Select the same baud rate that has been set on the CEL-450/490. It is recommended that the highest setting (115200) be selected on both the instrument and dB23 in order to give the fastest communication. (NOTE: When communicating with sound level meters via a GSM modem, a Baud rate of 9600 must be used.
