Teledesign Systems Inc TS4000EH Manuel D’Utilisation

Power 

reflected (incoming) transmit power in 0.1 watt increments 
(i.e. 34 = 3.4 watts). 

This field is not available on all TS4000 models. 

A value of -1 (0xFFFF) indicates that this is not available 

from the TS4000. 

A value of -32768 (0x8000) indicates that there has not 

been a transmission since the last reset and therefore 
no measurement has been taken. 

Redundancy 

A one byte field indicating if the TS4000 is part of a 
redundancy switch setup. 

0 = Not in a redundancy switch 
1 = The TS4000 is the A modem in a redundancy switch 
2 = The TS4000 is the B modem in a redundancy switch 

Unused 

A nine byte field that is not currently used. 

Store and Forward 
Repeater List 

A ten byte field that is unused for local diagnostics. 

 
The remote diagnostics response is a total of 45 bytes with the following fields. 
 
Structure Field 

Header +TSDA 

This is a five character string in ASCII format. 

Local Address 

A five character string of numbers (most significant digit 
first) in ASCII format that indicates the address of the 
remote modem. 

The first two characters indicate the group address. 

The last three characters indicate the individual address. 

Diagnostic Version  A single binary character indicating the version of this 

structure. 

Reserved 

One byte – reserved for future use. 

Local RSSI 

A one byte binary number indicting the RSSI (Rx Signal 
Strength Indication) of the last message received.  

In units of –dBms (negative dBms)(i.e. a 87 = -87dBm).   

A lower number indicates a stronger receive signal. 

Repeater RSSI 

A one byte binary number indicting the RSSI (Rx Signal 
Strength Indication) of the returning request message at the 
first repeater that hears it.   

In units of –dBms (negative dBms)(i.e. a 87 = -87dBm).   

A lower number indicates a stronger receive signal. 

Remote RSSI 

A one byte binary number indicting the RSSI (Rx Signal 
Strength Indication) of the transmitted (outgoing) request 
message at the responding unit. 

In units of –dBms (negative dBms)(i.e. a 87 = -87dBm).   

A lower number indicates a stronger receive signal. 

Input Voltage 

A two byte (high byte first) binary number indicting the input 
voltage in 0.01 volt increments (i.e. 2432 = 24.32 volts).   

Note that this voltage is measured after a series diode and 
therefore is typically about 0.3 volts under the voltage at the
