INSTALLING THE PC/104 AO MODULE OPTION
The first PC/104 AO Module is to be mounted directly above the FMI/OB Board as
illustrated in Figure 3.
Installing a PC/104 AO Module
Follow steps 1 through 6 below to install the PC/104 AO Module.
1. Disconnect power from the ControlWaveLP (Shut down or place under manual
control any critical processes prior to disconnecting power).
2. Align the PC/104 AO Board’s PC/104 Bus Interface Connectors J1 and J2 (on the
bottom of the PCB) with FMI/OB Board Connectors P1 and P2 respectively and
press the PC/104 AO Board onto the FMI/OB Board.
3. Set the PC/104 AO Board Jumpers (see Topic - Setting the PC/104 AO Board
Jumpers) and set the AO Board Address via Switch S1 (see Topic - Setting the
PC/104 AO Module’s I/O Memory Map).
4. Secure (screw) the PC/104 AO Board to the appropriate standoffs (4) on the FMI/OB
Board (see Figure 2 - standoffs labeled A and see Figure 3) with four new standoffs
(to accommodate an additional PC/104 AO Board or the PC/104 Display/Push-button
Control Board).
5. If one, two or three additional PC/104 AO Boards are to be installed align the
PC/104 AO Board’s PC/104 Bus Interface Connectors J1 and J2 (on the bottom of the
PCB being installed) with PC/104 AO Board Connectors P1 and P2 (on the top of the
unit previously installed), and press the PC\104 AO Board into place. Repeat steps
4 and 5 up to three times.
6. Connect field wiring to Connector TB5, TB6, TB7 and/or TB8 as required (see Topic -
PC/104 AO Board Field Wiring
).
Setting the PC/104 AO Board Jumpers
PC/104 Analog Output Boards contains 6 Jumpers that are defined in Table 1.
Jumpers JP1 through JP4 are provided with two (2) two-position Jumper Blocks. If only one
Jumper Block is used, as is the case when the PC/104 AO Board has been configured for 4-
20 mA operation, the other Jumper Block should be stored on post #1 or #4 of the Jumper in
question.
Jumper JP6 can be used to select either the Power Supply/Sequencer Board or an external
supply as the source of power for the PC/104 AO Board’s analog outputs. There may be
times when the user elects to operate the RTU while the PC/104 AO Board is shutdown or
continues to power the PC/104 AO Board while the CPU is in low power or shutdown state.
When the Jumper Block associated with JP6 is installed across pins 2, 4, 6, & 8 the PC/104
AO Board will be powered from an external source.
