LONWORKS COMMUNICATIONS

General Information

The EAGLEHAWK can be connected to L
This requires the use of an IF-LON (see section "IF-LON"
below), which is then plugged into to the EAGLEHAWK's USB
2.0 Host Interface (see also section "USB 2.0 Host Interface"
on pg. 5).
This permits individual EAGLEHAWK controllers to be
connected / disconnected from the L
without disturbing the operation of other devices.
The L
W
network is insensitive to polarity, eliminating
ON
ORKS
the possibility of installation errors due to miswiring.
Different network configurations (daisy-chain, loop, and star
configurations, or any combination thereof) are possible (see
also Excel 50/500 L

IMPORTANT
Do not bundle wires carrying field device signals or

communications together with high-voltage

ORKS
power supply or relay cables. Specifically, maintain a
min. separation of 3 inches (76 mm) between such
cables. Local wiring codes may take precedence over
this recommendation.
IMPORTANT
Try to avoid installing in areas of high electromagnetic
noise (EMI).
Cable Types
The unit must be wired to the L
level IV 22 AWG (Belden part number 9D220150)
or
plenum-rated level IV 22 AWG (Belden part number
9H2201504) non-shielded, twisted-pair, solid-conductor
wire.
When possible, use Honeywell AK3781, AK3782, AK3791, or
AK3792 cable (US part numbers). See Excel 50/5000

IF-LON
The IF-LON is equipped with a free-topology transceiver
(FTT10A) for communication (at a data transmission rate of
78 Kbaud) on L

® networks (using the LonTalk

protocol).
The L

network is insensitive to polarity, eliminating

figurations, or any combination thereof) are possible. See
