Environmental Conditions
The device is designed for indoor use and for an ambient temperature range.
Mechanical Integration
It is not permitted to fix the chassis on the rack mount flanges, only. Balanced
weight distribution of the chassis has to be ensured by placing it on a solid surface
or by using rack rails.
Sufficient airflow through the chassis must be ensured to achieve best cooling
results. Do not block or obstruct the airflow through the chassis at the front and at
the rear side, e.g. by placing large components close to the rear side.
Grounding, AC Connection, Cables
To minimize shock hazard the device must be connected to an electrical ground via
a ground wire, please refer to chapter 4.2.2. For the AC connection, the device
must be connected to the AC power supply mains through two power cables with
three conductors and with the ground wire firmly connected to an electrical ground
(safety ground) at the power outlet. Any interruption of the protective ground con-
ductor will cause a potential shock hazard that might cause personal injury.
Risk of electrical shock and energy hazard:
Disconnecting a single power supply line only does not interrupt the AC supply of
the device. To isolate the device completely, disconnect both power supply lines.
Do not connect the device to mains supply exceeding the specifications for input
voltage and frequency. The recommended AC cables to be applied are standard
high temperature power cables with type IEC 60320-C13 appliance plug appro-
priately rated to the conditions of the country where the device is operated.

The DEV 2182/zz (DEV 2185/zz) is a distribution amplifier providing one input port
and eight (sixteen) output ports. The DEV 2183/zz is a dual distribution amplifier
with two input ports and two times eight output ports. The "zz" indicates that all
distribution amplifiers are available with 50 Ohm or 75 Ohm input ports and with
50 Ohm or 75 Ohm output ports. All 50 Ohm ports are realized with female SMA
connectors and for 75 Ohm ports female precision F connectors are applied.
All products provide redundant power supplies; and -for each channel- a moni-
toring output port, RF level monitoring functionality, and an LNB power supply with
current monitoring.
3.1 Product Structure
A distribution amplifier is designed as follows: The incoming signal is routed
through the LNB power supply to the connector labeled "Source" at the front side of
the chassis (please refer to the first illustration of chapter 3.2.1). The input
connector to the amplifier labeled "Amp In" is located there as well. A short external
cable bridge connects the (DC blocked) input signal routed through the LNB power
supply and the input to the amplifier. After the amplifier, the monitoring path is
coupled out (connector labeled "Monitor" at the front side) and the signal is split into
two outputs which can feed a 1:8 passive splitter, each. The second output is
terminated internally if it is not used (DEV 2182/zz, DEV 2183/zz).
The structure of the different products is shown in the block diagrams below.

3.2 Device Panel
3.2.1 Distribution Amplifier with Control Port
The products are equipped with one (DEV 2182, DEV 2185) or two (DEV 2183)
distribution amplifiers providing the following elements at the front side:
RF
LNB Power Source Monitor Amp In
1 2 3 4 5 6
Usually (not shown in the figures) the distribution amplifier is operated with the
cable bridge DEV 73-0007 which is installed between the SMA ports labeled "Source"
((6), input signal routed through the LNB power supply) and "Amp In" ((2), input to
the amplifier). If the cable bridge is removed, this permits to directly access the
output of the inline amplifier or of the LNB connected to the input port of the
distribution amplifier (located at the rear side of the chassis) which is (or can be)
supplied by the LNB power supply of the distribution amplifier.
Additionally, an SMA port labeled "Monitor" (1) is available for signal monitoring,
providing an RF signal at the same level as the input signal.
The "LNB Power" push button (5) is used to turn on or to turn off the LNB power
supply. A ballpoint pen is recommended to operate the push button.
The LNB power status is indicated via the "LNB Power" LED (4): If the LNB power
supply is turned off, the LED is off. If the LNB power supply is turned on and if a
current is fed to the input of the distribution amplifier which is within a certain
adjustable range (i.e. the current monitoring interval), the LED is green. If the LED is
red, the current delivered by the LNB power supply is out of range, i.e. the red LED
signalizes an alarm which is indicated in parallel via potential free contacts at the
alarm connector (please refer to chapter 6.1.2).
With the RF level monitoring functionality of the distribution amplifier the
aggregated signal power level of the RF signal is measured and compared with an
RF threshold level. The status is signalized via the "RF" LED (3): Green means that
the signal level is above the threshold; red signalizes an alarm (i.e. the signal level is
below the threshold), which is indicated in parallel via potential free contacts at the
alarm connector (chapter 6.1.2).
Each distribution amplifier provides a control port realized as a serial interface
permitting the adjustment of the current monitoring interval and the adjustment of
the RF threshold level (chapter 4.5). The next figure shows the serial interface
connector (7) of a DEV 2182/zz or of a DEV 2185/zz:

