AK-PI
300
• The installation of the data communication must be carried out
as specified in the guide to the RC8AC.
• The terminations must be in order.
• Up to 1 Comm. box + 3 RTD-network units can be connected to
a single AK-PI 300 unit.
• Up to two AK-PI 300 units can be connected to a single
system manager.
• Only addresses on the Comm. box can be offset.
• Furthermore, address numbers on an RTD-network must not also
be address numbers on an AK-SM 720 unit.
• A Comm. box registers 3 addresses on the Daikin Modbus net-
work: the one it is set with + the 2 subsequent ones. The units
on an RTD-network must not have an address that coincides
with these 3 addresses.
Requirements and terms
Principle
• Network addresses
Here is a small summary of the networks and addresses that can
occur:
11:001 is the master system manager
11:002 to 11:010 are slave networks controlled by 11:001
(the figure “11” keeps track of the networks and cannot be
changed).
11:012 to 11:999 are addresses for units on the network. The
units can be AK-PI 300 units or wireless units, or they can be
controllers in which the data communication takes place via
TCP/IP.
1: xxx will be controllers that are registered under the master
system manager.
2: xxx will be controllers that are registered under slave network
number 2.
