Does anyone know if the command failed fix requires new firmware for the TSU, RFX or both units? I've done the update on one of my TSU9600's and re-downloaded my same config to it using the new PEP2. It is working better, but I am still seeing failures. I have not had a chance to update the firmware in the RFX9600 yet and am wondering if anything was done there to help with the problem.
