If you're getting a “Driver failed to start” or “DVR API error” messages from Streams5 and you can't enable the devices, you'll probably need to reset the flash on the DVR boards

• Open up the console, navigate to the directory where you have the diagnostic tools for CL160 installed (most likely, C:\\Program Files\IO Industries\DVR Express\CL160\) and run the command flshprog flsh160.bin

• You will see a progress bar on the screen telling you that the program is updating flash on a certain device. Wait for this to finish.

• Next, program the acquisition modes by executing the command jtagprog acqmodes\009-400-acq (highlighted in red). If you try to program an incorrect acquisition mode, jtagprog will tell you that the mode is incorrect.

• First, the program will erase the acquisition mode

• Then, it will write the new mode to the boards
