AOR ARL2300 (01) PDF MANUAL

The ARL2300 Ethernet Controller is an option for the AR2300, AR5001D, AR6000 and AR5700D communication receivers, which allows remote control and remote listening through the network.

The client software is based on the Java 2 platform and requires version 1.6 (Java SE 6 runtime) or higher to be installed on the PC on which it is running.

A good understanding of LAN, WAN, routers, IP addresses, port forwarding, etc., is necessary to set-up and use ARL2300. Very importantly, you must be able to set-up port forwarding on your own router. Make sure you have access to your router manual before going ahead in setting up ARL2300.

ARL2300 device (1)

Control cable (1) – Length 0.9m, straight D-sub 9pin

Audio cable (1) – Length 1m, 3.5mm stereo

Rubber feet (1) – Set of four

Printed manual (1)

CD-ROM (1) – Client software

-One straight LAN cable for connection between ARL2300 and your router. (Not supplied)

-One available LAN port on your router

Note: ARL2300 is receiving power directly from the receiver through the control cable. It does therefore not need to be powered by an AC adapter.

You need to have a GLOBAL IP address assigned to the external port of your router. Dynamically addressed IP addresses do often change by nature, therefore the client side would have no way to track the IP address changes and would not be able to connect to the remote receiver.

It is necessary to setup PORT FORWARDING in your router, towards the IP address of your ARL2300. Refer to your router’s manual on how to setup port forwarding.

When you connect to your ARL2300 over the network from the client side software, you must first input the IP address of ARL2300 (or external IP address of your NAT router when using NAT) as a target. You can also input a hostname which shows the IP address registered in the DNS.

If you have changed the receiver’s serial communication settings from the default values, make sure to revert to following:

Communication speed: 115200bps

Interface: USB priority, or AUX priority, or AUX only

Flow control: none

After switching the receiver OFF, use a “minus” driver to put the S2 #2 dip switch into position ON.

Warning: Changing dip switch settings while the receiver is ON will cause receiver malfunction!

For AR2300: The power switch is on the front panel.

For AR5001D/AR6000/AR5700D: Use the main power switch on the BACK of the receiver.

With the receiver being switched off, connect the cables as follows:

1. Connect the Audio cable from the receiver’s rear panel SP jack to the ARL2300 front panel Audio IN jack.

2. Connect the Control cable from the receiver’s rear panel AUX port to the ARL2300 rear panel Receiver port.

3. Connect a LAN cable from your ROUTER or HUB to the ARL2300 rear panel LAN port.

Warning: Connecting / disconnecting the control cable while the receiver is ON will cause a receiver malfunction!

Remarks: On the receiver side, the audio cable can alternatively be connected to the back-panel’s LINE output or the front panel’s PHONES output. Audio level adjustment is not possible when connected to LINE.

Right after power is on, the red STA-L led will be lit. After approx. 1 minute, ARL 2300 will enter in stand-by mode, the red STA-L led will go off and the green STA-A will be lit. The time necessary to enter the stand-by mode might vary depending on the network environment.

The ARL2300 settings are accessible with a browser using ZEROCONF, a service discovery protocol based on Apple Inc.’s BONJOUR software. The IP address and host name are assigned automatically, providing your computer has Apple’s BONJOUR installed, and that your PC is connected to the same LAN than ARL2300.

Although the ARL2300 settings page can be accessed at any time, network configuration changes can only be done when ARL2300 is in stand-by mode (only the green LED is on).

To open the settings page of ARL2300, type the address http://arlan-0.local:48753/ in the browser bar.

You will then be asked to enter the user name and password (neither can be changed).

User name: Admin

Password: Arl_2300

WINDOWS 10:

* However, the Windows Network profile must be set to “public”, nor “private”.

** Due to Win10 zeroconf/mDNS firewall bug

If your Windows version has been updated to 1909 and the address is not accessible, you can use the AOR utility ARL2300discover.jar and copy/paste the IP address found by the utility, to your browser.

iPhone:

Connect to the same network than ARL2300, and access http://arlan-0.local:48753/ via the browser.

ANDROID:

Browsers cannot directly access http://arlan-0.local:48753/. However, the Android app “mDNS” made by Network Revolution can find out the ARL2300 IP address on your network, from the host name “arlan-0”.

By default, “Obtain an IP address automatically” is selected, nevertheless you can choose to manually enter address parameters to match a particular network environment.

IP Address(required): IP address you wish to allocate to ARL2300.

Netmask(required): Netmask for ARL2300 according to the specific network environment.

Gateway: Gateway for ARL2300 according to the specific network environment. Leaving it empty is as if you entered the values 0.0.0.0.

NameServer: NameServer for ARL2300 according to the specific network environment. (Required for firmware update).

You need to open the following ports on your (NAT) router and to forward these ports to the ARL2300. Receiver remote control will not function unless port forwarding is correctly set. Each port number can be set to any value between 10001 and 65535.

TCP Port: Port used to send the control commands to the receiver.

UDP Port: Port used for audio from the receiver.

Conf Port: Port used to access the ARL2300 settings via the browser.

Timeout: Set the range from 10 to 60 seconds, in 5 seconds steps. If the command data from the client software is not received within the time set here, ARL2300 will cut the communication with the client.

Authentication: Here you can restrict access from the client software by setting a username and password of your choice. User and Password length: 8 to 16 chars. Acceptable chars: 0 to 9, A to Z, a to z and . _ – . Leaving blanks would allow anyone to access ARL2300.

