Serial COM Port Emulator

When connecting a PC and a RA800 audiometer utilizing their USB ports the Adapter provides virtual “PC COM Ports” allowing existing software products, previously designed to communicate with Tremetrics audiometers, to retrieve data from the RA800 audiometers, possibly negating the need for software modification.
