INSTALLATION AND OPERATION INSTRUCTIONS
INTRODUCTION
Thank you for purchasing your American Fibertek Series 8810C multimode eight
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 8810C Series units operate as a transmitter / receiver pair for the transmission of
eight simultaneous, real time baseband NTSC / PAL video signals with Sensornet data
over one multimode fiber optic cable.
The MTX-8810C transmitter accepts up to eight 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-8810C receiver converts the
optical signal to eight independent video output signals along with the data signals.
The 8810C 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-8810C or MRX-8810C 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-8810C STATUS INDICATORS
The MTX-8810C 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-8810C. An active
DATA 2 LED indicates the MTX-8810C 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.
DATA 1 TX DATA 1 RX DATA 2 TX DATA 2 RX
Sensornet Tx Sensornet Rx Tx Carrier Detect Rx Carrier Detect
OLI
A bi-color LED indicator monitors the optical input power of the data signal that is being
received at the MTX-8810C from the MRX-8810C. AC power and optical input status
associated with this LED are summarized below.
