MiniCom (OP6800) User's Manual

> ## 1. Introduction

> The OP6800 intelligent terminal interface is a small, high-performance, C-programmable terminal interface that offers built-in I/O and Ethernet connectivity. A Rabbit 2000 microprocessor operating at 22.1 MHz provides fast data processing.

> ### 1.1 Description

> The OP6800 intelligent terminal interface incorporates the powerful Rabbit 2000 microprocessor, flash memory, static RAM, digital I/O ports, RS-232/RS-485 serial ports, and a 10Base-T Ethernet port.

> ### 1.2 Features

> - 122 × 32 graphic display.
> - 7-key keypad.
> - 7 LEDs.
> - 24 digital I/O: 13 filtered digital inputs, and 11 sinking high-current outputs (7 outputs with LED indicators, and 4 high-current digital outputs with transient protection to drive inductive loads).
> - Rabbit 2000TM microprocessor operating at 22.1 MHz.
> - 128K static RAM and 256K flash memory standard, may be increased to 512K SRAM and 512K flash memory.
> - One RJ-45 Ethernet port compliant with IEEE 802.3 standard for 10Base-T Ethernet protocol (OP6800 only).
> - Four serial ports (2 RS-232 or 1 RS-232 with RTS/CTS, 1 RS-485, and 1 CMOS-compatible programming port).
> - Battery-backable real-time clock, connection point for external battery included.
> - Watchdog.
> - Reset generator.
> - Meets NEMA 4 watertightness specifications when front-panel mounted.
> - Remote program downloading and debugging capability via RabbitLink.

> Two OP6800 models are available. Their standard features are summarized in Table 1.

> ### 1.3 Development and Evaluation Tools

> #### 1.3.1 Tool Kit

> A Tool Kit contains the hardware essentials you will need to use your OP6800. The items in the Tool Kit and their use are as follows.

> - OP6800 User's Manual with schematics (this document).
> - Programming cable, used to connect your PC serial port to the OP6800.
> - 12 V AC adapter, used to power the OP6800. An AC adapter is supplied with tool kits sold in the North American market. If you are using your own power supply, it must provide 9 to 36 V DC.
> - Demonstration Board with prototyping area, pushbutton switches, and LEDs. The Demonstration Board can be hooked up to the OP6800 to demonstrate the I/O, and the prototyping area can be used for custom circuits.
> - Ribbon cable to connect Demonstration Board to OP6800.
> - Screwdriver.
> - Rabbit 2000 Processor Easy Reference poster.
> - Registration card.

> #### 1.3.2 Software

> The OP6800 is programmed using version 7.06 or later of Z-World's Dynamic C Premier, an integrated development environment that includes an editor, a C compiler, and a debugger. Library functions provide an easy-to-use interface for the OP6800. Software drivers for the display and keypad, TCP/IP, I/O, and serial communication are included with Dynamic C Premier.
