communications. For more information see alarm panel specific documentation available from AddSecure.
6.9.4.4 Serial settings
This option lets you modify the baud rate and parity of the connection.
Serial port RS485
The configuration setting for the RS485 serial port has these options:
Choose the one you need.
6.9.5.1 Galaxy
This sets the RS485 bus for Honeywell Galaxy mode where the terminal will
automatically emulate one of the galaxy communication modules in the
following order: Ethernet, PSTN, External RS232.
6.9.5.1.1 Galaxy Settings
This opens the Galaxy settings screen with two more configuration options:
System ID
This lets you enter a system ID independently from the panel that will override
the current ID sent by the panel.
To enter the ID, which will override the existing ID, click «clear», enter the ID,
then click «save».
Emulation mode
This option lets you select the Honeywell Galaxy RS485 bus communication
module emulated.
This provides backwards compatibility with older Galaxy panel software versions
that do not support the Honeywell Ethernet module (Galaxy Classic below
version 4.00).
The default is Auto (Automatically assigned). This will try the external Ethernet module first. If this is not
found, it will try the external PSTN, and finally the external serial modules.
You can also preset the emulated module to be Ethernet or PSTN by clicking the relevant box. This may be
needed if, for example, there is already a Honeywell Ethernet module fitted.
6.9.5.2 ProSYS
This sets the RS485 bus for the Risco ProSYS bus to allow Upload/Download connections but not alarms. For
this to be useable for alarm transmission from the panel, the panel alarm must be connected to the dial port,
or to the "pin input" signals.
6.9.5.3 ESMI
This option displays the "ESMI Settings" submenu where you can change settings for ESMI Fire Panel serial
interfaces on the RS485 port.
