Technical Guide

Explicit Addressing & Domain Table Setup

To use explicit addressing, the client needs to change the factory settings

contained in the PT-Link II LON’s conﬁ guration ﬁ le (conﬁ g.csv). The

following are the steps to change the conﬁ guration ﬁ le from implicit to

explicit addressing:

1.) Upload and open the conﬁ g.csv ﬁ le.

2.) Locate the “Connections” section.

3.) Locate the “Lonworks_Server” column and change the

value from “Implicit” shown in Figure 17 to “Explicit”

shown in Figure 18. You should also change the “Lon

works _Input” and “Lonworks_Outputs” from Update to

Polled.

In addition, the PT-Link II LON must have its domain, subnet, and node

IDs set. This feature is enabled in the conﬁ guration ﬁ le by ﬁ lling out

the Title and System_Address ﬁ elds of the PT-Link II LON parameters

as follows:

//==================================================

// Common Information

Bridge

System_Address ,Title

23 ,”:D48:S01:Wattmaster Explicit Lon v1.00d”

Setting

The Title ﬁ eld must start with “:D”, followed by the domain_id in

hexadecimal notation, followed by “:S”, followed by the subnet_id in

hexadecimal notation, and enclosed by “:”. The domain length is auto-

matically determined by the number of digits in the [domain_id] ﬁ eld.

With 2 hexadecimal digits constituting 1 byte, “:D123456:”, for example,

would have a length of 3.

Once the domain table has been set, the “:Dxx:Sxx:” part of the Title

ﬁ eld will be removed.

Now the Title ﬁ eld will be left with [Title continued…] which may be

the Node self documentation string or any title.
