Page 11: Introduction
This document aids in the writing of the interface program for your host computer. At the initial installation, configure the 4985 Network Controller for the network it should operate. There are three banks of dip switches for functional configuration of the controller. Each bank contains eight switches.
Page 12: About The Controller
This connection provides a gateway for data to pass between the HHCs and your host using logical channels and record types. This guide primarily covers the asynchronous interface which is 4980-compatible. The primary difference between the 4980 and 4985 is 4985 Network Controller Programmer’s Guide...
Page 13 SECTION 1 Introduction " the 4985 Controller has only two ports and lacks a display, keypad, and disk drive. Since one port is dedicated to the host interface, there is only one port remaining for communicating with HHCs. The different record types, sent back and forth between the controller and the host, help tailor the communications session to meet that spe- cific session’s needs.

Page 20: 4985 Configuration Switches
Getting Started " 4985 Configuration Switches Three 8-position DIP switches allows a user to customize the 4985 for their particular system application. Switches “1” through “5” of DIP bank #2 apply only to ADCCP host applications. DIP bank #3 config- ures the controllers identification number for a large system.
Page 21: Figure 2-7 Typical Host-To-4985 Setup
The host communicates with the 4985 Controller using the NORAND asynchronous proprietary protocol. The multidock connects to the LAN port on the 4985 Controller and the host to the HOST port. The primary controller use is to facilitate the host-to-HHC communica- tion session.
Page 22: Figure 2-8 1-Byte Identifier
It consists of four parts. Device Channel A device channel is zero as the 4985 is directly connected, the ASYNC interface is used, and an HHC channel will be “1”, “4”, or “7.” The de- vice channel identifies which controller the HHC channel belongs to.
