The ViPR radio is intended for use in the Industrial and SCADA market. The ViPR unit must be profes-
sionally installed and must ensure a minimum separation distance between the radiating structure and any
person of more than 74 in (188 cm) for UHF (406.1-512 MHz frequencies) or more than 86 in (218 cm)
for VHF (136-174 MHz frequencies). 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 ViPR radio uses a low power radio frequency transmitter. The concentrated energy from
an antenna may pose a health hazard. People should not be in front of the antenna when the
transmitter is operating.
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.
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
The required antenna impedance 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 communication.
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.

2.2.3 RF Path and communications range
The range of the ViPR radiomodem is dependent on terrain, RF (radio frequency) path obstacles, and an-
tenna system. To assure reliable communications, a competent professional should study the RF path to
determine what antennas are required and whether or not a repeater is needed.
2.2.4 Antennas
The antennas listed in Table 1, page 13 were tested and typed for maximum gain. These antennas are
FCC-approved for use with the ViPR product. Similar antenna types from other manufacturers are also
acceptable.
2.3 Network application
The ViPR radiomodem is suited to a variety of point-to-point or point-to-multipoint applications. This
section 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 allows for quick deployment of basic point-to-point and
point-to-multipoint networks with minimal configuration to all units on a same network. 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 links. Only one
radio model is needed because any ViPR unit can be configured for bridge or router mode, router gateway
(access point), remote station, or even as a combined store-and-forward remote with a local drop.
2.3.2 Connections
The connections required are shown in Figure 3 below and in Figure 4 on the next page. While serial
and/or Ethernet RTU or PLC are shown in the diagrams, master stations often use a PC running an appli-
cation designed to communicate with remote RTUs or PLCs, or intelligent controllers.
120 40520-100a ViPR User Manual
17
Figure 4 shows a common connection scenario. The TX/RX antenna is required for basic operation. The
power connection allows for a wide range of input DC power, whether the user system is a nominal 12 or
24 VDC supply system. A setup PC can be connected via the serial port, allowing for setup and configu-
ration of the ViPR unit as well as 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. The Ethernet port allows end users
Ethernet-capable RTU or PLC to be connected.
Figure 3 - Basic Setup
Figure 5 shows the various connection opportunities for the ViPR radiomodem. The TX/RX antenna is
required for basic operation.
Figure 4 - Setup using Switch (or Hub)
2.4 Selectable Data Rates
Switchable data rates allow optimizing installations for highest throughput or maximum range. The so-
phisticated DSP modem gives optimal performance in either mode, whether a short-range LAN extension
or long-range link.

2.5 Point to Point System
Shown below are typical “point to point” and “point to multipoint” connections between ViPR units. The
connections indicated allow for either Ethernet or serial interfaces. The Ethernet connection provides
Ethernet IP connectivity for network devices. In bridge mode, all the network devices are on the same IP
Subnet. In router mode, the Ethernet connection on Master unit and the remote(s) use different IP Sub-
nets. A hub or switch may be used to allow multiple Ethernet devices to connect to the ViPR radio-
modem. Serial connections are transparent pass-through connections, allowing the use of legacy serial
devices in the ViPR product environment.

3. Physical Description
Figure 7 - ViPR Front Panel
The front panel only has connections and indicators. They are:
• One standard RJ-45 auto-sensing 10/100 UTP Ethernet connection with Auto-MDIX. Supports
direct 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 300 to 115,200 are supported. ViPR units are
factory set (default) for 115,200 b/s, 8 bits, no parity, and 1 stop bit.
• The antenna connector for the transceiver is a female 50-ohm TNC type.
• 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.

DCD (pin 1) handling by ViPR unit UART
• Asserts the DCD signal while sending data on the UART
• Negates the DCD signal when it no longer has data queued up for TX on the UART
DTR (Data Terminal Ready) (pin 4) signal handling by ViPR UART - Depends on the serial port's con-
nection control mode.
The connection control mode dictates how the ViPR establishes/breaks the connection (referred
to as "session") between the ViPR serial ports and the selected ViPR service (CLI, Serial/RF
bridge, Online Diagnostics, etc.)
• Permanent (3-wire) connection control - In this mode, the session is permanently established, so
the ViPR ignores the status of the DTR signal.
• Switched (DTR bringup/teardown) connection control - In this mode, the ViPR monitors the
status of the DTR signal.

