Introduction
Thank you for purchasing ARL2300.
The ARL2300 Ethernet Controller is an option for the AR2300 and AR5001D 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.
The settings of ARL2300 can be easily changed through the local network (DHCP mode) by
using a browser, based on Apple’s “Zero configuration” software Bonjour.
To obtain the best possible results from your ARL2300, we strongly recommend that you read
this manual and familiarize yourself with ARL2300.
As for any network related remote control device, 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. As
there are hundreds of different router models on the market, with almost as many
different ways to configure them, AOR is unable to assist you in troubleshooting port
forwarding and network security issues.
Every effort has been made to make this manual correct and up to date. Due to continuous
developments of the device, we acknowledge that there may be some errors or omission
anomalies.

 ARL2300 device 1
 Control cable 1 Length 0.9m, straight D-sub 9pin
 Audio cable 1 Length 1m、φ3.5mm stereo
 Rubber feet 1 Set of four

What you need to prepare:
-One straight LAN cable for connection between ARL2300 and your router.(Not supplied)
-One available LAN port on your router
Note： When used with the AR2300/AR5001D receivers, ARL2300 is receiving power directly
from the receiver through the control cable. It does therefore not need to be powered
by an AC adapter.

3 Typical client / server network
Case 1: Through a router with NAT.
 You need to have a GLOBAL IP address assigned to the external port of your router.
(Please inquire your internet provider to this effect) 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. See chapter 6 “ARL2300 settings” regarding the related port numbers
and IP address. Please refer to your router’s manual on how to setup port forwarding.
Case 2: Through the Intranet (router without NAT)
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.

■Receiver serial communication settings
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
■Setting the receiver’s DIP switches
After switching the receiver OFF, use a “minus” driver to put the S2 #2
dip switch into position ON, as described in this graphic >>
Warning: Changing dip switch settings while the receiver is ON
will cause a receiver malfunction!
AR2300: The power switch is on the front panel
AR5001D: Use the main power switch on the BACK of the receiver.

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