Appendix: The First Commissioning of AS-i

In this chapter an example is given of how to put an AS-i network into
operation quickly and easily and without the need for external devices.
The addressing of the components connected to the AS i network can
be performed directly on the AS i master. It is of course more comfort-
able to do the addressing with a hand-held programming device or a
PC. However, it is possible to configure even complex networks using
only the AS i master.
What to do ?
See to it that the AS-i master is properly
supplied with power.
After the self-test: the LEDs "power", "config err", "U ASI" and "prj mode" are on.
The LCD shows "40": the AS-i master is in the off-line phase. Shortly after that a
"41" will be displayed: the AS-i master stays in the detection phase.
Switch the device to the projecting
mode, if the yellow LED does not light
up.
The yellow LED "prj mode" lights up. The device is now in projecting mode.
Add a slave with the address 0 to the
AS-i line.
The green LED "ASI active" lights up. The LCD shows "0". This means the AS-i
master has detected the slave.
Change the slave address to address 1. Select address 1 by pressing the "set"
The AS-i master detects the slave with address 1 and displays "1".
Connect another slave with address 0 to
the AS-i line and allocate the address 2
to it.
The addresses of all slaves detected are now displayed sequentially.
Subject to reasonable modifications due to technical advances.

How to go about it?
Using AS-i master with power supply
"A": connect the AS-i power supply unit
to the terminals AS-i + and AS-i - of the
master, connect the ground terminal.
Using AS-i master with power supply
"N": connect the 24 V DC standard
power supply with the terminals 24V and
0V of the master, connect the ground
terminal.
Turn on the power supply.
Press the "mode"-button for approx. five
seconds.
Connect the slave's terminals with the
terminals AS-i + / - of the master.
button shortly, if necessary repeatedly.
When a "1" appears on the display press
the "set" button for approx. five seconds
until the display blinks. Press again
shortly the "set" button to assign the new
address to the slave.
Connect the slave to the AS-i line. The
addressing is the same as for the previ-
ous slave.
