Transmitter Monitoring and Control Dashboard
Locating Your Dashboard
Find the RJ45 connector on the back of your unit, your unit may not look like the one in the image, that's okay, this advice covers many models. Using a standard CAT6 network cable, connect it to one of the spare RJ45 ports on your router. Give it about a minute and it should connect and assign an IP automatically. Once this is done there are two ways load the dashboard into your browser:
1. WITH AN INTERNET CONNECTION
Enter into your browser URL:
https://www.aareff.com/ipconnect/[DEVICE NUMBER].
So for example, the unit shown in the image above is:
https://www.aareff.com/ipconnect/aareff-260426
2. WITHOUT AN INTERNET CONNECTION (LAN only)
You still need to download our aareffdeviceip.exe file, but you can do this from a different PC. Click here to download the Windows app:
https://www.aareff.com/aareffdeviceip.exe
Your browser may flag it as a danger or virus and block it, you can ignore or bypass these warnings, we ASSURE you it is not dangerous, it simply scans your LAN subnet looking for the Aareff device ID, nothing more. Run the file and it will show you the following cmd screen with the Address: (LAN IP number) of your device. Enter this address, in this example 10.0.0.36, into the browser URL bar.
PASSWORD
The default password is set to your six digit sale/order number an example is 654321. You can leave it on this password if you want, it is unique to you. Alternatively if you want to change the password simply enter in the SERV-CMD: input box at the bottom LAN_PASSWORD=[your-new-password-here] and press EXECUTE. It's important to use underscore _ and not -. If successful it will confirm the change in the log under the WEB tab.
Adjusting the Power and Frequency
Enter FREQ:[freq-in-mhz] in the SERV-CMD input box and press EXECUTE. The log under the WEB tab should update as shown in the image. For example FREQ:99.3, do not enter FREQ=99.3, this will fail.
Enter PWR:[number-between-0-and-1] in the SERV-CMD input box and press EXECUTE. The log under the WEB tab should update. For example PWR:0.5, do not enter PWR=0.5, this will fail. 0 represents the lowest power the transmitter will do. 1 represents the maximum power the transmitter will do. Any number outside the range 0 to 1 will not work. Also 0.5 will not result in half the power because FM amplifiers are not linear. To get the exact precise power you want, you need to experiment with this value until you see the correct value at FWD: in the TRANSMITTER display panel.
Transmitter AOIP Audio Input
The analogue XLR balanced audio is summed with the analogue decoded AOIP (Audio Over IP), so it's possible to have both at the same time. It is done this way to avoid having a switch to toggle between them. Both these inputs are applied to the input of the AUDIO PROCESSING stage.
If only XLR analogue is required, then the digital is disabled by entering AOIP_SOURCE=DISABLED in SERV-CMD:, then EXECUTE. If only digital audio is required, then simply leave the XLR inputs disconnected.
CONFIGURING THE AOIP DIGITAL AUDIO INPUT
The Audio Over IP, AOIP can be set to decode a standard http/s:// stream or an rtp:// low latency stream. This is simply set up with the variable AOIP_SOURCE= and submitting it to the SERV-CMD: input box and pressing EXECUTE. Here are some examples:
AOIP_SOURCE=DISABLED
This completely disables the AOIP so it is dead. In this mode only the audio from the analogue XLR inputs will pass.
AOIP_SOURCE=https://stream.rfm.fr/rfm-wr2.aac
This will send RFM Night Fever disco station from Paris to the transmitter simply using their Ice stream.
AOIP_SOURCE=rtp://0.0.0.0:5004
This will accept and send to the transmitter any audio coming in on port 5004 from the current LAN subnets. In this mode to get the audio to play, the SDP parameters must match the stream being sent or the decoder will crash and freeze. The current setting of the SDP parameter's are shown in the STREAMING panel as follows SDP: OPUS 48K 2CH PT96 96KBPS. The SDP parameters can be changed to match the incoming stream using the commands shown below submitted to SERV-CMD:
SDP_CODEC=OPUS
SDP_KBPS=96
SDP_SR=48000
SDP_CH=2
SDP_BIT=16
SDP_PAYLOAD_TYPE=96
AOIP_DB=0
◼ TRANSMITTER - It controls the gain in the D to A block shown in the transmitter diagram above. Most of the time it will be set between 0 and -3. The only time it needs to go outside this range is when the AOIP is is encoded obscurely low or high at the source.
