This section describes the physical connections required to start
operating the Model 7150.
Figure 1: Model 7150 Rear Panel
The rear panel view of the switch is shown in the above figure. On the
rear of the switch are the following ports:
•POWER – Phoenix (F), External Power Supply Input connector.
•REMOTE – RJ45 (F), 10/100BASE-T LAN access Ethernet
Remote Control port.
•CASCADE:
oIN – RJ45 (F), the cascade port in from previous unit.
oOUT – RJ45 (F), the cascade port out to next unit.
•COM – RJ45 (F) connector, the “COMMON” or shared device
port, for each channel.
•A – RJ45 (F) connector, the “A” device port, for each channel
•B – RJ45 (F) connector, the “B” device port, for each channel.
Power Supply
After all the proper connections have been made, plug the Model 7150
into a 100VAC/240VAC, 50Hz/60Hz wall receptacle using the supplied
12VDC, 1500mA, UL listed and LPS approved, 2-prong US non-
polarized NEMA 1-15P plug wall mount power supply, P/N 517277.
Option: Wide Range Power Module, (Cat. No. 517277),
100VAC/240VAC, 50Hz/60Hz, IEC 60320 C14 inlet, can be ordered for

Upon power up the Model 7150 will process its power up routine. When
the routine is done the front panel LED's will indicate the present
position of the unit. At this point the unit is ready for operation.
Cascade Port Connections
These are custom RJ45 ports. There are signals present to support the
Cascade Operation feature that are not typically found on an Ethernet,
T1, E1, or any other standard that utilizes the RJ45 interface. Please
pay close attention to the connector pin/signal list and do not use this
port for other applications.
Please note that the maximum total bus length has only been tested to
200 feet. Exceeding this length may be possible, but it has not been
verified. Please also note that there should be one Cascade In/Out port
open on the unit at one end of the bus, and there should also be one
Cascade In/Out port open on the unit at the other end of the bus—do
not connect these end points directly together with another cable to form
a loop.
Note: Do NOT use a crossover cable as this will cause the unit to
malfunction and possibly cause permanent damage to the units.

OPERATION
The Model 7150 can be operated by the front panel, through its Remote
port, or through another unit connected to its Cascade ports.
Figure 2: Model 7150 Front Panel
Manual Control
The front panel view of the Switch System is shown in the above figure.
On the front of the switch are the following controls and indicators:
•A, B Indicators – Red LED’s indicate the position of the unit.
oThe LED indicates the position of the switch.
oIf the front panel control is locked and any pushbutton
is pressed, both position LED’s will light until the
pushbutton is released.
oDuring the power up routine, the LED’s will cycle
incrementally. This will continue for approximately 5
seconds (10 seconds when the Remote Ethernet
Reset has been initiated). Upon completion, the
LED’s will display the present position and be ready
for operation.
•A, B Pushbuttons – The position front panel pushbuttons allow
the switch position to be changed.
oDepressing and releasing the pushbutton for a
position allows the user to switch the unit to that
position.
oDepressing and holding a pushbutton for a period of
10 seconds will toggle the Mode of Operation. The
user must release the pushbutton before another
toggle of the Mode of Operation occurs again.
oWhen in a Group, pressing and releasing the
pushbutton for a position switches all connected
channels in this Group to that position.

oHolding any pushbutton on power up will initiate the
Remote Ethernet Reset routine.
oPushbutton control can be inhibited if locked out
remotely.
•Mode Indicator – Green LED’s indicate the state of the
Fallback Mode.
oThe LED indicates the Mode of the channel.
oIf the front panel control is locked and any pushbutton
is pressed, both Mode LED’s will light until the
pushbutton is released.
oDuring the power up routine, the LED’s will cycle
incrementally. This will continue for approximately 5
seconds (10 seconds when the Remote Ethernet
Reset has been initiated). Upon completion, the
LED’s will display the present position and mode, and
be ready for operation.
Automatic Fallback Mode
In Automatic Fallback Mode, the front panel AUTO LED of a channel is
illuminated. In this mode, the unit operates automatically by the signal
presence of the TD pin of port A. The TD pin (RJ45 pin 6) is monitored
for serial data activity with respect to the signal ground pin (RJ45 pin 4).
If the channel is in position A, the signal will be monitored for a loss in
signal for a selectable timeout period. The selectable timeout period for
each individual channel are as follows:
30 (factory default), 60, 90, and 300 seconds
A channel’s signal needs to be completely lost during the entire timeout
period for the channel to fallback to position B. If a signal is present
during the timeout period, the counter will restart and continue counting
immediately.
Upon the selectable timeout period for a channel being completed
without any serial data activity, the unit will automatically change its
position to position B. The channel will then remain in position B until
the user manually switches the channel back to position A via either the
front panel pushbutton or the Remote.
When in Automatic Fallback Mode and the position A, position changes
attempted by the front panel pushbutton will be ignored. In order to
change the position by the pushbutton, the channel must be changed to
Manual Mode by depressing and holding the front panel pushbutton for
10 seconds or through the Remote Graphical User Interface.
The channel can be changed into Manual Mode by depressing and
holding the channels pushbutton for 10 seconds.

