DH3 Not Communicating with an OleumTech Wireless Device
If the DH3 is not communicating with another OleumTech Wireless Device:
•
Update all devices with the same project file
•
Verify that all devices in the project file are also physically present and
uploaded with the same project file
•
Ensure all devices on the project file have the same security settings for
“Enhanced Site Security” and “Enable AES Encryption”.
•
Ensure the same site security key is on every device in the project file (only if
Enhanced Site Security is being used). Be sure to select “Update Key” when
updating devices.
•
Confirm that the antennas of all devices have a clear line of sight and are
within recommended distances
•
Increase the Tx Power of all devices
•
Verify transmitter interval settings (be sure to wait for the first transmit
interval for data after make any changes and updating the devices)
•
If there are other OleumTech equipment in the area on a different project file,
ensure the channel # is different to avoid RF interference and/or crosstalk
•
Verify that there are no possible interfering radios within the area. If so,
increase project file bit rate from 9600 to 115200.
•
Verify that the DH3’s radio setting for Retries is set to 3 (default value).
•
If possible, modify the transmitting frequencies of the other third party radios
to free up some bandwidth
•
Verify the latest firmware is installed on each device
