IMX-A832I
July 2001, subject to change5
e) Alarm output (ALARM)1
The alarm output has +24 V DC output voltage by
alarm. The maximum load
from the output is 100 mA.
Connect the evaluation unit
between positive (terminal
number 33) and neutral
(terminal number 34), see
picture 2.

f) Master OUT
To synchronize more than one 8-channel multiplexer,
the MASTER OUT output (connection terminal
number 35, see picture 1) gives a signal to the
following device.
Note:Do not connect the MASTER OUT terminal
with the MASTER OUT terminal of the next
device
g) Slave IN
To synchronize more than one 8-channel multiplexer,
the SLAVE IN input (connection terminal number 36,
see picture 1) receives the signal from the previous
device.
Note:The SLAVE IN terminal should be wired to a
MASTER OUT terminal.
4. Master-Slave operation
The master-slave operation allows synchronized
action of multiple 8 channel devices, including all
Pantron manual and automatic series. Therefore, the
same channel number is active on each device in
the chain at the certain time (see picture 4). With a
suitable arrangement of sensor pairs, the mutual
influence between the amplifiers can be prevented.

Note:Do not wire the MASTER OUT terminal from
the last device with the SLAVE IN terminal from
the first device.
5. Operation mode terminology
The device has 2 different operation modes:
a) Normal mode
This is the standard mode that is implemented after
switching the supply voltage on, as well as after the
RESET push-button has been pressed.
b) Test mode
This mode is used for the physical alignment of
the sensor heads and to test the set up and wiring.
The multiplexer displays the following information:
Signal strength
Sensor error
selected basic transmit level
The sensor heads are activated cycling one after the
other.The state of each channel will not be shown
and the outputsmaintain the state they are in.
6. Functions terminology
The functions of the amplifier can be switched to
different working conditions. The functions are
selectable by DIP-switches behind the front panel.
a) Switching mode1
The switching mode describes the output behavior
on interruption of the infrared beam. There are some
differences in the light circuit (light)1and the dark circuit (dark)1.
Light mode operation: The output switches to ground
(terminal number 34).
Dark mode operation: The output switches to the
+24 V DC.
b) Basic transmit level (transmit power)1
The basic transmit level is the minimum transmit
power level of an infrared transmitter.
Low 1: This is the standard operating mode of the
automatic level control (ALC). The trans-
mit power level is always set to the optimal
value for constant high switching sensitivity.
Low 2: The multiplexer works like the Low 1 basic
transmit level but the device is less sensi-
tive.
High 1: The transmit power level is always at least
50 % of the maximum power level.
High 2: The transmit power level is always at least
90 % of the maximum power level.
