Firmware Update
System Firmware
The system firmware (S37) is the most common type of update. It’s a small file and doesn’t take too long to
update.
In the 232-ATSC+1, you won’t need an RS-232 port. Just download the .zip file from our website, open the
ZIP folder, then copy or drag the file to a pop-up file window, just as if the tuner was a memory stick.

HD Load Processor Firmware
This firmware process updates the HD processor in the 232-ATSC+SDI; it’s a much larger file and uses a
different set of steps for updating.

folder in C:/CR Temp when you click OK on the pop-up window.
Connect an RS-232 null modem cable from your Windows PC to the RS-232 input on the back of the
tuner. The data rate of the update is too fast to use the USB connection on the front of the tuner.
Remove the 12 VDC cable from the back of the tuner.
Go to the CR Temp folder and run HDLOAD.exe app.
Select the COM port you’re using from the pull-down list at Connection. Don’t select Enable
Dynamic 2X Speed as an option. On some PCs, you may need to go to Control
Panel/System/Hardware manager, right-click the COM port, and select Update Driver.
Keep the default settings, Model=TL9xx, Data Type=Application

difficulty downloading, try updating the driver for the USB adapter, use a different adapter, or retry
the process a few times.
The Message text will tell you when the process is complete. Close HD Loader reset DC power to the
tuner.