Save options:

Reload(without SAVE): Reverts all settings to the last saved state.

Quit(without SAVE, LOGOUT): Quit the settings page without saving any changes you might have made.

Save: Settings are saved. At this stage, the changes have not been implemented by ARL2300 yet, as it needs to be rebooted.

Once your changes have been saved, the summary of your ARL2300 configuration will be displayed and you will be given the following choices:

Reboot: ARL2300 will be rebooted and the changes implemented.

Quit without Reboot: Logout from the ARL2300 settings without rebooting ARL2300. The settings changes you have previously saved are not implemented yet by ARL2300.

Return to Config: In case you need to edit the settings again.

The IP address of the currently connected client will be displayed in the “Current connection status” section. Click the “Force disconnect” button to force disconnection of the currently connected client.

If no client is connected, it will show “Not connected.”

While you access the settings page, the “current connection status” is not automatically refreshed. You would not know if a client accesses ARL2300 while you are on the settings page, unless you click the “Update information” button.

The ARL2300 firmware can be updated online, using ports TCP 80 (HTTP) and 443 (HTTPS). Make sure that your router does allow ARL2300 to access these ports; otherwise the firmware update will fail. Please consult your router documentation on the port access procedure.

To proceed with the update, click on the “Move to ARL2300 firmware update page” link at the bottom of the ARL2300 settings page.

WARNINGS:

The firmware update process is done entirely at your own risk.

Ensure that you have an Internet connection.

Default gateway and DNS server settings are required for firmware update.

During the firmware update process, do not interrupt the process. The update takes approximately 5-10 minutes.

Do not remove power at any time during firmware update.

Never disrupt an Internet connection during the firmware update process.

Do not close or exit the browser during firmware update process.

When the firmware update is complete, the system automatically disconnects the host connection and reboots the ARL2300.

Click “YES” to start the update. The screen will inform you on the update progress. At the end of the firmware upgrade, ARL2300 is automatically rebooting. Disregard any message saying that the Internet connection was interrupted.

Do not execute the client software directly from the CD. You first need to copy the software folder to your client PC.

Enter the following information:

Address: Enter the IP address or hostname of the ARL2300 Ethernet controller. Factory default hostname is: http://arlan-0.local

User, Password: Enter the username and password assigned to the ARL2300 Ethernet Controller. Factory defaults are User: arl2300x, Password: Arl_2300Q

TCP, UDP: Enter the TCP and UDP port numbers assigned to the ARL2300 Ethernet Controller. Factory default is 48752 for both.

“Busy!” error: ARL2300 only allows one client connection at a time. This message means somebody else is already connected.

“Cannot connect to host (ARL2300)” message: Possible reasons for this error message are:

– The IP address (or host name) for ARL2300 or its TCP port number you entered in the client software, are incorrect.

– The IP address, when using dynamic DNS on ARL2300, has not been updated.

“Login incorrect” error: The user name and/or password you entered are incorrect. Entries are case sensitive.

No Sound after connection: If you can connect to ARL2300 but hear no sound, then most probably the UDP port number is incorrect.

Checking the “Terminal” box at the bottom right of the client software control screen does open the terminal command window. To send a command to the remote receiver, type the command in this terminal window and hit the Exec button. Please note that here you can only SEND commands but this window will not show you the response sent by the receiver. The software will interpret the responses in its interface.

As an alternative to the AOR software, you can use a Telnet software to test commands and their responses.

TCP is used for control data communication between ARL2300 and the client software. The connection procedure is as follows:

1. Connection starts. ARL2300 sends “330 +OK”. If another client is connected, it sends “420 Sorry, already connected” and terminates.

2. Client sends “USER (user name)”. One blank space is needed.

3. ARL2300 sends “331 +OK”. If the user format is illegal, it sends “500 format error” and terminates.

4. Client sends “PASS (password)”. One blank space is needed.

5. ARL2300 sends “231-@” followed by other initialization messages (“232-TIMESTAMP”, “233-ADDLM”, etc.) and ends with “230 Welcome”. If the password is incorrect, it sends “530 Login incorrect” and terminates.

After a “230 Welcome” message, the receiver is under remote control. Commands should be terminated by <CR> or <CR><LF>.

The special CPF (Special Command Prefix) is a header character that controls ARL2300. If data is sent to the ARL2300 without special CPF, the data is applied to the receiver directly. No data is passed on to the receiver if ARL2300 received the command with special CPF, and the data is used to control the unit.

To receive UDP data (audio data) from the remote ARL2300, the client PC needs to send the “p” command. The UDP command is @p1. This command should be sent to the ARL2300 every 10 to 120 seconds until audio transmission is stopped. To temporarily stop the UDP data transmission, the q1 command should be issued. To stop the UDP data transmission completely, the q command should be issued.

AUDIO DATA: Audio data is an uncompressed PCM with symbol consisting of 16-bit little-endian format. One payload can carry 800 octets as initial value. The size can be changed by “b” command.

SEQUENCE NUMBER: Every single octet data send over UDP has a sequence number between 0 and 255. The sequence number increases in every UDP packet transmission.

TIME-STAMP: The time-stamp format is a value in seconds started from Jan 1, 1970 (aka UNIX time). The inclusion of TIME-STAMP can be selected by the “t” command. The default value is t0 (No TIME-STAMP is added).

LM VALUE: The LM value space of the UDP payload stores the leading 9 characters string of the actual LM value. The inclusion of LM can be selected by the “l” command. The default value is l0 (No LM value is added).
