Important: When you connect a Data Highway Plus link to a Data
Highway II link, you must observe the following limitations:

A computer connected to a Data Highway Plus (through a 1785-KE or

1770-KF2 module) cannot access nodes on a Data Highway II through
a 1779-KP5 module.

Nodes on Data Highway II cannot access a computer connected to Data

Highway Plus.

A 1784-T50 on a Data Highway Plus link cannot program devices on

another Data Highway Plus link through the 1779-KP5.

A computer on a Data Highway II, however, can access a PLC on Data
Highway Plus through a 1779-KP5.
