Download and edit register settings and factory restore an Alicat tutorial
Alicat devices have shown register values on the screen for many years, and a lot of applications have taken advantage of changing them with a computer. With 8v or newer firmware versions, registers can now also be edited from the main screen. This can help to easily reconfigure a device in the field.
This article explains how to download and edit registers and factory restore a device.
Important notes
- Before changing any registers, remember to record the original value for safe-keeping.
- If using the factory restore, please be warned that this will reset all registers to the values they were the last time they were at an Alicat location. That means any changes (including calibration) done by a third party will not be saved.
Download device registers (8v/9v – serial commands)
- Download the “Alicat Serial Address Dump” zip file from our software & drivers page.
- Extract the .zip file and run it. Note that on some computers it may need to be saved due to security restrictions. Otherwise you’ll likely get an “Access Denied” error while attempting to run it.
- Ensure that your device is connected serially to the computer and powered on. Then enter the COM Port number, Baud rate, and Unit ID of your device. By default, the baud rate will be 19200, and the Unit ID will be A. In the example below, a device with the Unit ID “D” is connected to COM port 4 with the default baud rate.
- Press “Enter”, and the program will run itself and give you a “Done” message at the end. You can close the program after you get this message.
- In the same folder that the Serial Address Dump is saved, you will now be able to find a .txt file. When you open it, all of the registers and addresses will be saved.
