B426 Ethernet Communication Module
The B426 Conettix Ethernet Communication Module is a four-wire powered SDI2 device that
provides connection for two-way communication over Ethernet networks to the control panels.
The control panel supports one module.
The B426 Conettix Ethernet Communication Module connects to the SDI2 bus on the control
panel using terminals PWR, A, B, and COM, or using the SDI2 interconnect wiring connector.
This section includes basic installation instructions. For detailed installation instructions, refer
to the Conettix Ethernet Communication Module (B426) Installation and Operation Guide (P/N:
