Appendix A – Dual Station Operation
Multiple DS41 instruments can be installed on a single vessel. These instruments can be connected together and configured to operate in a dual station configuration. One instrument is designated as a master and all other instruments, connected to it, are configured as slaves. The master device is connected to the depth transducer and determines the water depth. This information is then displayed on all slave devices connected to it. Slave devices do not have transducers connected to them.
The slave devices can be configured to operate as fully functional NMEA repeaters where they display water depth, as displayed on the master device, and share common alarm settings and keel offset values. In this mode the common alarm settings can be changed or activated/ deactivated from either the master or slave devices.
Alternatively, the slaves can be configured to operate as independent slaves. In this mode the slaves display the water depth received from the master, but have independent alarm settings and keel offset values.
Note:
The instrument designated as the master device is the only instrument connected to the depth transducer.
