Troubleshooting Common Issues with the PT-JOY-G4 Joystick

April 28, 2025​

This article covers a common issue users experience with the PT-JOY-G4 joystick and how to resolve it.

The PT-JOY-G4 is the fourth-generation serial/IP controller from PTZOptics. You can find more information about it [ here ] .

Is Your Joystick Set Up Correctly?​

Before troubleshooting further, verify that your joystick is properly set up with your PTZOptics cameras.
Refer to [ this article ] for detailed setup instructions.

Have There Been Recent Changes to Your Network?​

If you recently changed your router or internet service provider, your cameras may require new IP addresses. The following articles will assist you in diagnosing and resolving IP-related issues:

  • [ This article ] explains how to check if your camera’s IP addresses are correct.

  • [This article] guides you through setting an IP address for PTZOptics third-generation cameras.

  • [ This article ] explains how to set an IP address for PTZOptics second-generation cameras.

Once your cameras have the correct IP addresses for your network, follow [this article] to reconfigure the joystick.

Serial Control: Key Troubleshooting Areas​

When using serial control , troubleshooting is typically more straightforward, focusing on four main checks.

If you are unsure how to access the camera's on-screen menu (OSD), refer to [ this article ] for guidance.

1. Protocol: Does the Protocol Match?​

PTZOptics cameras and joysticks are set to VISCA by default.

  • You can view the protocol on the joystick screen.

  • On the camera, navigate to Setup > Communication Setup Menu to find and adjust the protocol.

  • Use the joystick or camera controls to scroll left or right to change the protocol if needed.

Note: If you can navigate this menu with the joystick, you likely already have serial control.

2. Camera Address: Are the Addresses Matching?​

In serial control, camera addresses (not IP addresses) must match between the joystick and the camera.

  • This setting is found in the Communication Setup Menu .

  • Ensure the Camera Number on the joystick screen matches the address configured in the camera.

3. Baud Rate: Is the Baud Rate Correct?​

The baud rate must match between the joystick and the camera.

  • The PTZOptics default baud rate is 9600 .

  • Confirm that the baud rate displayed on the joystick matches the value in the camera’s communication settings.

Tip: As long as both devices match, they can operate at different baud rates than default if necessary.

4. Cabling: Are Your Cables Working Properly?​

Cable issues are a common cause of control loss—even new cables can be faulty.

  • If using serial daisy-chaining and control is lost on cameras further down the chain, try connecting the joystick directly to one of the affected cameras using the provided DB9 to Mini-DIN cable.

  • If a specific camera works when plugged directly into the joystick but not in the chain, the issue may be with the cabling between the cameras.

  • As a last resort, replace the cable to rule out damage or defects.

Is Your Joystick in the Correct Control Mode?​

The PT-JOY-G4 can only operate in one control mode at a time :

  • Network Mode (IP control)

  • Analog Mode (RS-232, RS-422, RS-485 serial control)

Switching between these modes is done by pressing and holding the button located on top of the joystick handle.

Important: The button placement makes it easy to accidentally switch modes during use, which can cause sudden control loss.

If You Lose Control:​

  1. Check the mode at the bottom of the joystick’s screen:

    • Network for IP control

    • Analog for serial control

  2. If the wrong mode is displayed :

    • Press and hold the button on top of the joystick for approximately three seconds .

    • The joystick should switch to the correct mode, allowing you to regain camera control.
