Introduction
Thank you for purchasing an Onset HOBO data node. With
proper care, it will give you years of accurate and reliable
measurements.
The ZW-008 HOBO data node is configured with 2 analog and
2 pulse channels.
The analog channels accept a wide range of Onset and third-
party sensors/transducers with a 0-2.5 VDC output, including
external temperature and AC current sensors. Specifications
for Onset sensors can be found at www.onsetcomp.com or by
contacting your Onset Authorized Dealer. For 0-5 VDC, 0-10
VDC, or 4-20 mA output, use optional Onset part no. CABLE-
ADAP5, CABLE-ADAP10, or CABLE-4-20mA respectively.
Onset part no. CABLE-2.5-STEREO is required to connect to
the HOBO data node's pulse channels. (Connect the pulse
output device to the cable's black and white leads.)
Note: Refer to the Onset Wireless Data Node Setup Guide and HOBOware®Pro Software User Guide for information on
configuring and using the HOBO data node.

FCC Compliance
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC
Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This
equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the
instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not
occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be
determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one of the following
measures:
•Reorient or relocate the receiving antenna
•Increase the separation between the equipment and receiver
•Connect the equipment into an outlet on a circuit different from that to which the receiver is connected
•Consult the dealer or an experienced radio/TV technician for help
Changes or modifications not expressly approved by Onset Computer Corporation could void the user's authority to operate the
equipment.
To comply with FCC and Industry Canada RF radiation exposure limits for general population, the HOBO data nodes, receivers,
and routers must be installed to provide a separation distance of at least 20cm from all persons and must not be co-located or
operating in conjunction with any other antenna or transmitter.
Canada
This device has been designed to operate with the antenna listed below, and having a maximum gain of 1 dB. Antennas not
included in this list or having a gain greater than 1 dB are strictly prohibited for use with this device. The required antenna
impedance is 50 ohms.
To reduce potential radio interference to other users, the antenna type and its gain should be so chosen that the equivalent
isotropically radiated power (e.i.r.p.) is not more than that permitted for successful communication.
Approved antenna: Johanson Technologies P/N 2450AT45A100 1.0 dBi chip antenna
FCC Declaration of Conformity
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device may not
cause interference, and (2) this device must accept any interference received, including interference that may cause undesired
operation.
