Technical description

The senddata command sends the SEND DATA message to MD30 and parses the response.

The data interval is given as a parameter in milliseconds. If the parameter value is:

  • 0 = only 1 data set is sent as a response

  • 25–5000 = message sending starts with the defined data interval

Only numeric values are counted as parameters.

Example 1

Data request with data interval 0.

Only one data set is sent as a response.

Example 2

Data request with data interval 1000.

The unit starts to send data with the defined data interval. You can stop the data sending with command s.

Example 3

Data request with data interval 10.

The data interval is not valid, which causes an invalid data error (error code = 4).

/> senddata 10
