How to Turn Around an OASIS3 Can

When an OASIS3 can is recovered from a deployment, you'll want to make sure the data is recovered, and then make it available to reprogram for a new deployment. Also see Post-Deployment Checklist, which documents procedures for the shore-side data processing.

Data Recovery

Normally, the data is fully recovered by the hourly downloads. If you're sure that all data is accounted for by this method, you can ignore this section.

If you want to get all deployment data, perhaps just as a backup, you can use one of two procedures.

1. The easiest way is to use the Ymodem send command YS from OASIS3. (It's also the most secure, as Ymodem has CRC checks).
• Set up the can, connect power and serial cables, and use a terminal emulator that supports Ymodem, such as Hyperterminal or ProComm (unfortunately, MotoCross doesn't support Ymodem).
• Turn on power and/or hit the reset button (short reset). You should see the "OASIS>" prompt. To shorten the download time, set the baud rate to 115200 via the drvparm command (select option 2, baud rate).
• Quit OASIS3, and set your terminal emulator to 115200 baud.
• Hit the reset button again (short reset). You should see the "OASIS>" prompt again, but running at 115200 baud.
• Type YS OAS?????.*
(or YS OAS*.*, but you may get a few additional files. No harm).
• At your terminal emulator, choose receive file and then Ymodem batch or Ymodem-G.
• The terminal emulator Ymodem screen should indicate when you're done. At that point, you'll have all the OASnnnnn.DAT and OASnnnnn.IDX files on your local PC. The OASnnnnn.DAT files can be directly decoded or extracted using "decode -b <filename>" or "extract -b <filename>". Note that you don't really need the .IDX files, unless you want to move the data to another OASIS3 system.
2. Another method is to use the dump command from OASIS3.
   • Set up the can, connect power and serial cables, and use MotoCross or similar terminal emulator. MotoCross should be set for 9600N81 by default.
   • Turn on power and/or hit the reset button (short reset). You should see the "OASIS>" prompt. To shorten the download time, set the baud rate to 115200 via the drvparm command (select option 2, baud rate).
   • Quit OASIS3, and set MotoCross to 115200 baud (File-> Communications Settings-> Baud Rate).
   • Hit the reset button again (short reset). You should see the "OASIS>" prompt again, but running at 115200 baud.
   • Turn on capture mode (Transfer->Capture Text in MotoCross)
   • Type dump 0, 65536 to dump all data (or see what the max blk number is via logs).
   • Turn off capture mode.
3. Alternatively, with power off, remove the OASIS3 CPU card. Remove the CFM card. Put the CFM card into a CFM reader on your PC, and copy all files named "OAS0*.* As in (1) above, these files can be decoded or extracted using "decode -b <filename>" or "extract -b <filename>".

Preparing for New Deployment

Once you're sure you have all the data, preparing the OASIS3 controller for a new deployment is very easy.

1. Set up the can, connect power and serial cables, and use MotoCross on your PC.
2. Turn on power. When you get the "OASIS>" prompt, type reset pico. That should bring you to the PicoDOS prompt.
3. Erase all "OAS0*.* files.

You're now ready to configure the can for deployment. See How to Configure an OASIS3 can for Deployment.
