Step-by-step
1) Navigate to Device Management Panel
2) Select the device to which you'd like to send a down-link
3) Click on "send command" and a window will appear. For sending AT commands or plain text, just go ahead. To send binary data, see instructions below.
4) Type in the command you'd like to send and press "send".
5) To ensure your down-link will be delivered to the device, optionally check "confirmed" in the drop-down.
To send binary data, also select "Hexadecimal Format". The text you enter will be interpreted as hexadecimal values and converted to binary. Flush queue will ensure that no other commands are executed before the one you just entered.
