2.2.4 Termination Resistors
Although termination resistors are not typically required, plated-through holes on the board have been left open and labeled
to allow the user to install resistors across the various inputs.

2.3 PLUG IN THE CIO-QUAD BOARD
1. After selecting and verifying the base address, and setting the configuration switches and jumpers, shut the computer off
and open the case.
2. Locate an empty expansion slot in your computer. The CIO-QUAD02 board requires a single 16-bit slot (with two
connectors). The CIO-QUAD04 requires an open slot as well as an adjacent open rear panel opening.
3. Push the board firmly down into the expansion bus connector. If it is not seated fully it may fail to work and could short
circuit the PC bus power onto a PC bus signal. This could damage the motherboard in your PC as well as the CIO-QUAD
board.
4. Secure the board in the ISA slot with the screw provided.
5. You may also wish to connect your cable, screw terminal board or other field wiring at this time.
6. Replace the cover to the computer and turn it on.
