You can also use a standard SSH client to access the Serial Access Unit options if
you don’t want to use 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 ServSwitch unit’s IP address using
port 22 (default).
Log into the SSH session as
admin
using the same password as the Web interface.
At the command prompt, type
connect x
(where
x
is the Serial Access Unit’s
device number). Or, you can enter
command connect -l
to see a list of active
devices.

• Hardware handshaking (CTS/RTS) is required for speeds exceeding 9600 bps.
It is enabled by default on the ServSwitch but may need to be enabled on the
other end of the connection. For UNIX systems, the command is:
stty -crtscts < /dev/[serial port]
• Serial Access Units use a simple RS-485 multidrop network running at
115,200 bps. Every Serial Access Unit will not be inputting/outputting data at
the same rate at all times. 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 individual channels’ output rates.
• Up to four users may simultaneously log into the same device. All users may
type commands at any time, and all users will see the same output.
NOTE
All users have equal access to all channels.
Up to 16 Serial Access Units can be connected at any time.
Plug in and unplug any Serial Access Unit at any time. When reconnected, it will
automatically become available after a 15-second initialization period. The Serial
Access Unit will retain any log entries while deactivated, but it will not be available
to users until you reinitialize it.
