There are two ways to communicate to a remote Data Highway Plus link:
Using a Data Highway II Link Number
Using a Data Highway Plus Link Number
The following sections show these two methods.
Using a Data Highway II Link Number
This method limits you to addressing a total of 15 nodes (02 through
20 octal) on a Data Highway Plus link, but it is also easier to implement.
Important: The address of the initiating Data Highway Plus node must
be between 02 and 20 (octal) so that the reply message can be returned.

and 20 (octal) so that the reply message can be returned.
Figure 5.4 shows an example configuration using a remote Data Highway
Plus link.
