I recommend using a hub or switch between the machine and the computer because most Ethernet cables you have lying around are patch cables. If you want to do a direct connection you will need a crossover cable:
Ethernet crossover cable - Wikipedia, the free encyclopedia
Once you have the computer connected to the machine correctly you will need to have some network settings that make sense. If you used a home router to connect the two devices then both can pull IP information from the DHCP server in the router. This sounds like the easiest way but I don't recommend it. I recommend using static IP assignments, which you would have to do if you connected the two systems with a crossover cable.
As you haven't given the exact model of the computer and the HAAS machine I will give generic instructions assuming a modern windows PC and a modern HAAS control with Ethernet option.
STATIC IP CONFIGURATION:
On the Windows PC goto CONTROL PANEL > NETWORK > CHANGE ADAPTER SETTINGS
Right Click the Ethernet adapter that is connected and select "Properties"
Select "Internet protocol Version 4 (TCP/IPv4)
Click "Properties"
Select Radio Box "Use the following IP address"
IP address: 192.168.0.2
Subnet Mask: 255.255.255.0
OK OK OK
All other settings are blank because you don't have a server.
On the HAAS machine hit the settings button
Press page down until you reach communication settings
Use the arrow keys to highlight IP Address
Type: 192.168.0.3
Press "WRITE/ENTER"
Use the arrow keys to highlight subnet mask
Type: 255.255.255.0
Press "WRITE/ENTER"
Enable access to the Hard Drive by setting it to "FULL" and pressing "WRITE/ENTER"
Now from the PC you can type the IP address of the HAAS machine in to Windows explorer and see the internal hard drive of the HAAS machine.
Open Windows Explorer and click in the address bar
Type:
\\192.168.0.3\
ENTER
Now you should see the HAAS drive with a folder called "DATA"
