Multi-way connector
Power is supplied to the sound level meter via an 18-pin connector running from the Interface Box. The socket
for this is behind the protective rubber cover at the bottom of the sound level meter.
Plug the connector gently into the socket. There is an arrow embossed on the upper side of the multiway
connector to ensure that it is aligned correctly.
USB input
The USB connection on the bottom of the Optimus sound level meter can be used to download measurement
information to the NoiseTools software.
To download data directly via the USB connection, connect a standard USB cable to the socket on bottom of
the sound level meter and connect the other end to a PC running the NoiseTools software.
When the optimus is connected via USB to a PC, modem functionality is disabled and the USB
connection will take priority.
External connectors
The environmental noise measurement kits have two input connectors which are located on the outside of the
case as shown below:
