Remote Terminal Unit
The M2000 Wireless Communicator is a web-to-wireless remote monitor, control, and communication device. An internal cellular modem passes data between remote modbus devices and a secure web server. RS232 and RS485 serial ports are used to communicate with a large variety of Intelligent Electronic Devices (IEDs) such as programmable controllers and measuring instruments using the standard modbus protocol.
As an Intelligent Modbus Master, the M2000 polls and reads data from specified addresses in modbus slave devices; as an Intelligent Modbus Slave, the M2000 is configured to accept commands and data from a Modbus master device. In both the master and slave modes, the M2000 will compare the data to customer-defined setpoints and automatically report to the web server when a specified condition exists or when one of the limits is exceeded; as a Web-to-Wireless Slave Modem, the M2000 can be used as a completely flexible wireless Modbus-to-cellular-to-web communication system, much like a simple modem. The modem mode does not analyze or format the data it receives; it simply transmits it to and from the web server.
Uses Cellular Control Channel Communication; No local cellular account required; 0.6 or 1.2 Watt transmit power at 824-849 MHz. Transmit power is automatically adjusted; Receive frequency: 869-894 MHz ; Compatible with the North American AMPS analog cellular system; The standard M2000 operates from 8-30 VDC (1.6 Amp peak current draw during transmit); extruded aluminum enclosure for indoor applications (6?x3?x2? high) makes it suitable for a wide variety of general monitoring applications; external NEMA 4 enclosure and integrated 120 VAC power supply also available