Leader and Follower Mode
In Automatic Fallback Mode, there are two states a channel can be in
that changes the functionality of that channel’s signal.
In Leader Mode, the channel will have full functionality of the Automatic
Fallback Mode. The unit will monitor that channels serial data signal
presence and change its position accordingly. If the channel is a part of
a group, and a fallback change occurs to the channel in Leader Mode,
the unit will change all other channels a part of that group to the same
position, as well as, send a cascade command to other channels a part
of the group and in the same chain.
In Follower Mode, the channel will not have full functionality of the
Automatic Fallback Mode. The unit will not monitor that channels serial
data signal presence. This channel will only automatically fallback if a
channel in the same group is a Leader and that channels signal is lost
for its timeout period.
In Manual Mode, the Leader and Follower Mode do not change the
functionality of the channel but will remember this mode when the
channel is switched back to Automatic Fallback Mode.
Manual Mode
In Manual Mode, the front panel MANUAL LED of a channel is
illuminated. In this mode, the unit will not monitor the presence or
absence of the serial data signal.
When in Manual Mode, position can be toggled by depressing and
releasing the positional pushbutton.
The channel can be changed into Automatic Fallback Mode by
depressing and holding the channel’s pushbutton for 10 seconds.
Upon the change to Automatic Fallback Mode, the channel will stay in
its present position. If the channel is in position A, the unit will
immediately start monitoring the serial data signal on port A. See
Automatic Fallback Mode section above.

Group Cascade Operation
Group Cascade operation allows units and channels to be operated
together as a single entity. Units connected together via the Cascade In
and Cascade Out ports can be commanded to switch together from any
unit in the cascade.
Group Cascade operations are blocking of the Remote port—no other
Remote operations will be performed while Cascade Communications
happen in the background. If scripting commands at all, it is important
to look for these responses to confirm that the operations have finished,
avoiding flooding the input buffer and dropping commands.
NOTE: Cascade operation is only supported, if there is only one unit in
the Cascade whose Remote port is being used at any given time. It is
NOT supported to access multiple units’ remote ports simultaneously.
Operation in the case of multiple access is NOT GUARANTEED.
NOTE: Cascade operation is only supported for a maximum of 12 units
chained together. Operation in the case of additional units is NOT
GUARANTEED.
Definitions
A chain is a single consecutive series of units connected via the
Cascade In and Cascade Out ports.
A group consists of all units as part of a single chain, that are powered
and have channels in a specific Group.
Setup and Operation
Connecting Cascade ports requires a straight thru RJ45 cable. A
standard Ethernet cable will be sufficient. It does not need to pass any
Cat rating, but it is recommended to use cables that pass at least Cat5e.
To create a chain, connect units together by their cascade ports. The
Cascade In port of one unit must be connected to the Cascade Out of
the next. While connecting units in a chain, be sure that their channels
are not in a Group. This will create unity when adding channels to a
Group once all units have been connected together.
To create a group, units in the same chain must have channels in the
same group and powered.
Group State Synchronization
When in Group Mode, units in the group will stay synchronized in the
same position, mode, and lockout state. Commanding a position,
lockout state, or mode change on any channel in the group, whether by
pushbutton, remote, or automatic fallback, will command all channels in
that group to change to that position, lockout state, or mode. Units in

