The D5000 Four Channel Sensor to Computer Modules are a family of complete solutions designed for data acquisition systems based on personal computers and other processor-based equipment with standard serial I/O ports. The modules convert four analog input signals to engineering units and transmit in ASCII format to any host with standard RS-485 or RS-232C ports. These modules can measure temperature, voltage and current. The modules provide direct connection to a wide variety of sensors and perform all signal conditioning, scaling, linearization and conversion to engineering units.The modules contain no pots or switches to be set. Features such as address, baud rate, parity, echo, etc. are selectable using simple commands over the communications port-without requiring access to the module. The selections are stored in nonvolatile EEPROM which maintains data even after power is removed. The key to the D5000 series is that the modules are easy to use. You do not need engineering experience in complicated data acquisition hardware. With the D5000 series modules, anyone familiar with a personal computer can construct a data acquisition system. This modular approach to data acquisition is very flexible, easy to use and cost effective. The modules can be mixed and matched to fit your application. They can be placed remote from the host and from each other. You can string up to 30 modules on one set of wires by using RS-485 with repeaters.
