3.1.2 Installing the PC Link Module in the Personal
Computer
Use the following procedure to install the module:
Step 1.
Turn your computer off. Disconnect the power cord.
Step 2. Remove the cover on your computer. Consult the user's
manual for your computer on installing addĆin boards.
Step 3. Find a free expansion slot in your computer. If you are not
sure which slot to use, consult the user's manual for your
computer. Use a screwdriver to remove the slot cover
screw and the slot cover from your computer.
Step 4. Take the module out of its shipping container. Take it out of
the antiĆstatic bag, being careful not to touch the
connectors on the bottom of the board or any of the
surface of the board.
Step 5. Set the DIP switches for the appropriate port address. See
section 3.1.1 and Table 3.1 for more information.
Step 6. Insert the module into your computer. Make sure the
goldĆstriped bottom edge of the board sits firmly in the
expansion slot groove, and that the bracket of the board is
in the groove which previously held the expansion slot
cover. Secure the board with the slot cover screw.
Step 7. Replace the cover on your computer.
3.1.3 Connecting the PC Link Module to a DCS/AutoMax
Network or Remote I/O Network
When connecting to the AutoMax Network or a Remote I/O network,
the PC Link module should be wired with the same cabling and
termination as any other drop. A BNC Tee Adaptor (M/N 45C70)
should be used to connect the network cable to one of the BNC
connectors on the back of the PC Link module. Note that the second
BNC connector on the module will not be used. The network is then
complete through the tee, and the module can be connected or
disconnected without disturbing the rest of the network. Stop any
application tasks that are running before disconnecting the PC Link
drop.
The module does not have an onboard terminator. If it is at the end of
the coaxial cable system, it must be terminated with a 75Ćohm
terminating load (M/N 45C71). Refer to the Network Communications
Module instruction manual (J2Ć3001) or the Remote I/O
Communications instruction manual (JĆ3606) for a detailed
description of how to connect a drop to the network.
