B–2

Peer Master Example

The Example

This chapter provides an example of a peer-to-peer network and is designed for the

experienced user. This chapter does not provide detailed descriptions of network

concepts and communications parameters. If you’re unfamiliar with networking

concepts, or if you want to know more detailed information about DirectNET, you

may want to read Chapters 2 – 5 before setting up the example network.

A DCM peer network utilizes two DCMs, with both configured as peer stations. You

can only have two stations in this configuration. Either unit can initiate a

communications request. (The DCMs automatically compensate for the possibility

of data collisions.)

This chapter provides an example that allows you to quickly and easily set up a peer

network.
