1. Description
================================================

Firmware version 1.13
This firmware update applies to both standard and OEM versions.

This firmware update resolves an issue that can occur only in
multithreaded Universal Library applications coded such that a
background scan is not stopped from within the same thread it was
started in. In this scenario, the device can become unresponsive.  

This firmware update is compatible with hardware revisions A through E. 
Do not install this update on devices with a hardware revision greater 
than E. A label on the device identifies the revision. The letter just 
before the dash denotes the hardware revision. For example, part number 
151440E-xxL indicates revision E. If an update for revision F
or greater is available, it will be found in a separate location.

To determine the firmware version currently installed on your 
USB-1608GX, run the InstaCal utility provided with the MCC DAQ software.
Double-click the device to open the Board Configuration dialog.
The currently installed firmware version is displayed in the 
lower right corner of the dialog.

Firmware update procedure:

1. Download the 'USB-1608GX.iic' file and copy it to the FirmwareImages 
   subdirectory of the DAQ installation directory 
   ("Program Files\Measurement Computing\DAQ\FirmwareImages" by default).
2. Connect the USB-1608GX to your computer.
3. Run InstaCal and click the Download Firmware toolbar icon to open the 
   Firmware Loader dialog.
4. Click the Load Firmware button to start installing the firmware. 

After the firmware is installed, the Status field displays "Firmware 
update completed", and the Device firmware version field displays the 
firmware version installed on the device. 

Click the X in the upper right corner to exit.

3. Updating firmware using DAQFlex
================================================

Determine installed firmware version:

To determine the firmware version currently installed on your 
USB-1608GX, run the DAQFlexFWLoader.exe provided with the DAQFlex 
for Windows software. The currently installed firmware version 
is displayed in the Device firmware version field.


Firmware update procedure (must be done on a Windows PC):

1. Download the 'USB-1608GX.iic' file and copy it to the 
   FirmwareImages subdirectory of the DAQFlex installation directory 
   ("Program Files\Measurement Computing\DAQFlex For Windows\FirmwareImages"
   by default).
2. Connect the USB-1608GX to your computer.
3. Run the DAQFlex Firmware Loader utility DAQFlexFWLoader.exe from
   C:\Program Files\Measurement Computing\DAQFlex For Windows.
4. From the Device drop down list select USB-1608GX.
5. Click the Load Firmware button to start installing the firmware.
