To install the Transmitter:
4a. Connect the Transmitter to the audio source with a quality RCA or 3.5mm cable.
4b. If the application is point-to-point, then connect one (1) length of Cat 5e/6 (or
higher) grade UTP cable to the RJ45 LINK connector on the Transmitter.
5.
To install the Receiver:
5a. Connect the Receiver to the remote audio equipment with a quality RCA or 3.5mm
cable.
5b. If the application is point-to-point, then connect one (1) Cat 5e/6 cable (or higher)
coming from the Transmitter, to the RJ45 LINK connector on the Receiver.
6.
If the configuration is a point-to-multipoint or multipoint-to-multipoint:
6a. You will need to use an Ethernet Switch with Gigabit ports and DHCP Server support.
In addition IGMP Protocol support is required for the multipoint-to-multipoint case.
Verify that the Ethernet Switch is configured correctly and that the DHCP Server
is enabled and that the IGMP Protocol is enabled for multipoint-to-multipoint
applications
. See the Operating Manual for more information about configuring the
Ethernet Switch.
6b. Connect all Transmitters and Receivers to the Ethernet Switch.
6c. Use the DIP Switches to select a unique Device ID (dip switch positions #1, #2 and #3)
for each Transmitter present on the network and configure each Receiver Device ID to
the corresponding selected Transmitter. Note: This step is not necessary if the MuxLab
ProDigital Network Controller (500811) is used.
7.
Powering the Transmitter or Receiver via an external power supply is only necessary where
PoE (PSE) is unavailable. If PoE is unavailable, connect a 5 VDC power supply (500993 –
sold separately) to each Receiver and to an AC power outlet. Next connect each Transmitter
in the same manner. If power is present, the green power LED on each Transmitter and
Receiver will illuminate.
Note: Power ‘ON’ the AUDIO / RS232 over IP PoE Transceiver only after all data
connections have been made.
8.
Power ‘ON’ the audio equipment and verify the sound quality.
9.
IR Emitter and Sensor are not included, and are sold separately. If purchased, IR control
signals may initiate from control software on a PC, tablet, or smartphone connected to the
network, so that only IR Emitters are required next to the audio equipment. However IR
control may be initiated from a hand-held IR remote control and in this case the product
supports IR pass-thru control. In this scenario connect an IR Sensor to the 3.5mm Jack of the
Receiver and the IR Emitter to the 3.5mm Jack of the Transmitter.
Note: You can differentiate the IR Sensor and the IR Emitter by looking at the 3.5 mm
plug. The IR Sensor is using a Stereo Plug (3 Contacts) and the IR Emitter a
mono plug (2 Contacts).
10.
Position the IR Sensor so that it is directed at the hand-held remote control. For a clear IR
signal reception, aim the hand-held remote control at the top of the IR Sensor enclosure.
11.
Position the IR Emitter as close as possible to the source’s IR Sensor. For a clear IR signal
reception, the IR Emitter can be glued on the source’s IR Sensor. The IR Emitter’s signal is
transmitted from the side of the enclosure.
12.
This product supports RS232 bidirectional communication. On the Transmitter, the RS232
port is configured as a DCE; and on the Receiver as a DTE. Please connect your RS232 cable
accordingly. The default settings are 9600, N, 8, 1.
13.
To send an RS232 packet to a specific device, you need to put the IP address in front of the
packet. This communication is meant to be machine to machine; and hexadecimal codes
must be used. For example, to send the message “Hello” to a device having an IP address of
192.168.168.55 IP, send the following hexadecimal string: 0xC0 0xA8 0xA8 0x37 0x48
0x65 0x6c 0x6c 0x6f. (or “192 168 168 55 H e l l o” in hexadecimal).
14.
The following diagram illustrates a typical point-to-multipoint LAN configuration.
