LS423 Hardware Interfaces

this section describes the characteristics and operation of all connectors on the ls423 power connector the power connector for the ls423 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 ls423 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 ls423 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 500ma 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 the following table illustrates the pinout of the usb 2 0 type c host port pin signal name description mating sequence pin signal name description mating sequence a1 gnd ground return first b12 gnd ground return first a2 b11 a3 b10 a4 vbus bus power first b9 vbus bus power first a5 cc1 configuration channel second b8 a6 dp1 positive half of usb 2 0 differential pair – position 1 second b7 dn2 negative half of usb 2 0 differential pair – position 2 second a7 dn1 negative half of usb 2 0 differential pair – position 1 second b6 dp2 positive half of usb 2 0 differential pair – position 2 second a8 b5 cc2 configuration channel second a9 vbus bus power first b4 vbus bus power first a10 b3 a11 b2 a12 gnd ground return first b1 gnd ground return first 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) pdf version https //archbee doc uploads s3 amazonaws com/aiw58 3npddpglgjivvls aq2n 2qvxq kxpckyiaut 20250624 152135 pdf
