The LS425 and LS445 wired ethernet connection is capable of 10/100 Base-T Mbps. 802.1x is supported on the ethernet port, but not on USB-connected ethernet devices. # Power Connector The power connector for the LS425 and LS445, which connects the power cord to the device, is rated for 12V\@1.5A. The connector is used for power input only—it does not transfer data. # HDMI Output The LS425 has full HD HDMI**®** output and the LS445 has a UHD/4K HDMI output. The LS425 is capable of outputting HD video (up to a maximum video resolution of 2048x1048x60p), while the LS445 can output 4K video resolutions (including 1920x1200x60p, and up to 3840x2160x60p). # IR Input / Output The 3.5mm IR in/output is via USB-C. # Audio Connector The LS425 and LS445 have a dedicated 3.5mm combination analog/optical audio port. To transmit a digital audio signal, use a TOSLINK optical audio cable with a 3.5mm connector. Analog and digital audio cannot be transmitted simultaneously. The full-scale voltage output of the analog audio is 2V RMS. The minimum load impedance is 32Ω. The analog audio connector has the following pinout: - **Tip**: Left audio - **Ring**: Right audio - **Sleeve**: Ground for audio signal # USB-C A USB-C 3.0 port connects to USB-compatible devices. The USB-C port supports both device and host mode, and supports custom cable solutions such as USB-C to GPIO cable, USB-C to USB-A and 3.5 serial cable, and USB-C to IR. # WiFi & Antennas The LS425 and LS445 models come equipped with an M.2 connector slot and two SMT-mounted SMA connectors. The M.2 slot supports M.2 PCIe cards for WiFi and Bluetooth connectivity (sold separately), while the SMA connectors facilitate the connection of external antennas.
