STATEMENT OF WARRANTY
This product, except as stated otherwise in an applicable price list, is warranted against defects in
workmanship and material for a period of three (3) years from date of delivery as evidenced by the
manufacturer’s packing slip or other transportation receipt.
The manufacturer’s sole responsibility under this warranty shall be to either repair or replace, at its
option, any component which fails during the applicable warranty period because of a defect in
workmanship and material, provided PURCHASER has promptly reported same to the manufacturer
in writing. All replaced Products or parts shall become property of the manufacturer.
P-Com shall honor the warranty at its repair facility in Campbell, California. It is PURCHASER’s
responsibility to return, at its expense, the allegedly defective Product to the manufacturer.
PURCHASER must obtain a Return Materials Authorization (RMA) number and shipping instructions
from the manufacturer prior to returning any Product under warranty. Transportation charges for the
return of the Product to PURCHASER shall be paid by the manufacturer within the United States. For
all other locations, the warranty excludes all costs of shipping, customs clearance and other related
charges. If the manufacturer determines that the Product is not defective within the terms of the
warranty, PURCHASER shall pay to the manufacturer all costs of handling, transportation and repairs
at the then prevailing repair rates.
All the above warranties are contingent upon proper use of the Product. These warranties will not
apply (i) if adjustment, repair or parts replacement is required because of accident, unusual physical,
electrical or electromagnetic stress, negligence of PURCHASER, misuse, failure of electric power,
environmental controls, transportation, not maintained in accordance with manufacturer’s
specifications, or abuses other than ordinary use (ii) if the Product has been modified by
PURCHASER or has been repaired or altered outside the factory, unless the manufacturer
specifically authorizes such repairs or alterations; (iii) where manufacturer serial numbers, warranty
data or quality assurance decals have been removed or altered.
P-Com also reserves the right to make product improvements without incurring any obligation or
liability to make the same changes in Products previously manufactured or purchased. In no event
shall the manufacturer be liable for any breach of warranty in an amount exceeding the net selling
price of any defective Product. No person, including any dealer, agent or representative of P-Com is
authorized to assume for P-Com any other liability on its behalf except as set forth herein.
Nonpayment of any invoice rendered within the stated payment terms automatically cancels any
warranty or guarantee stated or implied. If any payment is due to the manufacturer for services
performed hereunder, it shall be subject to the same payment terms as the original purchase.
P-COM HEREBY DISCLAIMS ALL IMPLIED WARRANTIES ON PRODUCTS INCLUDING
WITHOUT LIMITATION, ALL IMPLIED WARRANTIES OF MERCHANTABILITY OR FITNESS FOR
A PARTICULAR PURPOSE. The warranties expressly stated herein are the sole obligation or liability
on the part of P-COM arising out of or in connection with the sale or performance of the products.
Products Manufactured by Others - For products not manufactured by P-COM, the original
manufacturer’s warranty shall be assigned to PURCHASER to the extent permitted and is in lieu of
any other warranty, express or implied. For warranty information on a specific product, a written
request should be made to the manufacturer.
IN NO EVENT WILL P-COM BE LIABLE TO PURCHASER FOR (i) REPROCUREMENT COSTS; (ii)
SPECIAL, INDIRECT OR CONSEQUENTIAL DAMAGES; (iii) ANY DAMAGES WHATSOEVER
RESULTING FROM LOSS OF USE, DATA OR PROFITS ARISING OUT OF OR IN CONNECTION
WITH THIS AGREEMENT, OR THE USE OR PERFORMANCE OF P-COM PRODUCTS,
REGARDLESS OF WHETHER THE CAUSE OF ACTION IS IN CONTRACT, TORT, INCLUDING
NEGLIGENCE, OR ANY OTHER FORM.
No action, whether in contract or tort, including negligence, arising out of or in connection with this
Agreement, may be brought by either party more than eighteen (18) months after the cause of action
has accrued, except that an action for nonpayment may be brought within eighteen (18) months of
the date of last payment.
PRODUCT COMPATIBILITY
While every effort has been made to verify operation of this product with many different communications
products and networks, P-Com Corporation makes no claim of compatibility between its products and other
vendors’ equipment. It is assumed that users have thoroughly evaluated this product’s performance in the
communications environment in which it will be used.
SAFETY
The following general safety precautions must be observed during all phases of operation and service of this
product. Failure to comply with these precautions or with specific warnings elsewhere in this Manual willfully
violates standards of design, manufacture, and intended use of the product. P-Com Corporation assumes no
liability for the customer’s failure to comply with these requirements.
This product must be grounded. In the event of a short circuit, grounding reduces the risk of electrical shock
by providing an escape wire for the current.
We recommend that you use preferred power—a dedicated power circuit with an assigned circuit breaker.
The product’s AC power cord ends in a three-pole grounding plug. Do not use a three-pole to two-pole adapter
with the plug. Verify that the outlet you intend to use is properly installed and grounded; the outlet used must
comply with the National Electric Code (NEC) NFPA70 (1990) in U.S.A. or other local and national or
international applicable code.
Do not install or operate this product in the presence of flammable gases or fumes. Operation of any electrical
instrument in such an environment constitutes a definite safety hazard.
No user maintained or adjustable components are present within this product. Do NOT attempt to open this
unit. Do not attempt to service this unit except under the direction of Customer Service. Only P-Com-authorized
service personnel should service this equipment. The potential for electrical shock exists within the enclosures
at all times unless they are unplugged.
Do not install substitute parts or perform any unauthorized modification to the product. Return the product to
the factory for service and repair to ensure that safety features are maintained. Prior to returning any product(s)
for repair, contact P-Com at the telephone numbers or address located in this Manual, and obtain a Return
Material Authorization (RMA) number.
Changes or modifications not expressly approved by P-Com Corporation can void the user’s authority to
operate this equipment.
SYSTEM GROUNDING
Direct grounding of the antenna, mast, and tower serves as protection from lightning strikes and static buildup.
A direct electrical connection should be made to a suitable grounding rod at the base of the tower or mast using
at least #10 AWG ground wire, or its equivalent, and non-corrosive hardware. For details and safety standards,
consult the appropriate local Electrical Codes or a similar document. Use lightning arresters in appropriate
places.
TOWER CONSTRUCTION
Compliance with local zoning and tower construction regulations is recommended when DataMetro II systems
require a tower. These regulations generally mandate that permits be obtained before any tower construction
begins. Check with local zoning and aviation authorities for more information.
FCC NOTICE TO USERS
This device complies with Part 15 of the FCC rules. Operation is subject to the following two conditions:
(1) This device may not cause harmful interference, and
(2) This device must accept any interference that may cause undesired operation.
Changes or modifications not expressly approved by P-Com Inc. can void the user’s authority to operate the
equipment.
FCC regulations require that this device be professionally installed by a person knowledgeable in electronics
and trained in the correct installation of this device.
All interface cables must be shielded.
CANADIAN DEPARTMENT OF COMMUNICATIONS COMPLIANCE
This Class B digital apparatus meets all the requirements of the Canadian Interference-Causing Equipment
Regulations. This digital apparatus does not exceed the Class B limits for radio noise from digital apparatus
as set out in the Radio Interference Regulations of the Canadian Department of Communications.

