Before you enroll the Mercury controller on the Synergis™ Cloud Link
unit, you must assign a static IP address to the controller.
Before you begin
Make sure you have the following:
Mercury Setup and Configuration Guide
Instruction manual for connecting to the web portal of your Mercury controller and
setting up its IP address (and other configurations).
Static IP address
Static IP address assigned to the controller by your IT department.
Physical addresses
Each interface panel attached to the same RS-485 port of the same Mercury controller
must have a unique physical address (configured on a DIP switch).
Best Practice:
If you have many Mercury controllers to enroll on the same Synergis Cloud Link unit, it is best to enroll them all at the same time. Each
controller you add or remove from the Synergis Cloud Link unit causes the unit
to restart. While the unit restarts, it’s offline for about 30 seconds.
What you should know
Mercury controllers enrolled on the same Synergis Cloud Link unit cannot
be assigned different partitions in Security Center. If you need to assign the controllers to
different partitions, enroll them on different Synergis Cloud Link units, and
then assign the Synergis Cloud Link units to different partitions.
Note:
The steps and instructions tagged with Hardening are
optional, but will protect your system against cyberattacks.
Procedure
On the Mercury controller board, set the DIP switch S1-1 to
ON.
This gives you a five-minute window to sign in using factory default settings.
Sign in to the Mercury controller through its Configuration
Manager web page. Use the default IP address (192.168.0.251)
and credentials (admin/password). For more information, see the
manufacturer’s documentation.
Select Network from the menu, configure the Mercury controller’s
IP address, and click Accept.
Select Host Comm from the menu.
In the Host Communication page, configure the following settings,
and click Accept.
Communication Address
Set to 0.
Important:
Not to be confused with the
Channel that must be unique when you enroll the Mercury
controller on the Synergis Cloud Link unit.
Port Number
The port number used by the Synergis Cloud Link unit to communicate
with the Mercury controller (default=3001).
Authorized IP Address Required
(Hardening) Select this option, and set Authorized IP
address to the IP address of the Synergis Cloud Link
unit.
Data Security
Set to TLS Required.
Important:
If TLS is not
selected, the Mercury controller stays offline.
Select Users from the menu, and click New
User.
Creating a user account on the Mercury controller saves you from having to physically
access the unit and set the DIP switch S1-1 to ON the next
time you modify the controller configuration.
(Hardening) On the User Account page, enter the
Username and a strong Password, confirm
the password, and then click Save.
On the Users page, disable Time
Server.
The Time Server is not required. Synergis™ Softwire monitors
and automatically sets the time on the Mercury units.
(Hardening) On the Users page, disable SNMP
Options, and click Submit.
Select Apply Settings and click Apply Settings,
Reboot.
On the Mercury controller board, set the DIP switch S1-1 to
OFF for normal operation.
This prevents the factory default settings from being used to sign in to the
controller.
When prompted to proceed, select I understand and wish to
proceed, and then click Yes.
