OP6800 MiniCom 
Models OP6800, OP6810
Description
The MiniCom is a low-cost, C-programmable operator interface and single-board computer that offers Ethernet connectivity, plenty of industrialized I/O, a graphic LCD, and keypad. The MiniCom's compact 4.5" x 3.6" (112 mm x 91 mm) form factor makes it ideal for use in designs and areas with size constraints. Available in both Ethernet-enabled and non-Ethernet versions, the MiniCom provides comprehensive integrated control, display, and networking capabilities via Internet/Ethernet or serial communications.
Features
- 122 x 32 graphic display/keypad
- 24 industrialized digital I/O
- Optional 10Base-T Ethernet
- Quick-start menu program
- Meets NEMA 4 water resistance
- 4 serial ports
Both the Ethernet-enabled OP6800 and the non-Ethernet OP6810 feature 24 rugged digital I/O, an international-character 122 x 32 pixel LCD, user-relegendable keypad with 7-key / 7-LED interface, 4 serial ports, Rabbit® 2000 processor at 22.1 MHz, and 256K Flash/128K SRAM (standard). The OP6800's Ethernet capabilities facilitate remote diagnostics, communication, and control, including sending and receiving E-mails and alerts. When front-panel mounted, both MiniCom models meet NEMA 4 water-resistance compliance standards, making them suitable for use in harsh environments.
The MiniCom's I/O and communication signals connect via ribbon cable headers. Input power requirements (10-36 V DC) allow the MiniCom to be used in a wide variety of fixed and mobile applications. Provision is made for external battery backup to maintain real-time clock values and data stored in SRAM.
The MiniCom's digital I/O includes 13 filtered inputs and 11 sinking outputs—7 standard outputs also have indicator LEDs, and 4 heavy-duty outputs offer transient protection to drive inductive loads. The inputs are designed to interface with logic levels or a switch closure to ground. The inputs support a range of 9-36 V DC, and all outputs are rated at 200mA, 40 V DC.
The 122 x 32 pixel graphic display supports English and foreign language fonts, as well as simple graphic and bitmap images. A font converter program is supplied, and different fonts, languages, and sizes can be used simultaneously. The MiniCom also makes an ideal operator interface for other Rabbit single-board computers.
Programming the MiniCom
Programs are developed using Rabbit's industry-proven Dynamic C® software development system. An extensive library of drivers and sample programs is provided, along with royalty-free TCP/IP stack with source. All MiniCom models can be programmed and debugged over Ethernet/Internet using appropriate accessory hardware.
A quick-start menu system utilizes a scroll-up and down highlight-bar for menu option selection and is designed to easily Add/Delete options to the menu structure. The quick-start menu also provides page-up and page-down control for large menus, as well as sub-menus nesting capability, designed to pop-up to the original calling menu option.