◼ ENCODER - It controls the gain of the OPUS rtp:// STL stream, it does not affect the gain of the HLS stream
Examples: AOIP_DB=0 , AOIP_DB=-3 etc.
HLS (HTTP Live Streaming)
TECHNICAL AND ENGINEERING AUDIO MONITORING
The output of the AUDIO PROCESSING feeds the stereo coder of the transmitter, however in addition it also feeds the CPU where it is encoded into HLS (HTTP Live Streaming) and made available to the LAN and also to the Aareff servers for public access. This HLS stream was originally designed for station technical staff or engineers to use for monitoring. A free data allowance of 100GB per month is included for this.
INSTANT WORLDWIDE HLS BROADCASTING (FOR FREE!)
This stream is also perfect for large scale public streaming via your own website. Your transmitter has a built-in HLS encoder with a VPN that traverses any firewall, NAT etc. via any router, Starlink, 3, 4 and 5G internet connection. All this without any configuration, you just connect your transmitter to the internet and you're broadcasting on line. If you gain a huge amount of listeners, this will exceed the free quota of 100GB per month. In the event of this you will need to pay the excess data costs if you want to keep the streaming operational. We charge 10 USD per 500GB, this is a very low rate and very competitive compared to other companies offering this type of service.
FREE WEBSITE PLAYER DIRECT FROM YOUR TRANSMITTER
This player, which also shows the RDS text, can be embedded in any website.
Press the >> RED << speaker icon and it will start playing the demo transmitter in our workshop located in Dominican Republic using a standard office router internet connection.
This is so easy to add to your own web page, just paste in the code below. Change 'aareff-260426' to the serial number of your transmitter and hey presto! it will work to the world instantaneously!!

RDS (RADIO DATA SERVICE)
Enter any of the following RDS commands into the SERV-CMD input box. For example: type RDS-PS:RADIO FM then press EXECUTE. Be sure to use the : and not the = sign between the command and the value.
RDS-ON
RDS-OFF
RDS-PI[0000 to FFFF hexadecimal]
RDS-PS:[any string up to 8 chars.]
RDS-MS:[0 or 1]
RDS-TP:[0 or 1]
RDS-TA:[0 or 1]
RDS-AFNUM:[0 to 15]
RDS-AF:[Up to 15 freq. formatted eg. 88.1, 88.7, 94.8]

RDS-RT:[any string up to 64 chars.] Volatile for playout software
RDS-RT-PERM[any string up to 64 chars.] Non-Volatile saved to flash memory
RDS-SCROLL:[0 or 1]
DYNAMIC RDS COMMANDS
The RDS text RDS-RT field can be changed dynamically changing every 10 seconds by external studio computer, a Google Docs account or a http/https:// url. (ex, STUDIO-6879, http://domain.com/rds.txt) or for Google Drive, use the GDRIVE: tag followed by the File ID.
RDS_URL=STUDIO-[port] on same LAN
RDS_URL=[http://domain.com/rds.txt]
RDS_URL=GDRIVE:[1xY2z3A4b5C6d7E8f9G0]
STUDIO PC RDS TEXT SERVER
If the studio computer and the transmitter are on the same LAN connected by WIFI or cable, the following app. rds-text-server.exe will manage give the presenter easy access to updating the 64 char text string that is shown on the listeners radio. Click here to download the Windows app:
https://www.aareff.com/rds-text-server.exe
Your browser may flag it as a danger or virus and block it, you can ignore or bypass these warnings, we ASSURE you it is not dangerous, it simply reads an writes to file path entered and broadcasts the text picked up to the UDP PORT: (in our example 6879), nothing more.
