Section 4. Control via the console port
The front panel of the multiplexer is equipped with a DB9 connector (female) with a RS-
232 interface, for connecting a control terminal (console). The console may be used to
view current device modes, link states, local and remote error statistics, to select device
modes and save them in non-volatile memory. For the console, the data rate is equal to
9,600 bits/s, 8 bits per character, no parity, 1 stop bit.
!
When the terminal is connected, the RTS signal (for stream control) must be
provided.
4.1. Upper level menu
The console interface is designed as a simple hierarchical menu. To select a command,
you must enter its number. To return to the upper-level menu, you must press <Enter> (or
<Return>). An example of the main menu is given in the picture:
