The maximum configuration consists of 16 cooling units with an I/O controller and an
InRoom Controller. One of the features of the controller is its facility for bus operation.
All that is needed is a shielded cable with two lines twisted in pairs, which are connec-
ted from unit to unit at the terminals 56-59 of each I/O controller (IOC). In the example
below the bus termination of the two units that form the end of the bus (IOC 01 and
IOC 17) must be enabled.
The example of a RS485 bus shows a typical application with 7 IOCs and 1
InRoom
Controller
.
The bus address or bus ID is adjusted with the dip-switches on the IOC. The table at the
right shows the corresponding adjustment for all possible bus IDs. The counting begins
with 0 and ends with 31. A "1" means a dip-switch is in the ON position.
On an InRoom Controller the bus-ID is adjusted in the global status line (See chapter
5. Controller Start).
An IOC is delivered with the ID 01 as standard, an InRoom Controller has the ID 31 as
standard. After having provided all units (IOCs) with a different bus-ID, the units must
be declared as participants of the bus, for the bus exists up to now only physically. (See
next page).
To control the presence of each bus member, type
iobus and you will see a list as
follows:
ID type status availability
00 unknown passive 000
01 IO-controller active 255
02 unknown passive 000
03 IO-controller active me

In short:
1. Connect units by bus lines
2. Set bus terminations (beginning/end)
3. Adjust bus-IDs
4. Generate bus configuration (declare participants)
