LNET General Purpose Input module. Provides 8 GPI inputs (voltage free momentary contact closure) for interfacing LNET to BMS or relay controls.

The LNET range of products from LSC lighting offer an extension to the functionality of the EKO and ePlates network. LNET is the backbone communication system which the EKO, TEKO and e24v2/v3 dimmers, LNET interfaces, Houston and ePlates use to talk to each other.


LNET Modules

  • LNET232 – an RS232 to LNET interface. This module will allow an RS232 based system to send messages into the LNET network so as to trigger system wide memories.
  • LNET/EIM – an External Interface Module. This module will allow momentary action dry contact closure systems (such as cinema projectors or BMS systems) to trigger memories inside the LNET system.
  • LNET/HUB – a device which allows the normally daisy chained network to be a star connected network. This module is particularly useful to optimise cable routing in larger systems.
  • LNET/USB – a module to convert USB data to the LNET system. This module is used with a computer when programming the system (using toolbox software) and monitoring the system (using Houston).
  • LNET/PSU – a power booster module which is used to supplement the network voltage for larger or longer cable runs.

All these modules work together with the EKO/TEKO/e24v2/v3 dimmers, Houston and ePlates to form small and simple networks to large and complex networks. They assist with system diagnosis and isolation when required and help to solve certain network logistics issues which can sometimes degrade the system performance.


LNET Module Features

  • All modules are housed in standard 6 DIN Module wide case suitable for TS35 DIN rail mounting.
  • All modules are fully compatible with the LNET network of EKO, TEKO, e24v3/v3 dimmers, Houston software and ePlate wallplate controls.
  • Line powered from the combined power supplies with the EKO dimmers or from the LNET/PSU module.
  • LNET/232
    • Provides RS232 interface for B.A.S. and other 3rd party control solutions.
