Smart Star User's Manual

> ## 1. Introduction

> Chapter 1 introduces the Smart Star embedded control system and describes the features associated with the backplane chassis and the CPU card. The Tool Kit containing the hardware essentials to begin using the Smart Star is described, and the software highlights are presented.

> The Smart Star is a modular and expandable embedded control system whose configuration of digital I/O, A/D converter, D/A converter, and relay I/O cards can be tailored to a large variety of demanding real-time control and data acquisition applications.

> The typical Smart Star system consists of a rugged backplane with a built-in voltage regulator, a CPU card, and one or more I/O cards. The CPU card plugs into a designated slot on the backplane chassis, which has additional slots available for any combination of I/O cards. A high-performance Rabbit 2000 microprocessor on the CPU card operates at 22.1 MHz to provide fast data processing.

> ### 1.1 Features

> - C-programmable to create a custom user interface

> - Flexible functionality---modular configuration allows interchanging or replacing individual I/O cards

> - Expandable--up to 168 I/O ports

> - Choice of two backplanes--with either 3 or 7 slots for I/O cards

> - Choice of CPU cards--with or without One RJ-45 Ethernet port compliant with IEEE 802.3 standard for 10Base-T Ethernet protocol

> - RS-232 and RS-485 serial ports allow networking to other Smart Star units, single-board computers, or enterprise computing centers

> - 128K SRAM and 512K flash memory, optional 512K SRAM

> - Real-time clock

> - Watchdog supervisor

> - Backup battery

> - Optional backlit 122 × 32 graphic display/keypad module

> - RabbitLink Ethernet gateway available for remote download/debug, Web serving, and e-mail

> Table 1 lists the backplanes, CPU cards, and the I/O cards that are available for the Smart Star control system. Appendix A provides detailed specifications for the Smart Star backplanes and the CPU cards.

> ### 1.2 User Connections

> Connections to the I/O cards are made via a ribbon cable connector or optional field wiring terminals that are either pluggable or have screw terminals. Three different Field Wiring Terminals (FWTs) are available. Table 2 lists the I/O cards and the Z-World part numbers for the corresponding FWTs.

> Table 2. Guide to FWT Selection
> FWT Description | I/O Cards | Z-World Part Number
> Pluggable Terminals | Screw Terminals
> FWT27 | Digital I/O Relay (SR9510) | 101-0420 | 101-0424
> FWT18 | A/D Converter D/A Converter | 101-0421 | 101-0425
> FWT18R | Relay (SR9500) | 101-0422 | 101-0426

> NOTE | Appendix A, "Field Wiring Terminals," provides further information on FWTs, including their dimensions.

> ### 1.3 Optional Add-Ons

> The LCD/keypad module is the only available optional add-on. Further details on the LCD/keypad module are provided in Appendix B.

> Visit Z-World's Web site for up-to-date information about additional add-ons and features as they become available. The Web site also has the latest revision of this user's manual.

> ### 1.4 Development and Evaluation Tools

> #### 1.4.1 Tool Kit

> The Tool Kit has the hardware essentials that you need to create and use your own Smart Star control system.

> The items in the Tool Kit and their use are as follows:

> - Smart Star (SR9000) User's Manual with schematics for the backplane chassis and the CPU cards (this document).

> - User manuals for available I/O cards.

> - Programming cable, used to connect your PC serial port to the Smart Star CPU card to write and debug C programs that run on the Smart Star control system.

> - FWT27 pluggable field wiring terminal.

> - Screwdriver.

> - DC power supply, used to power the backplane, which in turn supplies power to the CPU card and the I/O cards. The DC power supply accepts an AC input of 100 V to 240 V at up to 0.6 A, and delivers a DC output up to 1.1 A at 24 V.

> - Rabbit 2000 Processor Easy Reference poster.

> - Registration card.

> #### 1.4.2 Software

> The Smart Star control system is programmed using Z-World's Dynamic C Premier, an integrated development environment that includes an editor, a C compiler, and a debugger. Library functions and software drivers provide an easy-to-use interface for the Smart Star control system. Dynamic C Premier is sold separately.
