TS4000 Radio Modem User’s Manual TS4000 Overview 6
The TS4000 has three LED indicators to provide operational status of transmit
(TX), receive (RX) and power (PWR) functions. Special combinations of these
indicators are used to indicate secondary operating modes and fault conditions.
TS4000 State LEDs Indicator State
Normal Operation PWR
RX
TX
On when the TS4000 is powered.
On when the TS4000 detects activity on the
radio channel.
On when the TS4000 is transmitting.
Program Mode RX, TX Both on continuously.
Reset RX, TX Flash together four times.
Although the reset indication takes about
four seconds to complete, the TS4000 is
fully operational when the flashing
begins.
Transmit Test Mode TX Flashes for the duration of the test.
Invalid Frequency
Channel Fault
RX, TX Alternately flash.
This fault occurs if the TS4000 is set for
a channel that does not have a valid
frequency programmed.
Transmit Buffer
Overflow
TX Flashes ten times for each occurrence.
Receive Buffer
Overflow
RX Flashes ten times for each occurrence.
Diagnostics Fault PWR Flashes for the duration of the fault.
In this mode the TS4000 has detected a
fault but continues to operate. Operation
may be unreliable due to the fault.
The most common cause of this state is an
out of range power source. The source of
the fault can be diagnosed with the
configuration program (see TS4000
Configuration Program, Diagnostics).
Catastrophic Fault RX, TX Alternately flash until the fault is cleared and
the TS4000 is reset.
In this mode the TS4000 has detected a
catastrophic fault and is non-operational
until the fault is corrected.
The source of the fault can be diagnosed
with the configuration program (see TS4000
Configuration Program, Diagnostics).
