Option 1: Connect A Drive To Your Local Area Network - Moons' MSSTAC5 Hardware Manual

depending on how the administrator has configured DHCP. The DHCP setting is reserved for ad-
vanced users.
Your PC, or any other device that you use to communicate with the drive, will also have a unique
address.
On the drive, switch settings 1 through E use the standard class B subnet mask (i.e.
"255.255.0.0"). The mask for the universal recovery address is the standard class A (i.e.
"255.0.0.0"). One of the great features of Ethernet is the ability for many applications to share the
network at the same time. Ports are used to direct traffic to the right application once it gets to
the right IP address. The UDP eSCL port in our drives is 7775. To send and receive commands
using TCP, use port number 7776. You'll need to know this when you begin to write your own
application. You will also need to choose an open (unused) port number for your application. Our
drive doesn't care what that is; when the first command is sent to the drive, the drive will make
note of the IP address and port number from which it originated and direct any responses there.
The drive will also refuse any traffic from other IP addresses that is headed for the eSCL port. The
first application to talk to a drive "owns" the drive. This lock is only reset when the drive powers
down.
If you need help choosing a port number for your application, you can find a list of commonly used
port numbers at http://www.iana.org/assignments/port-numbers.
One final note: Ethernet communication can use one or both of two "transport protocols": UDP and
TCP. eSCL commands can be sent and received using either protocol. UDP is simpler and more
efficient than TCP, but TCP is more reliable on large or very busy networks where UDP packets
might occasionally be dropped.

Option 1: Connect a Drive to Your Local Area Network

If you have a spare port on a switch or router and if you are able to set your drive to an IP address
that is compatible with your network, and not used by anything else, this is a simple way to get
connected. This technique also allows you to connect multiple drives to your PC. If you are on a
corporate network, please check with your system administrator before connecting anything new
to the network. He or she should be able assign you a suitable address and help you get going.

If you are not sure which addresses are already used on your network, you can find out using
"Angry IP scanner", which can be downloaded free from http://www.angryip.org/w/Download. But
be careful: an address might appear to be unused because a computer or other device is currently
turned off. And many networks use dynamic addressing where a DHCP server assigns addresses
"on demand".The address you choose for your drive might get assigned to something else by the
DHCP server at another time.
Once you've chosen an appropriate IP address for your drive, set the rotary switch according the
address table above. If none of the default addresses are acceptable for your network, you can
enter a new table of IP addresses using Configurator. If your network uses addresses starting with
