Specifications

You are now connected to the Serial Supervisor device. Commands you type will be echoed on the

terminal screen. It offers a simple menu system that allows you to change its configuration settings.

To access the menu press Ctrl + Shift + Space (underscore) on the keyboard to access the

menu. It will be similar to the following:

RS-232 Menu (#1: (none), 115200 bps, 8N1)

Q – Disconnect

# - Send break

H – Hangup line (drop DCD)

E – Send Ctrl-Shift-_

L – Low log entries (line buffer)

1 – Show last 10 log entries

other – Return to connection

Press key ->

To execute the desired command, simply press the corresponding key on the keyboard. You can also

execute the command and avoid the menu by pressing the Ctrl + Shift + Space key combination

quickly and pressing the letter of the command. To quit the menu, press Q on the keyboard when

the menu is active.

Remote Login via SSH

You can also use a standard SSH client to access the Serial Supervisor options if you wish to avoid

using the Java-based SSH client in the Web interface. Simply use your SSH client (several freeware

packages are available for download, along with commercial applications) and connect to the IP

address of the Digital KVM via IP using port 22 (default).

command prompt type connect x (where x is the number of the Serial Supervisor device you wish to

manage). Alternatively, you can enter the command connect -l to see a list of active devices.

Operating Notes

y Hardware handshaking (CTS/RTS) is required for speeds exceeding 9600 bps. It is enabled by

default on the Digital KVM via IP, but may need to be enabled on the other end of the

connection. For Unix systems, the command is:

stty –crtscts < /dev/[serial port]

y Serial Supervisor devices use a simple RS-485 multidrop network running at 115,200 bps. It

is possible that every Serial Supervisor device will not be inputting/outputting data at the same

rate at all time. However, since these devices use interactive logins, it is unlikely that all

channels would be busy at any one time. Hardware handshaking is used to limit the output rate

of individual channels as needed.

y A maximum of four users may simultaneously login to the same device. All users may type

commands at any time, and all users will see the same output. Note the following:

y All users have equal access to all channels.

y A maximum of 16 Serial Supervisor devices may be connected at any one time.

 You plug-in and unplug any Serial Supervisor device at any time. When reconnected, it will

automatically become available after a 15 second initialization period. Any log entries will be

retained by the Serial Supervisor device while deactivated, but will not be available to users until

it is re-initialized.
