8.3 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 two modules.
The B426 Conettix Ethernet Communication Module connects to the SDI2 bus on the control
panel using terminals 27 through 30 (or 23 through 26 if configured for SDI2), 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: F01U281208).
8.3.1 Address and emulation settings
Notice!
The module reads the address switch setting only during module power up. If you change the
setting after you apply power to the module, you must cycle the power to the module in order
for the new setting to take effect.
Set the address switch to 1 or 2.
If multiple B426 modules reside on the same system, each B426 module must have a unique
address.
8.3.2 Supervision
The control panel supervises in two ways:
– Module supervision. The control panel supervises the module through polling. If the
module does not respond to the control panel polling, the control panel declares the
device missing.
– Communication supervision. The control panel supervises the communication path by
polling the central station receiver. If the poll is missed from either side, a communication
fault is declared both at the control panel and the central station receiver.
8.3.3 B426 module faults
With a B426 installed, several services become available to the control panel. Any break in the
Ethernet connection to a supervised B426 results in a system fault at the keypads indicating
Open Cable trouble.
If a Domain Name Server (DNS) is available on the network, a failure to resolve an individual
Network Address hostname results in a system fault at the keypads indicating DNS ERROR ##.
The error number represents the communication module and destination combination that
failed. Refer to RPS Help or the control panel’s Program Entry Guide for details on
communication module/destination combinations. The keypad shows a failure to resolve the
domain name used for RPS Network Address.
