1.1 General description
The Model 9311T and 9311R Fiber Optic RGB High Resolution Video Transmitter/Receiver pair allows the user
to remote the video monitor from the video generator via a much longer distance than allowable via copper
coaxial cables. They may also be used when electrical isolation or immunity from noise in the transmission
path is required.
There are three optical versions:
A.
B.
C.
The “H1” transmitter (using an 865 nm LED)/“S” receiver combination provides a video bandwidth of up
to 180 MHz via short fibers. The bandwidth falls to about 105 MHz after approximately 600 meters of fiber
and 50 MHz at 1200 meters. For this combination the primary effect on the bandwidth is chromatic
dispersion in the fiber, which is not greatly affected by fiber type.
The “S” transmitter (using an 850 nm multimode LED) /“S” receiver combination provides a video
bandwidth up to 160 MHz via short fibers. The bandwidth falls to 90 MHz after approximately 600 meters
of fiber and to 40 MHz at 1200 meters. The primary effect on the bandwidth is the chromatic dispersion,
which is not greatly affected by the fiber type.
The “LD” transmitter (using a 1310 nm single mode laser emitter)/“L” receiver combination provides a
video bandwidth of up to 220 MHz via short fibers. The bandwidth is valid for the entire link budget.
The units require three optical fibers to operate. The sync signals are combined and sent with the video on
these fibers, eliminating the need for a fourth or fifth fiber to carry the sync signals. They support each of the
following sync input/output combinations:
INPUT
Sync-on-Green
External Composite
External Horizontal and Vertical
External Composite
External Horizontal and Vertical
External Horizontal and Vertical
OUTPUT
Sync-on-Green
Sync-on Green
Sync-on-Green
External Composite
External Composite
External Horizontal and Vertical
NOTE: VGA, SVGA, XGA, and SXGA fall into the last category.
In the transmitter, all sync signals are first removed from the input(s). Then calibrated sync signals are added
to all colors for transmission via the fiber. These sync signals are used as the Automatic Gain Control (AGC)
references by the receiver. These sync signals are then removed by the receiver unless operating in Sync-onGreen mode. In this case the sync signal is not removed, allowing it to be present on the Green video output.
If external sync signals are input to the transmitter it is possible to use a Sync-on-Green monitor by enabling
the Sync-on-Green output at the receiver via an on-board dipswitch. In addition, if Sync-on-Green is input to
the transmitter, a separate TTL composite sync will be present at the output. If separate horizontal and
vertical syncs are input to the transmitter, separate TTL H&V sync output signals will be available on the
HS/CS and VS pins of the HD15 female connector on the receiver. If separate composite sync signals are input
it is possible to enable a TTL composite sync from the HS/CS pins of the HD15 connector at the receiver by
setting the appropriate on-board dipswitch.
4
The transmitter will accept external sync inputs of either applied positive or negative going sense and the
receiver will return them in the same sense as input. If Sync-on-Green only is utilized, the separate TTL level
composite sync output will be negative going. This feature of returning the external sync in the same sense as
applied allows the units to be transparent to any video/sync formats (such as VGA) which utilize the sense of
the sync signal to help the monitor identify the scan rates utilized.
The transmitter automatically senses the presence external sync signals and configures itself accordingly. If no
external sync signals are applied it will operate in Sync-on-Green mode and utilize the sync detected from the
Green channel. If a sync input is detected on the HS/CS input and it is recognized as a composite sync (sync
OK indicator Green) it will operate in external composite sync mode. If a horizontal sync is detected at the
HS/CS input a vertical sync is not, the units will not operate properly (as indicated by a RED Sync OK indicator
on the transmitter). If both external H&V sync are applied to the transmitter it will operate in that mode.
VGA/SVGA/XGA resolutions of up to 1840 x 1634 are supported depending on fiber type and model selected.
Horizontal scan rates of 15.75 kHz to 128 kHz and vertical rates of 45 Hz to 150 Hz are supported.
The Models 9311T and 9311R are single-width card compatible with the 9000 series of card chassis. They
operate on 6VDC power from the chassis backplane. For rack-mount operation use the Model 9002 chassis.
For standalone operation use the Models 9003 or 9004.
The Models 9311T and 9311R are compatible with the standalone models 3654AR and 3654AT, respectively,
and the older System 5000 compatible Models 5654AR and 5654AT, in the multimode versions only.

2 - INSTALLATION
2.1 Set Up
Both the Transmitter and Receiver units have two-position dipswitches on the circuit card.
