3.7 VCU Control via Serial Interface
The serial port located on the back of the Net-2000™-VCU unit provides the same control functions as the web
interface. The interface itself consists of a simple command/response ASCII text protocol. To access the interface
use a terminal or terminal emulator on a personal computer to type in commands.
All commands are ASCII character strings terminated by a newline character (ASCII 0x0A). The maximum size
allowed for a command is 512 characters. Commands are case-sensitive. Command arguments are separated by
white space. With the serial cable connected and the terminal running type a few carriage returns at the keyboard.
The Net-2000™-VCU responds with the console prompt as shown below:
