TS4000 Radio Modem User’s Manual Appendix E – Control and Status Strings 86
Control String Description
+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 Description
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
