PIO-96 User’s Manual Installation 2-7
Connecting cables to the board
NOTE Do not yet connect the cables to any external circuits. Wiring to external
circuits should be done after the procedures under “Checking your
installation.”
Each 24-bit port on the PIO-96 uses a 50-pin connector as an interface to data acquisition sig-
nals. This connector is compatible with the manufacturer’s CACC-2000 series of cables. How-
ever, please note that the standard CACC-2000 cable is only 18 inches long. Since the connector,
and up to 14 inches of the I/O cable (worst case) will be inside the computer, the standard
CACC-2000 cable may be inadequate. However, longer cables are available. Simply order a
CACC-20NN, where NN is the additional number of feet (beyond the standard 18 inches) that
you desire.
Alternatively, you can make custom cables for specific purposes. The mating connector is 3M
type 3425-6050. One is required for each 24-bit port.
Before installing the board and before connecting any external circuits, install all cables that you
intend to use, as follows:
1. Make sure that your wrist strap is on and grounded. (You should use a grounded wrist
strap. However, if you don’t have a wrist strap, touch any metallic part of the computer
cabinet with one hand before holding the board in the other hand. This will safely dis-
charge any static electricity that has built-up in your body.)
2. Connect all the CACC-2000 Series cables needed to interface to your external circuits to
connectors J1 through J4 on the board. See Figure 2-2 for locations of these connectors.
3. Continue with the next procedure, “Installing the board.”
Installing the board
This section provides general instructions for installing the PIO-96 board. For additional infor-
mation on installing peripheral boards, consult the documentation provided with your computer.
CAUTION Do not attempt to insert or remove any adapter board with the com-
puter power ON. This could cause damage to your computer.
To install the PIO-96 board, do the following:
1. Turn OFF power to the computer and all attached options.
2. Unplug the power cords of all attached options from the electrical outlets. Make a note of
where all the cables and cords are attached to the rear of the system unit and disconnect.
Failure to disconnect all external cables from the computer can result in a hazardous condi-
tion, since dangerous voltage levels may be present on externally connected cables, even
though the computer is turned OFF.
3. Remove the cover of the computer.
4. Choose an available option slot. Make sure that there is an additional empty slot to its right.
Loosen and remove the screw at the top of the blank adapter plate. Then slide the plate up
and out to remove.
5. Make sure that your wrist strap is on and grounded. (You should use a grounded wrist
strap. However, if you don’t have a wrist strap, touch any metallic part of the computer
cabinet with one hand before holding the board in the other hand. This will safely dis-
charge any static electricity that has built-up in your body.)
6. Check that you have set the desired base address.
