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 COACH NX engineering tool.

(EXAMPLE)
Fig. 38. Location of HEX switch on Panel Bus I/O Module
NOTE:
A HEX switch setting of "0" corresponds to an
address in COACH NX of "1," a setting of "1" cor-
responds to an address of "2," and so on.
During commissioning, a max. of 16 Panel Bus I/O Modules
of each type (AI, DO, etc.) 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.)
may be assigned the same address. See also Fig. 39.

Failing to observe this requirement will cause a "Fail [date]
timeout" error message to appear in the "Health" column, and
the device status "down" to appear in the "Status" column.
This same error message will likewise appear if an address is
assigned to a module with which the controller cannot, for any
reason (e.g., due to defective wiring, or because the module
has not been physically installed, etc.), communicate.
Automatic Updating of Panel Bus I/O Module
Firmware
The firmware of the Panel Bus I/O modules is part of the
EAGLEHAWK NX firmware. The EAGLEHAWK NX controller
will thus automatically update the firmware of the Panel Bus
I/O modules as soon as it detects an older version in them.
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.
Table 20. Power supply cable specifications
max. length
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, Modbus, and BACnet MS/TP).
Table 21. EIA 485 cable specifications
max. length
1200 meters (9.6 – 78.8 kbps)
or 800 meters (115.2 kbps).

twisted pair, shielded (foil or
braided shields are acceptable)

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.
