Choosing an MDI connection method for SPS

Choosing a MDI connection method for SPS - connections GM MDI scanner are critical to the success of the programming module. Reliability takes precedence over convenience, to keep it simple. Connect the MDI directly to the Techline PC via the USB cable is recommended in order to maintain an error-free connection between the PC module and vehicle (through MDI and DLC). This method is simple, easy and eliminates any potential problem for a network of interfering during the transmission of data to the module during programming.

Quality / Reliability store network (LAN) - Wi-Fi hardware used by utilities varies greatly and is difficult to qualify. Techline recommends hardware for Business Grade Wi-Fi access points (AP). Hard-wired cable connections to the LAN are considered more reliable than Wi-Fi and may be more suitable if not near a reliable Wi-Fi connection. Note that the cables are still prone to physical damage, such as the deterioration of the cable or connector, which is not always visually apparent. If a cable is suspected, replace another cable.

If you connect them using wireless ethernet, you should make sure that wireless is enabled and IP configuration is properly configured using the MDI Manager software. So what you need to do is check if the USB cable is not connected, the GM MDI is not being used via Ethernet wired and the wireless card is properly seated in MDI. You can contact the IT department and see if your PC is detecting the wireless access point and the correct security settings have been configured for MDI.

And if you connect, then using wired Ethernet, you need to ensure that the Ethernet wired communication is enabled and configured using the MDI Manager software. Then you should check that the USB cable is not connected and the MDI device detects Ethernet activity wired displaying the flashing lights on the Ethernet port wired MDI. And also you can contact your local IT department and make sure the MDI and the PC are on the same subnet.
