Terminal Program Settings
The instructions below describe how to connect to PTB330 using the
PuTTY terminal application for Windows. Perform the necessary
cabling and configuration of the transmitter before following the
instructions.
PuTTY is available for download at www.vaisala.com .
NOTE PuTTY cannot be used to access the transmitter through the User Port if
PTB330 is configured to use the MODBUS protocol. However, you can
always use PuTTY to access PTB330 through the Service Port.
