1.2 Serial Line Configuration
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:
• Vaisala USB service cable (order code 242659)
• Computer with:
• Windows operating system
• Terminal application (for example PuTTy, available from
www.vaisala.com/
software )
• Free USB port
• Driver for Vaisala USB service cable installed (available on the cable installation
media and at www.vaisala.com/software )
The default serial interface settings are shown in the following table.
