Manual 104-QUAD-8 

Installing the Hardware

 

Before installing the board, carefully read Chapter 3 and Chapter 4 of this manual and configure the 
board according to your requirements. The SETUP Program can be used to assist in configuring 
jumpers on the board. Be especially careful with Address Selection. If the addresses of two installed 
functions overlap, you will experience unpredictable computer behavior. To help avoid this problem, 
refer to the FINDBASE.EXE program installed from the CD. The setup program does not set the options 
on

 the board, these must be set by jumpers. 

 

To Install the Board 

1. 

Install jumpers for selected options and base address according to your application 
requirements, as mentioned above. 

2. 

Remove power from the PC/104 stack. 

3. 

Assemble standoff hardware for stacking and securing the boards. 

4. 

Carefully plug the board onto the PC/104 connector on the CPU or onto the stack, ensuring 
proper alignment of the pins before completely seating the connectors together. 

5. 

Install I/O cables onto the boar

d’s I/O connectors and proceed to secure the stack together or 

repeat steps 3-5 until all boards are installed using the selected mounting hardware. 

6. 

Check that all connections in your PC/104 stack are correct and secure then power up the 
system.  

7. 

Run one of the provided sample programs appropriate for your operating system that was 
installed from the CD to test and validate your installation.