Three LEDs located at the device panel on the right are signalizing the power supply
operating status of the device:
"Power Supply 1" LED ((8), green) and "Power Supply 2" LED ((9), green):
The related power supply unit provides secondary voltage if this LED is on.
"Failure" LED ((10), red): This LED is on if either power supply unit does not
deliver any secondary voltage. The reason for this can be a defective power
supply, a defective primary protection fuse, or a missing primary voltage.

4.2.3 Connection of RF Signal Cables
Apply strain relieves to the external RF signal cables which are to be connected in a
way, that the connectors of the device are not stressed mechanically.
If the DEV 218x is powered up already and before the RF cables are to be
connected to the chassis, the LNB power of the distribution amplifier(s) is to be
turned off! Otherwise there is a risk that a high impulse current degrades the RF
performance of the (corresponding) input connector.
The product is delivered with the DEV 73-0007 cable bridge(s) already installed. If
not installed, it is recommended to apply the cable bridge(s) first.
Then, connect the RF input cable(s) (e.g. from the LNB) to the related input port(s);
finally connect the RF output cables (to the signal receivers) to the output ports.
When connecting RF cables to the chassis, each connector is to be tightened with a
torque wrench. For 75 Ohm F connectors the applied torque should not exceed
4.5 Nm (39.8 lbf-in). In case of 50 Ohm SMA connectors, a torque wrench adjusted
to 1 Nm (8.85 lbf-in) is to be used.
Note:
For 75 Ohm RF connectors, female precision F connectors are applied. Make
sure, that the applied connectors are precision F connectors (with thin inner
conductor).
Each unused output port has to be terminated with an appropriate load to
achieve best amplitude frequency response.
Best signal quality is achieved by connecting the signal receivers symmetrically
to the output ports:
•1…4 and 5…8 of the (each) 1:8 splitter (DEV 2182/zz, DEV 2183/zz);
•1…4, 5…8, 9…12, and 13…16 of the 1:16 splitter (DEV 2185/zz);
and by connecting impedance matched loads to the unused ports.
If all cables are connected, the device can be powered up.
Now LNB power can be turned on for the distribution amplifier(s) which is (are)
required to feed power to an LNB.
4.3 Device Factory Settings
The distribution amplifiers provide RF level monitoring functionality, i.e. the
aggregated signal power level of the RF signal is measured and compared with an
RF threshold level. If the signal level is below the threshold level, an alarm is
triggered which is indicated via LED (please refer to chapter 3.2.1) and via the
alarm connector (chapter 6.1.2). The factory setting for the RF threshold level is:
RF Threshold Level: -40 dBm
The RF threshold level can be adjusted (chapter 4.5).
The distribution amplifiers are capable of providing LNB power at the RF input port.
With the current monitoring functionality, the delivered current is monitored. If the
measured current exceeds the defined interval, an alarm is generated indicated via
LED (chapter 3.2.1) and via alarm connector (chapter 6.1.2). The factory settings for
the current monitoring interval are:
Lower Limit: 100 mA
Upper Limit: 350 mA
The lower limit and the upper limit of the current monitoring interval can be
adjusted (chapter 4.5).

