ADDRESS
Every produced unit of Central reading system CRS 40 is equipped with unique identification number of radio
module RFCC1101, so called RF MAC address. You can find this number on unit identification label. First
two groups of digits are unique for particular customer, next two identify particular unit.
There can be situations, when more billing companies provide their services in one housing estate (or even
in one large building). To avoid situations like that e.g. unit A of one billing company would connect to reading
network of another one, sameness of first two groups of digits is checked during connection establishment.
Warning
Only units with the same first four digits from RF MAC address (see Illustration 6: I Identification
label of the unit B, Illustration 5: Identification label of the unit A) can be used in one reading
network.
Units with different initial four digits of RF MAC address are not establish connection even when the setting
of DIP switch is the same. For more information, see chapter Configuration of multiple overlapping network.

OVERLAPPING
NETWORK
Mainly in the housing estate, it can happen that installation of more
reading networks in close buildings (or even in one building) is
necessary. Only installation of multiple reading networks of one
billing company with the same first four digits of RF MAC address
(see chapter 6.1. RF MAC Reading network address ) is described
in this chapter. Installation of more reading networks of more billing
companies does not require any further setting (see Illustration 8:
Overlapping networks of two billing companies).
To avoid connection of unit A to another reading network (i.e. to
another unit B), it is necessary to distinguish between such
networks.
Distinguishing between reading networks is done by DIP switch on
radio module RFCC1101 (see Picture 4: Schematics of the radio
module RFCC1101 and Illustration 7: Detail of the DIP switch). DIP
switches are set to position OFF-OFF-OFF-OFF (0-0-0-0) by
default.
It is possible to use default configuration of DIP switch when installing the first reading network. When
installing next reading network, it is necessary to change DIP switch to another configuration on both control
unit B and all collecting units A. 15 combinations can be used, configuration ON-ON-ON-ON (1-1-1-1) is
reserved by the manufacturer.
