7707IFTA/IFRA Series IF Fiber Transmitter / Receiver
Revision 4.1 7707IFTA/IFRA - 9
2.1. 7707IFTA CONNECTIONS
IF IN: Input BNC connector for IF satellite signals
IF OUT: Output BNC is an IF output for monitoring or further signal distribution of your IF
satellite signals.
FIBER OUTPUT: SC/PC, ST/PC or FC/PC female connector with the optical output from the
7707IFTA as shown in section 3.1.3. This connector should be connected to the
FIBER IN connector of a 7707IFRA module at the destination end with a suitable
fiber optic cable. The 7707IFTA transmits on the wavelength marked on the rear
panel.
2.2. 7707IFRA CONNECTIONS
FIBER INPUT: SC/PC, ST/PC or FC/PC female connector with the optical input to the 7707IFRA as
shown in section 2.7.2. This connector should be connected to the FIBER OUT
connector of a 7707IFTA module at the origination end with a suitable fiber optic
cable.
IF OUT: Two output BNC connectors for distributing IF satellite signals. The BNC nearest
the bottom of the rear panel is the primary output and will provide slightly better
performance than the secondary output located directly under the fiber optic input.
2.3. CARE AND HANDLING OF OPTICAL FIBER
2.3.1. Safety
!
Never look directly into an optical fiber. Non-reversible damage to the eye can occur
in a matter of milliseconds.
The laser modules used in the Evertz IF fiber optic modules are Class I, II, and III depending on the
required output wavelength.
2.3.2. Handling and Connecting Fibers
" Never touch the end face of an optical fiber.
The transmission characteristics of the fiber are dependent on the shape of the optical core and therefore
care must be taken to prevent fiber damage due to heavy objects or abrupt fiber bending. Evertz
recommends that the user maintains a minimum bending radius of 3 cm to avoid fiber-bending loss that
will decrease the maximum attainable distance of the fiber cable. The Evertz fiber optic modules come
with cable lockout devices, to prevent the user from damaging the fiber by installing a module into a slot in
the frame that does not have a suitable I/O module.

4. STATUS INDICATORS AND DISPLAYS
4.1. 7707IFTA STATUS INDICATORS
The 7707IFTA module has 9 LED Status indicators on the front card edge to show operational status of
the card at a glance.
Two large LEDs on the front of the board indicate the general health of the module.
LOCAL FAULT: This Red LED indicates poor module health and will be illuminated if a board power
fault exists (i.e.: a blown fuse) or if the laser is nearing the end of the life cycle. The
LOCAL FAULT indication can also be reported to the frame through the FRAME
STATUS jumper.
MODULE OK: This Green LED indicates good module health. It will be On when the board power
is good.
There are 7 small LEDs on the card edge. Six of which indicate the status of the incoming IF signal, laser
status, and AGC/manual operation.
IF HIGH: This red LED (LED1) will be On when the incoming IF signal is higher than the set
upper IF Threshold trip point.
IF OK: This green LED (LED2) will be On when the incoming IF signal is within the set
upper and lower IF Threshold trip points.
IF LOW: This yellow LED (LED3) will be On when the incoming IF signal is lower than the set
lower IF Threshold trip point.
LASER FAIL: This red LED (LED4) will be On when the laser is at the end of its life. This is a sign
that the laser should be replaced immediately.
LASER OK: This green LED (LED5) will be On when the output laser is operating with its normal
output power.
LED 6: The LED (LED6) is not used on this product.
AGC ON: This Green Led (LED 7) is On when AGC Mode is enabled and Off when Manual
mode is enabled. To enable AGC mode, set DIP switch 4 to the OFF position (away
from PCB). To disable AGC and set to manual mode, set DIP switch 4 to the ON

