Display Terminal Unit programs the telephone number to be
dialed The Keypad can also be used to program the phone
number to be dialed by the Auto-Dialer Unit The Terminal
Unit can request for the history of events during which the
COP888CG reads the NM93C06A Please refer to the appli-
cation note on MICROWIREPLUS for details regarding the
interface between COP888CG and NMC9306
Display Terminal Interface Routine
The Display Terminal as previously mentioned interfaces
with the COP888CG through the full-duplex double buffered
UART The terminal is used to display the history of events
real time and sequence of operations upon detection of
signal by the Receiver Unit
The request for display of events and programming the
phone number interrupts the COP888CG However the
Time Keeping Routine updates the LED display and termi-
nal with real time periodically except when the COP888CG
is servicing the Receiver Unit
The operation mode of the UART may be selected in con-
junction with both a prescaler and baud rate register Char-
acter data lengths of seven eight or nine bits are program
selectable in conjunction with a start bit an optional parity
bit and stop bits of
1 1and
or 2 The UART also
contains a full set of error detection circuitry and a diagnos-
tic test capability as well as an ATTENTION mode to facili-
tate networking with other processors
Please refer to the Users Manual or Microcontroller Data-
book for details
In the ASM System the COP888CG interfaces with the V550
terminal at 2400 baud 8 data bits 1 Stop bit no parity The
receiver buffer full and transmit buffer empty generates an
interrupt The Port L (pins L1 L2 L3) are used for the UART
interface as CKX (clock) TDX (transmit) and RDX (receive)
respectively
The display terminal is used to display time both in analog
and digital form The V550 allows interfacing both in alpha-
numeric and graphic modes with separate memory for each
of the modes The COP888CG is programmed to send out
the ASCII ESC sequence required to generate the graphics
on the screen
Auto-Dialing Routine
This routine is responsible for dialing the number in the
event of an emergency The COP888CG interfaces with
TP5088
which in turn interfaces with TP5700A
The
COP888CG activates the relay that keeps the telephone
line on-hook to the off-hook position After this it times out
to get the dial tone After a fixed amount of time the digit to
be dialed is sent out on the D port lines D1 – D4 to TP5088
along with the Chip Select The TP5088 generates the
DTMF signal for the digit The COP888CG takes care of the
timing required between two digits and also the on-time of
the DTMF signal for each digit The output of the DTMF
signal goes to the TP5700A which interfaces with the Tip
and Ring of the telephone lines The TP5700A receives the
signal from the telephone lines and LM567 along with the
associated circuitry is used to detect whether the required
frequency signal was sent by the unit responding to the tele-
phone The output of the LM567 is connected to Port I pin 5
The Receiver Routine polls the Port I pin 5 periodically to
check for response from the unit dialed by the Auto-Dialer
Unit
Receiver Routine
This is the main interrupt service routine of the ASM Sys-
tem The Receiver Unit interfaces with the COP888CG
through the L port pin 4 Upon receipt of the signal from the
Sensors and Transmitter Unit the Receiver Unit activates a
relay which causes a MIWUInterrupt The interrupt service
routine then waits for 10 seconds before reacting to the
signal This time is allowed to disarm the SecurityMonitor-
ing System The Time Keeping Routine is used to caculate
the delay and if the user disarms the System by toggling a
switch the signal is ignored Otherwide the Non-Volatile
Storage Routine is executed to read the telephone number
and this information is passed on to the Auto-Dialer Unit
The Auto-Dialer Unit dials the number and looks for a re-
sponse over the telephone line If however there is no re-
sponse the Receiver Routine times out after a minute and
tries the same number again The number of trials can be
modified in software and the time out period can also be
changed In the ASM System the number of trials is two
With slight modification the Auto-Dialer Unit can be made to
dial a different number during the second attempt The real
time and date of occurrence of the event is stored in the
NMC9306 along with the outcome of the telephone call
This routine keeps track of the non-volatile memory capaci-
ty and if it overflows it prompts the user on the terminal of
the same The user is given the choice to overwrite the non-
volatile memory or replace the device
USING THE ASM SYSTEM
The ASM System upon installation and initial power-up has
some preliminary steps to be performed The time and date
should be set the phone number to be dialed by the Auto-
Dialer Unit should be programmed The toggle switch could
be used to toggle the display between Hours-Minutes and
Seconds-180th of Seconds
Setting Time and Date
The steps involved in setting the time and date are
1 Press key A on the keypad The LED display flashes
2 Set the desired time (Hours and Minutes) using the key-
pad
3 The LED display and the Terminal Screen displays the
time set
4 Press key C on the keypad The display toggles and dis-
plays the date
5 Press key A on the keypad The LED display begins to
flash
6 Set the date (month and day) using the keypad
7 The LED display now shows the date set
8 The LED display could be toggled to show the time using
the toggle switch However the system after one minute
will default to display time
Programming the Phone Number
The phone number to be dialed could be programmed in
two ways ie using the terminal or the keypad Using the
terminal the steps to be performed are
1 Press CNTRL B on the terminal keyboard
The
COP888CG sends a carriage return to terminal
2 Press CNTRL D on the terminal keyboard Then type the
number to be dialed At the end press CNTRL C to end
programming
Using the keypad perform the following steps
1 Press ‘‘ ’’ key on the keypad
2 Press the digits to be dialed
