ATLAS - PATIENT MONITOR - SERVICE MODE - SOFTWARE UPGRADE PROCEDURE [MEDICAL EQUIPMENT]

EXPLANATION OF AN ATLAS SERVICE SCREEN

Line A

Indicates that the Atlas is a model 220 and that the Atlas has a printer. If the Atlas did not have a printer then the text “with printer” would be absent. The date field following indicates the date the Atlas was last calibrated.

Line B

Starts with a numeric sequence. The first three digits are the model number of the Atlas. The next five numbers are the Atlas serial number. The next sequence,alphanumeric, indicates what software version is currently loaded into the Atlas. The third sequence, alphanumeric, indicates what version boot software is currently loaded into the Atlas.

Line C

Starts with the SpO2 OEM board used in the Atlas. There are two SpO2 OEM boards used in the Atlas. One is Nellcor and the other is Nonin. The next sequence indicates the model of the SpO2 board. The next sequence that starts with a letter “V” is the version software used with the current SpO2board. The date following the SpO2 software is the date  the OEM loaded the software into the SpO2board. SpO2 OEM software can not be upgraded. If the most current software is needed, you will need to replace the SpO2 board.

Line D

Is the CO2 information if your Atlas has CO2 installed. Only models 623 have CO2 installed. If your Atlas does not have CO2 installed then line Dwill be absent. If your Atlas has CO2 installed then line Dwill start with CO2 followed by a numeric number. That numeric value is the software loaded into the CO2 board. The next alphanumeric sequence, starting with a “V”, is the version of that software. The next numeric sequence starting with a “#” is the serial number of the CO2 board. The next sequence, a date, is the date the CO2 was last calibrated. The last sequence, a date, is the date the CO2was reset. CO2 OEM software can not be upgraded. If the current software is needed, you will have to replace the CO2 board.

SOFTWARE REVISION TABLE

SOFTWARE UPGRADE

NOTE:The following procedures are required to upgrade the software on a fully functioning Atlas or to reload software after replacing the CPU board. The download utility “atlas_dl.exe” loads the following files automatically.

1. atlas.out.gz
2. nvram_common.txt
3. nvram_(model#).txt
4. nvram_(language).txt

“Atlas_dl.exe” will also query the Atlas to determine what model number the Atlas is and what language to download.

Equipment or supplies required:

• PC with Windows795 or higher
• Atlas serial cable
• File: atlas_dl.exe (Included in the Atlas Repair Software listed in Table)

NOTE: Make sure you have HyperTerminal turned off or the following utility download will not work.

Run the program atlas_dl.exe from the CD or copy the file toyour hard drive and run the program from there.

• Connect the serial cable between the Atlas and the PC s’“COM1 port”.
• Turn your computer on and locate the “atlas_dl.exe” file.
• Double left click on the “atlas_dl.exe” file.
• When the file starts to download, the CRT will go blank on the Atlas.

NOTE: Do not use the computer while the program is downloading.

• After down loading is complete, check all alarm settings and all user advanced configuration settings since these are RESET by this utility software download procedure.

NOTE: Stop hereof you are just upgrading software on a fully functional Atlas monitor or if you have replaced the CPU board.

NOTE: If you have replaced the MAIN BOARD then you MUST continue with the next procedure (DOWNLOADING NVRAM FILES).

NOTE: Perform the following NVRAM downloading procedure if you have replaced the MAIN BOARD. The NVRAM resides on Main Board.
