The OP7200 intelligent operator interface is a small, high performance, C-programmable single board computer and display unit that offers built-in I/O, Ethernet connectivity, and an optional touchscreen. A Rabbit 2000 microprocessor operating at 22.1 MHz provides fast data processing.

The compact OP7200 eDisplay is an intelligent operator interface ideal for data acquisition and stand-alone systems such as factory floor controls.

The OP7200 is designed for panel mounting and is NEMA-4 compatible. The OP7200 incorporates the powerful Rabbit 2000 microprocessor, flash memory, static RAM, industrialized digital I/O ports, RS-232/RS-485 serial ports, a 10Base-T Ethernet port, and eight optional A/D converter inputs and touchscreen.

RabbitNet

The OP7200 has one RabbitNet port, which can support one peripheral card. Distances between a master processor unit and peripheral cards can be up to 10 m or 33 ft. The following low-cost peripheral cards are currently available.

• Digital I/O
• A/D converter
• D/A converter
• Display/Keypad interface
• Relay card

RabbitNet expansion ports enable you to design a modular and expandable embedded control system for real-time control, display, and data-acquisition applications.

A typical RabbitNet system consists of a master single-board computer (SBC) and one or more peripheral cards. A Rabbit microprocessor on the master provides fast data processing, and the master SBC also provides the DCIN and +5 V power for the peripheral cards.

Programming the OP7200

Programs are developed for the OP7200 using Rabbit’s industry-proven Dynamic C® software development system. Dynamic C® offers an extensive library of drivers and demo programs, along with royalty-free TCP/IP stack with source. You can program and debug both OP7200 models over Ethernet/Internet using the appropriate accessory hardware. Demo programs include pop-up menuing, onscreen keypads, data transmission/reception over TCP/IP and serial connections, analog volt meter display, and many more.
