CONNECTED, are regarded as OPEN CIRCUIT and the corresponding
message "OPEN" will be displayed in the cell RES
- VSYS: this is the value, measured in volt, of the SYSTEM battery
(microcontroller, peripherals, radio) on the Remote Unit. The measurement is
made EACH TIME the Unit or a specific line is called. If the voltage of this
battery falls down a preset value, the error message "FAULT" will be
displayed. This message shouldn't regarded as a catastrophic failure on the
Remote Unit, but it is just a WARNING about the poor charge level of the
battery (a recharge is urgently needed!)
- VFIRE: this is the value, measured in volt, of the FIRING LINES
BATTERIES on the Remote Unit (2 batteries in series for 24V total). The
measurement is made EACH TIME the Unit or a specific line is called. If the
voltage of these batteries falls down a preset value, the error message
"FAULT" will be displayed. This message shouldn't regarded as a catastrophic
failure on the Remote Unit, but it is just a WARNING about the poor charge
level of the batteries (a recharge is urgently needed!).
- RSSI(unit): it represents the value, in dBµV, of the field strength present at
the receiving antenna on the Remote Unit. Practically: this reading gives an
idea of the quality of the radio reception on the Remote Unit during a request of
data. The measuring range is between 0 and 80dBµV (0dBµV = NO
SIGNAL, 80dBµV = MAXIMUM SIGNAL). When the reading is BELOW
20dBµV, some error in data reception could occur and it would be advisable
to check the antenna or Unit position (see specific notes to the relative
chapter) in order to improve the radio signal level. When the reading is down
to 12dBµV, the warning message "WEAK" is displayed.
- RSSI(main): it represents the value, in dBµV, of the field strength present
at the receiving antenna on the Base Unit. Practically: this reading gives an idea
of the quality of the radio reception on the Base Unit during the reception of
answer back from the Remote Unit. All other details are the same as in the
previous case.
The only data the operator can modify are: SEQ ("SEQUENCE") and TIME.
In order to modify these parameters, the keys F1 (SEQ), F2 (TIME), F3 (UP), F4
(DW - down) will be used. Eventually also F11 (Pgup) and F10 (PGdw) if the data
to be modified are not displayed in the actual page. In any case F3 and F4 keys,
provide to scroll automatically the displayed lines when the table limits are reached.
Using the above listed keys, it will be marked (in reverse) the parameter relative to
the specific line to be changed and the new value will be typed in directly using the
numeric keypad; ENTER will confirm the value and the new data will be
immediately sent to the Remote Unit and stored accordingly in memory.
All data relative to TIME can be also typed without the separators and disregarding
all non-significant zeroes. E.g.: the time value 00:17:12,35 (17 minutes, 12 seconds
and 35 hundredths) can be typed "171235" as well as "17.12.35" or "00.17.12.35" or
again as "00171235". It will be accepted in all cases.
