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.

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
