How to Connect Acromag Series 9xxEN Modules Via RadioLinx Ethernet Modems
The purpose of this document is to provide a procedure for connecting an Acromag Series 9xxEN I/O Module to an existing network via RadioLinx Ethernet Modems.
Background – IP Addresses
Any TCP/IP packet contains two addresses: a unique fixed MAC address, and a unique IP address.
To communicate on the Internet, computers must have unique identifiers in order to differentiate one computer from another. This is accomplished through the assignment of an IP address. An IP address is a 32-bit identifier comprised of 4 octets (8-bits), with each octet a number from 0 to 255 and separated by a decimal point. For example, Acromag Series 9xxEN I/O Modules use a default IP address of 18.104.22.168.
Every host on a network must have at least one unique IP address. A personal computer with more than one network interface card (NIC) will have a unique IP address for every NIC card installed, as each NIC card may function as a node on a network. Additionally, all hosts on the same physical network must have the same network prefix.
