The STULZ bus is a RS485 bus where up to 32 STULZ controllers can be connected with a WIB. The Stulz
bus is an RS485 bus with fixed transmission parameters such as baud rate 9600 Baud, 8 data bits etc.
Following values are valid for the RS485 bus:
Differential signal is transmitted via HIGH/LOW connection
Maximum length: ca. 1000m (3300 feet)
Maximal bus participant distance: ca. 35m (114 feet)
Maximal bus participant number: 32
Connection: 2 pole shielded data line, twisted in pairs with an impedance of 120 Ω
Controllers wired in series, not in star
Data bus termination resistor (R: 120 Ω) at the beginning and end of bus
The WIB has its own integrated termination resistor (R). This resistor must be activated by setting the switches
S1 - S4, when the WIB is at the beginning or end of the Stulz bus.
The Stulz bus is a two wire connection with a screen which must be twisted in pairs. The screen must only be
