IML communicator
A unique, state of the art handheld radio device, fusing advanced
audience interaction features with a voice communication system for
meetings of all kinds and in all situations.
Base
station
RS232
Cable
Computer
IML communicators enable an audience to view information on the handset
screen, respond with data by using the keypad, and to listen to audio, and to
transmit audio. The handsets use radio communication to transmit/receive data
and audio between a base station and the audience handsets. The base station is
a normal handset that is configured by the application or the operator to work as
a base station. The handsets are typically used with a PC application such as
IMLPort and IML Question Wizard. The PC is connected to the base station via
data (RS232) cable. The presenter runs the application and can then initiate
votes where the audience can then vote on their handsets, with the information
being transmitted back to the application via the base station. Applications such
as Question Wizard will display the vote results.
IML System Hardware
Base Station:
The base station comprises the radio module that transmits and receives
information to and from the keypads. The unit is connected to an available serial
port on the PC by means of a data cable and is monitored and controlled by the
application software.

power supply.
Each power supply can charge up to 50
keypads.
International Voltage Input: 100–240
Volts
Charging the Communicator Keypads
For power, a Communicator keypad requires 4 x NiMH (Environmentally friendly)
AAA rechargeable batteries. The keypads are charged in modular racks that are
also used to store them when they are not in use.
Each charging module contains up to 5 keypads and up
to 5 of these modules can be locked together to form a
25 keypad rack.
The charging racks may be wall mounted or supplied
with either a soft carrying case or a hard shelled flight
case which includes an integral cooling fan to keep the
keypad batteries cool during charging.

PC Application
Start up the PC and its applications (e.g. IMLPort) following the guide for the
application.
Initialising the Base Station:
•
Select a fully charged Communicator keypad from the charging rack.
•
Identify the base station cable and connect the blue mini-jack, to the blue
I/O data socket at the base of the keypad.
•
The I/O port socket on the Communicator is located at the bottom right
hand side of the keypad, is coloured blue and labeled with an ‘opposing
arrows’ symbol inscribed on the underside of the case.
•
Connect the other end of the cable (9-pin female D-Type) to the correct
serial port on the PC (This is the serial port that was configured in the
application).
•
Power up the Communicator by pressing the red power button on the
keypad.
•
Some applications will automatically switch the handset into base station
mode, others require the use of a base station smart card.
•
Confirm that a beep is heard and that the keypad has been initialized as a
‘BASE STATION’. The LCD will be displaying the words ‘BASE STATION’.
10
Connecting the Communicator keypads to the system:
There are two methods of connecting the Communicator keypads to the system:
(1) Individually from power down
If the Communicator keypads are switched off (the display is blank), press
the round red power on button at top left side of the keyboard.
Allow up to 10 – 15 seconds for the keypad to connect to the base station.
• The flashing LED at the top edge of the Communicator and the
‘Signal Strength’ icon on the display will indicate the connection
status.
• Flashing green indicates a connection with a strong signal
• Flashing orange indicates an acceptable signal for data (i.e. voting)
but not for audio (i.e. microphone).
• Flashing red indicates that the keypad has not connected to the
base station.
(2) Globally from the charging rack
Ensure that the charging rack(s) are switched on and charging the
Communicator keypads.
To automatically connect the keypads to the base station, either remove
the keypads from the rack or switch off the power to the charging rack(s).
When Communicator keypads are in their charging racks with the charger
on they are automatically switched off and cannot communicate with any
Base station. As soon as the charging is stopped or the keypads are
removed from the charger the keypads switch on and snoop around for a
base station with the same base number as their own. If a Base station
signal is not detected after 15 seconds, the Communicator keypad will
power down.
Allow up to 10 –15 seconds for the keypad to connect to the base station.
• The flashing LED at the top edge of the Communicator and the
‘Signal Strength’ icon on the display will indicate the connection
status.
• Flashing green indicates a connection with a strong signal
• Flashing orange indicates an acceptable signal for data (i.e. voting)
but not for audio (i.e. microphone).
• Flashing red indicates that the keypad has not connected to the
base station.

