5. RS-232 Data Transmission Protocol

The SW 1000/200
the serial interface, you can modify the settings of the sound level meter, start and
stop the device, send a query about the current values of measurement parameters
or process the results. The operation using the serial interface is the same as the
operation using the keyboard.

5.1 Hardware configuration and interface settings

5.2 Transmission protocol

The RS-232 interface protocol used in SW 1000/200
sion corresponding to the following pattern:
A typical command block or response block consists of a start-of-text character, iden-
tifier (ID), attribute character, command or data, end-of-text character, block check
character, line feed character and carriage return character, as per the diagram be-
