Introduction  
Overall Description  
The SMP Software along with the QSB-1 and FM-1 allow a  
user to easily manage large systems of BTR-1 base stations  
along with their beltpacks.  
The QSB-1 (Qard Serial Bus) pod interfaces with the SMP via  
a USB connection to the computer. This enables the user to  
download events into a small, convenient, DataFlash® card.  
FM-1 "Snap Shots" can also be uploaded to the SMP from the  
DataFlash® card via the QSB-1.  
The SMP (System Manager Program) software enables a user  
to set-up multiple events on the computer. An event is a partic-  
ular situation where a pack of ten base stations need their pa-  
rameter set a certain way. These parameters include transmit  
and receive frequencies, intercom levels, auxiliary levels, to  
name a few. The event could be a football game or act one of a  
broadway show, the possible applications are endless. A good  
example is a college football team which uses a ten pack  
BTR-1 system for its’ coaches on the field to talk to each other  
and the personal in the press box. If that team plays twelve  
games a year and six of them are away then the SMP could be  
used to set up 7 events. Event one would be the frequencies  
and parameters for a ten pack of base stations used at home.  
The other six events would be the ten pack’s frequencies and  
parameters for the away locations.  
The FM-1 (Frequency Manager) interfaces with up to ten  
BTR-1 base stations. The FM-1 talks to the bases via a CAN  
bus system. The CAN bus starts at the FM-1 and daisy chains  
through all the base stations and then back to the FM-1 to ter-  
minate. The DataFlash® card is inserted in the card reader  
slot for the FM-1 to read events from the card. With the  
DataFlash® card in the FM-1 the user can select an event on  
the card and download the selected event. Now the user can  
download the event into the base stations. The FM-1 can also  
take “snap shots”of the ten pack of bases and download those  
parameters on the DataFlash® card for eventually uploading  
into the SMP.

Frequencies:  
Allow the user to paste frequencies only  
into an event from a tab delimited text  
file. For example, Microsoft® Excel can  
be used as a source to transfer frequen-  
cies to the SMP. The 1st column of 10  
rows in Excel can be base TX frequen-  
cies and the 2nd column of 10 rows can  
be the RX frequencies. This 2 x 10 array  
of numbers is then selected and copied to  
the clip board. Now "Paste Frequencies"  
may be used to paste the 2 x 10 array of  
frequencies to the SMP. The frequencies  
of the base stations read from the file  
must be within the bands set for the  
bases in the SMP.

identical. The C button was chosen to display below because it  
has a few more additional options. If the intercom type chosen  
is "four wire" the button tabs are replaced by a single "four  
wire" tab. The operation of it's features are similar to that be-

Downloading / Uploading  
After an event is set-up it may be downloaded to a  
DataFlash® card for the eventual downloading into a FM-1  
and thus to a system of up to 10 base stations.  
A snap shot of a system of up to 10 base stations may also be  
uploaded to the SMP in order to examine the settings of the  
system for trouble-shooting, use the system as a ‘base line” for  
setting up other events, or just for records.

The input to the FM-1 is a standard IEC connector. It accepts  
100 – 240 VAC, 50 – 60 Hz.  
If the unit has been connected to AC power for some time, and  
the front panel switch is turned on, the unit will power-up al-  
most instantaneously. However, if the unit has its’ power  
switch in the on position and is then powered by VAC voltage  
via the rear panel the unit will take 3 to 4 seconds to  
power-up. This is normal, the internal power supply of the  
FM-1 takes 3 to 4 second to power up if powered-up cold.

