Control String 

+TSDL 

Request diagnostics from the local modem. 

+TSDAggiii 

Request remote diagnostics from the modem with address 
ggiii. 

gg = Group address as ASCII characters 

iii = Individual address as ASCII character 

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

Header +TSDL 

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 local 
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 field that is unused for local diagnostics. 

Remote RSSI 

A one byte field that is unused for local diagnostics. 

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 
power leads. 

Radio Voltage 

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

Temperature 

A two byte (high byte first) binary number indicting the 
internal temperature in degrees Celsius 

RF Forward Power  A two byte (high byte first) binary number indicting the 

forward (outgoing) 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. 

RF Reflected 

A two byte (high byte first) binary number indicting the
