Overlay mode - LSM 3.5 SP3 Business + Prof.
Overlay mode can only be activated in the G1" or "G2 + G1" protocol generations.
Overlay mode provides a very convenient feature for the restricted G1 protocol generation: the option of using newly programmed transponders directly without reprogramming the locking device. However, this feature only functions for up to 7 newly added transponders.
In the G2 protocol generation, such programming can be carried out using a transponder or a locking device.
7 further transponder IDs are added for each transponder ID if overlay mode is enabled:
Transponder IDs start at ID 64
- Transponder 1 with transponder ID 64: The Transponder IDs 65 - 71 are also reserved.
- Transponder 2 with transponder ID 72: The Transponder IDs 73 - 79 are also reserved.
- Transponder 3 with transponder ID 80: The Transponder IDs 81 - 87 are also reserved.
- and so on.
Example – replacement transponder: A replacement transponder needs to be programmed for Transponder 2 with Transponder ID 72 due to loss or theft. This replacement transponder is assigned the reserved Transponder ID 73. If the newly programmed replacement transponder is operated on an authorised locking device, the locking device engages and the "old" transponder 2 with Transponder ID 72 is blocked from use on the locking device. The process can be completed with a corresponding feedback signal to the LSM software.
It is possible to hold up to 1,000 transponders in reserve in this way.
