Power Status
screen for the FRX differs from the FTX in that only
MAIN PWR
is shown. An
example of the FRX Power Status screen is shown below:
The
Link Status
screen for the FRX differs from that of the FTX in that instead of laser
current and status, effective link gain is displayed as
INPUT
, along with received
RF SIG
nal
STATUS
. Sufficient link gain from FTX to FRX is needed for good RF signal integrity. As with
the other status screens, parameters in spec will be shown in green, otherwise they will be
red. Below are some examples of displays where both the link gain and RF output signal
integrity are good; where the link gain has degraded but not yet to the point where RF output
signal integrity is impaired; and finally an example where link gain has degraded to the point
where RF output signal integrity is impaired. Link gain should be between -8 to +9dB.
INSTALLATION
The SL2150 Series operates from 85 to 240 VAC with the included wall-mount 12V power
supply or other source in a range from 9 to 24 VDC and at least 10W of power. It uses a
coaxial type connector (sleeve ground) on the rear panel labeled
POWER
. If desired, the
units can be powered from a battery pack or automotive battery instead of the wall unit.
If the dish uses LNB power, it should be connected to
RF-IN
before power is applied to the
FTX. Otherwise, hot-plugging the dish to
RF-IN
may cause the power supply overcurrent
protection to trip, and a fault condition to occur as evidenced by the
POWER
LED flashing
red. If this happens, remove power to FTX and try again after a few minutes. Once the dish is
connected to
RF-IN
, the SL2150 Series does not have any special sequencing requirements
for connection of fiber,
RF-OUT
, or power. RG58/59 or other 50/75 ohm coax cable must be
used for the RF inputs and outputs, and single mode fiber with the proper APC connectors
must be used for the fiber link. Multimode fiber cannot be used reliably with the SL2150
series. The SL2150 Series come standard as stand-alone units. An optional rack-mounting
kit is available to mount up to 3 units in a 1 Rack-unit or 1 ¾” by 19” rack space. The part
number is –RMT.
