Changing Values

To change the value of a function, the ADJUST knob or the left or right arrow
buttons can be used.

In the case of numerical values, there are two functional modes:

Operation

• If the overall range of an adjustment is small the

alters the value by the smallest amount possible.

• If a wider range of adjustment is required, a Delta value system is used.

Use the right arrow button to select the Delta value in brackets and
adjust it to the desired resolution by turning the
press the left arrow button to select the value then adjust it with the

ADJUST knob.

An example of this would be setting the Line Offset for SDI 1. Scroll down
from Digital Video to SDI 1. Select Video Standard then Timing and scroll
to Line and press the OK button. The Line Offset menu will be present on
the LCD. Note the Delta value on the right of the LCD indicated by a tri­angle Delta symbol = 1. You may change the Delta resolution value to 10 or
100 with the knob.

Use the left arrow button to select the Pixel choice field and turn the knob
to change the values to 1, 10, or 100. Note that when the Delta value is 1, the
values change by steps of one pixel. With a Delta value of 10, the pixels
change by steps of 10, 20, 30 etc.). Selecting a Delta value of 100 allows you
to change the pixels by 100, 200, 300 etc. Change the Delta resolution if you
need a finer offset setting.

As the parameter is changed, the new value will be shown on the LCD. For
some functions, the unit responds by actually altering the value immedi­ately. Otherwise the new value is applied when the

GPS Setup (7600 MHD-REF)

The GPS module comes with the 7600-MHD-REF model and is installed in
Slot 1. The Global Positioning System (GPS) is currently the only fully-func
tional Global Navigation Satellite System. More than two dozen GPS satel­lites are in medium Earth orbit, transmitting signals allowing GPS receivers
to determine the receiver’s location, speed, and direction.

GPS also provides a precise time reference used in many applications
including synchronization of telecommunications networks.

The GPS BNCs (and the AES unbalanced outputs) active on the 7600
MHD-REF model are shown in Figure 25.

GPS Antenna Requirements

The GPS module requires an external antenna with the following character­istics:

• Active single antenna is power from the 7600REF antenna connector

• 3V DC antenna is required

• Reception frequency optimized for 1575.42 MHz

• 10 dB to 50 dB gain as measured at receiver input (Antenna perfor-

mance dictated by antenna manufacturer)

• Connection by coaxial cable terminated in 50 ohm BNC male connector

• Maximum cable length controlled by signal strength and location.

Trimble cable is 25m/75ft (N.B. standard cable length is 5m or less on
some antennas.) Each extra interconnect will attenuate the signal and
could increase acquisition/response time.

• Mounting – ideally clear 360 degrees view of sky. Weatherproof mate-

rial for fixed installation.

Magnetic patch antennas suitable for vehicle mounting will also be satisfac­tory; the signal may be improved by mounting on minimum 3 inch/75mm
square steel plate.

tenance, or changes in local conditions in which the required signals have
been degraded such that time synchronization is lost.

Acquisition Process

With satisfactory reception, the acquisition process commences automati­cally and takes around 15 minutes. An enhanced mode (Site Survey) is suit­able for static installation and may be initiated from the Site Survey
selection on the GPS menu. A complete Site Survey can take around 2
hours. Once completed, it provides more accurate timing signals.

A 1 Pulse Per Second (1PPS) signal waveform is illustrated in

Figure 26. 1PPS Signal Waveform

The leading edge of the 6 ms wide, positive going pulse provides the timing
reference plane for locking external equipment.

Internally, this signal locks the 27MHz PLL Oscillator such that PAL output
signals are both frequency locked and phase locked. Any NTSC output
signals are frequency locked but cannot be phase locked.

This menu is detailed below.

Status – see Status Menu on page 51.

•

PPS Lock – it the PPS Lock mode is set to On, it only affects the Internal

•

Free Run mode of genlock. The internal oscillator is then locked to the
GPS reference.

Crash Lock – if the Crash Lock mode is set to On, the output signal is

•

subject to a single large disturbance followed by a period of approxi­mately 10 minutes for settling. If the Crash Lock is Off, convergence
may take many hours.

ATR Lock – ATR (Absolute Time Reference) is covered by SMPTE Pro-

•

posal 404 and is also known as SMPTE epoch. It defines a starting point
of midnight on January 1st, 1958, at which time all generating equip­ment is deemed to be phase locked By accurate determination of
current GPS time, any ATR equipment may be locked together again.
ATER also provides a time (and date) source for timecode generated by
the 7600 unit.

Figure 27 on page 56.

If ATR Lock mode is On, the unit will also perform a Crash Lock, inde­pendently of the Crash Lock mode described above.

• Site Survey – a site survey can take up to 2 hours to complete. It may be

initiated at any time, but would normally only be carried out when the
unit is in a fixed installation location with a high quality antenna. Status
of the Site Survey is shown in the Status sub-menu shown in Figure 28

Timecode Functionality (7600 MHD-REF)

Timecode is available with the 7600 MHD-REF model and provides the fol­lowing:

• 2 outputs of Longitudinal Timecode (LTC) on the LTC 9 pin Sub-D con­nector (refer to LTC Output (7600 MHD-REF Model) on page 25 for con-
nector pinout information).

• Vertical Interval Timecode (VITC) superimposed on analog video
waveforms. This is enabled or disabled in accordance with the current
group arrangement of the analog signal outputs.

• Each SDI output offers a combination of:

• Digital VITC (SMPTE S266) for standard definition signals only.

• ATC (SMPTE PRP188) for standard definition or high definition SD

signals.

On the 7600 MHD-REF model, the LTC functions, Timecode JAM and LTC
menu branches are accessed from the Setup menu explained below and
shown in Figure 29 on page 60.

Timecode Jam

This is the process of setting the time carried on the timecode stream. To
avoid discontinuity, it is important to carry this out carefully. The first
branch of this submenu list base oscillator frequencies (23.98Hz etc.) used
to drive the range of output signals. for example, to Jam the timecode for a
625 signal, select the 25 Hz option.

This submenu has the following modes:

Jam Source

•

• Manual: enter values manually

• RTC: uses the Real Time Clock, with the option to apply a manual

offset.

•JAM Mode

• Auto: sets a scheduled time

• Manual: on command

• JAM!: initiates the JAM procedure.

• Show Clock: shows the time currently carried on the LTC stream.

58 7600 SD/HD/MHD-REF — Instruction Manual

Operation

LTC

This submenu has the following modes:

• Mode – turns the timecode On or Off.

Frame Rate – since LTC is not encoded within a video signal, the frame

•

rate must be set either explicitly or by linked association with another
system output. Refer to LTC – Frame Rate Sub Menu on page 61.

Drop/Non-Drop – relates to 525/NTSC line timecode and determines

•

whether frames are dropped to compensate for the non-integer number
of NTSC frames per second.

Color Frame Flag – this is a single bit within the data stream which indi-

•

cates whether timecode is related to the video signal. This menu option
allows the operator to turn this bit On or Off.

Timecode Offset – an additional offset may be applied to any timecode

•

output with a value between -23h: 59m: 59s and +23h: 59m: 59s. The
default is 0h: 0m: 0s. This offset is applied immediately. Timecode
outputs using the same oscillator frequency will remain “in-step” using
the Timecode JAM settings applied in the Timecode JAM menu.

Binary Group Bits – the primary function of the Flag Bits is to allow the

•

operator to embed a date code within the data stream since timecode
represents only embedded time. This conforms to SMPTE S309. Refer
to LTC – Binary Group Sub Menu on page 62.

• Both Client and Server modes are available

• If installed, the menu will off Server, Client, and Disabled. Client and
Server are mutually exclusive. NTP is intended for change-over units to
keep them both in sync.

• The Client can sync to any Internet NTP server.

• When acting as a server the 7600REF should, ideally, have a GPS

7600 SD/HD/MHD-REF — Instruction Manual 69

Using a TFTP Server

Using a TFTP Server

The use of an TFTP server with the 7600REF models allows the customer to
upgrade software in the field, and, if necessary, generate a copy of the 7600
log file to send to Technical Support for troubleshooting purposes or option
enabling.

The 7600 log is a unique digital signature for each 7600 frame and describes
the options that have been enabled. As mentioned earlier, options come
already enabled from the factory so using this function to create a log file
for enabling options should not be required unless requested by Customer
Service.

However, software upgrades may be preformed in the field using the TFTP
server. See Updating 7600 Software on page 73.

To prepare a TFTP Server refer to Preparing a TFTP Server on page 71. The
suggested shareware application is called Solarwinds and can be down­loaded from http://solarwinds.net/downloads if required.

Run the installing program, accepting all default options. Note that you
may require Administrative rights under Windows to install new applica­tions.

Local Area Networks

In order to communicate with the TFTP server, the 7600REF must have a
valid IP Address in the same subnet (range) as the server.

• If communication is via a company network, then IP addresses may be
automatically allocated using DHCP.

• If the 7600REF is connected to a small network specifically established
for technical equipment, then static IP addresses may be in use and the
7600 should be configured accordingly.

• If the 7600REF is not currently connected to a LAN, Solarwinds may be
installed on a laptop which is then connected to the 7600REF with a
crossover cable.

The 7600REF Ethernet port is configured using the Setup menu, then navi­gating to the Comms menu. Refer to Setup – Comms on page 50.

Preparing a TFTP Server

Application of the supplied file requires the use of a TFTP server.

7. Install Solarwinds on a PC which will be accessible by the 7600REF. See

the discussion above on Local Area Networks on page 70.

8. After installation, from the Windows Start menu, launch Solarwinds

TFTP software and select Configure from the File menu.

9. Select the Security tab (Figure 38) and ensure that the Transmit and

Receive files option is selected.

Generating the Log File (Digital Signature)

1. Power up the 7600 and wait for initialization to complete.

2. Navigate to the Setup>>More>>Upgrades>>Server Address menu.

Enter the IP address of the TFTP server and press

This process is only necessary when enabling options which is done at the
factory. However, at some point this log may be needed when working
with Customer Service so the procedure is included here.

1. Navigate the 7600 to Setup>>More>>Upgrades>>Features>> Generate

Log.

2. A file will now be created in the TFTP root folder. Retrieve this file and

email it to Technical Support as requested.

3. This process is for enabling options which should only be necessary

when requested by Customer Service.

OK.

72 7600 SD/HD/MHD-REF — Instruction Manual

Updating 7600 Software

When new software code for the 7600REF is available it can come in three
forms:

•Firmware

• Changes to test patterns

• Changes to menu structure

This code may be installed using the TFTP server method (see Preparing a

TFTP Server on page 71) with a series of programming files which are avail-

able from Technical Support.

Note It is not necessary to generate the log file as described earlier in the option

upgrading explanation.

Preparing to Update

Refer to the following sections to set up your 7600 for TFTP server function­ality:

Using a TFTP Server

• Download and install TFTP Server (see Using a TFTP Server on page 70)

• Local Area Network considerations (see Local Area Networks on page 70)

• Preparing a TFTP Server (see Preparing a TFTP Server on page 71)

Preparing the 7600REF

1. Power up the 7600REF and wait for initialization to complete.

2. Navigate the 7600 to Setup>>More>>Upgrades>>Server Address.

3. Enter the IP address of the TFTP server as previously noted and press

OK button.

the

Completing the Process

1. Navigate the 7600REF to Setup>>More>>Upgrades and choose the

appropriate option for the component being upgraded.

2. The message, upgrade successful, appears on the 7600REF LCD screen

once the upgrade process is complete.

3. The unit is now ready for use with the new code installed.
