2.11.2 CONFIGURATION PORT
NOTE: For further details of module configuration, refer to DSE Publication: 057-283
DSEA109 Configuration Suite PC Software Manual.
Caution: Do not disconnect the USB from DSE815 whilst it is connected to the AVR. Doing
so results in loss of voltage control and potential damage to the generator.
WARNING! As the AVR is isolated from ground it is possible that the configuration is live
during operation.
In conjunction with the DSE815 Configuration Interface, the Configuration Port is provided to give a
simple means of connection between a PC and the controller.
Using the DSE Configuration Suite Software, the operator is then able to monitor the device and
perform reset operations.
Additionally, the various operating parameters are available to be viewed or changed.
To connect a module to a PC by USB, the following items are required:
•DSEA109
•DSE815 Configuration Interface
•DSE Configuration Suite PC Software (available from www.deepseaelectronics.com).

Page 20 of 60
4 SETUP PROCEDURE
CAUTION: To protect the alternator, ‘De-excite’ the alternator as described by the
alternator manufacturer before commisioning the engine governor. Only re-enable the
alternator after successful governor comissioning.
WARNING!: LIVE PARTS exist within the AVR. When powered avoid contact with
components and terminals. Terminals remain live for up to 70 seconds after shutdown. Do not
touch during this time. Only qualified personnel, having full understanding of the application
must install the product.
NOTE: A suitably located and easily reached switch or circuit breaker must be fitted and
clearly marked as the disconnecting device for the AVR.
CAUTION: Do not disconnect the USB from DSE815 whilst it is connected to the AVR.
Doing so results in loss of voltage control and potential damage to the generator.
NOTE: For further details of module configuration, refer to DSE Publication: 057-271
DSEA109 Configuration Suite PC Software Manual.
The engine must be commissioned as far as possible before this procedure is carried out, in particular
the governor must be setup to produce stable speed control at 1500 RPM / 1800 RPM.
Use DSE Configuration Suite PC Software to upload the factory default configuration to the AVR if
required.
