1.3 4092A Overview
The TSC 4092A IRIG-B Autosense Fault Switch is a 1U (1.75") high, 19-inch, rack-mount,
autosense, fault switch that accepts two IRIG-B inputs and produces eight outputs (chosen from
the two inputs). The unit can be configured with redundant hot swappable AC or DC power
supplies. The TSC 4092A can also be configured to accept two 1-200 kHz sinewave signals but
traditionally would be used as an IRIG-B Fault Switch.
The front panel provides green/red LED status for the inputs and for all output signals, as well as
indicating the active input signal. A green/red LED on the front panel also provides power status.
The front panel also has a locking toggle control switch that you can use to manually switch
between input signals or to configure the unit to switch automatically upon input signal failure.
An Ethernet port on the rear panel provides the capability to remotely monitor the status of the
power supplies, input, and all output signals. Any failure in the unit will immediately provide an
alarm to this port.

For information about configuring the network connection, see “2.3 Assigning a Static
IP Address” on page 6.
2.3 Assigning a St atic IP Address
The 4092A contains a Lantronix® Xport™ Ethernet to RS-232 converter, which provides the
4092A’s Ethernet connection.
The 4092A ships from the factory with a default IP address of 0.0.0.0, which enables DHCP. If the
network has a DHCP server, it will assign each unit an IP address, gateway address, and subnet
mask when the unit starts up.
6 2: Installing and Setting Up the 4092A
To monitor multiple 4092A units remotely through their Ethernet connections, you must assign
each unit a fixed IP address. You identify which unit is the source of an alarm by its IP address.
Follow the instructions in this section to assign a unit’s IP address.
Note
For more detailed information, see the Xport User Manual. Section 3.3 discusses several different
ways that you can assign IP addresses. Chapter 4 explains how to permanently configure the IP
address. You can download the Xport User Manual from the Lantronix® Web site as an Adobe®
Acrobat® PDF file. Go to:
http://www.lantronix.com/
If you want to permanently configure the IP address, you must install the Lantronix
DeviceInstaller software. This software is available only by downloading from the Lantronix Web
site. Go to: http://www.lantronix.com
You can also assign the IP address using Telnet.
Note
If you move the 4092A to a different network hub after setting up the static IP address, the host
computer may not be able to make a connection. You may need to release the IP address lease on
your operating system.
To assign the static IP address using the Lantronix DeviceInstaller software:
1. Obtain the following network information from your system administrator for each 4092A
you want to install:
IP Address: ______ ______ ______ ______
Subnet Mask: ______ ______ ______ ______
Gateway: ______ ______ ______ ______
2. Connect a Windows® PC to the same local subnet as the 4092A.
3. Install and start the Lantronix® DeviceInstaller software.
4. Click the Search Network icon and search for XPORT devices connected to the network,
then click Save and Exit.
5. Click the IP icon or select Assign IP Address on the Tools menu.
The hardware device number and IP address appear in the Assign IP Address dialog
box.
6. Type the new IP address and click OK.
The new IP address appears in the Lantronix DeviceInstaller window.
7. Test the IP address by pinging the 4092A’s Xport on the Lantronix Xport Installer
window.
Click the Ping icon or select Ping Device on the Tools menu.
The Ping Device window should show the IP address of the 4092A’s Xport device,
and it should show successful replies if the IP address has been configured correctly.
8. Exit the browser.

The system returns I4092A-00\r\n, where the 00 is the hardware version, and turns on
the front panel input LEDs for two seconds before returning to normal operation.
If you see these responses, you know you are communicating with the unit.
2.4 Selecting the Active Input Channel
You can select the active input channel using either the toggle switch on the front panel or
remotely using the Ethernet connection.
To select the active input channel from the front panel:
1. Move the toggle switch by pulling the switch out, then moving it to the channel you want
to use.
The LED for the selected channel should be solid green.
2. If you want the unit to automatically switch to the other input channel in the event of a
failure, move the toggle switch back to the center position.
This puts the unit into autoswitch mode.
To select the active input channel remotely:
1. Telnet to the 4092A’s IP address.
No prompt displays in the Telnet window.
2. Type either A or B, depending on which channel you want to select.
You do not need to type a carriage return or line feed.
The LED on the for the selected channel flashes green, showing that the channel has
been selected remotely. It continues to flash green until you select the channel using
the toggle switch on the front panel or set the unit to autoswitch mode.
3. If you want the unit to automatically switch to the other input channel in the event of a
failure, type: C
The LED for the selected channel changes to solid green, showing that the channel is

