The service port of the data logger provides a local interface for performing service actions that cannot be done over the air, such as updating the device firmware. The service actions are based on file transfer using Media Transfer Protocol (MTP), so no special software is needed. The service port connector is a standard micro-USB connector.

The service port can be used to supply operating power to the data logger. Use a power supply that fulfills the requirements listed in Table 8.

Batteries with a sufficient voltage must always be in place inside the data logger when the data logger is started, even when supplying external power through the service port.

CAUTION When using an external power supply, the main batteries will be drained very slowly. As alkaline batteries may leak when left in place for a long time, always use compatible 1.5 V lithium batteries instead of alkaline batteries when using an external power supply.
