Teledesign Systems Inc TS4000GL Manuel D’Utilisation

The TS4000 has three lights (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 

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 between 6 and 16 times for each 
occurrence depending on the details of the 
overflow 

Receive Buffer 
Overflow 

RX 

Flashes between 6 and 16 times for each 
occurrence depending on the details of the 
overflow 

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).
