4.7 Encrypted Module Network
The Protégé® SE Integrated System Controller incorporates technically advanced encrypted RS-485
communicaons technology. The isolated communicaons interface oers full galvanic isolaon to
prevent ground loop noise and cross phase ground dierenal. The communicaon oers superior
interference immunity. Connecon of the communicaons should be performed according to the
following diagram.