Operation  
Basic Description  
The FM-1 (Frequency Manager) interfaces with up to ten  
BTR-1 base stations. The FM-1 talks to the bases via a CAN  
bus system. The CAN bus starts at the FM-1 and daisy chains  
through all the base stations and then back to the FM-1 to ter-  
minate. The flash card is inserted in the card reader slot for the  
FM-1 to read events from the card. With the flash card in the  
FM-1 the user can select an event on the card and download  
the selected event. Now the user can download the event into  
the base stations. The FM-1 can also take “snap shots” of the  
ten pack of bases and download those parameters on the flash  
card for eventually uploading into the SMP.  
The lower left-hand corner contains the software version in  
the FM-1. After the start-up screen the event screen will be  
displayed. The event screen is the main default screen. It will  
display the current event in FM-1 memory. Up to 99 events  
may be stored in the FM-1 and on a card, see the "FM-1 Menu  
Flow Chart section for the menu structure.  
Connecting the FM-1 to the Base Stations  
The FM-1 communicates to the base stations via the CAN bus.  
This CAN bus starts at the FM-1 “OUT” port. It is connected  
from there to the first base station. It does not matter which  
CAN bus base station jack is the input or output. From the  
first base it daisy chains through all the base stations (up to  
ten). The CAN bus connects from the last base station to the  
FM-1 port marked “Termination”.

Downloading a Card  
The following steps download a card to the FM-1.  
After programming the display will indicate the following:  
1. From the event screen press <MENU> once to arrive at  
the download card / select event menu screen.  
Normal Numbers = The BTR-1 were programmed to the  
parameters downloaded.  
2. Select download card with the <UP>/<DOWN> arrow  
buttons and press <SET> to go to the download screen.  
Inverted Numbers = Programming of the base cannot be  
confirmed.  
3.  
Make sure the DataFlash® card is in the FM-1 and  
press <SET>. The unit will indicate it is downloading  
from the card.  
Snap Shot  
The FM-1 can take snap shots of the base station connected to  
its’ CAN bus. This is a record of the base station’s frequencies  
and settings at the time the snap shot is taken.  
4. The FM-1 will say it has completed the download. Af-  
ter a few seconds it will now go to the event screen.  
The <MENU> button could also be pressed to proceed  
to the event screen.  
1. From the event screen press <Snap Shot> for about 2  
seconds. The following screen will occur. Make sure  
there is a DataFlash® in the FM-1.  
The contents on the DataFlash® card write over all previous  
FM-1 memory.  
Selecting an Event and Downloading to  
System  
The following steps select an event that has been downloaded  
from a DataFlash® card to the FM-1. Then that event is  
downloaded to the BTR-1s on the CAN bus.  
2.  
Press <SET> to take the snap shot.  
1. From the event screen press <MENU> once to arrive at  
the download card / select event menu screen.  
A snap shot is saved to the DataFlash® card. If the snap shot  
is successful, the confirmation screen displays, then defaults to  
the event screen.  
2. Select “select event” with the <UP>/<DOWN> arrow  
keys and press <SET> to go to the select event screen.  
3. The last event in FM-1 memory will be displayed.  
Press <SET> and the current events in memory will be  
displayed. The event will begin flashing.  
Up to 10 snap shots may be placed on a DataFlash® card.  
4. Use the <UP>/<DOWN> arrows to select the event de-  
sired. Press <SET> at the displayed event to enter the  
system download screen.  
5. Press <SET> again at the above screen to send the  
event to the system of BTR-1 base stations.  
6. After programmed, press <MENU> to arrive back at  
the event screen.  
As the BTR-1s are programmed and confirmed the numbers  
displayed will blink and turn to normal characters to show  
programming did occur.

Bands F to E are always base transmit bands (beltpack receive  
bands). Bands 1-7 are always base receive bands (beltpack  
transmit bands). Thus an A2 base station would be comprised  
of an A band transmitter paired with a 2 band receiver.  
Band Pairing for Systems  
All band pairs cannot be made into a system (a single system  
is comprised of a base and beltpack). Table 1 show the avail-  
able band pairings.

Table 1  
Available Band Pairings  
In Table 1 it can been seen that a C base station transmit band  
can be paired with 4, 5, 6 or 7 receive bands. However, a C3  
unit cannot be made. This is because a certain amount of fre-  
quency separation between transmit and receive bands is re-  
quired for good transmit and receive operation. If they are too  
close the RF performance of the system is reduced.
