2) The Remote Unit selected "answers back" and the data will be printed on the
LCD screen. In the example below: the selected line is NOT connected or the
line resistance is greater than 99 ohm and the sequence of that line is of "no
timed" type. The data will be displayed as follows:
The indication "OPEN" in the cell "RESISTANCE" just warns as the line
resistance is greater than 99 ohm (too high to grant a safe firing with a 24V
line voltage) or the line is OPEN.
The "TIME" value is not shown because the sequence 237 for line 25 of the
Remote Unit N°2, is not a timed one.
RSSI Main shows a 58dBµV value. This parameter represents the field
intensity (at the antenna of the TX2000 Unit) of the radio signal received
from the Remote Unit. The measuring range spans from 0 to 80dBµV. When
the signal goes down to 20dBµV, the "WARNING" icon appears: the signal
is too low and some communication error could be encountered.
RSSI Unit shows a value of 67dBµV. This parameter represents the field
intensity (at the antenna of the Remote Unit RX24-B) of the radio signal
received from the Base Unit during the DATA REQUEST of the TX2000.
The measuring range and the details about the signal level are the same as for
the previous example.
SYSTEM shows a value of 12. 6V. This is the voltage of the battery
powering the whole SYSTEM (radio, microcontroller, peripherals, etc.) of the
Remote Unit checked. Should this voltage drop below 11.6V, the
"WARNING" icon will be displayed because the correct voltage level to the
system circuits could be no longer granted.
FIRE shows a value of 25.1V. This is the voltage of the batteries powering
the firing lines of the Remote Unit checked. Also in this case, should the
value drop below 23V, The "WARNING" icon will be displayed because the
necessary power level could be no longer available for the firing lines.
