How to configure PuTTY

PuTTY is a commonly-used serial terminal program that you can use to communicate with your Alicat over RS-232 or RS-485. The instructions below explain how to configure PuTTY for optimal communications with your Alicat instrument.

1. Download PuTTY from puttykey.com and run the installer.  
    
2. Open PuTTY; it will start on the Configuration screen shown below

3. Click on the Terminal category. The changes we make here will cause PuTTY to act like a normal serial terminal, such that pressing enter will move the cursor to the next line and both what you type and what gets returned stay on the screen.

1. Check the box that says “Implicit LF in every CR.”
2. Select the “Force on” radio button in the “Local echo” section.

4. Click on the Connection category and then the Serial subcategory.

1. Set the Speed (baud) to 19200.
2. Set the Data bits to 8.
3. Set the Stop bits to 1
4. 4. Ensure that “None” is selected for both Parity and Flow control.

5. Click on the Session category.

1. Select the “Serial” radio button in the “Connection type” section.
2. Check that the selected COM port and baud rate (Speed) are correct.

6. Save your settings so they can be recalled again later.
