唔係問我借...Cvincent 話佢自己的 lan cable pin assignment 係 18, 27, 36.... o個種, 唔係你俾佢o羊 ?
The lan cable is borrowed from the estate web friends  .... who helped me to do a straight-thru cable. However, I need to return it to him afterward......

Rainbow cable contacts are fine ! so where is the problem ????
can't tell what is wrong at the moment.

however, i have some unpleasant experience using those "crimp pin" sourced locally.

if direct soldering those cables still fail, give me a shout.

Thank you so so so so for your great support as always! Same appreciation to 板大!
I will bring my laptop, power supply, lan cable as well as the usb box together.
hopefully, we can figure out where is the problem.

I use the original molex plier to make the cable and check all conection are fine, I tried update the board firmware in another computer, I will try it in my home computer tonight.

USB SPDIF is not compatiable with Kapaersky Anti-virus software, Need to disable when installing.....

Thank you so much to 板大 for your help, now my USB SPDIF box is working (only AES but not I2S).
Now I connect the power input for USB SPDIF box directly from the 昇頻板 電源位 在1955 PRo 内取電
, 輸出為7.9V - 8.0V,  估計應該是 A 不足 so it's only AES works, I2S still doesn't work that I think.

話好危險,個到有 CPU, VFD, 昇頻,加 USB, 成 1A loading....

i2S 唔 work, 和電流無關系,都係 cable 問題!

剛已disconnected!並發現了原來供電比display的block牛是有2組9V 18VA 2AT 輸出的,現只用了一組比1955pro 的display。
請問另一組可否加片隱壓板比電USB SPDIF 盒呢?

TOP

這樣最好!

it's cool.

btw, did you solve the display problem?

TOP

個case好靚仔呀!

TOP

對呀!個case係由一塊鋁摺成的
顯示方面問題相信已解決,thanks !
不過,個case係冇i2s o架....因為我冇呢塊板o羅

TOP

無i2s無問題,用到192k 咪ok囉!

同軸可直出到192k 到 Wm8741.. 要試384K 要搵下dac先得了
現在左後的角落是AES接口,可能改此接口為 i2s LAN 插

另外,發現顯示方面仍有小問題

48k,96k 顯示正常


但是44.1k, 88.2k, 192k 顯示不正常, 聲音正常.
17xk 更出不到聲(不過可能是dac的問題)







不知何解 ...

have you tried soldering the wire directly?

it seems to me it's still cable problem..........

TOP

All wires tested OK, solder the wires and test later

TOP

原來是針與座之間接觸不良, Thanks mdlover !
另外, i2s 也試驗成功 !

一定要試聽 I2S,有餘韻得來又直接,相比之下,Co-axial 好似多左的霧。
昨天又試左的精神線,真係會精神左好多,如要更上一層樓,呢個係唔錯 upgrade....
上圖先.....

版主唔止線用精神連输入電容都精神

真奇怪,現巳從9V block 牛直接取電,經穩壓板8V 比電 usb spdif 盒,但I2S仍用不到,不知道那裡出問題?
