the same subnet, the message will not be passed on to subnet 2. But if node X in
subnet 1 sends a message to node Z in subnet 2, the message will naturally be
passed on to subnet 2). This is done by changing the routing algorithms of the
router.

The default router algorithm is a repeater.

The configured routing algorithm enables two buttons at the bottom of this
window. The routers in this system either forwards or drops messages
depending on the destination subnet. Therefore you have to set the
IRUZDUGLQJ
IODJV
in the routing table.

The router has two sides and so the routing table has two sides too:
WKLVVLGH
and
the
IDUVLGH
. A check-mark in a box indicates that a message addressed to the
subnet should be forwarded. So, when subnet 1 has a check in the
WKLVVLGH
box,
for example, messages addressed to subnet 1 will be passed through the router
from
WKLVVLGH
to the
IDUVLGH
.
In the example system in figure 1.-2,
WKLVVLGH
is an open-collector bus on the
mother board and the
IDUVLGH
is a fibre-optic interface. Which side is which
depends on where the management node is connected. In this system, the
management node is connected to the open-collector bus of the router.

Next you have to verify that the Neuron chip structures are right on both router
sides:

You will get the Neuron Structures, Near Side window.

You will see now Neuron Structures, Far Side parameters.
In this case the far side (router side A) is the fibre-optic interface. Thereby it is
important that the configuration structure parameters are as mentioned in the
Appendix A, Table 3 of this manual.
Especially check the following values and change them if needed:
