eDisplay (OP7200)

User’s Manual 1
1. INTRODUCTION
The OP7200 intelligent operator interface is a small, high-
performance, C-programmable data acquisition 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 OP7200 is designed for panel mounting and is NEMA-4
compatible. The OP7200 incorporates the powerful Rabbit 2000
microprocessor, flash memory, static RAM, industrialized digi-
tal I/O ports, RS-232/RS-485 serial ports, a 10Base-T Ethernet
port, and eight optional A/D converter inputs and touchscreen.
1.1 Features
•Small size: 4.4" ×5.7" ×1.7" (112 mm ×144 mm ×43 mm).
•¼VGA LCM display (320 ×240 pixels) with white LED backlight.
•Software-controlled LCD contrast and backlight on/off.
•9-key keypad.
•LCD controller and SRAM compatible with OP7100.
•4 status LEDs.
•24 digital I/O: 16 filtered digital inputs with an input range of ±36 V DC and a switch-
ing point of 2.4 V, and 8 sourcing/sinking/tristate high-current outputs (250/350/0 mA).
•Rabbit 2000™microprocessor operating at 22.1 MHz.
•Audible alarm buzzer.
•128K static RAM and 256K flash memory standard.
•One RJ-45 Ethernet port compliant with IEEE 802.3 standard for 10Base-T Ethernet
protocol.
•Four serial ports (2 RS-232 or 1 RS-232 with RTS/CTS, 1 RS-485, and 1 CMOS-com-
patible programming port).

2eDisplay (OP7200)
•Onboard backup battery for real-time clock and SRAM, connection point for external
battery included.
•Watchdog.
•External reset input.
•Meets NEMA 4 watertightness specifications when front-panel mounted.
•Optional 8-channel 12-bit A/D converter.
•Optional 4096 ×4096 analog touchscreen.
Two OP7200 models are available. Their standard features are summarized in Table 1.
Appendix A provides detailed specifications.

1.2 Development and Evaluation Tools
1.2.1 Tool Kit
A Tool Kit contains the hardware essentials you will need to use your OP7200. The items
in the Tool Kit and their use are as follows.
•OP7200 User’s Manual with schematics (this document).
•Dynamic C SE CD-ROM, with complete product documentation on disk.
•Programming cable, used to connect your PC serial port to the OP7200.
•12 V AC adapter, used to power the OP7200
. An AC adapter is supplied with tool kits
sold in the North American market. If you are using your own power supply, it must pro-
vide 9 to 40 V DC
or 24 V AC.
•Demonstration Board with pushbutton switches and LEDs. The Demonstration Board
can be hooked up to the OP7200 to demonstrate the I/O.
•Wire assembly to connect Demonstration Board to OP7200.
•Screwdriver.
•Rabbit 2000 Processor Easy Reference poster.
•Registration card.
