Chapter 3
Data Communications Setup
Introduction
Overview
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 Communications System (ACS) network.
The DNH consists of two identical hubs (‘A’ Half and ‘B’ Half) in one
enclosure. 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.
