2.5 TSLM FIELD PROGRAMMING SOFTWARE
The TSLM Field Programming Software provides programming and diagnostics for the
Dataradio TSLM wireless modem. The Field Programming Software allows the user to edit and
program user programmable settings, interactively tune modem and RF parameters, and monitor
diagnostic data from the TSLM.
The PTT Watchdog allows the user to set the maximum transmit time. This is used to protect
against a ‘stuck’ transmitter. The time is selected by a slider bar. The range is 0 to 120 seconds
with a default of 30 seconds.
