Description

The Model 2800 is a LonWorks based product that combines many different interfaces into a single very compact unit.  It has two high-speed serial ports, four analog inputs, real-time clock, I2C Expansion Bus, and over 500K of serial flash memory.   It is designed to allow system developers to quickly create LonWorks serial and analog gateways to existing systems.  An extensive function library is supplied to help the development and integration process.  It is available in NEMA 4X and DIN Rail mount enclosures.

Key Features

bulletVery compact design available in DIN Rail and NEMA 4X enclosures.
bulletNeuron 3150 at 10 MHz and FTT-10A network interface.
bulletSwitching power supply with wide input voltage range of 8 to 32 VDC.  Minimizes heat and power consumed under a variety of input voltage conditions.  Helpful in battery backed systems.
bullet32K Non-volatile memory with unlimited writes.  Use as RAM or EEPROM and   there is no battery.
bulletStandard 28-Pin dip memory socket accommodate lower cost flash or OTP ROM for mass production.
bulletReal-time clock with capacitor backup.  Maintains clock for 15-30 days without power.
bulletTwo memory mapped serial ports with a 128 byte transmit and receive buffers reduce firmware overhead. 
bulletEach serial port can be configured for RS232, RS485/RS422 Full Duplex, RS485 Half Duplex, or TTL.  Port configuration is under software control and is jumper-less.
bulletFull RS232 handshake signals (RTS, CTS, DTR, DSR, DCD) on each serial port. 
bulletTransmit and Receive Status LEDs for each of the serial ports.
bulletAll serial port communication lines have 10KV ESD protection and are protected to +/- 25 volts.
bulletHigh quality removable terminal blocks on all connections.
bulletExpansion connector allows additional I/O to be added via I2C bus interface.
bulletSupport for two 0-23 mA analog inputs.  Supports self and loop powered devices.  The current inputs are reverse voltage protected and current limited to avoid damage under faulty wiring conditions.
bulletSupport for two analog 0-5 Volts inputs.  The two voltage inputs can be read individually or differentially.  Low noise, 10 PPM, 5.0 volts analog reference is available to drive low current bridge sensors.
bulletThe Analog to Digital converter has 16-bit resolution and a firmware selectable gain of 1, 2, 4 or 8.
bullet500+ K bytes of serial flash for data logging.
bulletTwo status LEDs provide quick visual indication of runtime status conditions.
bulletExtensive development library and demo application available at no charge to help speed up integration and custom application development.
