    Remote Control Q: I am trying to send the commands over USB/RS232, but it does not seem to respond. Check that you are sending ASCII strings that are terminated with a CR (carriage return) and LF (linefeed) character. For RS-232 and RS-485, check that the baud rate, parity, data bits, stop bit, and flow control settings match with the settings configured on the software interface.
