Provided by third party: The LEI-592P allows Internet Protocol (IP) captioning and IP audio in one unit. This allows the removal of the traditional 2 phone line setup without having to buy a new Internet capable encoder or signing up to a captioning service. The unit will be connected to the encoder via serial RS232 and have the analog program audio connected to it with a stereo mini jack. The audio will be sent out of the units Ethernet port and caption data will be received into the units Ethernet port. The gateway router that the unit is connected to would have to be set up to allow two ports to be forwarded. This device allows true IP captioning.
The LEI-592P has user selectable baud rates of 1200, 2400, and 9600, and either 8-N-1 or 7-O-1 type serial data, a standard 3.5 stereo headphone jack with volume control, and an Ethernet port for a broadband connection. The audio is sampled at 16 KHz allowing for audio that is better quality than Voice over Internet (VoIP) to be received by the captioner via TCP/UDP. Latency of the audio is less than 200ms plus the latency of the internet, the latency can also be adjusted thru the audio player. The serial and audio data is sent through two serial tunnels connecting to the captioner. IP address, port numbers, encryption and password security can be setup via a built in web page using a web browser.
The LEI-592P has a data LED to indicate receiving or sending data thru the Ethernet. It also has a LED for audio to indicate audio presence and audio clipping (input audio to high). The captioner will enter the IP address and port number of the LEI-592P into the player software and connect to the LEI-592P. The audio output device can be selected by the captioner thru the player software, along with audio volume control. The player can be minimized and can run in the background.
