Note: If the Ethernet network consists of multiple Ethernet

segments, the segments must be connected using LAN

Routers that support the TCP/IP protocol suite.

Intermediate networks that use other communications

technology (FDDI, Token Ring) are acceptable if the

intermediate networks are high speed. Low speed

networks (e.g., 9600-baud serial lines) will cause

unacceptable delays to the Metasys N1

communications.

The resulting network layout will be similar to the sample

network shown in Figure 3. Each ARCNET segment will have

one Metasys Ethernet Router attached to it. The ARCNET

node address on each Metasys Ethernet Router has been

preassigned 255.

3. Assign a subnet address to each ARCNET segment. We

recommend using the subnet address “1” for the primary

ARCNET segment, or the segment that has the most devices

attached to it. Assign a unique node address to each NCM or

Operator Workstation attached to the N1 network. Node

addresses must be unique even if the NCMs are attached to

different subnets. Record the subnet and node address

information on the Metasys Ethernet Router Planning Form A.

(See Appendix A: Metasys Ethernet Router Planning Forms.)
