Network Configuration – RS232 comms
The final section to setup is the network address. In all instances, this must be done before the controller is connected to the site network.
When logging a Mercury 3 with an RS232 interface onto a network you must first connect the controller to a communications module, this
is either a 485 Legacy, IP Futura, Mercury Switch or Wireless Mesh Interface. For Mercury 3’s with the IP interface please refer to the
Network Configuration – IP comms section for details of networking.
RS485 Legacy module
Using RS485, the controllers have an auto-initialise function, which will automatically log the device onto the site network. If the wrong
address has been entered onto the network, you will have to reset the controller address by setting the address to 00-0, and then re-enter
the correct address (you may have to deregister the wrong address from the home system as well).
Connecting an RS485 legacy Module to the controller will govern which set-up screens are made available in the ‘Net’ menu. The module
will support the “Genus” protocol only. Using RS485 will show the below;
Display
Option
485t
485 Network Type
485A
485 Address/ Name
gAdd
Show underlying network address assigned to controller
rLog
Re-log the controller back onto the network
ClrA
Clear the address/name from the controller
ESC
Exit network menu. N.B. this option must be selected to save any changes made in this menu
The 485t option shows a value representing the network type. The possible values are:
Value
Network Type
1
Genus compatible (all versions)
2
RDM Wireless Mesh System (Wireless Mesh)
Ensure option ‘1’ is selected (for RS485).
The 485A option shows a value representing the name of the controller in a Genus compatible network. For example, if the value shown
in 485A is shown as “05-6”. The controller would try to log onto a Genus compatible network using the name ‘RC05-6’.
The gAdd option displays (in hexadecimal format) the underlying network address assigned to the controller when it was logged onto the
network. Note: this is automatically assigned by the Data Manager.
The rLog option allows the controller to be logged back onto the network with its current name. The ‘rLog’ message will flash, waiting for
confirmation. To confirm, press the Enter button to execute the command, Up or Down buttons to cancel.
The CLrA option will clear out the network address and name in the controller. The ‘ClrA’ message will flash for confirmation. Press the
Enter button to execute the command, Up or Down buttons to cancel.
Fast Network Address Reset
To enter this mode, hold the Enter, Up and Down buttons together for approximately 3 seconds until the message CLrA appears on the
display. CLrA is the first option in the menu consisting of the following options:
Pressing the Enter button to select the CLrA option will cause the ‘CLrA’ message to flash for confirmation, if the network type is set to
Genus compatible. Press the Enter button to execute the command, Up or Down buttons to cancel. If the network type is not set to
Genus compatible then the ClrA message will not flash and the ESC option can be used to exit the menu.
Wireless Mesh Module
When a wireless mesh module is connected to the controller the ‘Net’ menu will show similar options to that off the ‘RS485’ network. The
only difference to the settings would be that the 485t should be set for ‘2’. Then the same steps should be taken to that of the RS485
option to log the unit on to the wireless mesh. Note, the wireless mesh network should already be set up on the data manager. Please
see the Data Manager documentation for setup instructions. Furthermore, please see documentation on the PR0730 Wireless Mesh
Network Module for setup instructions.
