Extended Wiring for Parking Guidance System Software Solution
Pairing the simple stand-alone Parking Guidance System with a software solution, just requires a
daisy chained RS485 connection between all Parking Guidance System DMM modules in the entire
system� On the front side of the GP34960005700 modules a DP9 connector can be found for this pur-
pose� The RS485 is a robust bus which can transmit reliable signals up to 1200 m without problems�
The RS485 signal is transmitted to a RS485 / ethernet converter (ETHCONV4) that must be located
less than 100 m away from the ethernet router or the server for Parking Guidance System software� If
this is not possible, an optical solution can be used�
