CLI Management Interface
CLI Access via the RS232 Serial Port
To use the CLI management on the VPG you must connect to the RS-232 external management serial port (P3)
or through the backplane serial port connection. Only TX, RX and GND connections are needed for operation.
You then must open the serial port in a terminal program such as: RealTerm, Putty, HyperTerminal, minicom,
etc. The COM port must be set up to run with a baud rate of
115200, 8 data bits, 1 stop bit and no parity
.
Note: the VPG external serial port is compatible with RS-232 Input/Output Levels (NOT TTL or CMOS).
