When settings are finished and ready to transfer to the monitor unit, the configuration unit will re-
spond with “Send data to unit”�
Fig. 65. Send data to unit (both sensor and master/slave unit)
If, for some reason, the transmission fails, the configuration unit will respond with “Send failed Try
again”�
The user then has to find out what has caused the failed transmission before trying again� Please
check cable or battery in the configuration unit for possible problems�

Cabinet Wiring
The cabinet(s) for all the DIN rail mounted Parking Guidance System modules is(are) suggested to be
placed in the middle of the system in order to have a uniform load� This is also a cost benefit (only
few cabinets are used) and will reduce the length of cable to the sensors� This has already been dis-
cussed earlier in the section “Phase two” on page 6�
Reducing the length of cable to the sensors means that it is possible to mount more sensors on the
same L1 bus� This can reduce the number of CPM modules etc�
However, if requested, the cabinet(s) can be installed away from the system or just at the end of the
system� If the rules mentioned in “Phase two” are not obeyed, it is important to perform a load and
voltage drop calculation� See section “System Calculation” (page 55)�
