This section describes how to make a quick installation following the step by step
instructions below. See to that the control software files delivered on the CD-
ROM are loaded into the PALM. For more information on how this is done,
please consult your PALM user manual.
1. Connect the EFM-100 to a DC power supply (the ESP-100 or EPP-100). Then
connect your PALM PDA to the EFM-100 with a PALM Hotsync cable to the
RS-232 serial port on the front of EFM-100.
2. Tap the EFM icon in the A2B Control menu of the PALM.
3. A Welcome menu should appear if your PALM is in contact with the EFM-
100. Click [Next].

4. The settings window allows you to enable and adjust the various functions of
EFM-100. The Amplifier, the RF output attenuation and the OSD video settings
are all handled via drop down lists, while pop-up windows are shown when
selecting the Tuner or the Modulator.
With the Amplifier enabled you can attenuate the RF out signal (Level) between
0 to -31dB in 1dB steps. NOTE! The RF attenuator is always enabled.
. The Tuner can be enabled or disabled. When enabled, the audio connectors act
as outputs. The frequency of the Tuner can be adjusted between 76 and 108 MHz
in 0 kHz steps. If needed the Tuner can be set to Mono mode. Make your
choice and click [ OK ].
6. The Modulator can be enabled or disabled and if enabled the output frequency
can be adjusted between 76 and 108 MHz in 0 kHz steps. The output level can
be adjusted from 0dB to -6dB in four steps. NOTE! As shown in the Block
schematic (see page 11) the Modulator output level is also affected by the RF
output attenuator.

7. The video OSD output (On Screen Display) can be set to indicate “P1” to
“P7” in the upper right corner on TV sets connected via an RF modulator (as
the EVA-200 or EVA-210). If you select “Black” the screen will be blank. This
function can be used when the EFM-100 is installed in a hotel system. The
OSD output can also be disabled. Do the settings you want and click [ Next ].
8. The settings will be stored automatically when entered, and you should now
have the signal(s) out from the EFM-100 according to the settings you have
made. Click [ Next ] and your setup is completed. Click [ Again ] if you want
to change some settings. If you want to connect your Palm to another E-series
module you first click [ Again ] and then you click [ Exit ].
Disconnect the PALM
from the EFM-100
and the installation is ready.
It is possible to change from Stereo to Mono Mode if wanted. You can also
attenuate the incoming LF signal (from phono left and right) by 9dB if
necessary. The RDS Name box allows you to send your own RDS info with up
to 8 letters. Leaving the RDS Name field blank disable the RDS transmission.
The preemphasis is setted to 7 µsec as default but can be changed to 0 µsec
or can be set to Disabled. NOTE! 7 µsec shall be used for all normal purposes.
Perform desired settings and click [ OK ]

This section describes how to make a first time installation for PC following the
step by step instructions below. See to that the control software files delivered on
the CD-ROM are installed on your PC. You can also download Control software at
www.a2b.se/support .
Connect the EFM-100 to a DC power supply (the ESP-100 or EPP-100).
Then connect your PC to the EFM-100 with a null modem cable from a serial port
on the PC to the RS-232 port on the EFM-100.
Select the correct COM port and press [OK] and following menu should appear.

Below you find description of the different settings in the main menu. See Block Schematic in next page
1. VIDEO OSD ( TV OSD )
If you connect the Video connector of the EFM-100 to an RF modulator or direct to a
TV set, you can here choose if you want to put a text (P1 to P7) in the signal that will
appear on connected TV sets in the right upper corner of the TV picture or select
“Black” for a blank screen. (For instance when EFM-100 is installed in a hotel system).
2. FM TUNE
Set this to ON (click in the box) to activate the FM tuner. This give you the opportunity
to remodulate the received signal to a different output frequency using the FM
Modulator. You can also use the demodulated LF on the R and L audio connectors for
connection to a RF modulator ( for example EVA-200 or EVA-210). Click in the
frequency box and enter a frequency between 76 and 108 MHz (can be selected in 0 kHz
steps). Click on [ Program Frequency] to make the settings to take effect. You can also
select Mono mode instead of Stereo mode if wanted.
3. FM AMPLIFIE
If you set this to ON (click in the box) the EFM-100 will amplify all signals between
76 and 108 MHz that is received from the FM antenna input.
4. FM MODULATO
With this function set to ON you can choose output frequency either from a signal
source connected to the R and L audio connectors or choose a different frequency for a
FM signal from the FM Tuner. Click in the frequency box and enter a frequency between
76 and 108 MHz (can be selected in 0 kHz steps). If you connect an external audio
source you can attenuate the incoming signal by 9 dB (Audio Sensitivity).
Preemphasis is possible to change from 7 µsec to 0 µsec or Disable. NOTE! 7 µsec
shall be used for all normal purposes. If needed you can also choose Mono Mode. In the
box for RDS Programme service you can enter up to 8 letters. If you do that you have to
click on [ Program DS ] to enable the settings. Always press [Program Frequency] to
make the settings to take effect
5. F OUTPUT LEVEL
This gives you the possibility to attenuate output signal from FM Modulator ( 0 to -6dB ).
6. F OUTPUT ATTENUATO
Click on this drop list and you can attenuate the output level from EFM-100 between 0
and -31dB in 1dB steps. This function is always enabled.

The EFM-100 can be installed either stand alone or it can be installed in a base unit
(EBU-100) together with any of our high quality E-series products.
Before connecting power to EFM-100 make sure that all other connections are made.
If a stereo RF-modulator such as the EVA-210 is in use, connect Right and Left audio
outputs to the corresponding inputs on the EVA-210.
Also connect the video source (CVBS) to the video input of the RF-modulator
(EVA-200/210) if Video OSD is used.
Connect power supply and make all necessary settings as described in section 4 and .
