This chapter provides maintenance personnel instructions for making the operational settings for the Advance DataNET Hub (DNH). Once these operational settings are made the DNH will function as a communication router on an Advance Communication System (ACS) network.

The DNH consists of two identical hubs (‘A’ Half and ‘B’ Half) in one en- closure. Each hub half contains a communication board and RS-232 Configuration port. Both communication boards must be configured in order for both hubs to communicate on the ACS.

Review Chapter 4, Command Line Summary. Chapter 4 provides defini- tions for all of the commands you will be using in this chapter.
