There are a number of basic concepts that once understood will simplify the use of the unit as described below:
Valid button pushes are indicated by a lamp lit inside a button. In most cases, buttons without a lamp will not be prohibited, allowing rapid changes between functions grouped on each button.
Invalid button pushes will result in an informative message on the LCD.
Selecting a Function
To change any parameter, the appropriate function button must first be pushed. Once a function button is pushed, that button will remain illumi nated and the others will turn off to provide a reminder of which function is active.
Pushing a function button that has sub-functions under it will show the name of the function and the first menu choice. For example, pushing the
SDI function button will bring you to the top of the SDI menu, SDI: Select Channels
select the choices under this menu:
The selected choice will be surrounded by brackets < > indicating your choice. Once you reach the desired choice, press the menu. Depending on the sub-function chosen, either a further set of sub-functions or the current value of the function is displayed.

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.

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.

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.

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:
