Trimix Analyser Connector

One-page setup and day-to-day guide. Read the section in your language before the first use, then always compare the label with the analyser display before using the gas.

Important

The adapter copies readings and prints labels; it does not verify the gas. Confirm O2, He, MOD/END, date, and cylinder marking on the analyser before diving.

Required before live readings

Enable the analyser data output first.

On the analyser: Menu → Preferences → Send Data to USB → On. Some versions call it Data output. Without this step the adapter receives no readings. See the official Divesoft He/O2 manual, section 12 “Connecting to a computer”.

Quick-start guide

  1. First: enable data output. On the analyser select Menu → Preferences → Send Data to USB → On. Some versions call it Data output. Without this setting the adapter receives no readings. The exact menu is documented in the official Divesoft He/O2 manual, section 12.
  2. Join the setup Wi-Fi. Select TrimixAdapter-XXXX, enter password 12345678, then open http://192.168.4.1. XXXX is the end of the device ID.
  3. Setup Wi-Fi timeout. By default, setup Wi-Fi turns off after five minutes without a connected client. If it is no longer visible, restart the adapter and connect again.
  4. Pair a printer. In the Web UI, open Printer, scan for the powered-on Niimbot B1 or B1 Pro, select it and save it. Pairing uses Bluetooth; setup Wi-Fi is only needed for configuration.
  5. Time and date. Under System → Label Date/Time Source, choose analyser time if available, a set DS3231 clock, or internet time from Wi-Fi. Without a battery-backed clock, obtain network time again after power loss. With no valid time, the label says “DATE NOT SET”.
  6. Print a label. After at least five seconds of stable readings, check the analysis on the analyser and pause its data output for the configured duration (3 seconds by default). This sends one label. An optional external button also prints the current valid reading when released. Do not trigger another print while one is in progress.

Duplicate-print protection: After an automatic print, the adapter waits 30 seconds by default. Let the readings appear again before pausing for another label. You can change the wait under Web UI > Print > Label Printer.

Add Trimix Pro when you want it

Install the firmware, view live O₂ and helium readings in the browser, and print Nitrox labels without a Pro licence. Print history and CSV export are included. On Trimix labels, the helium value is replaced by “PRO” until activation. To print the actual helium percentage on Trimix labels, open Licence in the setup page, copy the 12-character Device ID and buy its Pro licence (EU billing addresses; contact us outside the EU). Your key appears after confirmed payment and arrives by email. Paste it into Activate existing key, then check a Trimix label against the analyser display. The licence works offline after activation.
