L-BAND IN: Input BNC connector for L-band satellite signals. This connector can also carry
LNB power back to the satellite receiver (see section 5.1.1).
!
If LED7 is on or flashing, there will be DC voltage for LNB power at the L-BAND IN
connector. This can damage some test equipment.
You can turn off the LNB power by setting DIP switch 3 to the off position.
L-BAND (MONITORING) OUT: Monitoring output BNC is an L-Band RF output for monitoring of L-band
satellite signals.
FIBER OUTPUT: SC/PC, SC/APC, ST/PC or FC/PC female connector with the optical output from the
7707LT/LTA as shown in section 3.1.3. This connector should be connected to the
FIBER IN connector of a 7707LR module at the destination end with a suitable fiber
optic cable. The 7707LT/LTA transmits on the wavelength marked on the rear
panel.

2.3.4. Handling and Connecting Fibers
"
Never touch the end face of an optical fiber. Always keep dust caps on optical fiber
connectors when not connected and always remember to properly clean the optical
end facet of a connector before making a connection.
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 you maintain a minimum bending radius of 5 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. 7707LT/LTA STATUS INDICATORS
The 7707LT/LTA module has nine 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 seven small LEDs that indicate the status of the incoming RF signal, laser status, LNB power,
and AGC/manual operation.
RF HIGH: This red LED (LED1) will be on when the incoming RF signal is higher than the
permitted Input signal range.
RF OK: This green LED (LED2) will be on when the incoming RF signal is within the
permitted Input signal range.
RF LOW: This yellow LED (LED3) will be on when the incoming RF signal is lower than the
permitted Input signal range.
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.
LNB POWER: The LED (LED6) will be on yellow when there is LNB power (+13 or +17 volts DC)
being output on the RF input BNC (DIP switch 3 is on). Refer to section 5.1.1 for a
description of how to set the LNB power.
The LED (LED6) will be yellow and flashing on and off if LNB power is enabled and
there is a short on the RF cable connected to the RF input BNC. Remove the short
circuit from the cable and then reset the cable short via the card edge menu. The
LED should stay on if the short was removed.

AGC/ MANUAL: This green LED (LED7) is on when the card is operating in AGC mode. If the card
is set to AGC mode by setting DIP switch 4 to the Off position, the card will be in
AGC mode if the RF input level is within AGC range and this is indicated by LED7.
If the RF level drops out of AGC range, the card will be operating in manual 30dB
gain mode and LED7 will turn off.
To enable AGC mode, set DIP switch 4 to the Off position.
To disable AGC and set to manual mode, set DIP switch 4 to the On position
(towards PCB).
!
If the LNB POWER LED (LED6) is on or flashing, there will be DC voltage for LNB power
at the L-BAND IN connector. This can damage some test equipment.
You can turn off the LNB power by setting DIP switch 3 to the Off position.
"
If the LNB POWER LED (LED6) is flashing when the board is first plugged in, reset the
cable short option via card edge menu to reset the LNB power circuitry.
If the flashing continues, then the RF cable has a short.
4.2. 7707LR STATUS INDICATORS
The 7707LR modules have nine 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 RF signal, and optical input signal.
RF HIGH: This red LED (LED1) will be on when the output RF signal is higher than the rated
output signal range.
RF OK: This green LED (LED2) will be on when the output RF signal is within the rated
output signal range.
RF LOW: This yellow LED (LED3) will be on when the output RF signal is lower than the rated
output signal range.
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 than the rated
input range.
AGC/MANUAL: 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.
To disable AGC and set to manual mode, set DIP switch 4 to the On position
(towards PCB).
