IA250 is a universal isolated interface adapter, designed to support interface connection between COMECO devices and PC or other USB devices. Its electronics is enclosed in a small-sized plastic box with IP54 front protection and equipped with USB-B and RJ25 interface connectors. Powered by the USB interface line, this plug-and-play device does not need any additional power supply. Two IA250 variants are available:
– a variant for configuration and data collecting from a network of various COMECO control devices with RS485 interface and net addresses;
– a variant for configuring COMECO transmitters via quasi-RS232 interface. IA250 is applicable to the “PolyMonitor” data-acquisition software and the transmitter-configuration program “TraCon”,
and may also be used with customer-developed PC software based on the free communication protocols of the COMECO devices.
