on any unstable surface or table. The video prod-

uct may fall, causing serious injury to a person

and serious damage to the video product. Use

only with a mounting accessory recommended by

Vicon, or sold with the video product. Any mount-

ing of the video product should follow Vicon's

instructions, and a mounting accessory recom-

mended by Vicon should be used.

9. Ventilation - Slots and openings in the cabi-

net are provided for ventilation and to ensure reli-

able operation of the video product and to protect

it from overheating, and these openings must not

be blocked or covered. The openings should

never be blocked by placing the video product on

a rug or other similar surface. This video product

should never be placed near or over a radiator or

heat register. This video product should not be

placed in a built-in installation such as a bookcase

or rack unless proper ventilation is provided or

Vicon's instructions have been adhered to.

10. Power Sources - This video product should

be operated only from the type of power source

indicated on the marking label. If you are not sure

of the type of power supplied to your installation

site, consult your Vicon dealer or local power

company. For video products intended to operate

from battery power, or other sources, refer to the

operating instructions.

11. Grounding - This applies to video products

equipped with a 3-wire grounding-type plug, a

plug having a third (grounding) pin. This plug only

This prevents damage to the video prod-

uct due to lightning and power-line

surges.

15. Power Lines - An outside cable sys-

tem should not be located in the vicinity of

overhead power lines or other electric

light or power circuits, or where it can fall

into such power lines or circuits. When

installing an outside cable system,

extreme care should be taken to keep

from touching such power lines or circuits

as contact with them might be fatal.

16. Overloading - Do not overload wall

outlets and extension cords as this can

result in a risk of fire or electric shock.

17. Object and Liquid Entry - Never

push objects of any kind into this video

product through openings as they may

touch dangerous voltage points or short

out parts that could result in a fire or elec-

tric shock. Never spill liquid of any kind on

GENERAL

This manual is a guide to the installation and operation of

the V730 series fiber optic video/data transmission for

NOVA control systems. Please read the entire manual

before installing the equipment.

NOTE: The series numbers V730T and V730R will be

used to describe all models of transmitters and receivers

unless noted otherwise.

The V730 series of data transmission system offers

simultaneous transmission of duplex digital control data

and one-way 10-bit digital video. The V730 system oper-

ates over one or two multimode fibers. The system can

also be configured for contact closure in the Tx-to-Rx

direction, replacing the data signal in that direction.

A complete system consists of a transmitter, V730T, and

a receiver, V730R. Units are designed for standalone

operation or for installation in Vicon’ V515R-PS or

V517R-PS Card Cages (V730T-R and V730R-R).

The V730T transmitter has one video input, data

input/output, and one or two fiber connectors. The V730R

receiver unit has one video output, data input/output, and

one or two fiber connections.

Unpacking the Unit

In the event that anything is missing from the following

list, contact your authorized Vicon dealer or representa-

tive.

V730T Transmitter or V730R Receiver

Instruction manual

Save the original packing materials in case it becomes

necessary to return the unit.

INSTALLATION

Installation Considerations

This fiber-optic link is supplied in two forms, as a stand-

alone module and as a rack card. Units should be

installed in dry locations protected from extremes of tem-

perature and humidity.

Standalone Modules

1. Determine where the module is to be installed, and

ensure that there is adequate space at both ends for

making the various cable connections and for reading the

diagnostic LEDs.

2. Standalone modules are provided with mounting holes

for four No. 6 screws (3-mm or 3.5-mm screws). The type

of screw chosen must be suitable for the surface on

which the module is to be mounted.

Rack Cards

Rack cards are designed to be installed in one of Vicon’s

19-inch (483-mm) EIA standard card-cage racks, either

the V515R-PS or the V517R-PS. Follow these steps after

selecting data format, contact closure and alarm output.

CAUTION: Although a rack card may be installed with-

out turning off power to the rack (hot-swappable), Vicon

recommends that the power switch on the rack power

supply is turned OFF and that the rack power supply is

disconnected from any power source.

1. Make sure that the card is oriented right-side up, and

slide it into the card guides in the rack until the edge con-

nector at the back of the card seats in the corresponding

slot in the rack’s connector panel. Seating may require

thumb pressure on the top and bottom of the card’s front

panel.

CAUTION: Take care not to press on any of the LEDs.

2. Tighten the two thumb screws on the card until the

front panel of the card is seated against the front of the

rack.

Data Translation

The data translation capability of the V730 series is unique

in the industry. It allows translation from one format to

another, thus eliminating the requirement for external trans-

lation devices.

The translation is in the physical layer only; it cannot inter-

pret specific protocols, nor do command translations. Due

to the encoding schemes utilized in Manchester and

Biphase, these formats are exempt from translation. Data

translation examples are shown in Table 13.

Data Selection

NOTE: Units are shipped with all jumpers set for bidirec-

tional data. The Data Selection switch on standalone units,

or SW1 on rack cards, is shipped in the Disabled setting.

Using the rotary Data Select switch, select a valid data for-

mat according to the Data Select Settings listed on page 2.

NOTE: If the link is going to support RS485, refer to

NOTES ON RS485 APPLICATIONS on page 7.

Contact Closure Selection

Receivers: Receivers can be reconfigured for contact clo-

sure in the forward data path by setting jumpers W3, W4,

and W5 to the 2-3 position. Refer to Figure 2 for jumper

locations.

Transmitters: On transmitters, jumper W2 must be set to

the 1-2 position. To access this jumper, you must first

remove the front and rear panels from the standalone can.

Each panel is held in place by four screws which can be

removed with a 4 mm nut-driver. Remove the screws and

carefully lift the panels away from the can. Note that the

fiber connectors are mounted to the panels. After removing

the panels, lift the cover off to expose the circuit boards.

The jumper is located on the bottom board which is

attached to the mounting plate. The top board is connect-

ed to the bottom board via a 34-pin connector which must

be separated from its socket on the bottom board. Be care-

ful not to bend any of the connector pins. When the bottom

board is exposed, locate jumper W2. Remove the jumper

pin which is on the 2-3 position and place it on the 1-2 posi-

tion.

Reassemble the module. Carefully reconnect the 34-pin

connector being sure that all pins are correctly aligned and

inserted into the socket. Replace the cover and front and

rear panels, securing the panels with the screws removed

earlier.

NOTE: When using contact closure, the reverse data path

remains operational. Data can be selected via the switch in

accordance with the settings shown on page 2. Since the

data is simplex, however, the duplex data modes (Tables 2,

7, and 8 on page 7) will not apply.

Alarm Jumper

Rack cards are supplied with an alarm function that goes

active if the optical signal input to the receiver fails. The

alarm is always indicated on the front panel of the card by

a red Level/LossTM LED. The alarm may also be output to

the rack power supply, where a sonalert (audible alarm)

and alarm output contact closure may be activated.

The alarm is set to ACTIVE at the factory. If the alarm out-

put is not desired, remove jumper W2 from the rack card.

Refer to Figure 2 on page 3.

NOTE: Removing jumper W2 does not affect the operation

of the Level/LossTM LED. Loss of optical signal will always

be indicated by a red Level/LossTM LED.

CONNECTIONS

Data Connections: Connect the data cable to the remov-

able 8-pin screw terminal on the V730 according to Tables

1 - 8 for the data format selected above.

Contact Closure Connections: Contact closure connec-

tion is made according to Table 11 for transmitters and

Table 12 for receivers.

Video Cable Connection: Connect the video source cable

to the input BNC jack on the V730T transmitter. Connect

monitor equipment to the output BNC jack on the V730R

receiver.

Vicon suggests that Belden number 9259 or equivalent

coaxial cable should be used.

Fiber Optic Cable Connection: Most cable manufacturers

identify the individual fibers in the cable. Select appropri-

ately terminated fiber and mark both ends with unique iden-

tification label (e.g. for cable no. 03, fiber no. 08) to ensure

that the fiber connected to the near end is the same one

that is connected to the far end. The proper optical con-

nection will link the transmitter's OUT port to the receiver's

IN port.

