TS4000 Radio Modem User’s Manual Appendix E – Control and Status Strings 87
Structure Field Description
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 Description
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
