Important: To allow communication between PLC–5s and other Data
Highway Plus nodes, you must connect your PS/2 to a PLC–5 using a
1784–CP cable. The Data Highway Plus network is connected to the
PLC–5.

The 1784–KT2 Diagnostic Program allows you to execute a set of tests to
help you make sure the 1784–KT2 is functioning properly. These tests
check various operational characteristics, such as network and host
communications, interrupts, and memory access. Test results are displayed
on your screen and recorded in the diagnostic program output file.
Important: If the 1784–KT2 does not function properly under normal
operation, follow these steps:
1. Check the configuration settings (refer to the section entitled
“Configuring the 1784–KT2”). You may have configured
the1784–KT2 at an address already in use by another adapter module.
2. If the 1784–KT2 continues to function improperly, run the 1784–KT2
Diagnostic Program to determine if there are any hardware failures. If
hardware failures are indicated, refer to the output file for resulting
error messages. (Refer to the sections entitled “Output File” and
“Error Messages” for additional information.)
3. If, after following steps 1 and 2, the 1784–KT2 continues to function
improperly, contact your local Allen-Bradley sales office.
