Service Port (RS-232) Communications

The Service Port utilizes RS-232 communications and supports Woodward's
Servlink protocol for monitoring and tuning of software variables. The Service
Port is used for calibration, troubleshooting, and alarm/shutdown monitoring.
Additional functions available through this port include tuning, configuration, and
monitoring of the driver and actuator. It also supports configuration upload (send)
and download (receive) as well as the capability to install a new application
program in flash. If CAN is not used, the Service Port is the only means of
identifying/determining specific alarm and shutdown causes.
The Service Tool software resides on a PC (personal computer) and
communicates to the driver through the Service Port. The unit is typically in the
Normal (Running) mode. However, there are three additional modes available to
the customer for setup and monitoring: Configuration, Service, and User
Calibration. The Service Tool provided is Woodward Watch Window using the
Servlink DDE server. The service tool programs have password protection to
prevent inadvertent changes.
