Lars Thrane LT-3100S GMDSS · 95-102251 Rev1.09 · 2025-04. Only LT-3100S and LT-4200S in the cited editions; do not apply their procedures to non-S systems.
How it connects
Dashboard separates System Units, Telephony, Data and BAM. Compare connected core units with the actual installation; an absent optional LT-3150S, LT-3140S or LT-3160S is not automatically a fault. Record Data status and RX/TX separately from SIP-line status. Messages > MSI is informational: browser viewing does not prove a message was read on the LT-3110S display. An unread-MSI alert still requires the operator’s attention. Use existing Dashboard records to distinguish installed-unit, network and alert states. The diagnostic archive is encrypted for the manufacturer; this site cannot decode it. Non-emergency recording only. Do not trigger Distress or SSAS, start tests, reset, update software or repeat commissioning. In real danger follow the exact official emergency instructions.
