4-8 Connecting the Interface Card

1784-6.5.27 - September 1997

Connecting to DH+ Devices

Depending on your application, you may use the PKTx card to communicate

with a single device or multiple DH+ devices via a DH+ network. This

section shows you how to connect to a classic or an enhanced PLC-5

programmable controller.

Connecting the Card to a Classic PLC-5 Programmable

Controller

To connect the 1784-PKTX or -PKTXD card to a classic PLC-5

programmable controller, follow these steps:

1. Turn off power to the computer.

Important: If you disconnect the ac power from the computer, you lose

the chassis ground. Electrostatic damage (ESD) protection is

lost.

ATTENTION: Not all software and hardware supports

115.2K bit/s or 230.4K bit/s for DH+ communications.

Make sure your software and hardware supports the baud

rate your select.
