MB 889C (U3E1) figure

[Martino_9]

Hi everybody,

I need a figure of the 889C (U3E1) Motherboard, showing and describing every single connector on the board. Can't find any, neither in the HP Manuals nor anywhere online.

Especially I would like to identify possible on-board USB-connectors, I'd like to connect internal 9-pin USB, all I can find on the board is an 11-pin SD/MEDIA (male) und an not-in-use 20-pin (male)(blue-coloured), probably used to connect additional USB-ports with the flex port (back), currently used with an addiotional DP-port. Anyway, I'd like to know what is on the board and what it is used for. 

Thanx for help and assistance  🙂

@Martino_9,

Welcome to our HP User Forum!

This what I was able to retrieve regarding your HP EliteDesk 800 G8 Tower PC's (27P59AV) motherboard as per http://h10032.www1.hp.com/ctg/Manual/c07367256.pdf:

Hope this was helpful.

Kind Regards,

Hi NonSequitur777,

thanx very much for the help. I've already seen the board description in the technical documentation by HP, only to find that 11-PIN Socket for SD/MEDIA. Still wondering, why it's 11-PIN to connect the card-reader, which it was originally meant for, I suppose... Anyway, I tried to find an adapter in order to make 2 11-PIN sockets out of one, couldn't find any. So I just connected a PCIex1 WIFI/BT-Card with an 9-PIN female Plug (only 4 pins connected/wired) to the socket, just leaving out 2 of these 11-Pins. And it's o.k., the bluetooth connection to the mainboard ist working.

So, for now I'm fine with this solution, still I can't believe there is no photo/descreption of the board explaining ALL components and connectors/possible connections for Idiots like me  🙂 who don't know too much of computers and their interiors... again  🙂

Thanx for your time & assistance, I'll be back with another question about RAM, but not today.

Nice to be part of the forum, c u soon

@Martino_9,

Thank you for your response -incidentally, you actually helped me with the same issue.

I recently purchased a wireless WiFi/Bluetooth card, and in order to make the Bluetooth part work, you have to connect the included cable to the motherboard of my souped-up HP Z240 SFF (see picture).  To that end, I ordered a USB 3.0 20-Pin Header Female to USB 2.0 9-Pin male adapter cable to connect the Bluetooth cable to my motherboard's "Front USB 3.0" connector, but you are saying that the "SD RDR" connector works just as well!

[EDIT:] @Paul_Tikkanen, as mentioned, I'm waiting for the "USB 3.0 20-pin header female to USB 2.0 9-pin male adapter cable". My question is: am I correct to assume that I don't need this adapter, and can plug in the Bluetooth 9-pin female connector into the "SD RDR" motherboard plug?

Kind Regards,

Hi, @NonSequitur777 

That is correct.

You just leave two of the pins open.

The plug can only go one way.

@Paul_Tikkanen,

That is awesome -this Forum works both ways!

This is the kind of information I was unable to retrieve through HP.

Thank you for your kind assistance.

Anytime.

Glad to have been of assistance.

@ NonSequitur777,

Sorry for the delay on my response... Glad to find @Paul_Tikkanen joined in and confirmed the suggested solution, I hope your WiFi/BT-Card works as fine as mine does, being connected to the SD RDR / MEDIA plug. It's nice not to have to 'waste' an USB-3.0 connection for a simple BT-item...

I'm happy to learn how well this forum works, will always be glad to be back an ask for assistance for any problems or questions there will be soon, I'm afraid  🙂

Cheers,