Powering down the Communicator keypads
There are several methods of powering down the keypads. These methods
depend on whether the keypads have connected to a base station or not.
If the Keypads have not connected to a base station then there are two ways of
powering down the keypads:
1. Press the red Power On/Off button on the keypad
2. Place the keypads in the charge racks and switch on the power to the
racks.
If the keypads have connected to a base station the Power On/Off button on the
keypad may have been disabled by the application e.g. IML Question Wizard (this
is to stop the delegates from accidentally switching off the keypad during a
meeting).
1. Place the keypads in the charge racks and switch on the power to the
racks.
2. Press the power On/Off button if this has not been disabled by the
application
3. Use application specific commands or methods, refer to application
documentation for details.
12
Base Numbers, UIDs and Indexes
The IML Communicator System utilizes a license free radio band 2.45 GHz
employing spread spectrum frequency hopping protocols. Basically this means
that the system provides assurance that it will operate in high interference
situations and when other radio based system are being used e.g. wireless LAN,
Blue Tooth etc.
You may have noticed that when a Communicator keypad is
powered up and not connected to a base station, the LCD
display shows a Base Number and an Index Number.
What is a BASE number?
A Base number is similar to channels and can be set to any value from 0 to 99.
The base number must be set in each Communicator and it must be the same as
the base number set in the base station that you want it to connect to.
The advantage of being able to set different base numbers in a system is that it
allows different interactive presentations to be run in close proximity without
interference.
When a system leaves the factory, the default base number for the keypads is set
to Base 1.
How to change the Base Number
There are two methods of changing the base number on a keypad:
(1) Using a Base Number Smart Card (Currently not released)
(2) By placing the keypad into Base Number Setup Mode by entering a special
coded number.
Step 1 - Ensure that the base station and keypads are switched off
Step 2 - Switch on a keypad. The keypads LCD will display
COMMUNICATOR, the BASE number and the INDEX number.
Step 3 - Type in the word BASE on the keypad using the letters
printed on the buttons, i.e. 2273
Step 4 –
•
Enter the new Base Number.
clear your input if necessary.
•
Press the Blue Soft Key to set the new Base Number
•
Power down the keypad
Use the ‘C’ button to
Ensure that all the keypads have the same base number – including the base
stations.
13
What is a Unique ID (UID)?
A Unique ID (UID) is the number printed on the Communicator label. It is set
inside the Communicator during manufacture and will never be changed. It
ensures that all Communicators can work together on the same base station
without clashing.

to the user:
• Base Station:
This indicator flashes green to show that the
Communicator keypad is connected to the base station,
flashes orange to show that the signal level is low and
flashes red to show that it is attempting to connect to the
base station.
• Charging:
When the Communicator is in the battery charging rack,
the indicator shows the keypads recharging progress
within the charging cycle. Red for low, orange from low to
nearly complete and green for complete. The LED blinks
to show it is being charged and is viewable from outside
the charging rack.
• Blue on green dot matrix LCD

for approx. 10 seconds whenever a key is pressed.
• 97 x 32 pixels display
• The display includes 5 icons to display battery power,
signal strength, current time, message pending and alarm
bell.
(4) Power On / Off
(5) Cancel Key
The battery power icon has three segments to
indicate the amount of battery remaining.
- The signal strength (aerial) icon has five bars
indicating the signal strength.
- The clock icon displays the system time in HH:MM
which follows the PC clock.
- The envelope icon is currently not implemented.
- The alarm icon is displayed if the keypad anti-theft
alarm has been enabled.
• Customizable fonts and icons may be configured for the
display (i.e. company logo).
Power button for switching the Communicator on or off.
• During normal operation (e.g. when used with IML
Question Wizard), the keypad cannot be manually powered
off once it has connected to the base station; this prevents
the user accidentally switching off the device during a
meeting. A password can be entered onto the keypad to
re-enable the power off mode.
• A global power down command from the IML Question
Wizard can be sent to power down all connected keypads.
• In number entry fields the cancel key clears the display &

The internal sounder is used ….
o to generate an audible sounds when keys are pressed
on the keypad
o to trigger an alarm sound when a keypad is out of
range of the base station. i.e. If the Communicator is
taken out of the meeting room and loses the base
station signal, the sounder will automatically trigger
and a message to return the keypad back to the
administrator will be displayed on the LCD display. The
sounder will stop and the message will clear from the
LCD display when the Communicator reconnects back
to the base station. The trigger signal strength can be
adjusted to suit the room.

The Communicator Keypad FAQ
Base station
Q: Can any Communicator be used as a base station?
A: Yes, any Communicator goes into base station mode when connected to a PC
that is running the appropriate IML software, or if manually changed into base
station mode.
Q: Will the Communicators stay connected if I disconnect the Base
Station data lead?
A: Yes.
Q: Why doesn’t the LED flash normally on the base station?
A: The base station LED cannot indicate the signal strength of every
Communicator that is connected to it so it is not used in this way – see next Q.
Q: What do the occasional red, orange and green LED flashes indicate on
the base station?
A: The Communicator LED behaves differently in base station mode. It does not
indicate signal strength as it does in normal mode. A red flash indicates a
message has been received by the base station from one or more
Communicators. A green flash indicates that a command has been transmitted
from the base station to one or more of the connected Communicators. An orange
flash indicates that commands and messages are passing between the base
station and Communicators.
Base number
Q: What is the Base number?
A: The base number can be any value from 0 to 99. Using different base
numbers allows different interactive presentations to be run in close proximity
without interference.
The base number must be set in each Communicator and it must be the same as
the base number set in the base station that you want it to connect to.
Q: When would I need to change to a different base number?
A: If you discovered that you were using the same base number as another user
close to you - either you or the other user would need to change to another base
number.
Q: How do I tell what the current base number is?
A: Look at the displays on the base station or Communicators.
Q: What happens to a Communicator with the wrong base number.
A: Communicators with a different base number to the base station will not
connect. They will not interfere with the system. Check the base number
displayed on the base station and use the base numbering smart card as above to
set the Communicator to the right number.
Q: What happens if I connect up more than one base station with the
same base number?
A: This is not recommended and the system may be unreliable. Communicators
do not necessarily connect to the strongest signal.