4.4 Communication Interface Configuration
Per distribution amplifier a serial interface is provided as the communication
interface. The serial interface -requiring a standard terminal application, only- is
used for the setup of the RF threshold level and for the setup of the current
monitoring interval.
The Sub-D 9 pos female connector(s) labeled "Control" for the standard (3 wire)
RS 232 interface(s) is (are) located at the device panel (please refer to chapter
3.2.1); the pin assignment is stated in chapter 7.
The serial interface configuration is described by the following parameters:
Transmission rate: 9600
Data bits: 8
Parity check: none
Start/Stop bit: 1
Handshake: none
4.5 Setup via the Serial Interface
4.5.1 Start of the Configuration Program
To access the configuration program of a distribution amplifier, establish a hard-
ware connection between a serial port of a PC (e.g. COM1) and the (corresponding)
"Control" connector at the device panel using a straight cable; please refer to
chapter 7 for the pin assignment of the serial connector.
Next, start a terminal application (e.g. MS Windows HyperTerminal) on your PC.
If the terminal application was started and connected before the device was
powered up, the start-up info is displayed:
42-0230 ** Sat ZF Amplifier
B.01 ** Jun 29 2011 13:54:37
System Values lowlim meas. highlim
Bias on [mA]: 150.0 173.1 350.0
RFSense [dB]: -40.0 -24.7
press '?' for help
>
Depending on the type of the installed distribution amplifier, the identification
string (42-0230 ** Sat ZF Amplifier) and the firmware revision and date string
(B.01 ** Jun 29 2011 13:54:37) in the start-up info may vary.
The table below the identification string and the firmware revision and date string
consists of three lines only; in the example above the status and the measurement
of the "System Values" (Bias (LNB power supply) and RFSense (RF level) in the first
column) are shown. Note, that here Bias on is displayed here, since the LNB power
supply is turned on, otherwise Bias off appears instead. The second column
"lowlim" shows the applied lower limit for the current monitoring interval (here:
150.0 mA) and the applied RF threshold level (here: -40.0 dBm). The third column
"meas." shows the measured values for the current monitoring (here: 173.1 mA)
and for the RF level (here: -24.7 dBm). The forth column "highlim" shows the
applied upper limit for the current monitoring interval (here: 350.0 mA), only.
Note:
The interface settings of the terminal application have to match the serial
interface settings as described in chapter 4.4, otherwise it is not possible to
communicate with the configuration program.

The start-up info is not displayed if the terminal application was started and
connected after the device was powered up. Hitting any key on the keyboard
should cause a response of the configuration program followed by a prompt
character (">") indicating that the configuration program is ready for executing
the next command or input.
If there is no prompt visible or no response to an input, please check the serial
interface connection and the settings of the terminal application.
Valid commands or inputs for the configuration program are not echoed.
In this context and for better comprehension, commands or inputs are
indicated via bold courier letters.
4.5.2 Operation of the Configuration Program
In the following, the commands are presented which can be executed with the
configuration program.
4.5.2.1 Configuration Program Commands
Typing the question mark character ("?") lists the available commands:
>?
?: this help
select limit input for
r: RF Sense
b: Bias low
B: Bias high
s: save
q: quit without saving
d: display values

"?": output of the help text above;
"r": command for the modification of the RF threshold level
(please refer to chapter 4.5.2.2);
"b": command for the modification of the lower limit of the current monitoring
interval (chapter 4.5.2.3);
"B": command for the modification of the upper limit of the current monitoring
interval (chapter 4.5.2.3);
"s": command for applying and storing the changes made for the RF threshold level
setting and/or for the current monitoring interval settings;
"q": command for discarding changes made for the RF threshold level setting and/or
for the current monitoring interval settings (i.e. the values of the last "s"
command are still valid);
"d": monitoring command which returns the table informing about the current
settings and the measured values (equivalent to the table of the start-up info as
stated in chapter 4.5.1), e.g.
System Values lowlim meas. highlim

