Communication Port J2
Communication Port J2 is configured to connect a Servlink device, such as
Watch Window, to the 723PLUS control. Watch Window is used to display and
modify tunable and configurable values in the control. Multiple values may be
viewed simultaneously. Watch Window includes the ability to shut down the
control, restart the control, and upload and download tuning parameters. The
ability is also provided to link to a control over a network via network DDE.
Port J2 connector is a 9-pin subminiature D receptacle.
Communication Port J2 can be software configured for a wide variety of serial
communications. The port can be set to standard specifications for RS-232 or
RS-422. The baud rates can be set for 110, 300, 600, 1200, 1800, 2400, 4800,
9600, 19200, or 38400. The only restriction is that if port J2 is set for a baud rate
of 19200, then port J3 cannot be 38400, and if J2 is set for a baud rate of 38400,
then port J3 cannot be 19200. The default baud rate is 19200.
In this application, Port J2 of the Starboard 723PLUS and the Port 723PLUS are
connected together and must use the multi-drop feature of Servlink when
connecting to the network.
Communication Port J3 (not used in this application)
Communication Port J3 is configured to connect a Servlink device, such as
Watch Window, to the 723PLUS control. Watch Window is used to display and
modify tunable and configurable values in the control. Multiple values may be
viewed simultaneously. Watch Window includes the ability to shut down the
control, restart the control, and upload and download tuning parameters. The
ability is also provided to link to a control over a network via network DDE.
Port J3 connector is a 9-pin subminiature D receptacle.
Communication Port J3 can be software-configured for a wide variety of serial

RS-422. The baud rates can be set for 110, 300, 600, 1200, 1800, 2400, 4800,
9600, 19200, or 38400. The only restriction is that if port J2 is set for a baud rate
of 19200, then port J3 cannot be 38400, and if J2 is set for a baud rate of 38400,
then port J3 cannot be 19200. The default baud rate is 19200.
POWER AND CPU OK LED
The POWER OK and CPU OK are green LEDs (light emitting diode). The LEDs
illuminate when the internal power supply is functioning and the CPU is operating
normally. Do Not attempt to start or run the engine when either LED is not
illuminated. The LEDs turn off if the power supply is turned off or failed and the
CPU is failed or has a watchdog error.
