SonaFlex Technical Tips: Connecting Control Systems

Downloads

Note: IR controllers are adequate for many basic installations, but do not include many advanced commands.

 The SF-16M should be used with a professional automation control system. Its open-control architecture is designed for a third party automation controller to send serial or Ethernet commands to control volume, EQ, switching, overrides, sound scenes, and other functions, depending on the control system. SonaFlex provides seamless integration with Control4 systems, via SDDP.

SDDP is on by default. Use the Setup Utility to turn it on or off.

The front panel Network menu shows DHCP status and other network settings. Use the Setup Utility to alter the settings.
 
Using Serial and Ethernet 
Follow the instructions for the controller of your choice using the serial settings below, and/or IP settings accessible via the SF-16M front panel menu. Serial commands are used for IP or serial control. Control4 SDDP is enabled by default for seamless Ethernet integration.

Controlling Multiple Units - If you are unsing Ethernet to control multiple SF-16M units do not use the serial loop to connect them to each other. Serial feedback is not transmitted over Ethernet to the control device. 

Note: The internal SF-16M telnet server allows two clients to be connected at one time. Each client connection has a time out of 15 minutes; if a client crashes and does not close the connection properly (sending an EOF command) that connection remains busy until it times out.

There are two LED indicators located next to the Ethernet port on the rear panel that will help in identifying connection issues:
  • Link - The Link LED is steadily lit if a connection is detected and flashes when activity is present.
  • Speed - The Speed LED is off for 10 base T, and on for 100 base T.

Using the RS-232 Port for Serial Connection 
System controllers and PCs can send all setup and control commands as well as receive feedback via the RS-232 serial port. Important: If a PC is connected directly to the SF‑16M RS-232 port, use a standard serial serial cable (male to female) for RS-232 input, and to loop out to the next SF-16M, if multiple SF-16Ms are included in the system.

Using a PC via Ethernet
Connect a computer directly to the SF-16M Ethernet port using a crossover cable, or alternatively use a standard Ethernet hub or switch and a standard patch cable. Once connected to a computer or network, the SF-16M by default attempts to obtain an IP address automatically using DHCP. To use static settings, see these detailed instructions.

Using DHCP
DHCP is enabled on the SF-16M by default.  If DHCP is enabled on your network, simply connecting the SF-16M to the network with an existing DHCP server enables it to obtain all necessary information.  You can enter a static IP and turn DHCP off after initial setup is finished.
