DP83848 pinos 3 e 4 nao respondem a ping

Dagoberto,

Which DP83848 variant are you using?  Could you provide a schematic for review?

Patrick

Thanks for the reply

I ask your help to clarify whether the DP83848CVV  this working properly!

 I'm trying to make the circuit respond to a PING and is a server-page (same circuit-Ethernet Kit Microchip)

I see:

1) The pin 27 always on.

2) The pin 28 always on

3) The pin 26 off lights when transmission has

4) The WIRESHARK shows Microchi_71: 90:69 ( This indicates that the PIC passed information to the DP83818  ?)

I believe the DP83848 is working properly.

I ask your help where should I focus on where (in DP83848)  to find the problem:

 example: 2,3,4 pins (TX) or 43.44 (RX)

NOTE-1: I read your comments that pins 18.37 -> 23  should measure 1.87v. but has 1.5v.  how can I to make up to 1.87v?

NOTE-2: The PIC   IP Adress: 169.254.1.1 MASK: 255.255.0.0 GATE: 169.254.1.1 DNS: 169.254.1.1

MY PC:   IP Adress: 169.254.1.10 MASK: 255.255.0.0 GATE: 169.254.1.1 DNS: 169.254.1.1

These data do not mean anything to see if the DP83848 is working properly?

NOTE-3: Excuse my ignorance.

1) If the WIRESHARK shows Microchi_71: 90:69 this means that the PIC 'talks' with the DP83848

   So the problem is that the DP83848 not 'talk' with PIC , or the PIC is configured \ programmed or problem in circuit PIC

Dagoberto.
