The sat-nms ACU may be controlled remotely by a monitoring and control application either through the TCP/IP interface or through a serial RS232 interface (RS232 not yet implemented in ACU19 and ACU-RMU). Both communication methods use the same commands and parameters. However, there are different frames around each message depending communication method used.
Controlling the device from the web interface, the TCP/IP remote control interface or via the serial interface is completely equal, commands may sent to any interface at any time, the ACU will use the parameter it receives last.