Handset
Q: What is the unique ID (UID)?
A: It is the number printed on the Communicator label. It is set during
manufacture and will never be changed. It ensures that all Communicators can
work together on the same base station without clashing.

Communicator Charging FAQ
Q: When Communicators are in the charger and you switch off the power
supply, why do they sometimes stay on and at other times switch off?
A: You will notice that if the base station is on they will connect and stay on but if
the base station is off they will also switch off. The rule is - if they have
connected at any time they stay on but if they cannot connect at all they switch
off.
Q: If I pull out a Communicator when it is on charge does it follow the
same rule as above.
A: Yes. Pulling out a Communicator when it is on charge is the same as switching
off the charger.
Q: Can the Communicators connect to the base station when they on
charge?
A: No. The Communicators are disconnected from the base station when they go
on charge.
Q: Does it matter in which order
Communicators are put into the rack?
and
which
way
round
the
A: No. As long as the Communicator is slid into the rack contacts first. The
Communicator’s keyboard can face up or down. The rack itself can also be used
either way up.
Q: Do I need to fill all the rack positions when charging?
A: No. If you distribute the Communicators across the rack modules they will
take less time to charge as the charger skips empty positions.
Q: Do fully charged or vacant rack positions get skipped?
A: Yes, they do not receive the 60 second charge cycle.
Q: Will Communicators charge faster when they are on their own?
A: A single Communicator in the rack will be fast charged one minute on and one
minute off etc so it will take 2/5th of the time it would normally take in a rack of
five i.e. roughly 2 hours for a full charge. A full charge for two Communicators is
also 2/5th.
Q: Sometime the charging cycle goes from top to bottom other times
from bottom to top, why is this?
A: The cycle order, either top to bottom or visa versa, will depend on which way
round you have positioned the rack.
Q. How do I know if the charging rack is powered on?
A. Either insert a Communicator keypad into the rack and check that the LED
turns Red or remove the keypad that is in the middle rack position (third down)
and note the green LED inside the back of the rack.
Q: Can the rack be stood on its backside?
A: Yes, as long as air can circulate into the racks from underneath.
Q: Can the charging rack be stood on it side?
A: This is not recommended, as the airflow is restricted.
26
Q: Can I charge more than 25 Communicators by linking up blocks of 25?
A: 2.5A power supply can charge up to 50 Communicators at a time, so you may
link two blocks of 25 Communicators together using the interconnecting DC-DC
cable between two outside charge rack sockets.
Q: How many racks can a power supply serve?
A: A 10V DC 5.5A power supply can power up to 50 Communicators in 10 racks.
Do not try to power more than 50 Communicators from a single power supply.
Q: Is it best to top up the Communicators after use or to use them until
flat before charging?
A: The NiMH batteries do not suffer the so-called memory effect experienced with
NiCad batteries so the Communicators may be topped up as a routine.
Q: Can I stop the charging half way through, use the keypads and then
put them on charge again?
A: Yes. They will start red but soon go to orange and then eventually to green.
Q: How do I extend the batteries serviceable life?
A: Store and charge in cool surroundings. Always allow air to circulate into
charger during charging.
Q: Do I ever need to replace the batteries?
A: All rechargeable batteries lose their capacity over time. As this time depends
on usage and operating environment it is not possible to be precise about this.
However they should expect them to retain enough capacity for 3-5 years.
Q: How long do the Communicators keep their charge?
A: After a month the Communicators may lose 10% of their capacity.
Q: How long can a fully charged Communicator run for?
A: In base station mode it will last 6 hours.
In standby or response mode a Communicator will last 36 hours.
In talk mode it will last 20 hours.
Q: Can the power supply be used abroad?
A: Yes, the power supply is 110-240V AC 50-60Hz. You will however require the
correct mains plug for the country you are working in.
Q: Can the racks be used individually?
A: Yes. Two metal ties hold the racks together. These may be unscrewed to
release the individual racks. There are two inter-connecting pin sets between
each pair of racks that must be kept for when the racks are re assembles into a
block.
Q: Can different numbers of racks be fitted together?
A: Yes. Phone the IML Sales department for availability of different tie bar
lengths.
Q: Can the contacts on the Communicator erase floppy disks?
A: No. The magnets are inside the charging case and the Communicator contacts
never get magnetized.
Q: Can I get a shock from the Communicator contacts?
A: No. Power is not available from these.
