Sampling time interval, transmission power and repeater

Hardware
1

Hi,

I am new to NCD and Node-RED, and I have a few questions. I’ve recently purchased two Smart Industrial IoT Wireless Vibration Temperature Sensors (PR55-67A) and two Industrial IoT Wireless to USB Modems (PR55-17A) (Order #555563) for testing.

My questions are:

  1. How can I set the sampling time interval to 1 minute? I attempted to set the Delay to 60 seconds, but it did not work. (Still 5 minutes)
  2. How can I increase the transmission power of the sensor and receiver? Is this done through settings or by replacing with even higher-power antennas?
  3. How do I set up a repeater using the USB modem? How do i know that the repeater is functioning correctly?
  4. What do the on_request_timeout and lifetime_transmissions mean?

Thank you for your assistance in advance!

Best regards,
Howard

Hi,
the minimum interval is 5 min.
the power is set to max by default
Just power on the usb and it will start acting as repeater.
the number of messages device has sent since its inspection
