_UMD - Model 154, M233/Serial to USB
Interface Converter


The M154, M233/Serial to Universal Serial Bus (USB) Interface uses a Virtual Serial Port Driver, making it appear to software like a standard RS232 Serial Port. This way existing POS Software can communicate with the Customer Display as though connected to a Serial Port. A unique serial number is assigned to each USB interface and and the Driver Software will assign the next available Serial Port to each device it recognises (multiple Displays can be used on one PC). The interface is designed to accept bi-directional communication with the customer display.
