SHAPING THE FUTURE OF SATELLITE COMMUNICATIONS
5.4.3 Serial Interface and Port Settings
The main line settings for this serial interface are:
• Asynchronous data transfer;
• 1 start bit (logic “0”);
• 7 data bits (LSB first on line);
• Even parity;
• 1 stop bit (logic “1”);
• 4800, 9600, 19200, 38400, 57600 or 115200 baud.
To set the serial baud rate choose:
Elevation >> Unit >> Setup >> Serial port settings.
There is no flow control on the serial interface. Apart from correctly formatted
messages, the only significant character here is the SYNC-character (value 16
hex.). The device sends this character to indicate that it is busy executing the
command and preparing the response. This prevents other devices from taking
control of the bus if the response cannot be given immediately.
5.5 Protocols Used to Monitor and Control the Device
There are two protocols that can be used to manage your device:
• Remote Monitor and Control Protocol (RMCP);
• Simple Network Management Protocol (SNMP).
5.5.1 Remote Monitor and Control Protocol (RMCP)
This is possible via the serial interface (RS232/485) or over Ethernet.
The commands are described in the Reference Manual of your device.
The RMCP Manual explains how Newtec devices can be remotely
monitored and controlled via the serial port or via Ethernet.
This manual is delivered on CD-ROM together with the device.