3: Monitoring the 4092A
3.1 Accessing the System
You access the 4092A system remotely by connecting to its Command-And-Response (CNR) Port
through the Ethernet connection. The CNR port (Port 10001), which uses TCP/IP, lets you input
commands, displays results of the commands, and publishes alarms as they occur.
When you Telnet to the CNR port, the system does not display a prompt.
3.2 Checking System Information
3.2.1 Checking Status and Alarms
The system can report status and alarms that occurred since the last status check.
To check system status:
Type: S
You do not need to type a carriage return or line feed.
The system returns Sabcde,fghij\r\n where
abcde is current status.
fghij is latched alarms and changed status since the last status request.
Both abcde and fghij are hexadecimal numbers, with each bit position representing one
output. LSB (farthest right) is output 1. MSB is the input. Bits 0–12 are latched alarms.
Bits 13–19 are change in status bits.
Latched alarms remain active in the current status field and latched status field until the
problem is corrected. Changed status bits are cleared upon next status request.
Example: S0A001,00001
This example shows that input B was selected using the front panel toggle switch, channel B is
active, and output 1 had a failure since the last status request.

• The system returns Vxx\r\n where xx is the software version.
Example: V00.
14 3: Monitoring the 4092A
3.3 Understanding Alarm Output
The 4092A automatically publishes alarms to the CNR port as they occur.
The alarms appear in the format ALARMfghij where fghij is the summary status of the input and
output signals. The format of the alarm status is identical to the “S” command response defined in
Table 1 on page 12.
Example: ALARM00003
This example shows that outputs 1 and 2 have active faults.
4092A Operations and Maintenance Manual 15
16 3: Monitoring the 4092A
4: T roubleshooting the 4092A
Perform all of the following procedures before returning the unit for service. If the unit still
appears to have a problem, call Timing Solutions Corporation and request technical support. Have
the serial number of your unit ready to give to a technical representative.
4.1 T roubleshooting Input Problems
As long as the 4092A is in autoswitch mode and has two valid input signals connected, the unit
will automatically switch to the other input channel if it stops receiving a valid signal on the active
channel.
If the unit loses the active input signal, the LED for the that input turns red until you correct the

low Z input and output impedance. If the signal sources have a high Z output impedance, then
Caution
When opening the top cover and changing the power supply settings, use proper ESD precautions.
This includes ensuring that you are properly grounded before touching the internal PWA of the
unit to change the jumper settings.
Required for this procedure:
#1 Phillips screwdriver
To change the jumper settings:
1. Disconnect both power supplies from their power source.
2. Using a #1 Phillips screwdriver, remove the top cover.
3. Move the jumper one position to the left to the 2S position.
4. Replace the top cover.
5. Reconnect the power supplies.

4.5 Configuring for Dual Power Supplies
The power supply setting is configured at the factory based upon single or dual power supply
configuration. If you are adding a second power supply to a unit that was originally configured for
a single power supply, you should change the internal jumper setting. The jumper setting ensures
that the power supply LEDs reflect the proper configuration and that the second power supply is
monitored.

2. Using a #1 Phillips screwdriver, remove the top cover.
3. Move the jumper one position to the left to the 2S position.
Power supply jumper configured for
one power supply (in the 1S position).
4. Replace the top cover.
5. Reconnect the power supplies.
4.6 Replacing Power Supplies
For units with a single power supply, the normal LED state is for one LED to be green and the
other not lit. For units with dual power supplies, the normal LED state is for both LEDs to be
green.
If a power supply LED is red, check that the affected power supply is connected to a properly
functioning 100–240 VAC, 50/60 Hz power source. If the LED remains red, you should replace
the power supply .
For AC power supplies, use only TSC 4501A power supplies. For DC power supplies, use only
TSC 4502A power supplies.
In a unit with dual power supplies, you can hot swap the power supplies. This means you can leave
the working power supply connected to power and all input and output devices connected when
you replace the failed power supply.

4. Slide the power supply out of the chassis.
5. Slide the new power supply into the chassis, making sure it clicks into place.
6. Replace the two screws in the power supply.
7. Replace the ground screw in the power supply.
8. Reconnect the power cord to the new power supply.
4.7 Replacing Fuses
If you know that a local event caused blown fuses throughout a rack, you can replace the fuses in
each 4501A power supply. The AC power supplies have two fuses.
The DC power supplies do not have any customer-serviceable fuses.
Required for this procedure:
Small flat-head screwdriver
