VALID DATA TYPES
Most all operating command codes only require values of zero (0) through 9 or Zero (0) and Non Zero values. In some
commands where the data is optional or when the data is left off, either a read back of the command data occurs or a toggle of
the function occurs. Example, toggle from ON to OFF or from OFF to ON.
DATA TYPE EXAMPLES: 0 through 9
Zero (0) or Non Zero (1 through 9), which is used for ON/OFF or
ENABLE/DISABLE functions
3.8
OPERATING COMMAND CODE EXAMPLES
The most likely used command code will probably be ARM/DISARM. As an example of this command, send the password,
then arm the system by sending [01 11 1 #]. The first "01" is the ARM/DISARM command code, the next item "11" is the
key code, the third item "1" is the data which identifies that you want to arm the system and the last item "#" is the end of
string or enter key. If the command was correctly entered and executed the PET-820 will read back the new current condition
"ON". If you only wanted to interrogate the current arm condition you would send [01 11 #] (command code, key code and
enter key) and the PET-820 would respond with it's current condition "ON" or "OFF".

OPERATE COMMAND CODES
The following sections will detail each of the operating command codes to show syntax and examples of data values.
3.9.1
END COMMUNICATION
This command is used to terminate the communication with the PET-820. It will also reset the password and/or program
authorization mode so that the user is not required to reset those functions prior to issuing an end communication command.
If you wish not to issue an end communication command, you can hang up the phone and after a 3 minute period of no
communication (commands), the PET-820 will disconnect itself. If the "end communication" command is issued, the
disconnection will be identified with the message. "Good-bye, telephone call complete"
COMMAND CODE:
00
COMMAND SYNTAX:
00 #
EXAMPLE:
00 # = Ends communication
READ BACK:
"Good-bye, telephone call complete" = end communication
"Telephone call timed out" = no communication for 3 minutes