4.2. 7707IFRA STATUS INDICATORS
The 7707IFRA modules have 9 LED Status indicators on the front card edge to show operational status of
the card at a glance.
Two large LEDs on the front of the board indicate the general health of the module.
LOCAL FAULT: This Red LED indicates poor module health and will be On during the absence of a
valid optical input signal, or if a local input power fault exists (i.e. a blown fuse). The
LOCAL FAULT indication can also be reported to the frame through the FRAME
STATUS jumper.
MODULE OK: This Green LED indicates good module health. It will be On when a valid optical
input signal is present, and the board power is good.
There are 7 small LEDs that indicate the status of the output IF signal and optical input signal.
IF HIGH: This red LED (LED1) will be On when the output IF signal is higher than the set
upper IF output threshold trip level.
IF OK: This green LED (LED2) will be On when the output IF signal is within the set upper
and lower threshold trip levels.
IF LOW: This yellow LED (LED3) will be On when the output IF signal is lower than the set
lower IF output threshold trip level.
OPTICAL INPUT HIGH: This red LED (LED4) will be On when the input optical power is to high.
OPTICAL INPUT OK: This green LED (LED 5) will be On when the input optical power is within the
rated input range.
OPTICAL INPUT LOW: This yellow LED (LED6) will be On when the optical power is lower than the
rated input range.
AGC ON: This green (LED7) is on when AGC mode is enabled and Off when manual mode is
enabled. To enable AGC mode, set DIP switch 4 to the OFF position (away from
PCB). To disable AGC and set to manual mode, set DIP switch 4 to the ON
position (towards PCB).

5. DIP SWITCH CONTROLS
5.1. IFTA DIP SWITCH CONTROLS
The 7707IFTA modules are equipped with a 4 position DIP switch at the front card edge. All positions are
assigned sequentially such that switch 1 is located at the top of the DIP switch (farthest from the card
ejector). Table 5-1 gives an overview of the front DIP switch functions and section 2.6.1 describes the
front DIP switch function in more detail. The On (closed) position is down, or closest to the printed circuit
board. The Off (open) position is up, or farthest from the printed circuit board.

4 AGC Disable
Table 5-1: Front DIP Switch Functions
5.1.1. Configuring IFTA for AGC or Manual mode
The 7707IFTA input IF stage has an automatic gain control (AGC) that adjusts to varying input IF levels.
If the input IF level differs from –20dBm the AGC will adjust the level so that the level presented to the
optical link is maintained at –20dBm. To set the unit in AGC (Automatic Gain Control) mode, set Dip 4 to
the Off (away from PCB) position, conversely, to set the unit in Manual mode, set Dip 4 to the On (towards
PCB) position. Once the card has been set to Manual mode, the user can adjust the IF gain values
manually via the card edge menu system. See section 7.2.3.2. In AGC mode the monitor port will be
constant at –20dBm ±2dBm with input levels between –20 and –40dBm.
" NOTE: In order to conduct a frequency response sweep, the 7707IFA cards must
be set and configured to Manual Mode and not AGC mode.
5.2. IFRA DIP SWITCH CONTROLS
The 7707IFRA modules are equipped with a 4 position DIP switch at the front card edge. All positions are
assigned sequentially such that switch 1 is located at the top of the DIP switch (farthest from the card
ejector). The On (closed) position is down, or closest to the printed circuit board. The Off (open) position
is up, or farthest from the printed circuit board.

5.2.1. Configuring IFRA for AGC or Manual mode
The DIP switches control the gain of the IF output section of the 7707IFRA and can be used to adjust for
losses in varying lengths of fiber optic cable in the system. The 7707IFRA output IF stage has an
automatic gain control (AGC) that adjusts to varying input optical levels. To set the unit in AGC (Automatic
Gain Control) mode, set Dip 4 to the Off (away from PCB) position. To set the unit in Manual mode, set
Dip 4 to the On (towards PCB) position. Once the card has been set to Manual mode, the user can adjust
the gain values manually via the card edge menu system.
" In order to conduct a frequency response sweep, the 7707IFA cards must be set
and configured to Manual Mode and not AGC mode.
" Output IF power measurements are made with 1 m of fiber optic cable between the
transmitting module and the receiving module.

