Addressing Panel Bus I/O Modules
Each Panel Bus I/O Module must be addressed manually
using its HEX switch (S2). The HEX switch setting is defined
using the engineering tool.
PANEL BUS I/O MODULE
(EXAMPLE)
Fig. 39. Location of HEX switch on Panel Bus I/O Module
NOTE: A HEX switch setting of "0" corresponds to an
address in the engineering tool of "1," a setting of
"1" corresponds to an address of "2," and so on.
A max. of 16 Panel Bus I/O Modules of each type (AI, DO,
etc.) per RS485 interface (i.e., per Panel Bus) can be
assigned addresses. In doing so, no two modules of the same
type (e.g., no two Analog Input Modules, no two Digital Output
modules, etc.) per RS485 interface (i.e., per Panel Bus) may
be assigned the same address.
Cable Specifications
Panel Bus I/O Modules
When checking the length of the power supply cable, the
connection cables to all Panel Bus I/O Modules must be
taken into account.

3 m (from transformer to final module)

EIA 485 Cable Specifications
The following cable specification is valid for all EIA 485 buses
(e.g., Panel Bus and BACnet MS/TP).
Table 22. EIA 485 cable specifications
max. length
1200 meters (9.6 – 76.8 kbps) or
1000 meters (115.2 kbps).
cable type
twisted pair, shielded (foil or
braided shields are acceptable)
charac. impedance
100…130 Ω
distributed capa-
citance between
conductors
Less than 100 pF per meter (30
pF per foot)
distributed capa-
citance between
conductors and shield
Less than 200 pF per meter (60
pF per foot)
The following cables fulfill this requirement:
AWG 18;
shielded, twisted pair cable J-Y-(St)-Y 2 x 2 x 0,8;
CAT 5,6,7 cable (use only one single pair for one bus);
Belden 9842 or 9842NH.
Field Devices
Depending on the distance from the controller, field devices
can be supplied with power by the same transformer used for
the Panel Bus I/O Modules, or by a separate transformer,
using cables as specified in Table 23.

For wiring field devices, see section "Powering Panel Bus I/O
Modules and Field Devices" on page 16.
Routing Cables to Field Devices
Route low-voltage signal and output cables to field devices
separately from mains cables.
Table 24. Minimum distances to power mains cables
cable min. distance
shielded 10 mm (0.4 in.)
unshielded 100 mm (4 in.)
All low-voltage signal and output cables should be regarded
as communication circuits in accordance with VDE 0100 and
VDE 0800 (or NEC or other equivalent).
If the general guidelines for cable routing are observed, it
is not necessary to shield field device signal and power
supply cables.
If, for whatever reason, the routing guidelines cannot be
observed, the field device signal and power supply cables
must be shielded.
– Shielding of cables leading to field devices must be
grounded only at one end.
– Do not connect the shield to the EAGLE Controller.
