For those of us who are not network experts, it can be a challenge to communicate with those who are. Here are some basic rules to keep in mind when setting up a small local series of devices that will be communicating over a network:
Know the IP range you are working in.
Devices are assigned IP addresses, typically managed automatically by the router (DHCP) but can also be assigned static IP addresses. In order for devices to communicate, they need to be in the same IP range - a group of IP addresses set to a group. This range can be identified by looking at the IP address of your primary device and the subnet mask set on the router. You can use this simple calculator to help identify the IP range.
Build a good relationship with the IT department in charge of the location.
This may seem obvious, but these are the guys/gals that will be getting things done for you. Many times, whatever it is you do, you and IT department approach problems very differently for different reasons. Making sure you are patient and constructive with your questions will go a long way.
Set up remote access from the beginning.
Chances are something will go wrong; having a remote access and service plan is key to maintaining a successful program.