6.1.1. Selecting Whether Local Faults Will Be Monitored
By the Global Frame Status
The FRAME STATUS jumper J3 determines whether local faults (as shown by the Local Fault indicator)
will be connected to the 7700FR frame's global status bus.
FRAME STATUS: To monitor faults on this module with the frame status indicators (on the Power
Supply FRAME STATUS LED's and on the Frame's Fault Tally output) install this
jumper in the On position. (Default)
When this jumper is installed in the Off position local faults on this module will not
be monitored.
6.1.2. Selecting Whether Module Will Be Controlled From the Local Controls or Through the
VistaLINK
®
Interface
The MASTER jumper J38 selects whether the module will be controlled from the local user controls or
through the VistaLINK
®
interface.
MASTER: When this jumper is installed in the MASTER position, the card functions are
controlled through the local controls.
SLAVE: When this jumper is installed in the SLAVE position, the card functions are
controlled through the VistaLINK
®
interface.
6.1.3. Configuring the Module for Firmware Upgrades
UPGRADE: The UPGRADE jumper J43 is used when firmware upgrades are being done to the
module. For normal operation it should be installed in the RUN position. See the
Upgrading Firmware section of this manual for more information.
To upgrade the firmware in the module unit pull it out of the frame. Move the
UPGRADE jumper into the UPGD position. Install the Upgrade cable provided
(located in the vinyl pouch in the front of this manual) onto the SERIAL header at
the card edge. Re-install the module into the frame. Run the upgrade as described
in the Upgrading Firmware section of this manual. Once the upgrade is completed,
remove the module from the frame, move the UPGRADE jumper into the RUN
position, remove the upgrade cable and re-install the module. The module is now
ready for normal operation.

7. DOT-MATRIX DISPLAY
Additional signal and card status monitoring and control over the card’s parameters are provided via the 4-
digit alphanumeric display located on the card edge. The card edge toggle switch is used to select
whether the user is displaying status from the card (monitoring mode) or setting control parameters for the
card (control mode). To select one of the display modes, press the pushbutton one or more times to exit
the current display mode and return to the mode select menu item (the display will show MON or SET).
Press the toggle switch to select monitor mode (MON) or control mode (SET). Once the desired mode is
selected, press the pushbutton to enter that mode.
While in monitor mode, the toggle switch determines what data is being displayed on the alphanumeric
display. Each time the toggle switch is pressed up/down, the display advances to the next/previous
display. A message indicating what display mode is active is shown for one second. After one second
without the toggle switch being pressed, the selected display data is shown. The card edge pushbutton is
used to select sub-items where applicable.
7.1. CARD EDGE MENU SYSTEM
" When changes are made in the menu system, the user must exit the menu system
and wait 30 seconds before the new menu settings are stored in the flash memory.
7.1.1. Navigating the Menu System
While in control mode, the toggle switch and pushbutton are used to navigate through a menu system to
set various parameters for the module. To enter the menu system, press the pushbutton one or more
times to exit the current display mode and return to the mode select menu item. The display will show MON
or SET. Press the toggle switch to select control mode (SET) and then press the pushbutton to enter the
control mode main setup menu. Use the toggle switch to move up and down the list of available sub
menus. Once the desired submenu name is displayed, press the pushbutton to select the next menu
level.
In the sub menu there will be a list of parameters to adjust. To adjust any parameter, use the toggle
switch to move up or down to the desired parameter and press the pushbutton. Using the toggle switch,
adjust the parameter to its desired value. If the parameter is a numerical value, the number will increase if
toggle switch is pushed upward and the number will decrease if the toggle switch is pressed downward. If
the parameter contains a list of choices, the user can cycle through the list by pressing the toggle switch in
either direction.
When desired value is reached, depress the pushbutton. This will update the parameter to the selected
value and return to the mode select menu item (the display shows SET). To change another parameter,
press the pushbutton to enter the main menu system again and continue selecting and adjusting other
parameters.
Each time the toggle switch is pressed up/down, the display advances to the next/previous display. A
message indicating what display mode is active is shown for one second. After one second without the
toggle switch being pressed, the selected display data is shown. The card edge pushbutton is used to
select sub-items where applicable.
