I/O — Digital Input and Output lines. A 5-pin inline receptacle whose mating plug uses
screw terminals to accept bare wire.
GND — Signal ground.
I/O 1 — (COR) Pull low to stream RTP audio packets to the network.
I/O 2 — (PTT) Goes low to indicate RTP packets are being received from the network.
D+ and D- — RS485 data loop; not implemented.
LAN — Standard 10/100BaseT Ethernet port with RJ-45 pin-outs following the AT&T T568B
specification. A standard Category 5 LAN cable connects it to an Ethernet switch.
USB — Allows a trained technician with a correctly setup computer to establish a direct
serial connection to the AudioMate 360 internal Diagnostic Console. Connects via a standard
USB A to Mini-B cable. The computer must have the Virtual Comm. Port driver from FTDI
(ftdichi p.com) installed along with any standard terminal emulator. This port is used for
diagnostics; no voice parameters can be set.
 V — 12 Volt d.c. input, tip is positive, ring is negative. The supplied power adapter converts
120 Volt a.c. main power to 12 Volts d.c. at 500 mA maximum. The power plug has a 1.3mm
inner diameter.
Rear Panel Controls
Reset — This recessed push button reboots the processor in the AudioMate 360. Depress
using a pen or any device with a small tip. The length of time that it is held depressed
determines the type of reset:
Quick Reset – A momentary press performs a simple reset.
Factory Reset – Press and hold until OK light goes from AMBER to GREEN to reset those
options found on the web configuration screens to factory defaults. While the AudioMate
360 is awaiting an address from a DHCP server this could take as much as 60 seconds. In
order to ensure that the device loads factory default settings the Reset button must be
held this entire time, until the OK light changes from AMBER to GREEN.
Installation
Network Considerations
In the typical AudioMate installation all endpoints are contained entirely in a corporate
LAN, or participate via a WAN link, either unicast through a VPN or an engineered MPLS
network, for example. It is preferable that all routers serving network segments that
connect AudioMate endpoints be configured to route multicast streams. This can smooth
implementation of multicast systems in general (such as videoconferencing), and the
deployment of AudioMate Communicator remote control soft consoles in particular.
Multicast is used to allow multiple endpoints to share one stream of audio packets, thus
reducing bandwidth consumption. However, while multicast streams typically pass
seamlessly through Ethernet switches, they are typically blocked by most routers unless
proper preparations are made to accommodate multicast. It is a near certainty that multicast
