Where to Go
Connecting to Remote I/O Devices
Depending upon your application, you can use the PKTx card to
communicate with a single device or to multiple devices via a remote I/O
link.
To connect the PKTx card to remote I/O, use Allen-Bradley 1770-CD or
approved cable to construct a custom cable. See publication ICCG-2.2 for
a list of approved cables.
Important: For proper operation, terminate both ends of a remote I/O link
by using external resistors. Use either an 82Ω or 150Ω
terminator (see Table 4.D).
