There are three main issues that need to be addressed when trouble-shooting your PortDoubler setup.
1. Devices: You need to establish that your devices are fully functional when connected directly to the Macintosh.
2. Cables: The pins on the male serial connectors are very fragile, please make sure that the pins are not bent or broken off.
3. Software: The port selection in the software settings for each device has to match the port that the device is plugged into.
Determine if your device is operating correctly: Unplug the PortDoubler from the serial port on the back of your Macintosh. Plug the device in question directly into the same serial port.
Restart your Mac and hold the letter “M” key down until your desktop appears (this will prevent the PortDoubler software from loading at startup). Or using an Extension manager, disable the PortDoubler. You can also take PortDoubler out of your Extension folder and place it on the desktop.
Now attempt to use the device to see if it works without the PortDoubler. If it still doesn’t work, PortDoubler is not the problem.
• Make sure that the device is plugged in and powered on.
• Reinstall the software for the device.
• Check that the serial port in the software settings for that particular device match the serial port that the device is plugged into.
