Link Establishment and BER Testing
The primary function of the TSLM is to transmit data created by the DTE or application
software. CalAmp DataCom modems and modulation types typically permit an overall raw
error rate of better than 1 error in 10
-6
as long as signal strengths are adequate. Depending
on the speed and the radio being used this error rate can be obtained with signal levels of
approximately -107 dBm, but be sure to allow a sufficient signal fade margin.
Using a Dataradio TSLM at 9600 bits per second transmission, an error rate of 1 in 10
-6
means that you can expect 1 bit error every 107 seconds (in use, errors will likely be much
less frequent, but consider designing for the worst case).

Online diagnostics
Online diagnostics provide three types of information:
Supply voltage
Internal temperature
Received signal strength (in dBm) (RSSI)