The P-Com DataMetro II is a wireless remote access router with
an embedded computing engine. The radio is based on direct
sequence spread spectrum technology, operating in the 2400
MHz to 2483.5 MHz RF band.
DataMetro II uses time division multiple access (TDMA) to
provide access to the wireless media. The Media Access Control
(MAC) protocol is implemented by hardware, providing high
performance throughput without software intervention.

The DataMetro II is easy to install and configure as a wireless
router. All software that controls the PC is included for the
network administrator. Initial configuration is implemented via
• a 12-bank set of DIP switches, or
• a Command Line Interface running on a terminal, or
• the Site Manager application running on a PC connected to the
DataMetro II unit through a local area network (LAN) or
through the public telephone network.
The DataMetro II offers wide area network connectivity when
cables cannot be used due to distance, physical obstructions, or

price constraints. The wireless network can be dynamically
reconfigured to provide new permanent or temporary services.
Adding or removing nodes does not affect network operation.
The DataMetro II lowers networking costs by combining routing
and wireless transceiver functions in a single package. It lowers
unit cost by using an embedded computing engine rather than an
external PC. It provides remote downloading of firmware and
provides password and hard-coded serial number protected
management. The Ethernet 10baseT port connects to the LAN.
The P-Com DataMetro II Model 320 and Model 1280 are
distinguished by data rate.

The DataMetro II provides bi-directional communication for
multiple WAN nodes. The wireless network can be configured to
one of three network topologies:
• point-to-point—where two nodes are communicating directly
with each other (see section Point-to-Point Topology on page 2-2)
• peer-to-peer—where all nodes in a network communicate
directly with one another (see section Peer-to-Peer Topology on
page 2-2)
• centralized (star)—where the node at the center of the network
acts as a switching device for communication between remote
nodes (see section Centralized (Star) Topology on page 2-3)

The term network topology refers to the logical layout of a network.
It defines how the network elements will communicate with each
other, how the information will be transmitted, and how the
information will be routed through the network.

Packet-based networks are most suitable for data that come in
bursts, such as networks that involve large-scale data
transmissions for multiple users at the same time. There is a
guaranteed minimum throughput for a packet-based network,
but the actual throughput realized by a packet-based network
node will depend on
• the number of users in the network, and
• how much traffic is being generated by each node at any given
time.
The advantage of a packet-based network is that multiple
transmissions can travel along the network at the same time,
using whatever path is appropriate to the routing from the source
to the destination.
The most significant characteristic of packet-based networks is
the wireless interface access protocols they use, such as
CSMA/CA (Carrier Sense Multiple Access/Collision Avoidance),
which can result in more efficient use of the aggregate bandwidth
by dynamically allocating throughput to nodes based on
demand.
P-Com DataMetro II supports Point-to-Point, Peer-to-Peer, and
Centralized (Star) packet-based network topologies. Each
topology has its own optimized wireless protocol.

