Interfacing Notes

For the interfacing from RS232 to the transmitter a level shifter is needed (for details see transmitter manual).

The cable running from the shifter to the COM port can be a flat cable or a cable without pin swapping.

Because the transmitter will wait a few seconds before the data is ready to be retrieved the update rate for the Paroscientific SDI-12 transmitter has to be set to 10 seconds minimum to ensure that all the data is recorded in the database.

For the slot number of the observations see below:
