Overview


The Digisat III is designed to be an aid in aligning satellite antennas so that they can provide maximum performance. Please be aware of the fact that there are numerous satellites which will cause the Digisat III to respond with a signal reading. The installer must select the correct satellite for alignment. It is quite easy to select the wrong satellite and find that the satellite receiver indicates "No Signal". The software provided with the satellite receiver can provide the elevation and azimuth of the satellite desired. With this information in-hand and a good compass you can point the antenna in the proper direction. Then, with the aid of the Digisat III , the performance of the antenna can be maximized by watching the tuning bar and digital strength readings. Please take time to read this instruction manual so you will be familiar with the capabilities of the Digisat III.

The Digisat III can be connected directly to the Phase III LNBF , DishPro dual or quad. It also can be connected directly to any standard LNBF.
The Digisat III can be powered by your satellite receiver or by connecting it to an optional battery. If you have a satellite receiver connected, the Digisat III will default to the power "ON" state. If you are using a battery pack for power, you must press the "ON/MENU" button to turn the Digisat III on. You can have both the battery and the satellite receiver plugged in simultaneously without damage. We offer an optional battery pack or you can use a pack like in a cell phone as long as the center pin of the input jack is center pin positive (+)and it supplies no more than 18 vDC.


Startup

Connect the satellite receiver or (optional) battery to the Digisat III. If you have connected a satellite receiver, the Digisat III will power up automatically, If you are using a battery, press the "ON/MENU" button. The Digisat III is immediately ready to begin antenna alignment.

Press to use the optional battery


When the meter is turned on and connected to a dish, the signal strength will be indicated by the bar graph and in digits just above the bar graph. As you move the dish, you will see an increase and decrease in signal strength. The objective is to maximize the signal strength indicated by minor azimuth, elevation and rotation adjustments of the dish. When you have maximized the signal, lock the dish mount bolts and re-attach the LNBF to the switches or cables connecting the satellite receiver to the antenna. Then check your alignment efforts with the satellite receiver.


Connections

Single or Dual LNBFs

Connect the Digisat III to a single or a dual LNBF with the provided RG-6 jumper cable. It does not matter which connection on a dual LNBF you use, both connectors supply the same information about alignment.
 

Satfinder digital perfectvision 10 Digisat III pro LCD Satellite Tracking Meter Manual.


Phase III LNBF
Connect the provided RG-6 jumper to any of the four 'F' connections on the Phase III LNBF, these connections are not satellite-specific and all four provide the same information. The Digisat III will provide alignment data from the 101° LNBF immediately. If you would like to look at the 19° LNBF, turn "on" the 22K tone. See page 3 of this manual for an explanation of this feature. IF you use a satellite receiver for power, understand that a satellite receiver will typically send voltage switch and 22K tones to the LNBF when in a 'search' mode. The 22K tone from the receiver will cause the Phase III LNBF to jump from the 101° feed to the 119° satellite feed. That can be confusing while trying to line up a dish. So, to avoid this problem, block the tones from the receiver by selecting >OFF in the 22KHZ MODE menu; then the 101° signal will be continuously presented on the meter. IF you want to look at the 119° satellite, simply select >ON in the 22KHZ MODE menu and the Digisat will send a continuous self-generated tone which will lock the LNBF on the 119° feed .


Audible Tone

An audible tone is available if you would prefer listening to the Digisat III rather than trying to watch the digital readings or bar graph.
To use the tone capability, start from the default signal sensing mode. (Right)

Press the "OFF/DOWN" button once. The tone will begin and the letter 'T' will appear above the bar graph.
To cancel the tone, press the "OFF/DOWN" button one more time.


The Menu

 
The Digisat III can provide a lot of information about your satellite system. To access the main menu, press the "ON/MENU" button. The screen illustrated (right) will appear and provide a very detailed range of tests and adjustments. The menu map and illustrations about what " each function can do for you are in this manual. Press the "UP" or "OFF/DOWN" button to scroll the arrowhead pointer up and down through the menu items listed below.

VIEW SIGNAL

This is the screen you will see when you first turn the Digisat III on. The bar indicates the general signal strength of the LNBF, the strength listed as a digital number, the voltage provided from the satellite receiver (or battery) and the amp draw of all connected devices shown in mA.


VIEW RECEIVER

Displays the voltage provided by the satellite receiver or battery. Indicates the total current draw in mA of all connected components. Also indicates if a 22kHz tone is being sent by a DirecTV® receiver. These readings verify the receiver operation.Also, using the receiver for power, you can measure voltage at the receiver and then at the end of the coax, this will help calculate the voltage loss through the coax cable. Pressing the "OFF/DOWN" button brings up a second screen which displays the requested port number from an early model DishNetwork receiver.


22KHZ MODE

The Digisat III has a built-in 22Khz tone generator which can be activated by this function thereby allowing you to control many typical switches such as the DirecTV Phase III. This feature is handy as you can look at the 119° satellite if the 22KHZ tone is "ON" or look at the 101° satellite on the same port if the If the 22KHZ is "OFF". Also, the tone from a DirecTV receiver and the switch commands from a DishPro® receiver can be blocked if the 22KHZ MODE is selected and set to >OFF. The text "OFF" will appear below the strength bar.
 

NEW DISH CTRL

This feature allows you to control the DishPro switches. Specifically, Port 1, 2 and 3 on the DP34, or Port 1 and 2 on the DP21 can be selected as needed. Scroll down to >NEW DISH CTRL in the Digisat III menu and press the "ON/MENU" button. Select one of the three Ports and press "ON/MENU" again. The Port switch command will be sent from the Digisat III. See pages 5 and 6 for more information about this feature.
 

