1. Introduction

This document describes the control program software for the Sierra Video Systems SmartLinx Bus Adapter,

a.k.a. SmartLinx Host Adapter.

Additional documents should be referred to for complete information:

• Circuit schematics for the control processor board.

• Bus Adapter Processor Board C Runtime Support Code document.

• SmartLinx protocol document.

• 68302 Processor C Function Library document.

• 68000 Processor Library document.

• General-Pur pose C Function Library document.

• Motorola 68302 processor handbook.

• Sierra Systems C Compiler Manual

2. DIP and Rotary Switch Settings

This section describes DIP and Rotary switch settings.

2.1 DIP Switch S6

1 2 3 4 5 6 7

Sw 1: Fast Acquire Mode: 0 = 15 seconds to poll all non-responding devices 1 = 5 seconds to poll all non-responding devices

Sw 2: Disconnect Tolerance: 0 = Disconnect after one failure to respond to a poll 1 = Disconnect after

Sw 3: Flow Control: 0 = Hardware flow control (CTS/RTS)

Sw 4: Poller Enable: 0 = Bus adapter not enabled for polling 1 = Bus adapter is enabled for polling

Sw 65: Host Port B Speed: 00 = 9600 bps; 01 = 38,400 bps; 10 = 115,200 bps; 11 = 230,400 bps

Sw 87: Host Port A Speed: 00 = 9600 bps; 01 = 38,400 bps; 10 = 115,200 bps; 11 = 230,400 bps

Off On (0) (1)