4.5.2.2 Modification of the RF Threshold Level
The modification of the RF threshold level is performed in two steps.
After the "r" command was entered, the configuration program responds:
>r
change RF Low Limit via "p"lus or "m"inus
>
By entering the (lower case) "p" (or the (capital) "P" or the "+") character, the value
is increased in steps of 1.0 dB:
>p-39.0
>+-38.0
>P-37.0
>
Or, by entering the (lower case) "m" (or the (capital) "M" or the "-") character, the
value is decreased in steps of 1.0 dB:
>m-38.0
>M-39.0
>--40.0
>
The second step is to store the value(s) by issuing the "s" command, which is
responded by the configuration program with:
>svalues saved
>
If changes on the value(s) are not to be saved and for retrieving the saved settings,
the "q" command is to be entered instead, which results in the response:
>qdiscarding input
>
Note:
It is possible, to alter more than one setting (i.e. the RF threshold level plus one
or both limits of the current monitoring interval) before saving or discarding
the changes.
Inputs to the configuration program are not echoed, only here they are
indicated for better comprehension.

4.5.2.3 Modification of the Current Monitoring Interval
The modification of the lower limit or of the upper limit of the current monitoring
interval is performed in two steps.
After the (lower case) "b" command (for the lower limit) was entered, the
configuration program responds:
>b
change Bias Low Limit via +/-
>
Or, to change the upper limit, enter the (capital) "B" command which returns:
>B
change Bias High Limit via +/-
>
In both cases, by entering the "+" (or the (lower case) "p" or the (capital) "P")
character, the value is increased in steps of 10.0 mA:
>+360.0
>p370.0
>P380.0
>
Or, by entering the "-" (or the (lower case) "m" or the (capital) "M") character, the
value is decreased in steps of 10.0 mA:
>-370.0
>M360.0
>m350.0
>
The second step is to store the value(s) by issuing the "s" command, which is
responded by the configuration program with:
>svalues saved
>
If changes on the value(s) are not to be saved and for retrieving the saved settings,
the "q" command is to be entered instead, which results in the response:
>qdiscarding input
>
Note:
It is possible, to alter more than one setting (i.e. one or both limits of the
current monitoring interval plus the RF threshold level) before saving or dis-
carding the changes.
It is recommended to select both limits of the current monitoring interval in a
way, that their values are not too close to the nominal current consumption of
the sink(s) to avoid frequent alarms due to variations in the current consump-
tion of the sink and due to the measurement accuracy of the distribution
amplifier.
Again, inputs to the configuration program are not echoed, only here they are
indicated for better comprehension.

monitoring interval via the serial interface.
6Error Indication
The indication of an error (i.e. an alarm) is realized via hardware, i.e. via red LEDs
(please refer to chapter 3.2) and via the alarm connector.
6.1 Error Indication via the Alarm Connector
The potential free contacts of the alarm connector located at the rear side provide
the following functionality (for the pin assignment, please refer to chapter 7):
6.1.1 A/B Alarm
A/B-Alarm signalizes that one or all power supplies do not deliver secondary power.
B-Alarm signalizes that one power supply unit does not deliver secondary power,
and A-Alarm signalizes that no power supply delivers secondary power.

6.1.2 Amplifier Alarm
The amplifier alarm is available (once or twice) at the alarm connector for remote
detection. The amplifier alarm indicates:
that the RF signal level was detected to be below the RF threshold level; or
that the current delivered by the LNB power supply was detected not to be
within the current monitoring interval; or
that both alarms are active (logical OR).
Note, that the amplifier alarm is active as well if the amplifier is not supplied with
power, i.e. either due to a power supply fail or if the device is powered off.
