If your GS1000 is USB type

• Make sure the cable is purchased from GIGA-TMS. The cable produced by other brands or made by yourself may not be able to work with GS1000.
• Make sure the power switch of GS1000 is set to on.
• Make sure GS1000 is not communicating with our other software at the same time.
• To communicate GS1000 with the software, GS1000 must enter communication mode. Under communication mode, SCAN LED of GS1000 should keep flashing slowly. If GS1000 is idle over 3 minutes, it will be turned off automatically to save power. Just press the SCAN button to enter communication mode.
• Make sure the “Comm. Port” selection in the software is correct.
• Make sure the driver is installed.
• If you have installed the driver, once GS1000 is connected with your computer, go to [Control Panel]\ [System]\ [Hardware]\ [Device Manager]\ [Ports (COM & LPT)] and see if “Prolific USB-to-Serial Comm Port (COM number)” appears. “Prolific USB-to-Serial Comm Port (COM number)” showing indicates the driver is installed correctly. However, if (1) “Prolific USB-to-Serial Comm Port (COM number)” doesn’t appear (2) “Prolific USB-to-Serial Comm Port (COM number)” appears with an exclamation mark, or (3) it shows “USB Device” with an exclamation mark, see How do you remove the old driver and install the new driver (USB type) to remove and install the driver again.
• The older driver may not be able to support the newer GS1000. If “Promag USB232/422/485 (COM number)”appears under [Device Manager]\ [Ports (COM & LPT)], it indicates the older driver is installed. Contact GIGA-TMS for the latest driver. Then see How do you remove the old driver and install the new driver (USB type).
• Make sure there are not Bluetooth devices installed in your computer.
• Make sure USB port of your computer is workable. Try to use different USB port to connect GS1000 with your computer or test USB port with other USB devices.
• Try the other cable produced by GIGA-TMS if you have more than one cable.
