INTRODUCTION
It is possible to configure the ‘Aux’ port on the SeaKing Sonar for input of RS232 / RS485 serial
data from an MDL (or compatible) Gyro.
It may be possible to power the Gyro from the Sonar Aux Port but first check that the Power ranges
are the same. The 24VDC power that is applied to the Sonar ‘Main’ port is linked directly through to
the Aux port.
If the Gyro power requirements are 6 - 16VDC then DO NOT power directly from the Sonar AUX
Port as this may damage the Gyro.
Caution
!
Note:
It is recommended, whenever possible, that RS485 be used for the Gyro to Sonar Aux Port
telemetry link. Using RS485 (instead of RS232) avoids breaking the power isolation in the SeaKing
head.
