if you need to open the OSD of your camera using the serial joystick you can do this by calling preset 95. this can be done by pressing the "call" button then 95 on the keypad and finally enter. make sure you are able to see an active video feed in order to navigate this on-screen menu. once in the onscreen menu the joystick itself is used to move the cursor and the "IRIS+" is used for the enter button and the "IRIS -" is used to go back. please keep in mind that for some things that are changed on this onscreen menu the camera may have to be rebooted after and that the serial joystick has no way of doing this.
