The HiPR-900 wireless modem consists of a logic PCB (which includes modem circuitry) and a radio
module. Each logic PCB and radio module is constructed in the factory to optimize performance as a
wireless modem. The two boards are installed in a cast aluminum case.
The HiPR-900 wireless modem “hops” from channel to channel several times per second using a “hop”
pattern applied to the Master and Remotes in a network. A distinct hopping pattern is provided for each of
the available System IDs. This distinct pattern minimizes the chance of interference with other spread
spectrum networks. In the United States and Canada, no license is necessary to install and operate this
type of spread spectrum system.
The unit is not hermetically sealed and should be mounted in a suitable enclosure when dust and/or a cor-
rosive atmosphere are anticipated. Physically, there are no external switches or adjustments. All operating

2. Installation
2.1 Parallel Decode
Dataradio's proprietary patent-pending Parallel Decode(tm) technology combines Spatial Diversity and
Smart Combining to provide increased sensitivity plus immunity to multipath fading. Even in the ab-
sence of motion, the changing wavelengths inherent in frequency-hopping systems makes it possible for
stationary sites to experience frequency-selective interference. Parallel Decode technology receives and
continuously combines signals from two antennas a short distance apart, ensuring a more reliable link.
The dual antenna connections also permit the use of a higher-gain antenna for the receiver. Full 1W
transmit power can be used with up to 6 dBi antenna gain.
Dual antenna ports also permit listening to a far distant site with a high- gain antenna while using an omni
to serve local stations. The Parallel Decode receiver algorithm automatically and continually decodes sig-
nals from both antennas.
In special applications such as rotating machinery, dual antenna ports allow the use of cross-polarized
antennas, automatically selecting the best signal regardless of the orientation of the machine.
2.2 Antennae Installation
2.2.1 Professional Installation & RF Exposure Compliance Requirements
The HiPR-900 radiomodem is intended for use in the SCADA market. The HiPR-900 must be profession-
ally installed and must ensure a minimum separation distance of more than 9.06 in. (23 cm) between the
radiating structure and any person. An antenna mounted on a pole or tower is the typical installation and
in rare instances, a 1/2-wave whip antenna is used.
The HiPR-900 radiomodem uses low power radio frequency transmitter. The concentrated
energy from an antenna may pose a health hazard. People should not be in front of the an-
tenna when the transmitter is operating.
RF Exposure
The installer of this equipment must ensure the antenna is located or pointed such that it does not emit an
RF field in excess of Health Canada limits for the general population. Recommended safety guidelines for
the human exposure to radio frequency electromagnetic energy are contained in the Canadian Safety
Code 6 (available from Health Canada) and the Federal Communications Commission (FCC) Bulletin 65.
Proper installation of the transceiver antenna of HiPR-900 products, as summarized in section 2.2.2 be-
low, will result in user exposure substantially below the recommended limits for the general public.
The HiPR-900 complies with Part 15 of the FCC rules and must be professionally installed. Operation
must conform to the following two conditions:
• This device may not cause harmful interference.
• This device must accept any interference received including interference that may cause unde-
sired operation of the device.
Notes: Any changes or modifications not expressly approved by the party responsible for com-
pliance (in the country where used) could void the user's authority to operate the equip-
ment.

2.2.2 Antenna Connection
This equipment has been tested and approved with antennae having a maximum gain of 8.5 dB. Antenna
with a higher gain are strictly prohibited (regulations of Industry Canada). The required antenna imped-
ance is 50 ohms. To reduce potential radio interference, the antenna type and its gain should be chosen to
ensure the effective isotropic radiated power (EIRP) is not more than required for successful communica-
tion.
FCC/IC Rule: The output power is not to exceed 1.0 watt (30 dBm) and the EIRP not to exceed 6 dBi
gain (36dBm). A sample calculation is provided below.
Referring to Figure 2:
Sample Calculation: Yagi Antenna: 8.5 dBi, which exceeds 6 dBi gain by 2.5 dB
Cable Loss: 1.5 dB
HiPR-900 output initially set to 30 dBm (1 watt).
(Initial output level) dBm - (excess antenna gain) dB + (cable loss) dB = (new power setting) dBm
Therefore, the sample calculation becomes: 30dBm – 2.5 dB + 1.5dB = 29 dBm
The HiPR-900 output must be reduced by 1 dB to 29 dBm.
29 dBm
“T” = TX/RX
“R” = RX

2.2.3 Spacing and Constraints
Referring to Figure 3, HiPR-900 radiomodems commonly use two separate antennae:
• “T” - Main transceiver -
Constraints are the limit of 9.06 in/23 cm (see 2.2.1 above) and omni-directional factors
• “R” - Auxiliary receiver –
Constraints are the receiver spacing of at least 5/8 λ(wavelength) from transceiver antenna and omni-
directional requirements (8in. / 21cm)
For the optimum antenna spacing at the frequency you are using, consult Dataradio System Engineering.

