Digital: USB to RS485 Convertor
The KMC KMD-5576 is a USB (Universal Serial Bus) to EIA-485 (formerly RS-485) converter. It connects a computer USB port to a BACnet or KMDigital network by plugging into a KMC Tier 2 (only) controller or a NetSensor/FlexStat/STE-5×24/STE-6000 data port. It provides network access to a computer running BACstage or WinControl (but not TotalControl). USB ports have replaced the once common EIA-232 (formerly RS-232) serial ports that have been part of a legacy removal program in the computer industry. To supersede the serial port (used by the KMD-5559 CommTalk) as a network connection method, KMC Controls developed the KMD-5576 USB Communicator.
