From its first introduction in the early 1960’s, the RS-232 protocol originally had been used for data signal transfer to such instruments as teletypewriters which were Data Terminals for binary communication. Now, we have integrated newer USB 3.0 standards technology with older but still active RS-232 protocols. GearMo is rapidly moving ahead with utilization of USB to RS-232 adapters that require no configuration by the consumer using built-in plug and play features. This adapter is 12 inches long, very portable yet uses the Best FTDI Chip to make any RS232 connection Easy!
