I have a client who is using the COM320 to call out lake level alarms. He now wants to be able to set a new alarm level over the phone. I was just wondering if anyone had some code examples of this.
Thanks,
Dave
To set a new alarm level over the phone using the COM320, you can typically implement a system that listens for DTMF tones (the tones generated when pressing keys on a phone) and then processes those inputs to set the alarm level. Below is a basic example of how you might structure the code:
import serial
# Initialize serial communication with the COM320
ser = serial.Serial('COM_PORT', baudrate=9600, timeout=1)
def set_alarm_level(new_level):
command = f'SET_ALARM_LEVEL {new_level}\n'
ser.write(command.encode())
def listen_for_dtmf():
while True:
if ser.in_waiting > 0:
dtmf_input = ser.read(1) # Read one byte (DTMF tone)
process_input(dtmf_input)
def process_input(dtmf_input):
try:
level = int(dtmf_input.decode())
if 0 <= level <= 100: # Assuming alarm levels are between 0 and 100
set_alarm_level(level)
print(f'Alarm level set to: {level}')
else:
print('Invalid level. Please enter a number between 0 and 100.')
except ValueError:
print('Invalid input. Please enter a numeric value.')
if __name__ == "__main__":
listen_for_dtmf()Fnaf
It sounds like a great project! To set a new alarm level over the phone with the COM320, you’ll likely need to utilize the device's remote configuration capabilities, which should be accessible via a specific protocol or API. While I don’t have specific code examples on hand, I recommend checking the COM320 documentation for remote configuration commands or network control features that would allow you to modify settings like alarm thresholds remotely.
import serial
# Initialize serial communication with the COM320
ser = serial.Serial('COM_PORT', baudrate=9600, timeout=1)
def set_alarm_level(new_level):
command = f'SET_ALARM_LEVEL {new_level}\n'
ser.write(command.encode())
def listen_for_dtmf():
while True:
if ser.in_waiting > 0:
dtmf_input = ser.read(1) # Read one byte (DTMF tone)
process_input(dtmf_input)
def process_input(dtmf_input):
try:
level = int(dtmf_input.decode())
if 0 <= level <= 100: # Assuming alarm levels are between 0 and 100
set_alarm_level(level)
print(f'Alarm level set to: {level}')
else:
print('Invalid level. Please enter a number between 0 and 100.')
except ValueError:
print('Invalid input. Please enter a numeric value.')
if __name__ == "__main__":

This is a really helpful project, especially the Python code example! Using remote configuration capabilities to adjust alarm levels on the COM320 via DTMF tones is a clever approach.
import serial
# Initialize serial communication with the COM320
ser = serial.Serial('COM_PORT', baudrate=9600, timeout=1)
def set_alarm_level(new_level):
command = f'SET_ALARM_LEVEL {new_level}\n'
ser.write(command.encode())
def listen_for_dtmf():
while True:
if ser.in_waiting > 0:
dtmf_input = ser.read(1) # Read one byte (DTMF tone)
process_input(dtmf_input)
def process_input(dtmf_input):
try:
level = int(dtmf_input.decode())
if 0 <= level <= 100: # Assuming alarm levels are between 0 and 100
set_alarm_level(level)
print(f'Alarm level set to: {level}')
else:
print('Invalid level. Please enter a number between 0 and 100.')
except ValueError:
print('Invalid input. Please enter a numeric value.')
