During update of controller firmware by means of Roger ISP software (so called Fixed ID)
Manually during Memory Reset procedure
By means of PR Master software
The first two methods enable configuration of hardware addresses while the remaining two enable
configuration of software addresses. The main difference between these two addressing methods is
such that software address contrary to hardware address can be modified using any of mentioned
methods. Jumper address has the highest priority, Fixed ID has lower priority and software
addresses have the lowest priority.
Note: A new controller can be connected to the existing system without the necessity to change its
address but only if no other controller operates with default address ID=00. Once the controller is
connected to the RS485 communication bus, it should be detected by means of PR Master software
and new address should be configured.
4.1.1 Setting the address by means of jumpers
The address of controller can be set by means of jumpers – see fig. 12. Each time the new address
is configured, controller must be restarted (via RESET button or powering device off and on) to
make new settings valid. The address range is 00..127 and if the address is in range 100..127 then
the controller ignores such setting and all other addressing methods can be used. If the address is
in range of 00..99 then it has the highest priority, FixedID is not effective, and the address cannot
be changed by PR Master software nor manually during Memory Reset procedure.

4.1.2 Addressing during firmware update (Fixed ID)
FixedID can be set during update of the controller firmware by means of RogerISP software. Prior
to firmware upload, RogerISP software offers the possibility to set Fixed ID address in range of
00..99 or disable it (FixedID=None). Once the FixedID is selected and uploaded to the controller
software addressing is ignored. In order to disable or modify FixedID it is necessary to start
firmware upload procedure or configure jumper address in range of 00..99.
Note: When FixedID is configured then controller address cannot be modified based on software
addressing method. FixedID address is maintained even in case of controller configuration error.
Therefore controller can be always detected on the communication bus with the same address by
means of PR Master software.
