[TG] [TG11] ST60+ Low Depth Alarm Setting Blocked?

[[email protected]]

Hi Tom and Derek,
Thanks for the quick reply. Sorry I didn’t provide better information regarding the layout.
I have attached a network sketch for your reference.

The depth transducer is connected directly to the ST60+ depth instrument, which is networked via ST1 to the other ST60+ displays.

The Alarm lock setting on the depth instrument is OFF.

Is it possible that a setting in the ST60+ Grasphic display could be locking out the depth alarm setting?
Maybe I need to switch off some or all of the Alarms on the ST60+ Graphic display? I’d prefer not to do this as it provides many alarm functions that are not available on the other displays.
Or is there a way to set the depth alarm on the ST60+ Grahic?

Regarding the layout, as you noted, there are two ST1 to STng converters connected to the STng backbone, one for the ST1 bus connection and one for the ST2000+ Autopilot connection.
These are on a single STng network backbone and there is only one ST1 bus connected to it.
So I (and Chuck) thought the network setup was ok - but it would be good to hear your thoughts if there might be potential data loops or other issues.

Regards
Dave
