To enable relay operation, you must use a
terminal program (for example, PuTTy) to set the GMP251/252 serial mode to relay
communication and configure the relay settings. Using serial line (Vaisala Industrial
Protocol) to configure the probe requires the following:
The default serial interface settings are
shown in the following table.
