13.4.2 Supervision
Supervision of B308 Octo-output Modules on the
SDI2 bus is enabled automatically when the Relay
Destination of an off-board relay is set to Octo-
output. Each Octo-output module supports a
fixed range of off-board relays. Refer to Table 25
on page 71 for relay to module assignments. Any
failure to receive an expected response from an
SDI2 module results in a system fault display on
all keypads and a module specific SDI FAULT
event sent to the central station.
13.5 B420 Ethernet Communication
Module
The Bosch Security Systems, Inc. B420 Ethernet
Communication Module is a four-wire powered
SDI2 device that provides connection for two-way
communication over Ethernet networks to the
control panels. You can add up to two B420
Ethernet Communication Modules.
13.5.1 Address and Emulation Settings
The B420 address switches provide a single-digit
setting for the module’s address. The
module uses addresses 0 through 9. Refer to
Figure 30 on page 71.
Figure 30: B420 Switch Set to Address 1
The B420 has specific rotary switch settings for
SDI Addresses 88 and 92 or SDI2 Addresses 1
and 2 when used to communicate with Remote
Programming Software (RPS) or with a central
station network receiver. Refer to Table 26 for the
correct switch settings.
When the Reset Pin (labeled S1) is closed, all SDI
communication module addresses are
automatically enabled for RPS communication
without restriction.

13.5.2 Supervision
Supervision of Ethernet Communication Modules
at SDI2 Addresses 1 and 2 are enabled
automatically when used to communicate with a
central station network receiver. Supervision
ensures reliable operation between the module
and the control panel.
If supervised and the module does not respond
to control panel supervision polls, then a system
fault message appears at the keypads. A
corresponding report is sent to the central
station.
13.5.2 Local RPS Programming
Use the B420’s IP Direct connect feature to
locally connect with RPS. This connection
method requires a direct IP connection from the
