ADJUSTMENT:
7=-,
8=+
Access to the menu MODEM CUSTOMIZING, requires the code 436215 and then keys 7 and 4. The code is not
required for 2 minutes after its first previous entry.
Keys 7 and 8 are used to reduce or increase the control value for modem operation, the range is from 0 to 5 and
0 is default value.
Value 0 =
the pin n. 20 of RS232 connector is set to low level (-12V) to inhibit the operation of a connected
modem.
NOTE: when a remote control panel is connected to the RS232 connector, instead of a modem, the value
MUST BE SET to 0 otherwise the remote panel does not operate.
Value 1=
the pin n. 20 of RS232 connector is set to high level (+12V)
to enable the operation of answer for a
connected modem.
Value 2=
the pin n. 20 of RS232 connector is set to high level (+12V)
to enable the operation of answer and
automatic calling for a connected modem.
When the automatic calling is set, 30 seconds after all "INTERNAL FAULT" alarm the system gives to the
modem the command "ATD" followed by the memorized "Dial" number.
The modem must be previously set to recognize the "HAYES" command and to dial numbers with (pulses or
tones) as required by the used telephone line.
After the “ATD” and Dial number, the system send to the modem the memorized "Send" number and a copy of
the panel display with a=..... code and date/time.
For example, if Dial = 123456, Send = 456789, 30 seconds after starting of alarm "Internal Fault
5" the system
sends to modem:
ATD123456.
The system, after receiving the message "CONNECT" from modem, sends to the modem the message:
UPS 456789
INTERNAL FAULT
M100,
OUT=100%VA, BATT= 78%Ah,
5=On
a=00200300 1994-12-21, 13:24:28
The system sends also the sequence to close connection:
+++ ATH
As last the system put on low level the DTR signal for 0.5 sec.
In case of busy line or modem not giving the response "CONNECT", the system wait 5 minute than repeats
again the commands ATD...... in order to try another phone call.
The system continues to try calling every 5
minutes until it receives the response "CONNECT" from modem or the alarm condition disappears.
Value 3=
like value 2 with the automatic calling for any kind of alarm or fault.
Value 4=
like value 2 with the automatic calling only with alarm 10 (Internal Fault) but with sending of display
message only after received the character "}".
This operation can been used for avoiding the loss of a message, because the system sends its message only
after receiving the special character "}" that can send only by a computer.
