The Canon EOS 40D is a Hi-Speed USB 2.0 DSLR camera and compatible with the TetherPro USB A to Mini B 5 pin cable (Canon IFC-400PCU compatible). Available in high-visibility orange or black, the TetherPro cable features gold-plated connectors for corrosion resistance, ensuring consistent and reliable conductivity. A ferrite core is also included to filter out signal noise and reduce transmission errors. Additionally, all TetherPro cables are fully shielded to protect against external signal interference.
The TetherPro USB A to Mini B, available in various lengths including 15 feet (4.6m), connects to the Canon EOS 40D via the USB Mini-B port located on the side of the DSLR body. This cable is designed and manufactured to highest USB specifications, ensuring delivery of excellent performance.
USB specifications recommend limiting the length of a passive USB cable to 15 feet. If you plan to tether your camera longer than 15 feet, you will need an active extension. USB Active Extension, available in 16, 32, 49 or 65 feet (5, 9.7,15 or 20m), used in conjunction with your passive USB cable, will boost the signal, reduce transmission errors and lower noise, enabling the longer tethering distances when needed.
