Present computers are widely assisted by RS232 converter. In order to transmit signal into various computer conveniently, we must use RS232 converter to solve problem of BNC differences. Although there are some shortcomings of RS232 port, but many people use RS232 port. Thus RS232 converter must have a good market in the near future.
