Options for the COM port, baud rate and Stop bits can now be

configured.

4. Select the COM port to which the CEL-450/490 is connected.

5. 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.)

No communication will be possible if the instrument and software

have different baud rates selected (See the CEL-450/490 manual

for instructions on setting the instrument baud rate).

6. Select either 1 or 2 stop bits.

When communicating with a PC it makes no difference which

option is selected.

7. Select OK to accept the settings and close the dialog.

The settings will be stored and retained for further dB23 sessions.

8. Switch the CEL-450/490 ON.

The sound level meter recognises that it is connected to a PC

and indicates this during the start up sequence, before

continuing on to a Calibration screen.

Communication with the sound level meter can now occur at any

time. However, if the instrument is carrying out a run, the

current measurement cannot be downloaded, although all other

stored runs can be accessed.

Interface status: RS 232 connected
