PUMP Updater (Mac)

PUMP Updater (Windows)

It is not necessary to have PUMP inserted in a 500 Series rack to perform the firmware update. Empirical Labs recommends removing the PUMP from your rack prior to updating. Doing so will make accessing the USB port much easier.

Step 1: Download Latest Firmware - v3.01

The latest firmware version is always included in the download links above.

All firmware versions can be downloaded here: https://www.empiricallabs.com/pump/#firmware

Download includes:

PUMP Updater (i.e. “PUMP Updater.exe”)
PUMP Firmware File (i.e. “pump3.01.hex”)

Step 2: Plug USB cable into Computer

Step 3: While holding Bypass (BYP) button, plug USB cable into PUMP

The BAD and AtMod LEDs will be lit to show that PUMP is in Bootloader Mode.

Step 4: Open PUMP Updater

WINDOWS USERS Your antivirus software may stop the application from loading the first time.

If the application does not run after following the steps below, try restarting your computer.

Click "More info"

Click "Run anyway"

MAC USERS You may need to navigate to your "Security & Privacy" settings and click "Allow Anyway" for the application to run.

Click "OK"

Open "Security & Privacy" settings in System Preferences, then click "Open Anyway"

Click "Open"

Step 5: Click "Open File" and select PUMP Firmware File

Step 6: Select PUMP from Device Dropdown Menu (Port Options)

WINDOWS USERS PUMP shows up as "COM###" (Make sure to ignore COM1)

If you do not see your device, press the "Refresh" button then repeat step 3.

MAC USERS PUMP shows up as "/dev/cu.usbserial-###"

If you do not see your device, press the "Refresh" button then repeat step 3.

Step 7: Press "Start" and wait!

Upon completion, PUMP will automatically boot up with the installed firmware.