1. Wipe the inside of the port’s sleeve with a lint-free pipe

cleaner moistened with reagent-grade isopropyl alco-

hol. Blow dry with dry air.

2. Clean the connector using a lint-free cloth dampened

with alcohol to thoroughly wipe the side and end of the

ferrule. Blow the ferrule dry with dry air. Visually inspect

the ferrule for lint.

3. Fasten the fiber optic cable to the port.

DIGITAL VIDEO / DATA FOR NOVA™ CONTROL SYSTEMS

Power Connections: Standalone transmitters may be

powered either by 24 VAC or by 12-16 VDC. Connect input

power according to the label on the module.

Rack modules power connections are made automatically

when the card is installed. To supply power to the rack,

connect the rack power supply to an AC outlet and set the

power switch to ON.

OPERATION

V730 links operate automatically once installed. To exe-

cute the test mode, see page 5. For an explanation of LED

color codes, see page 6 and Tables 14 and 15.

MAINTENANCE

There is no operator maintenance other than keeping the

units clean.

MODEL V730

RS485 APPLICATION NOTES

The V730 is configurable for both full-duplex (4-wire) and

half-duplex (2-wire) operation. It can be used for interfac-

ing to systems adhering strictly to the RS485 specification

and for use with systems that use a modified, "fail-safe

biased" RS485 bus.

Connection: Use high quality twisted-pair wiring, and

make sure all connection points are clean and tight. A

loose connection on one of the wires can appear to func-

tion, yet cause intermittent errors: data LEDs may be flash-

ing as signals pass through the system, but those signals

will be corrupt.

Configuration: Vicon V730 units are designed to work

with virtually any RS485 system. Unfortunately, some sys-

tems operate on a "modified" version of RS485; they use

failsafe biasing to pull up/down their bus during a tri-state

condition. In a standard RS485 system, when a driver on a

properly terminated bus goes into tri-state (inactive), the

voltage between the differential outputs should be less than

200 millivolts. (This is what is considered "standard offset"

in the product instruction manuals.) A differential output tri-

state voltage this small can cause some nonstandard sys-

tems to latch up, since they are designed for much larger,

"fail-safe," offsets. To be able to interface to such equip-

ment, the Vicon V730 offers two more "offset" level modes.

That is, the maximum differential input voltage that can be

applied where it will be perceived to be in tri-state. Of

course, the equipment manufacturer does not disclose this

information. In most cases, the Vicon unit should be config-

ured for "standard offset" operation. When the system is

operating properly, the DATA IN and DATA OUT LEDs will

be off when there is no communication (tri-state) and they

will flash when data is being sent or received. In the case

where the link is not functioning properly (LEDs will most

likely not turn off), change the DATA SELECT switch on the

unit to a higher offset mode. First try 1 V, then 2 V. If sim-

ply switching the mode switch does not prove effective, the

offset level may have to be emulated at one end of the sys-

tem by using pull-up/down resistors on the data connector.

The V730 has a +5 V bias pin and ground pins on the con-

nector for this purpose. Contact equipment manufacturer's

technical support for recommended resistor values and

configuration.

Termination: RS485 systems need to be properly termi-

nated in order to work reliably. Exactly two terminating

resistors are used on each RS485 bus, at the furthest ends

of the link. These resistors should be attached right on the

DATA IN/OUT connector if the Vicon link is at one end of

the bus. If the terminating resistors are left out, the tri-state

condition will not be detected, and the bus may lock up. If

there are too many terminations on the bus, signal levels

may drop too low, or driver circuitry may fail. The standard

value of terminating resistors for RS485 is 120 ohms.

TEST MODE

Test mode allows the end user to verify the operation of the

copper receiver/driver circuit in a V730, as well as the fiber

connection from one V730 to another. Using the test mode

is simple:

1. Switch the V730 to be tested into position F (TEST

MODE) on the rotary switch. At this end only, wire the con-

nector as shown in Table 9.

