  • Customizable firmware based on project requirements
  • Continuous monitoring of pulse inputs and maintaining counters. Ideal for pulse based flow meter with forward and reverse flow pulses)
  • Continuous monitoring of analog inputs. Ideal for flow meter with 4-20mA or voltage outputs for flow rates.
  • Poll MODBUS RTU clients and decode data.
  • Server Communication using protocols like HTTP,MQTT or FTP
  • Communication of data to server based on specific events or on configured intervals
  • Storing and forwarding of data in case of communication failures
  • Programmable automation of DO operations by giving simple conditions for time, week day, DI status etc…
  • Operation of Digital output via SMS commands or commands from server
  • Generation of events on change of DI or DO and generation alerts to Server or SMS alerts to configured group of numbers.
  • Facility to store mobile numbers in different groups for authorization and SMS alerts
  • Configuration of parameters via serial port or remotely by SMS or from the Server
  • Facility to go on low power mode when there is no communication and automatic wakeup on incoming communication, serial events or DI events.
  • Watchdog timer
  • Over the air updation of firmware
Qt Serial Port Rs485

Qt Serial Port provides the basic functionality, which includes configuring, I/O operations, getting and setting the control signals of the RS-232 pinouts.

Serial Interfaces (RS232 and RS485) PCI Serial Interfaces 4-Port, RS-485. Qt 778981-01 NI PCI-8431/4 (RS485) 2 - 5 $ 495.00 Step 2: Select Optional Accessories. @SysTech said in QSerialPort, communicating through RS485: @Corpse0327 Having done this myself, MANY times here is my advice: Yes the data is unique to every device. There is no standard format, speed, or serial port data format. All devices pick. RS485 is primarily used in multi-drop configurations that make use of its balanced differential interface. Figures 3 and 4 show an RS485 pinout diagrams for 9 pin DB9 and 25 pin DB25 connectors. As displayed in the RS485 cable pinout, the interface has all signals in differential configurations.

The following items are not supported by this module:

  • Terminal features, such as echo, control CR/LF, and so on.
  • Text mode.
  • Configuring timeouts and delays while reading or writing.
  • Pinout signal change notification.
  • Special transceiver conditions, like Framing error, Parity error and Break condition error.
