• For an NCM, use NCSETUP to set the subnet and node
addresses. When using NCSETUP, don’t forget to specify
the correct subnet and node address for the archive device.
4. Add the device to the system database, either by updating the
DDL global file or by using a device definition window.
5. Physically attach the new NCM or PC to the ARCNET segment
that you have selected.
6. You do not need to make any changes to the Metasys Ethernet
Router or the ROUTER.CFG file. The router automatically
routes messages correctly using the subnet address for the new
device.
Moving an Existing NCM or PC to a Different Subnet
You may want to change the ARCNET segment to which an NCM or
PC is attached. This may be required because an NCM or PC is
moved to a new location or because the ARCNET cable layout has
been changed. Moving an NCM or PC to a different subnet does not
require any changes to the Metasys Ethernet Router software. To
move a device to a different subnet, follow these steps:
1. Determine the new subnet and node address for the NCM or PC.
You will probably use the same node address for the device, but
if you decide to change the node address, it must be unique.
You cannot duplicate any node addresses, even if the two
devices reside on different subnets. The device’s subnet address
will have to change to match the subnet address for the
ARCNET segment to which the device will be moved.
2. If the device is an NCM, you may want to change its archive
device. If you decide to change the archive device for the NCM,
determine the subnet and node address for the new archive
device.
3. Change the subnet and node address for the device as you
normally do.
• For a PC, set the node address using the switches on the
ARCNET card (note: PS/2 system cards do not have
switches, so PS/2 users can ignore this) and specify the
subnet and node addresses in the DDL network
configuration file.