For installation of ground-plane dependent antennas, the center of the surface used for mounting is pref-
erable for best omni-directional pattern. For ground-plane independent antennas, installation may be close
to the edges of the mounting surface.

2.3 Network application
HiPR-900 is suited to a variety of network applications. Its primary design goal was to satisfy the needs
of SCADA systems using RTUs or PLCs in either point-to-point or point-to-multipoint service. This sec-
tion gives an overview of some common configurations.
2.3.1 Modes
2.3.1.1 Bridge mode
Bridge mode provides for fast set-up. IP bridging for quick deployment of basic point-to-point and point-
multipoint networks with minimal configuration. Bridge mode carries ARP and is transparent to any IP-
based or IP-encapsulated protocols.
2.3.1.2 Router mode
Used in advanced networks, router mode enables OIP optimization for reduced overhead and improved
throughput, and supports more complex network topologies such as store-and- forward and multihop
links. There is only one model to buy or stock because any HiPR900 unit can be configured for bridge or
router mode, router gateway (access point), remote station, or even as a combined store-and-forward re-
mote with a local drop.

Selection of “master” or “remote” as well as data delivery conditions is done using the web browser.
2.3.2 RF Path and communications range
The reliable communication range of the HiPR-900 is dependent on terrain, RF (radio frequency) path
obstacles, and antenna system. To assure reliable communications, a competent professional who can de-
termine what antennae are required and whether or not a repeater is needed should study the RF path be-
tween stations.
2.3.3 COMMON CHARACTERISTICS
The networks described in this section share common characteristics:
1. The network speed (256 and 512 Kbps) varies in a network as the Master announces the speed to
use to the remote stations.
2. Transmission of online diagnostics may be enabled or disabled at any station or stations without af-
fecting their ability to communicate with other stations.
2.3.4 Basic connections
The connections required are shown in Figure 4.
While an RTU or PLC is shown in the diagram, master stations often use a PC running an application de-
signed to communicate with remote RTUs or PLCs. The Setup PC is used for both configuration and local
and remote diagnostics. It may be left connected at all times but is not required for normal operation once
the unit has been configured.

A basic Point-Multipoint system for polling application is shown above. Using a web browser, one HiPR-
900 unit must be set to “Master”. The remaining units in the network must be set to “Remote”. All units
are set to “selective” data delivery to prevent remote stations from hearing each other's responses.
Ethernet network connection is also possible using bridge mode.

2.4 Selectable Data Rates
Switchable data rates of 256 and 512 Kbps allow optimizing installations for highest throughput or
maximum range. The sophisticated DSP modem gives optimal performance in either mode, whether a
short-range LAN extension or long-range point-to-point link.
2.5 Combined Access Point and Remote
Any unit can be configured as a Master station, and as an Access Point or Remote. This flexibility allows
the backbone network to be connected wherever it is most convenient, and completely independently of
where the Master station is located. Deployment and keeping spares is simplified with only a single
model required.
2.6 Online & Offline Diagnostics
HiPR-900 units continually monitor and report on their environmental and operating conditions. Each
transmission carries online diagnostic information that can be monitored remotely or even sent to a desig-
nated host for logging and later analysis.
Additional information, statistics, and offline test facilities are available via the browser. RF paths can be
monitored and checked from either end of a link, without travelling to the other station.
2.7 Built-in Spectrum Analyzer
Dataradio's innovative built-in Spectrum Analyzer continually monitors signal strength at each unit dur-
ing normal operation. The spectrum analyzer can also scan the band on command to establish the noise
floor and check for foreign signals or other sources of interference. Noisy or occupied sub-bands can be
locked-out.

The front panel includes:
• One standard RJ-45 autosensing 10/100 UTP Ethernet connection with Auto-MDIX. Supports di-
rect connection to both Terminal Devices and Ethernet hubs or switches without resorting to
crossover cables. LED indicators make it simple to verify that Ethernet cables and connections
are good.
• Two DE-9F RS232 ports. Serial baud rates from 1200 to 115,200 are supported. The HiPR-900
radiomodem is factory set (default) for 19200 b/s, 8 bits, no parity, and 1 stop bit.
• The antenna connector for the transceiver is a female 50-ohm TNC type. The HiPR-900 is de-
signed to operate with an antenna having a maximum gain of 10 dBi. Antennae with higher gain
are strictly prohibited (FCC and Industry Canada). Required antenna impedance is 50 ohms.
• One TNC-type female antenna connector for the auxiliary receiver
• One right-angle power connector. The 10 to 30 VDC wide-range switching power supply permits
powering from 12 volt as well as 24 volt systems, and the high-efficiency switching design runs
cooler with less loss. The HiPR-900 automatically senses and switches between its DC input and
PoE, using the DC input if both are present. This minimizes the load on PoE Ethernet switches
while allowing them to act as a backup to the local power supply.
• HiPR-900 has five dual-color LED indicators. Their functions are shown in Table 3.
