4-3 Initialization Settings of LONWORKS®Network

(1) System Specifications

• Up to 64 FTT-10/FTT-10A transceivers are allowed per network segment.

• LPT-10 transceivers may be used on network segments with FTT-10/FTT-10A transceivers, but are

subject to additional constraints, particularly on distance.
See the LPT-10 Use's Guide for more information.

• The average temperature of the wire must not exceed +55˚C (+131˚F), although individual segments of
wire may be as hot as +85˚C (+185˚F).

The free topology transmission specification includes two components which must both be met for proper
system operation. The distance from each transceiver to all other transceiver and to the termination
(including the LPI-10 termination, if used) must not exceed maximum node-to-node distance.
If multiple paths exist, e.g., a loop topology, then the longest path should be used for the calculations.
The maximum total wire length is the total amount of wire connected per segment.

For details, refer to “ FTT-10A Free Topology Transceiver User's Guide ” of Echelon Corporation.
For reference, the system specifications and Transmission specifications are described.

If being used together with system controller, perform the initialization settings.

3

The units will be idle until the LM ADAPTER initialization has been completed (LED002 goes out).

* This requires approximately 5 to 10 minutes.(If being used together with system controller, it will be approximately
3 minutes after the completion of the initialization settings.)

If you connect the power to the LM ADAPTER before connecting the power supply to the units, the LED002 might stay lit.
If this case arises, reset the power supply to the LM ADAPTER.

4

Confirm that the LM ADAPTER’S maintenance LED (LED003, 004) are not lit.

* If the LM ADAPTER’S maintenance LED (LED003, 004) are lit, refer to the next chapter “6. Troubleshooting”.

(Note 1) Always refer to the previous chapter “4. System settings” before changing the system configuration,
such as the M-NET address.
* After confirming the above details, always refer to the following section “ 5-4 Test Run ” and make confirmations

with trial operations.
