Note: When installed in an electrically noisy environment, an STP cable must be
used. Also, cross-connections in the signal path reduce the effective distance
depending on the grade of twisted cable used.

Quick Installation Guide
Overview
The AUDIO / RS232 over IP PoE Transceiver allows 2CH audio signals to be extended up to 330ft
(100m) via one (1) Cat5e/6 unshielded twisted pair cable in a point-to-point configuration. Point-
to-multipoint and multipoint-to-multipoint is possible by connecting several Transceivers to the
same local Ethernet network, and the device supports PoE (PD) if used with a PoE (PSE) Ethernet
Switch. These Transceivers may be purchased individually (part number 500755) or as a kit of two
Transceivers (part number 500755-2PK). The Transceiver supports RS232 and IR transmission for
remote control of end devices. The IR Emitter (500998) and IR Sensor (500994) are not included,
but if required, may be purchased separately. The Transceiver can be configured as a Transmitter
or Receiver.
For the point-to-multipoint and multipoint-to-multipoint configuration the Ethernet Switch must
have Gigabit ports and DHCP Server capability and additionally support the IGMP communication
protocol for the multipoint-to-multipoint case. MuxLab recommends using the Cisco SG300 Series
Managed Switches.
The MuxLab ProDigital Network Controller (500811) is available to simplify the configuration and
utilization of the 500755 and other MuxLab IP based products via an Ethernet web interface.
Applications
Applications include; commercial and residential AV systems, classroom projector systems, digital
signage, boardroom systems, collaborative PC systems, and medical information systems, with
respect to the audio portion of these applications.
Installation
1. The Transceiver must first be set as either a Transmitter or Receiver. This may be
accomplished via the dip switch position #4. Reference the Operating Manual for further
instructions on how to set the dip switches. The remaining instructions are based on the
Transceiver being set as either a Transmitter or Receiver.
2. Identify the connectors on the Transmitter and Receiver as indicated on the product labels,
see the above front and rear product views for further details.
3. Verify that the distance between the Transmitter and Receiver is within MuxLab
specifications (see Specifications table for further details).
