avoid the possibility of EM1 radiation, never operate the system with the top cover removed. System 570: The System 570 can accept one PIM2 module in its option slot. To install the module, position it so that the cable strain relief is towards the rear of the unit; insert the card edge into the guide and carefully slide the card into the option slot. Document Number: 501-909-01 Rev. B l?IM2-1 CAUTION: Always turn off the power to the 570 mother board before installing or removing modules in/from the option slot. To avoid the possibility of EMI radiation, never operate the system with the top cover open. For either system, update the software configuration table to show the location of the PIM2. User-Configured Components See Table 1 and Figure 1 for a list of user-configured components and their locations on the PJM2 module. Switch 1 (Sl) selects between separate 16 bit operation of counters 0 and 1, or con- catenation of these two counters (32 bits). Switch 2 (52) selects between separate 1s bit operation of counters 2 and 3, or concatenation of these two counters (32 bits). Each of the four segments of switch set 3 either connects or discon
