INTRODUCTION
External keyboard KB1 is used for controlling
of up to 240 devices in a range 1000 m. All
devices are connected with CAN bus (shield-
ed twisted pair cable). Keyboard KB1 can
control pan-tilt units, zoom lenses and multi-
plexers.
Keyboard sends commands with the con-
trolled device address (e.g. TC) that receives
the commands and executes it (e.g. switches
on rotator turning). There is no difference
between operating a multiplexer with the ex-
ternal keyboard and the multiplexer local
keyboard. External keyboard KB1 light indica-
tors show the state of the controlled device.
The sound signalling is also transferred to the
keyboard.

CAN BUS
All controlled devices (pan-tilt units, zoom
lens, multiplexers) are connected using the
CAN bus that consists of shielded twisted
pair cable. Maximum length of the bus is
1000m. Maximum length of one stub is 60m
and length of all stubs must not exceed
300m. The terminators 120 are required at
the both ends of the bus. CAN bus is con-
nected with the 4-pins MINI DIN connector
(see picture 3). Transfer speed is 50 kBd.

INSTALLATION
POWER SUPPLY CONNECTING
Put the connector of power adapter into the
socket no.1 of the KB1 keyboard that shortly
beeps.
CAN BUS CONNECTING
Connect the KB1 keyboard and CAN bus with
4-pin mini din male connector. Outlets
CAN_L and CAN_H connect with the Can
bus. CAN_GND connect to cable shield.
CAN_V+ is used only for possible charging of
converters. All devices must be connected to
CAN bus in this way. The terminators
120 are required at the both ends of the
bus.
KEYBOARD SETTING
Set the address of KB1 keyboard first. Every
device connected to the bus must have its
own unique address in a range 1-240. KB1
keyboard has pre-installed address 10.
Entering the device address is necessary for
its use. After switching on KB1 has set ad-
dress of the last used device.

MULTIPLEXERS NETWORK EXAMPLE
Picture 6: Multiplexer network diagram
In the picture 6 there is shown a diagram of
connecting three multiplexers using the CAN
bus. Multiplexers 1 and 2 have several cam-
eras connected. Some of the cameras are
equipped with pan-tilt unit and the zoom lens.
Using the remote controlled video switcher
(multiplexer 3) it’s possible to display the con-
trolled multiplexer output. Main outputs of
multiplexers 1 and 2 are connected to inputs
1 and 2 of the video switcher (multiplexer 3 -
see picture 6). The output of the auxiliary
video switcher (multiplexer 3) leads to the
monitor input.
The sequential switcher of the multiplexer 3
can be used instead of video switcher. The
rest of the multiplexer video input can be
used as needed, but at this case the sequen-
tial switcher of this multiplexer can not be
used in other way.
For simple use of this system set the key-
board:
1. Set the auxiliary video switcher (multi-
plexer) address. Store the multiplexer
1 address in the memory 1.
2. Store the multiplexer 2 address in the
memory 2.
Selecting the address of multiplexer no.1 or
no.2 (pressing KB1, 1 or KB1, 2 keys) is aux-
iliary video switcher automatically switched to
the input of corresponding memory number.
Deleting the video switcher address the key-
board stops transmitting of switching com-
mands to the switcher. The camera and its
pan-tilt unit (see picture 6) can be controlled
by selecting the multiplexer 1 address and
selecting the camera at this multiplexer. The
telemetry commands of this multiplexer are
leaded to the camera telemetry receiver. This
camera can be also controlled directly by
selecting the address of telemetry receiver.
Connecting the camera video output to auxil-
iary video switcher input is necessary for dis-
playing camera pictures on the monitor

KEYBOARD USING
The keyboard informs about the current state of the controlled device using sound signalling (see
tab 1). In case of being the controlled device on the keyboard shows also the state of the light in-
dicators. Pressing the key assigned to a controlled device currently used by some different user
would be ignored and the keyboard signal long beeps. Device can be controlled 5 sec. after the
end of using by another user.

KEYBOARD SETTINGS
You can enter the keyboard mode by press-
ing KBD key that is signalled with KBD light
indicator. The keyboard doesn’t transmit any
commands or show the state except for CAM
and MON keys (reserved for later use). All
keyboard settings are stored in EEPROM
memory and are not lost even the keyboard
is turned off.
DEVICE SELECTING
To control any device connected to the CAN
bus you have to enter its address. There are
two ways: direct entering and using the
memory.
DIRECT DEVICE SELECTING
Direct device selecting is made by following
keys pressing:
Pressing ADR the keyboard shows the ad-
dress of the currently selected device.
DEVICE SELECTING USING THE MEMORY
Following keys pressing makes device select-
ing using memory:
This selection is successful only if the ad-
dress of controlled device is stored. If the
entered memory is not pre-set, the keyboard
beeps and previous device stays active.
STORING THE ADDRESS INTO MEMORY
The keyboard allows selecting the device
addresses using the memory for more com-
fortable use. To be able to use the memory
the addresses of the controlled devices must
be store in it. The current address of con-
trolled device is stored.
Storing procedure: Select the address of the
device first and store it into the memory
pressing the following keys:
During the storing (after RECORD is
pressed) keyboard shows already used parts
of the memory.
KEYBOARD ADDRESS SETTING
Following keys pressing makes keyboard
address setting:
Pressing MENU keyboard shows current ad-
dress of the keyboard. The KB1 keyboard
has pre-installed address 10.

THE NUMERICAL ADDRESS SETTING
In the setting procedures the numerical ad-
dress setting is signed:
The numerical address is a succession of
digits. For example address 123 is set by
following 1,2,3 keys pressing.
The address in range 1-16 is set by pressing
key 1-16.
In case of the selecting address greater than
9 the 10 key has value 0. For example press-
ing 2 and 10 keys sets address 20.
VALUE DISPLAYING
KB1 keyboard shows current state of previ-
ous settings by the light indicators during
setting of several parameters. For example
during a direct address selection is displayed
the currently selected address. The address
is displayed as a digit sequence. The ad-
dress 123 is displayed by following 1,2,3
blinking. The address in a range 1-16 is dis-
played by the still lighting indicator 1-16. In
case of the selecting address greater than 9
the light indicator 10 displays 0.

YOUR TROUBLE
CAUSE AND ITS SOLUTION
After the power cord-
connecting Kb1 doesn’t
beep.
The power cord is not connected.
Check the power socket and its polarity.
Insufficient power adapter.
Check whether the voltage and the consumption of the used
adapter respond to demands of KB1 keyboard.

to KBD pressing.
There is no controlled device selected.
Select a device with its valid address.
KB1 doesn’t control re-
mote device
(doesn’t beep twice after
selection)
The keyboard or the controlled devices address is set wrong.
Check the address setting.
CAN bus is disconnected or not incorrectly connected.
Check the CAN bus connection, both at KB1 and at the controlled
device. Check the cable and the bus terminator.
Controlled device is off.
Check whether controlled device is on and connected correctly to
the CAN bus.
KB1 doesn’t control re-
mote device and beeps
long after key pressing.
Another user controls remote device.
It will be possible to control this device 5 seconds after the last use
by another user. Wait 5 seconds and try again.
During controlling several
keys doesn’t respond.
The key has no use for this device.
Check whether there is some use for the key to control this device.
(Keys with no importance for the controlled device are ignored).
