This section describes the characteristics and operation of all connectors on the LS425 and LS445.
LAN/Ethernet
This connection is used to connect an ethernet cable for internet access. The LS245 and LS445 wired ethernet connection is capable of 10/100 Base-T Mbps.
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)
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.
3.5mm 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
IR Input/Output
The 3.5mm IR in/output is via USB-C.
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 Antenna Connectors
The LS245 and LS445 have a two SMT type SMA connectors and an M.2 connector to allow easy installation of external WiFi antennas. Both devices contain an internal M.2 PCIe card for an optional module that enables WiFi/Bluetooth.
