Multidrop communication
Several DCU 305 R3 units may be connected together in what is known
as a multidrop network.
For this to work correctly, each of the connected units must have its
unique ID-number in the range 1-239. This is done using the parameter
program Rudolf.
Further, the multidrop net must be an RS-485 net. This means that RS-
232/RS-485 converter units, for instance the ICPCON RS232/RS485
unit, must be connected close to the communication port P3 of each DCU
305 R3 unit.
We recommend using a twisted pair cable with two pairs of at least 0.22
mm
2
, and capacity lower than 60pF/m.
Please contact your dealer or Auto-Maskin for correct dip setting and
cabling of these units in a network.