In a packet-based point-to-point topology, two nodes are linked
directly. The most common application for this topology would
be the interconnection of two LANs. In Figure 2-1, the LANs are
connected via a pair of DataMetro II routers.
Figure 2-1 Point-to-Point Topology
The range and interference immunity that can be achieved with
packet-based point-to-point topology is maximized by the use of
highly directional antennas on both sides of the link.
DataMetro II applies native modification of the CSMA/CA
protocol for the point-to-point topology. Each node sends its
frame immediately after receiving a frame, in which case the
delay value is equal to zero. The node that sent the frame will
wait for a reply. If there is no reply, it will send the next frame
using the standard CSMA/CA protocol.

In peer-to-peer topology (unique to packet-based networks),
there are three or more nodes, any one of which can communicate
directly with any other node. Since each node has direct access to
every other node, the time delay for transferring data between
nodes is the least for this type of topology, unless WAN traffic is
very high. However, this also implies that each node must have a
clear communication path to every other node, that is, there must
be clear line of sight.
An example of a three node peer-to-peer topology is shown in
Figure 2-2 on page 2-3.

Centralized (Star) Topology

Figure 2-2 Peer-to-Peer Topology
In peer-to-peer topology, since all nodes need to talk to each
other, the range is dependent on the type of antennas used and
the local terrain. Longer ranges can be achieved by using
directional antennas with power splitters to connect to all sites.

In a Star topology, there is one radio at a central location
designated as a Base Station or Star Base, and several remotes
designated as Remote Stations or Star Remotes. The Star Base acts
as a switching device. The Star Remotes communicate with each
other through the Star Base.
A DataMetro II wireless network with centralized topology can
connect up to 127 wireless nodes. The MAC protocol used is a
combination of random and polling MAC protocols, with
positive Data Link acknowledgment that improves the reliability
of frame delivery.
Figure 2-3 on page 2-4 shows DataMetro II wireless router nodes
in a star topology.

Figure 2-3 Star Topology
A directional antenna can be used for the central site if all of the
nodes fall in the main lobe of the antenna pattern. Since the
remote sites need only communicate with the central site,
directional, high gain antennas can be used.
The range of a Star topology network can be increased if the
remote nodes are all located within a confined sector from the
central site. Communication between two remote sites must be
relayed through the central node.
Medium access contention on the Star Base is resolved by the
specific Star Base MAC protocol. The Star Remote sends the data
frame only when it gets permission from the Star Base. Each
frame regularly transmitted by the Star Base contains the PID
(polling ID) of the wireless cluster node. If a polled Star Remote
has a frame to transmit, it explicitly sends the frame to the Star
Base. The Star Base relays this frame to the Star Remotes
indicated by the DID (destination ID) of the original frame. A
polled Star Remote does not reply on the PID if it has no frame to
transmit.

Before you use a Data Metro II radio on the WAN, P-Com
recommends that you set up a basic radio configuration to make
sure the full WAN installation will proceed smoothly.
The basic configuration requires
• RF channel—all units in the WAN must use the same RF
channel. Separate WANs in the same geographic area may
need to use different channels. The DataMetro II Model 1280
provides nine channels; the Model 320 provides 14 channels.
• PN code—all units in the WAN must use the same PN code.
Different PN code sequences reduce interchannel and co-
channel interference between networks. The DataMetro II
provides eight PN codes.
• topology—the Data Metro II provides these topologies: peer-
to-peer, point-to-point, centralized (star base and star remote)
• reboot—to install the basic configuration
You can set up a basic radio configuration through one of three
methods:
• through twelve DIP switch positions
• through a terminal command line interface
• through the Site Manager software application

The P-Com Data Metro II radio can be configured through a
command line interface running on a terminal (or a PC running a
terminal emulation program).
Before connecting the terminal to the radio, configure the
terminal with the following settings:
• Baud rate = 9600
•Data bits = 8
• Parity = None
• Stop bits = 1
• Flow control = Hardware
If you are using a PC or laptop computer, refer to the operating
system documentation for instructions on how to configure and
run the terminal emulation program.

After power-on the unit will run a power-on-self-test (POST).
This test takes about 40 seconds to complete. Successful
completion of the POST causes the 7-bank LEDs on the front of
the radio to flicker before going to a steady state.
If you have successfully connected to the radio, the terminal will
display the 'DWD0HWUR! prompt and an initial message.

The P-Com Data Metro II radio can be configured through a
Windows-based software application call Site Manager.
Site Manager runs on an external computer connected remotely
to the DataMetro II unit over the LAN through the Ethernet port,
or over the public telephone network through the RS-232 port.
Site Manager is generally used by the network administrator for
both basic configuration of a DataMetro II unit as well as
advanced configuration of a wireless cluster of units. If you want
*In the example, XXXXXXXXXXXX is factory set and is unique to each radio.