www.electrostandards.com - pg 14 - Pub. 6026-02
the middle of a cascade that are not powered or not part of a group but
are in the chain will still pass the cascade communications due to the
bus topology. Cascade communications may sometimes require a
second or two if there is another operation already taking place, or if a
higher priority operation is issued at the same time by another unit.
The unit handles and responds to any events that may alter the group,
including:
•Enabling Group Mode: If an individual channel is put into Group
Mode, it will assume the position, lockout state, and mode of the
existing group, if any, and switch automatically if necessary. If
the unit does not have channels in the new group or have not
processed any change commands for that group during the
unit’s present power state, it will put the channel in the factory
default settings of position A, unlocked lockout state, and
Automatic Fallback Mode.
•Disabling Group Mode: If an individual channel is taken out of a
Group, it will stay in the present position, lockout state, and
mode.
•Power Up: When a unit powers up, the position, lockout state,
and mode of all channels will remain the same as when it
powered down. If the unit has channels in a group, it will set the
states of position, lockout state, and mode to the current state.
If the unit does not have channels in a group, the position,
lockout state, and mode will be defaulted to factory defaults of
position A, unlocked lockout state, and Automatic Fallback
Mode. It will keep these group states until it processes a group
command through the Remote or a Cascade command from
other units through the chain.
Switch Position on Power Down
If power to the Model 7150 is lost, the switch will maintain its present
position and continue to pass data. Upon power restore, the unit will
assume the last position to which it was commanded before power was
lost.

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 the .NET Framework is not already installed, it must first be
installed. 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
If the desired device is not found in the list at all, the unit may have been
previously set with a static IP address that is not compatible with the
current network’s subnet and configuration. In this case, it may be
necessary to reset the IP address. See section “Resetting the Remote
Ethernet Port” on page 18.

CASCADE
Electro Standards Laboratories, Inc. [phone]
www.electrostandards.com - pg 17 - Pub. 6026-02
If use of the DeviceInstaller software is not something that can be done
in a particular circumstance, please consult Electro Standards for
specialized and tailored instructions on finding the unit on the network.
Unreachable Status in Red
If the desired device shows up in red and says “Unreachable”, typically
with an IP address that starts with “169” as the first octet, then the IP
Address will need to be reconfigured (see Figure 6). Alternatively, the
unit can be power cycled while the unit’s remote port is connected to the
network.
The reason for the “Unreachable” status has to do with a failure to
obtain an IP address through DHCP. When a unit is configured for
DHCP, upon power up, it will spend a certain period of time (typically a
few minutes) attempting to obtain an IP address from a DHCP server. If
no server can be found, the unit will assign itself an IP Address via its
AutoIP protocol. This AutoIP assignment is what allows the unit to still
be found via DeviceInstaller. It is strongly recommended to keep AutoIP
enabled if DHCP is in use.
Figure 6: Unreachable unit shown in red 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 DeviceInstaller software.After finding the unit in
DeviceInstaller, regardless of whether it is unreachable or not, select the
desired item in the list in the right pane. Click the “Assign IP” button
along the top menu bar (see Figure 5 or Figure 6). Follow the prompts
shown either to assign a static IP or to set the unit to DHCP.
Note that if the unit was unreachable and DHCP operation is desired,
the unit can be re-assigned to DHCP to force the unit to search for a
DHCP server again and obtain an IP address.
Setting a static IP address does override both DHCP and AutoIP,
meaning that the unit will always come up with that static IP address.
Note that this may cause conflicts if another device on the network is

using the same IP address, as the unit will not change its IP address
automatically.
Resetting the Remote Ethernet Port
The Remote Ethernet port can be reset to factory defaults. This is
especially useful in the event that an invalid IP address configuration is
set and the unit becomes inaccessible through the Remote Ethernet
port. To reset the IP address settings and any security settings (such
as password protection on the Telnet Configuration port), the following
steps must be performed:
•Power down the unit.
•While holding any front panel pushbutton, power the unit back
up. The pushbutton can be released once any of the LED’s on
the front panel light up.
•The unit will run through its reset routine. While this is
occurring, all LED’s will flash sporadically until it has finished.
The entire process will take about 18 seconds.
•Once the reset routine is complete, the unit will be ready for
operation without any further power cycling. It may be a few
additional moments before the Remote Ethernet port is
accessible while the unit acquires an IP address.
