LIFT COMMUNICATION · LIFT-SIDE CONNECTION
IP single-port
2/4-wire extension
4-group configuration
Connect to the duty side over the project IP network. This configuration has four intercom terminal groups in its product photo. Match wiring, intercom system and installation conditions to the actual unit.

Check intercom groups and communication separately
Organise intercoms and wiring by groups 1–4, then check the connection conditions for the single network port.
Intercom groups
Here, 4局 identifies the configuration with four intercom terminal groups. Check the intercoms, L/R/G/12V markings and 2-wire/4-wire version for each group.
Project network
Confirm access points, addressing and console communication. Distinguish visible interfaces from the functions available in the actual configuration.
