CI-ControlWaveLP Appendix 1  Page 5  PC-104 AO Module Option 
Jumper JP7 provides for selection of either a 6 MHz Oscillator or the 6 MHz System Clock 
as the clock source for the PC/104 AO Board. The 6 MHz System Clock should be used when 
it is desired to shut down or slow down the clock during low power periods, i.e., when the 
CPU has been placed into power down or low power mode.

Setting the PC/104 AO Module’s I/O Memory Map 
Switch S1 on the PC/104 AO Board is used to set the AO Board’s Slot Address above B000 
at the address boundaries defined in Figure 5. Switch selections 0-5, E and F are ignored. 
PC/104 AO Board Field Wiring 
PC/104 AO Boards are interfaced to the analog field devices through FMI/OB Board 
Connectors TB5 - TB8. The relationship of TB5 - TB8 to the PC/104 AO Board is 
determined by the 40-pin FMI/OB Connector (P3, P4, P5 or P6) to which the PC/104 AO 
Board in question has been interfaced. Table 2 - provides the relationship of PC/104 AO 
Board Connector P3 and FMI/OB Board Connectors P3, P4, P5 & P6 to FMI/OB Board 
Connectors TB5, TB6, TB7 & TB8. 
Field wiring supports 4-20 mA AOs (see Figure 6) and 1-5 V AOs (see Figure 7). +(9 to 30) 
Vdc power is available to power up to four analog field devices (see Table 2 and Figures 6 
and 7).
