Appendix 4 Network Function of Embroidery Machine
Network
2.3 Subnet mask
To show how the network number and computer number are divided, subnet mask is
used to tell in one IP address which part is for network and which part is for computer. It's
regulated that "1" is for network part and "0" is for computer part. IP address and subnet mask
combine to tell in which network the computer is. So the subnet mask is very important. If it's
wrong, it will get the wrong network address. Therefore the same network number must be set
with the same subnet mask.
2.4 Gateway
It's the IP address of the router which is in the same subnet of the computer. As in the
followed picture, if one data package needs transmitting to a computer in network 2, this data
package has to be sent to the router linked to us. It's like in sending by post, you only need to
deliver a letter to postman instead of delivering by yourself. So when the computers are not in
the same network segment, the gateway also has to be set properly in setting computers.
Otherwise computers don't know where to deliver the data package.
3 The ways to construct network
3.1 One PC directly connected to one embroidery machine
In this situation crossover cable is used to link the network interface of PC and the
network interface of embroidery machine.
