EAGLEHAWK NX CONTROLLER – INSTALLATION & COMMISSIONING INSTRUCTIONS

PANEL BUS CONNECTION

The EAGLEHAWK NX controller features two RS485 interfaces to which Panel Bus modules can be connected: RS485-1
(consisting of push-in terminals 24 [GND-1], 25, and 26) and/or RS485-2 (consisting of push-in terminals 29, 30, and 31 [GND-
2]).
NOTE: GND-2 is internally connected with 24V-0 (terminal 1)

Panel Bus Considerations


RS485-1 (isolated)
Max. Panel Bus length:
-
o 40 meters. Any type of cabling and topology (including star and loop topology) possible. No additional end
termination permitted.
o 1200 meters (9.6 – 78.8 kbps) or 800 meters (115.2 kbps) (see also section "RS485 Standard" on pg. 10).
Mandatory twisted-pair or telephone cable and daisy chain topology. The EAGLEHAWK NX must be positioned at
one end of the Panel Bus, and an end termination (120 Ω) at the other end. Further, the three-position slide switch
(see Fig. 13 on pg. 9) must be set to "END."

RS485-2 (non-isolated)
Max. Panel Bus length:
-
o 40 meters. Any type of cabling and topology (including star and loop topology) possible. No additional end
termination permitted.
o 1200 meters (9.6 – 78.8 kbps) or 800 meters (115.2 kbps) (see also section "RS485 Standard" on pg. 10).
Mandatory twisted-pair or telephone cable and daisy chain topology. The EAGLEHAWK NX controller must be
positioned at one end of the Panel Bus, and an end termination (120 Ω) at the other end.
Must not extend beyond a single building or building floor
