6.3. Programming of the SLTA option card
Before the SLTA option card is ready for use in the L
ON
W
ORKS
network it has to be
configured by the user. The SLTA option card is configured from the host device via
the RS232 interface by the use of a network management program e.g. LON
Network Tool (LNT). All configuration information is stored in the EEPROM
memory of the Neuron chip located in LTS-20 core module.
To facilitate the easy implementation of the system, the SLTA option card is
programmed by the manufacturer. However, the option card has a network address
which should be programmed by the user before the card is used in the L
ON
W
ORKS
network.
The network address consists of a node number and a subnet number. A new address
will take effect immediately after a change.
By default the node number is 127 and the subnet number is 1.

If any other parameter value is to be changed extreme care
should be taken account, because all parameters are stored in
EEPROM memory in LTS-20 core module and incorrect settings
may cause severe damage to the LTS-20 core module or even
destroy it completely.