2. At the receiving (or opposite) end, switch the V730 to

position 9 on the rotary switch.

In the test mode, the transmitting unit should behave as fol-

lows:

A. Enabled LED is RED, indicating that a valid data format

has not been selected.

B. Data OUT LED is slowly flashing between amber, green,

and off. This indicates that the test mode is generating an

output pattern and sending it out on copper.

C. Data IN LED should mimic the DATA OUT LED. This

indicates a good, proper loopback connection, and proves

that the data transmit/receive circuitry is working properly.

D. Level/Loss may be red or green - indicates received fiber

signal strength.

The receiving unit (position 9) should behave as follows:

A. Enabled LED is GREEN, since a valid data format is

selected.

B. Data OUT LED should slowly flash amber, green, off.

This indicates that the fiber path from the unit set for TEST

MODE is reliable.

C. Data IN LED should be OFF, since there is no input cop-

per connection made.

D. Level /Loss should be green to off (but not red), indicat-

ing that sufficient optical power is being received.

After the test has been performed at one end, swap switch

positions and connectors to perform the test on the other

end. Having done this, you have proven that the copper-in-

to-fiber-to-copper-out conversion is working in both direc-

tions.

LED OPERATION

The V730 has 5 LED indicators that are very useful in

describing the current state of operation, as well as the cur-

rent status of data flow and fiber optic signal strength.

These indicators are LEVEL /LOSS, VIDEO IN (or OUT),

DATA IN, DATA OUT, and ENABLED. They function as fol-

lows:

LEVEL/LOSS: This LED is useful for indicating the relative

optical signal strength at the fiber optic receiver. When suf-

ficient optical power is being received, the LED shines

DIGITAL VIDEO / DATA FOR NOVA™ CONTROL SYSTEMS

green. As the optical power is decreased, as happens

through long fiber runs, splices, or connections, the intensi-

ty of the LEVEL/LOSS LED will diminish until the limit of the

V730's sensitivity range has been reached. At this point the

LED will appear OFF. If any additional optical attenuation

is introduced, the LEVEL/LOSS LED will turn bright RED,

indicating an insufficient amount of optical power is being

received. All data will default to its failure state level to

eliminate bus contention.

VIDEO IN (or OUT): This LED indicates the strength of the

video signal. VIDEO IN on the transmitter remains green

as long as adequate video signal is being input to the

transmitter. If the video input becomes too weak, the LED

turns red. The VIDEO OUT LED on the receiver performs

a similar function, except that it refers to the video that is

output from the receiver.

NOTE: The V730 monitors the sync signals on the video to

determine the strength of the signal. It does not monitor the

brightness signal. Thus, if the scene in front of a camera is

totally dark, producing a blank monitor screen, the VIDEO

LEDs can still be green.

DATA IN: The DATA IN LED indicates the level of the data

being input to the V730 over copper. A GREEN LED indi-

cates a logic HIGH is present on the copper inputs. A YEL-

LOW indication indicates a logic LOW is present on the

copper. No color (OFF) indicates a tri-state or high imped-

ance input. This can therefore be used to determine the

resting state of your equipment and, in the RS485 states,

verify that a tri-state is being detected properly. Unlike most

competing units, the V730 has special circuitry to capture

data transitions and make them visible on the LEDs. High-

speed bursts of activity, previously undetectable by stan-

dard LED circuits, can easily be seen by this special cir-

cuitry.

DATA OUT: The DATA OUT LED functions identically to

the DATA IN LED except that the LED represents data that

is being output from the unit. This LED has the same high-

speed capture circuitry described in the DATA IN section.

ENABLED: This LED has three states. GREEN, to indi-

cate a valid mode has been selected, RED to indicate an

invalid mode (spare or test mode) has been selected, or

FLASHING RED/GREEN to indicate that NO mode has

been selected.

Tables 14 and 15 provide a convenient summary of the LED

display functions.
