LS424 Hardware Interfaces

this section describes the characteristics and operation of all connectors on the ls424 power connector the power connector for the ls424 is a usb micro b port rated for 5v\@2a the connector is used for power input only—it does not transfer data rj45 lan the ls424 has an rj45 connector for 100base tx networking the maximum length for cat 5e cable is 100 meters; the allowed length can be higher or lower depending on the quality of the cable usb the ls424 has a usb 2 0 type c port, which is capable of transfer speeds up to 480 mbit/s the usb connector can supply up to 0 5a of power for peripherals the maximum length for a usb cable is 5 meters the usb type c port will output analog audio if the cc1 or cc2 signal is shorted to ground via a 1k resistor analog output can also be enabled in system software the dp signal outputs right audio, and the dn signal outpts left audio usb 2 0 type c pinout the following table illustrates the pinout of the usb 2 0 type c host port usb serial the serial port supports ttl signaling and is located on the the a2/a3 and b2/b3 pins it enumerates as port 0 the serial port is disabled by default it can be enabled/disabled by writing to the player registry using brightscript (via roregistrysection docid\ ffm73tjd bthw4 p 0jvg ) or javascript (via registry docid\ txwoombd2 u12dfegx7ga ) enable serial registrysection = createobject("roregistrysection", "usb") registrysection write("type c serial","1") disable serial registrysection = createobject("roregistrysection", "usb") registrysection delete("type c serial") the serial port can also be enabled by accessing the brightscript debug console docid\ ywksi6x 2hez1bwztfhmp but, unlike the above method, the serial port will not remain enabled after a reboot hdmi output the hdmi ® output is an hdmi 1 4a connector used to send digital video and audio to hdmi enabled sink devices it is capable of outputting a maximum video resolution of 1920x1080x60p the following table illustrates the pinout of the hdmi connector pin description pin description 1 tx2p 2 ground 3 tx2n 4 tx1p 5 ground 6 tx1n 7 tx0p 8 ground 9 tx0n 10 txcp 11 ground 12 txcn 13 cec 14 nc 15 ddc scl 16 ddc sda 17 ground 18 +5v ddc 19 hpd (hot plug detect)
