How to import dives from a Scubapro Meridian
The Scubapro Meridian transfers over serial cable only. iOS does not expose that kind of connection to apps, so the dives come across once through a Mac or PC, then live on your phone forever.
Transfer the dives off the Scubapro Meridian
- Install the driver for the cable
The serial cable is a USB-to-serial adapter, and its chipset needs a driver before any software can see the Scubapro Meridian. Install the CP210x (Silicon Labs) for the cradle models. The Windows cradle package ships CP210xVCPInstaller_x64/x86.exe and slabvcp.inf, the macOS package ships SiLabsUSBDriverDisk.dmg. Bluetooth models need no driver at all; the pre-2015 Galileo/Aladin generation uses an IrDA infrared adapter (IR778), not a USB-serial chip. driver, then reboot. Skip this and the desktop app will report no device on a cable that is working perfectly.

These cables are USB-to-serial. Without the CP210x driver the port never appears, and the software reports no device. - Connect the Scubapro Meridian to a Mac or PC
Use the serial cable made for the Scubapro Meridian, not a generic charging cable: the data pins differ. Check the o-ring is seated, line the connector up with the notch on the case, and turn it to lock. An iPhone or iPad cannot open this kind of connection at all, so this step has to happen on a computer.
The o-ring must be in place, the nub lines up with the notch, then the head turns a quarter turn to lock. This cable is CP210x (Silicon Labs) for the cradle models. The Windows cradle package ships CP210xVCPInstaller_x64/x86.exe and slabvcp.inf, the macOS package ships SiLabsUSBDriverDisk.dmg. Bluetooth models need no driver at all; the pre-2015 Galileo/Aladin generation uses an IrDA infrared adapter (IR778), not a USB-serial chip.. - Put the computer into PC mode
Switch the Scubapro Meridian into its PC or upload mode before you launch the software, not after. Most desktop apps only look for the unit at startup, so a computer that wakes up late is a computer the software never finds.
Most units only hold this mode for a minute or two, so do it last, right before you connect. - Download the dives with desktop software
Read the computer with LogTRAK or Subsurface. Subsurface is free, open source, runs on macOS, Windows and Linux, and supports this model.
- Export the dives as UDDF
Export the whole logbook to a UDDF file. UDDF is the open dive-log exchange format and keeps the full depth profile, not just the summary numbers.
Export the whole logbook, not the visible page. UDDF keeps the sample-by-sample depth profile, which a summary CSV does not. - Import the file into SeaLog
Get the file to your phone. AirDrop, iCloud Drive or email all work, anything that lands it in the iOS Files app. Then in SeaLog tap the plus button, Import dives, UDDF file, and pick it. Every dive arrives with its profile, and duplicates are skipped.
A dive log app for the Meridian
Once the dives are in, SeaLog treats them like its own: a scrubbable depth profile, the site pinned on a map, water temperature, gas and tank, buddies, and the photos from your camera roll matched to the minutes you were underwater. Tag the animals you saw and they go into your species life list. It works offline on the boat and syncs when you are back, and your whole logbook exports to UDDF, CSV or PDF whenever you ask, so nothing is locked in here either.
Scubapro’s own software and drivers
Alive and actively maintained on mobile (LogTRAK 2.0 was last updated 1 July 2026, v1.13.1) but frozen on desktop: the legacy Windows/Mac LogTRAK is still downloadable and still notarized, yet has not been rebuilt since December 2022 (1.8.7, Intel-only), and the older SmartTRAK and DataTRAK apps are Windows-only relics.
- Desktop softwareLegacy LogTRAK desktop for macOS (1.8.7)Downloads as SP_LogTRAK_macos.zip containing SCUBAPRO_LogTRAK_macos_1_8_7.dmg plus a multi-language "Read first" file; this is the only SCUBAPRO software that can talk to the cradle generation.macOS

Scubapro Meridian: common questions
Can I connect the Scubapro Meridian to my iPhone directly?
No, and no app can change that. The Scubapro Meridian transfers over serial cable only, a connection iOS does not expose to apps. Anyone promising a direct wireless download from this model is describing a different computer. The one-time cable route above gets every dive across.
Which cable and drivers do I need on a Mac?
Use the Scubapro interface cable made for this model, not a generic charging cable: the data pins differ. Most of these cables are USB-to-serial and need the driver for their chipset on macOS, usually Silicon Labs CP210x or FTDI. Install the driver, reboot, and the port appears to the desktop software.
Do I have to do this every time I dive?
Only if you want the new dives in digitally. Many divers do the cable run once to rescue their history, then log new dives directly in SeaLog on the boat, which takes about as long as filling in a paper page.
