Router Option Card for Lon® Star Coupler
RER 111
Once the router option card has been programmed, the fibre-optic mode can be
configured for router side A, if required. To enable this, the communication
parameters must be set from router side B. In the fibre-optic mode, the following
items must be programmed for router side A, for example, by using LNT:
- communication speed
- communication port mode, i.e. single-ended, direct mode.
- other parameters related to communication on the L
parameters in the configuration structure.
1RWH If a parameter value has to be changed, extreme care should be taken, because
!
all parameters are stored in EEPROM memory in the RTR-10 core module and
incorrect settings may cause severe damage to the RTR-10 core module, or even
destroy it completely.

Now the router is logically installed in the system, but it is not programmed. The
router operates as a repeater and it will pass on all messages regardless of the
addresses of the messages.
Next you can program the router to operate as intended. Figure 1.-2, for
example, illustrates a system with two subnets and one router option card. Now
we program the router in the system so that it only forwards messages that are
sent to another subnet (e.g. if node X in subnet 1 sends a message to node Y in
