What can it do for me?

When you create an installation of an Impera Control System with web interface (E.g. Sierra II) and you’re using it in a network, there are some things you should keep in mind as the installer. The IT administrator in a company might want to know what consequences and security issues it could have to install a new network device.

What do you need to know?

When a control system is connected to a LAN network, several services starts and generates traffic on the network.

Background services

  • LAN lookup: On UDP port 8000 identification information is broadcasted when our configuration software Project Designer requests them. This information is only sent when maintenance is performed to the control systems.

  • Central Control Live updates: On UDP port 8001, the control system broadcasts its status

  • information each time one or more LED changes state.
  • Central Control draws service: on TCP port 5009, Biamp Central Control can actively connect to
  • the control system and get status and execute button press.
  • Extension device lookup: Every 3rd sec. a look-up/keep-alive status is transmitted using multicast address 224.10.10.25 port 7979.
  • The control system support IGMP, so by using a switch that supports IGMP you can make sure that data is only transmitted to the Biamp Control System and extension devices.
  • Upload/download of project: TCP port 23 (Telnet) and 20+21 (FTP). The mentioned ports are used when changing the configuration of the control system.
  • The ports should not be used for anything else than the Biamp configuration system.

Using a graphical interface

When adding a graphical interface to the control system, each graphical interface, which connects to a control system, will create a TCP connection on port 80 (HTTP). To make sure that this connection is always open, keep-alive data is transmitted back and forth every fifth sec.
Whenever the control system is used, the traffic between the graphical interfaces and the control
system increases on port 80.