2.1.1 9311T
2.1.1.1 External Sync Input Impedance Select
On the transmitter, a dipswitch is used to select the input impedance of the external sync inputs,
HS/CS and VS. See FIGURE 1 for the location of the switch on the circuit card. Position one (1) is for
the HS/CS input. Position two (2) is for the VS input. Set the switch OFF for300 ohms and ON for75
ohms. Use 300 ohms as the default, 75 ohms if required usually for proper termination of long cables.
2.1.2 9311R
2.1.2.1 Sync-on-Green Output Enable (with external sync inputs)
On the receiver a dipswitch (position #1) allows the user to select a Sync-on-Green output from the
receiver in the absence of a Sync-on-Green input. See Figure2 for the location of the switch on the
circuit card. When switch position number one (1) is OFF the receiver will output Sync-on-Green from
the Green output only if the transmitter has a Sync-on-Green input with no external sync input. If
there is an external sync input there will be no sync signal on the Green output. When this switch is in
the ON position sync will be added to the Green output if an external composite sync(CS) is input to
the transmitter. This will allow for the use of Sync-on-Green monitors when only an external composite
sync (CS) or external horizontal (HS) or vertical syncs (VS) are available at the transmitter.
2.1.2.2 Composite External Sync Output Enable (with separate horizontal and vertical sync inputs)
On the receiver a dipswitch (position #2) allows the user to select an external TTL composite sync
output even though separate external horizontal and vertical sync signals are input to the transmitter.
This will allow for the use of an external composite sync monitor.
2.2 Mounting
To install the Model 9311T or 9311R,plug it into the card chassis
In mounting the chassis itself, make sure there is enough space to connect both the electrical and optical
cables to the panel without stressing them beyond the manufacturer’s limitations (bend radius minimums).
10
2.3 Power Cabling
Power is supplies via the chassis backplane for either a Model 9010 in-line power supply (for the Models 9003
or9004 chassis)or the Models 9030 or 9050 power supplies (for the 9002 chassis). Follow the instructions in
the power supply manual.
2.4 Optical Cabling
Connect a fiber from the R port of the transmitter to the R port of the receiver. Repeat the connections for the
G and B ports. Because of optical pulse propagation delay in the fibers, it is important to make sure the
fibers are of equal length to avoid misconvergence of the colors on the monitor.
Most cable manufacturers identify the individual fibers in the cable. Ensure that the same fiber connects the ‘R’
optical output port of the transmitter and the ‘R’ optical input port of the receiver, etc.
When making the optical connections, first remove and save the plastic dust caps from the optical ports on
both units and from the fiber terminations. Clean the ends of the fiber per supplier’s recommendation. ST
connections are made by taking the following steps (see Figure 3, below).
Figure 3 — ST CONNECTION
A) ST® OPTICAL CONNECTION
1) Align the key and the bayonet slots on the ST
connector with the keyway and the bayonets of
the ST optical port.
2) Slide the connector ferrule into the port until the
key and bayonets are engaged.
3) Push the coupling nut forward until it can be
turned clockwise to lock the connector into the
port.

2.5 Elctrical Cabling
The Video and Sync connections are made via the HD15 Female connectors on the front panels of the 9311T
and 9311R.
2.5.1 Model 9311T Transmitter
If the video source is a personal computer, the video/sync connection from the computer to the 9311T
is most likely made using a standard pin for pin VGA extension cable with a male HD15 connector on
one end and a female HD15 connection on the other. If your video source uses BNC connectors for the
outputs, use a standard 3,4, or 5 (as required) BNC-to HD15P (Male) adapter cable. All coaxial cables
should be the same length.
11
2.5.2 Model 9311R Receiver
If the receiver will drive a standard VGA monitor with an attached cable, a male-to-male HB15 gender
changer will be required to attach to the HD15S connector on the front panel. If your video monitor
has BNC inputs, use a standard 3, 4, or 5 BNC-to-HD15P (male) adapter cable (as required). All coaxial
cables should be the same length.
3 - OPERATION
3.1 Turn-on Procedure
To operate the units, connect the AC power cords and turn on the power switches on the
power supplies (if applicable). Confirm that the indicator lights come on.
3.2 Confirmation of Proper Operation
If operating properly, the green “SYNC” indicator on the transmitter and all three “LVL” indicators on
the receivers will be illuminated Green. Good video transmission will also be in evidence. On the
transmitter, if external sync inputs are present, either the HS/CS only or both the VS and HS/CS sync
LEDs will be illuminated.
