INSTALLATION AND OPERATION INSTRUCTIONS

INTRODUCTION

Thank you for purchasing your American Fibertek Series 8410C multimode four channel

video multiplexer with bi-directional Sensornet data. Please take a few minutes to read

these installation instructions in order to obtain the maximum performance from this

product.

FUNCTIONAL DESCRIPTION

The 8410C Series units operate as a transmitter / receiver pair for the transmission of

four simultaneous, real time baseband NTSC / PAL video signals with Sensornet data

over one multimode fiber optic cable.

The MTX-8410C transmitter accepts up to four video inputs and multiplexes these

signals along with the data signals onto a single optical output port for connection to the

fiber transmission system. Correspondingly, the MRX-8410C receiver converts the

optical signal to four independent video output signals along with the data signals.

The 8410C Series units operate on 50 um or 62.5 um multimode fiber. Refer to the data

sheets for detailed performance specifications.

The individual units may be configured for rack mounting or wall mounting depending

upon the position of the included mounting hardware.

INSTALLATION

THIS INSTALLATION SHOULD BE MADE BY A QUALIFIED SERVICE PERSON AND

SHOULD CONFORM TO THE NATIONAL ELECTRICAL CODE, ANSI/NFPA 70 AND

LOCAL CODES.

To install the MTX-8410C or MRX-8410C it is first necessary to mount the rack flanges

to the unit.

For rack mounting the ears are installed on the

sides of the unit with the surfaces that have

oval holes flush with the front of the unit as in

Figure 1. Mount the ears with the #10 flathead

screws provided. To mount in the rack cabinet,

use mounting screws that are appropriate for

the rack cabinet being used.

For mounting the unit flush to a wall or other rigid

surface, the ears may be installed on the sides

with the oval holes flush with the bottom of the unit

as in Figure 2. Mount the ears with the #10

flathead screws provided. Mount the

unit to a rigid surface using #10 (5mm) screws.

POWER SOURCE

The internal power supply accepts universal line voltage. Any mains supply from 100 to

240 VAC, 50 to 60 Hz, may be used without modification or adjustment. A universal

power connector is provided on the rear of the unit to facilitate connection to the power

mains.

POWER CONNECTION

The unit is supplied (in the US and UK only) with a three conductor power cord. The

“ground” conductor is directly connected to the chassis.

INPUT / OUTPUT CONNECTIONS

The fiber optic connection is made via a ST connector located at the back of the unit. Be

sure to allow sufficient room for the required minimum bend radius of the fiber cable

used.

Video input and output connections are located on the rear of the unit. A BNC connector

is provided for each channel. The video inputs are connected to an appropriate 75Ω

baseband video source such as a camera or a video recorder output. The 75Ωvideo

outputs can be looped through typical baseband video inputs of switchers, recorders and

other equipment as required. For proper operation, the outputs must be terminated with

75Ω. For optimum performance the video cables should be the shortest length of coax

practical.

Data input and output connections are located on the rear panel terminal block. A mating

plug connector is provided. The figure below identifies the specific connections for the

Sensornet data connections.

DATA CONFIGURATION

There is a rear panel data configuration switch bank preset at the factory for Sensornet

data transmission. With the exception of switch # 5, these switches must remain in the

positions shown below to properly transmit Sensornet data. Switch # 5 is used to apply a

120Ωtermination resistor across the data I/O connections. These units are shipped

with the data input/output connections unterminated. Move switch # 5 to the down

position if termination is required for your application.

MTX-8410C STATUS INDICATORS

The MTX-8410C transmitter provides the following front panel LED status indicators to

aid in installation and troubleshooting:

DATA

These indicators turn green when any data activity is present. An active DATA 1 LED

indicates data is present at the input /output terminals of the MTX-8410C. An active

DATA 2 LED indicates the MTX-8410C has seized the data carrier to allow data flow.

The intensity of the indicators will vary with input / output data patterns, however, the Tx

and Rx Carrier Detect LEDs will typically appear dimmer than the Sensornet Tx and Rx

LEDs. The data activity associated with these front panel DATA LEDs are listed below.

OLI

A bi-color LED indicator monitors the optical input power of the data signal that is being

received at the MTX-8410C from the MRX-8410C. AC power and optical input status

associated with this LED are summarized below.

MRX-8410C STATUS INDICATORS

The MRX-8410C receiver provides the following front panel LED status indicators to aid

in installation and troubleshooting:

OLI 1

A bi-color LED indicator monitors the power of the optical input signal that is being

received at the MRX-8410C from video channels one through four of the MTX-8410C.

AC power and optical input status associated with this LED are summarized below.

Please note that data is sent as a subcarrier on channel one’s video signal.
