Multi-Functional Series 91PxxxxyE Platform

Overview

This document illustrates how afi’s innovative and highly flexible 91PxxxxyE platform can be utilized to
seamlessly integrate (bridge-the-gap) between Analog Video Systems and IP based technologies, on 1 optical
fiber.

Serial

Data

The 91PxxxxyE product platform digitizes and transports one analog video channel, a 10/100Mb/s Fast Etherne t
Channel supporting two Ethernet ports, optional two bidirectional audio channels, and up to four optional Multi-
protocol Data or Contact Closure channels over a fiber link. All product variations are available for both multimode
and singlemode applications.

The optional Multi-Protocol Data (MPD) or Contact Closure channels provide additional transport for any
combination of bi-directional dat a or bidirectional contact closure. The MPD features s upport RS232, RS485
2W/4W and RS422 and are protocol selectable using rear panel dipswitches. The standard Contact feature
utilizes normally open (NO) dry contact relays as the default. Normally closed (NC) relay option is also available
(consult factory).

Product Overview

Analog Video, Ethernet, Bi-directional Audio, Multi-Protocol Data, Contact Closure

The 91PxxxxyE is designed with installation friendly connectors that support various signal types. Video input
and output is provided on a standard 75ohm BNC connector. Each of the two 10/100 Ethernet port provided
uses a standard RJ45. A high -density 25 pin D connector is used for the data or contact inputs, the data or
contact-relay outputs and the audio input and output connections. To facilitate making connections to the D­connector, afi provides an adapter board that performs a D-connector to terminal block conversion.

Configuration Options

The simplest product configuration is the MT/RR-91PE (multimode) or MT/RR-91PESL (singlemode) which
supports one channel of analog video and two 10/100 BaseTX Fast Ethernet ports. This product option is housed
in single PCB card extrusion or rack card assembly since an upper board is not required to support the option
modules and audio channels.

The MT/RR-91P8E, (SL) supports one channel of analog video and two 10/100 BaseTX Fast Ethernet ports on
the lower board in combination with 2 channels of audio which are provided on the upper board. The upper main
board attaches to the lower board via an interface header connector. This product configuration is housed in a
double PCB card extrusion or rack card assembly. The audio channels are an option and are designated by the
number 8 in the part number.

The MT/RR-91Pxxxx8E, (SL) supports one channel of analog video and two 10/100 BaseTX Fast Ethernet ports.
Two channels of audio and up to four optional MPD data or contact closure channels are also supported. This
product configuration is also housed in a double PCB card extrusion or rack card assembly.
