Remote Control Commands
All commands are ASCII commands. For Control Commands, the
command is created by pressing and holding the [CTRL] key and the
designated character key simultaneously. For example, to create the
CTRL-A command, simply press the [CTRL] and [A] keys on the
keyboard simultaneously then release both.
When starting an SSH session, the user will be prompted to enter a
username and password. The default username is “admin” and the
default password for this user is “ESL02921”.
Once the Model 7183 Remote SSH session has been initiated,
commands from Table 2 can be entered. Do not press the enter key at
the end of a command. All responses are terminated with a carriage
return (‘\r’) followed by a new line feed (‘\n’).
A note to those programming their own systems to control this switch
automatically: The ASCII Control Commands are represented as the
decimal equivalent of the numerical position of that letter in the
alphabet, which can then be translated to hex. For example, CTRL-A
translates to ‘1’ in decimal or 0x01 in hex, since A is the 1st letter of the
alphabet. CTRL-V, on the other hand, translates to ‘22’ in decimal, and
0x16 in hex, since it is the 22nd letter of the alphabet.

Error conditions not covered in Table 2:
•
Issuing a command not found in Table 2 will respond with the
error message: “Invalid Command.” and no switching will occur.
Whenever a front panel pushbutton operation takes place, the new
status will automatically be sent to the SSH session when logged in.
When the unit sends automatic updates, they will be in the same format
as the response for the CTRL-P command.
Switch Position on Power Down
If power to the Model 7183 is lost, the switch will maintain its present
position and continue to pass data. Upon power restore, the unit will
remain in the position it was in at power down.

REMOTE ETHERNET CONNECTIONS
Verify the Hardware
Verify that the switch is currently powered. If the user needs to directly
connect to the switch rather than through a LAN, a 10/100BASE-T
crossover cable will be necessary (ESL can provide this – p/n 984228-
006). This cable allows direct connection of the switch’s Remote LAN
port to a computer with a Network Interface Card (NIC).
If no LAN is available, use a Crossover Cable
If no LAN connection is available, the user can use a crossover cable.
Plug one end of the cable into the RJ45 Remote port on the rear of the
switch and the other end into the computer NIC as in Figure 3.
Figure 3: Crossover Cable connection for no LAN
If connecting to a LAN use a 10/100Base-T Cable
Use a straight through 10/100BASE-T patchcord from the switch’s LAN
Remote port to a LAN connection, and likewise, reconnect the computer
used to configure the system via a standard, straight through patchcord
to the LAN as in Figure 4. ESL can provide this cable (p/n 984231-006).

10/100BASE-T LAN SETUP
Network Setup
The switch is configured from the factory to use DHCP to automatically
get its IP address from a DHCP server on the local area network when
connected to the network and powered up. Therefore, a DHCP server is
needed on the local area network for the initial configuration. After that
the switch can be configured to use a static IP address. To find the IP
address of a switch that it has gotten from the DHCP server or to
reconfigure the IP Address of the switch, use the Lantronix®
DeviceInstaller application.
Getting DeviceInstaller
DeviceInstaller requires Microsoft's .NET Framework version 4.0 or
higher. If you do not already have .NET Framework installed, you must
first install it. The .NET Framework can be downloaded from Microsoft’s
website, either as a web install, or as a standalone installation. The
latest version of DeviceInstaller can be downloaded from Lantronix’s
website.
Finding the IP Address of the Switch
After installing DeviceInstaller and opening it, the software will
automatically search for devices on the network. Once found, the
devices will be listed in the right pane (see Figure 5). Match the MAC
address on the rear of the unit to the MAC address (“Hardware
Address”) shown in DeviceInstaller to correctly identify the desired unit
and find the associated IP address.
Figure 5: Finding the IP address in DeviceInstaller
Static/DHCP IP Address Configuration
The switch can be configured to use a static IP address or DHCP. This
is done through the Remote Configuration GUI. See section “IP
Address/Network Configuration” on page 17.
