Mesa 7i92+7i76+7i85S

Hi,
start to connect this setup for my lathe.
First problem about wiring
7i92 connect to 7i76 without problem.
But 7i92 to 7i85S I have problem. Buy separatery idc connector with cable and Dsub for connect with them.
Please look the foto and tell me this connection is ok?

That looks correct, what problem do you have?

I connected and for now all working.
 

After install linuxcnc 2.8.2 want change network settings for 7i92 but is instaled nm-tray and when want open settings dont do anything.
Want install gnome but when write in terminal
apt-get install network-manager network-manager-gnome
Got E; unable to locate package network-manager-gnome
When try
apt-get update after

I would probably side-step the GUI network tools and setup the real time link
by editing the interfaces file as explained in the hm2_eth manual page

man hm2_eth

Forget write
ifconfig and iwconfig didint work to...
After add to file interfaces;
auto eth1
iface eth1 inet static
address 192.168.1.1
hardware-irq-coalesce-rx-usecs 0
and try  mesaflash --device 7I92 
Got No 7i92 board found

What does

ip a

report?

edi@debian:~$ ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

2: eno1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
link/ether 08:2e:5f:20:95:65 brd ff:ff:ff:ff:ff:ff

inet6 fe80::a2e:5fff:fe20:9565/64 scope link noprefixroute

Right, so the actual Ethernet device name is eno1, not eth1

After change eth1 to eno1 in interfaces file
still mesaflash --device 7i92 No board found