ATTEN

The attenuate item is hidden from view, you must press the "OFF/DOWN" button to scroll
down to it. This attenuates (reduces) the signal meter reading to lower numbers. Handy if the bar graph is maxed out. Note that the 'A' text is displayed when this feature is turned on. To turn this feature off, go back to >ATTEN and select >OFF.
 

SETUP

Setup takes you to a list of options as follows:
MAX HOLD This function superimposes a small bar at the end of the bar graph (signal strength) which keeps track of the maximum signal received. This can be turned on or off as needed. Your choice will remain in the memory.
LCD-CONTRAST Scroll down to "DARKER" or "LIGHTER", then press the "ON/MENU"
button repeatedly to darken or lighten graphics. Scroll back up to >EXIT and press the "ON/MENU" button to save your selection in the memory.
AUTO OFF This sets the automatic timer to turn the Digisat III off when the battery is used for power. Scroll down to the setting you prefer and press the "ON/MENU" button to save the time you selected in the memory.

You can check the video present at the satellite receiver with the Digisat III in the line. Just remember that the switching signals from the receiver can be blocked if you have the 22K MODE set to "OFF". To allow the receiver to properly control any attached switches or the LNBF, make sure the selection in 22K MODE is ">RECEIVER".


 

DishNetwork Info


Either the optional battery pack or a DP receiver can be used to power the Digisat as shown in the following setups on this page. If you use the optional battery, make sure it is fully charged as the Port selection in "NEW DISH CTRL" may not work reliably with a low battery. If you do not have the optional battery, use the DP receiver to power the Digisat .
 
Note that the DP receiver sends out a "switch" command whenever it is not locked on a satellite, obviously, this is the case if the antenna is not aligned yet. This command causes the dual or quad LNBF to switch randomly from one output (say 110) to the other (say 119). When aligning the antenna, this can be pretty confusing so block the switch command in the Digisat III by turning the 22KHZ MODE to ">OFF" when a dual or quad LNBF is attached and a DP receiver is used for power.

The DP21 Switch


If you have the optional battery pack please note that the DP21 switch and the connected LNBFs draw more current than the battery can provide on a continuing basis; therefore, we suggest that you attach a DP receiver to the Digisat III. The receiver will then supply the necessary constant power to the components.

The DP34 Switch

The DP34 and its components draw a considerable amount of current, typically in excess of 600 mA. Since this approaches the upper current limit of the Digisat III, we suggest using two DP receivers, one to power the hardware components and the second (or the optional battery) to power the Digisat III.
You can look at any of the three switch ports by making the appropriate PORT selection in the Digisat III menu. The port selection signal generated in the Digisat III is only sent when you initially select Port 1 or Port 2 or Port 3 with the arrowhead and press the "ON/MENU" button. Thereafter, if you power down the switch, or make any other changes, you may need to re-select the desired port in the menu and press the "ON/MENU" button again.

F.A.Q.s
Digisat III

 
Be aware of the fact that the Digisat III is an AID to aligning the antenna, it does not identify which satellite you are looking at. It still takes basic knowledge of satellite elevation and azimuth to track and identify the correct satellite(s). You can easily pick the wrong satellite, align the antenna and then discover that the satellite receiver indicates NO SIGNAL.

The Digisat III can be used with digital or analog LNBFs. It also operates with both circular and linear polarized LNBFs. The only qualification is that the LNBF must be down-converting to an I.F. Frequency of 900~2200 Mhz (which is typical of most LNBFs).
 
The Digisat III looks at the entire spectrum of signals received from the LNBF and gives an overall summation of the signal. It is not transponder / frequency selectable. IF you need specific frequency selections, Perfect 10 offers the 'SatLook Digital' meter which can provide individual transponder information.
 
There is not an exact number meter reading which you should attempt to achieve. Your objective is to MAXIMIZE the meter reading so that the antenna and LNBF is providing the best signal possible.
 
The signal level reading indicated on the Digisat III will NOT be the same reading as you get on the satellite receiver. These two readings can compliment each other (when one increases, the other increases) but the numbers will not be the same. The sat receiver indicates interpreted data reception (Forward Error Correction) while the Digisat III indicates overall gain of the LNBFs.
 
The Digisat III can be confused by weak (satellite frequency) signals originating from the LNBF if these weak signals strike a tree or building and are reflected back into the dish. When trees are in the path of the satellite signals, you may need to fall back on the satellite receiver for correct dish alignment.
 
If you purchased the optional battery pack, note that battery performance time is GREATLY affected by cold air temperature, this is just a fact of life for batteries. In freezing conditions battery packs can lose more than 60% of their capacity. To avoid cold battery problems, keep the Digisat III in your (inside) shirt pocket until time to use it.
 
Some LNBF switches can interfere with proper operation of this device. The Digisat III is designed to control DirecTV and DishPro devices. Switches that require other methods of switch selection may have to be bypassed. Some antennas have these devices located in the mounting area of the LNBFs. To alleviate this situation, it may be necessary to carry an extra mounting bracket with standard LNBFs. Temporarily utilize this extra bracket until alignment is completed, then reattach the switched LNBFs.
 
The Digisat III is designed to align satellite antennas. It will not aid in the alignment of off-air TV antennas.
 
If you presently own an early model Digisat Plus with a battery pack, you can use the same battery to power the Digisat III unit also.
 
The Digisat III is warranted for one full year against manufacturing defects. We will ask for proof of purchase so KEEP YOUR RECEIPT or keep track of the invoice number.
