7i92 + 7i76 + 7i84

I am trying to configure a system with 7i92+7i76+7i84.

This is the first time I am using Mesa.

I have connected the ethernet cable

1. computer-7i92
2. 7i76RS-422 to 7i84

But I am little confused with the power connection. I want to supply separate power to each board. I have 5VDC, 12VDC, 24VDC available.
For 7i92:
As I will use separate power to 7i76, do I need to connect 5V power to 7i92??

I am using parallel port cable having 1:1 connection between DB25 ports (basically home soldered) and not shieled.

For 7i76 & 7i84:
I understand I need to connect 24VDC positive power to TB1 connector (pin 1,2,3,4 daisy chain) and GND to pin 8. Am I right??
should I daisy chain 6,7,8??

If you are using separate 5V power for the 7I76 you need to supply 5V power to the 7I92 also
(make sure the 7I76 is jumpered to use 5V external power and the 7I92 is jumpered
to NOT supply 5V to the 7I76)

Yes 1,2,3,4 are 24V on the orange field power connector on both the 7I76 and 7I84
(only pin 8 or the orange connector need be connected)

in 7i84, there is screw terminals on P5 and no terminals connected to P3.

Should I connect +5VDC to P5 top and GND to P5 bottom??

Do you mean 7I92?

Yes +5 on the top (this is shown in the 7I92 manual)

I completed power connections.
But stuck in Network..I followed this thread
forum.linuxcnc.org/27-driver-boards/3559...ethernet-mesa-boards

but on ping, its a failure.  "From 10.10.10.11 icmp_seq=1 Destination Host Unreachable" Refer attached file.
upon terminal command "mesaflash --device 7i92 --addr 10.10.10.10 -readhmid", resulted " No 7i92 board found". Refer attached file.

7i92 connected with 5VDC (4.99 VDC on measurement) power, LED status are as per attached photo and video.
All 7i92 jumpers are in default position.

What to do?? 

I think the default I.P. is in the 192.168.1.121 ish

So you have to set the jumper to the 10.10.10.10 range (its is shown in the manual)

W6 should be up

Thank you. W6 made Up and problem solved. Its pinging, attached photo. Hope it is ok.

Another query:

7i92 is connected by DB25 cable to 7i76 and 7i76RS422 connected to 7i84.

What else networking to be setup for 7i76 & 7i84??

the terminal emulator data as follows:

=======================================

it is clear that P2 connector is configured. I am forwarding towards stepper connections.
