4092A Operations and Maintenance Manual 3
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.
Figure 1 shows the 4092A’s front panel, and Figure 2 shows the 4092A’s rear panel.

INPUT SELECT–Lit LED shows active
input. Use toggle switch to select active
input and set autoswitch mode.
INPUT–Green when connected to
input and receiving a signal. Red when
not receiving an input signal.
OUTPUT STATUS–Green during normal
operation of output signals. All red when
unit has no input signal on the active
channel.
POWER–Green when power is
on. One unlit LED shows unit has
one power supply. Red shows a
power supply failure.