- Upon DTR assertion: the session in established (bringup) phase
- Upon DTR negation: the session in closed (teardown) phase
CTS (Clear to Send) (pin 8) signal handling by the ViPR UART
• If CTS-based flow control is not used, always asserts CTS
• If CTS-based flow control is used:
♦ Asserted – If level of unprocessed data in internal RX buffers is below a threshold water-
mark
♦ Negated – If level of unprocessed data in internal RX buffers is above a threshold water-
mark

3.2 Diagnostic Connections
The ViPR units continually monitor and report on their environmental and operating conditions. The di-
agnostic information is in TCP format and is available via any telnet session to port 6272.
Transmission of online diagnostics may be enabled or disabled at any station or stations without affecting
their ability to communicate with other stations. Diagnostics can be sent anywhere, including being back
hauled. Back hauling adds to the network traffic flow and must be taken into account in designing a net-
work. If a return flow is necessary, it needs to be reduced substantially to have a minimal effect on the
network as described in section 3.2.1.
The ViPR radiomodem can support up to 4 diagnostics socket connections at once. This may be used, for
instance, to carry out monitoring at a main office and at up to three separate field locations. It is also pos-
sible that one of the four connections use a serial port instead by enabling it on the ViPR’s web browser
interface.
More 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 traveling to the other station.
3.2.1 Parameter
Adjusting the return diagnostics flow is done via parameter. This parameter indicates that only one out of
every x packets delivered will generate an online diagnostic message. The “thinning value” can be ad-
justed using the web interface (see paragraph 4.8.2.5) and set as follows:
♦ 0 off
♦ 1 every packet delivers a diagnostics message
♦ 1000 every 1000th packet delivers a diagnostic message
3.2.2 Output Format
Output format is man / machine-readable, ASCII, comma-delimited format. Reader program used (or
written) must decode the “type field” and check for type 0 as more types will be released in future. This
will ensure that no changes will be required to the user online diagnostic reader program when the ViPR
radio modem gets updated. The fields are:
♦ IP or MAC address: Depends if unit is in Bridge mode or in Router mode
• MAC: Hex numbers format [00:01:02:03]
• IP: Dotted decimal format [111.222.333.444]
♦ Type of report: Decimal number (n) that identifies the report as a “type n”
♦ # of fields: Decimal number indicating number of comma-delimited fields to follow
♦ Thinning value: Number of data packets before a diagnostic message is delivered
♦ Volts: Decimal indications in decivolts when source is DC input (125 for 12.5V)
♦ Temperature: Decimal internal unit temperature in Celsius degrees
♦ Packet error rate (or PER): 0 or negative decimal value

4.8.3.3.1 NAT Overview
The purpose of the “Network Address Translation” (NAT) protocol is to hide a private IP network from a
public network. The mechanism serves both as a firewall function and to save IP address space.
Figure 32 - Basic NAT Operations
The source address of packets transiting from the private network to the public network gets translated by
the NAT enabled device. The original IP source address gets replaced by the NAT enabled device’s own
IP address (address of the outgoing interface). The NAT module creates an address translation table that
is used when traffic is coming back from the public network to the private network.
In our example Host 1 sends a packet to Host 2. The Host 2 device does not see the private IP address of
Host 1. When Host 2 sends a reply to Host 1, he uses the destination IP address 172.31.1.1, this gets
translated back to the appropriate destination IP address by the NAT enabled device.
NAT does a lot more then just translation of the IP source address. NAT does also some translation de-
pending on the IP protocol. For the UDP and TCP protocol NAT, will also translate the source port num-
bers. Special handling is also done for other more specific protocol like FTP.

4.8.3.4.1 IP Broadcast/Multicast Overview
When an IP packet needs to reach more then one unit, the destination address can be set to either a broad-
cast address or a multicast address.
BROADCAST - There are two types of IP broadcast address:
• Directed broadcast
A directed broadcast address is an IP address where the host portion is all ones (for instance
172.30.1.255 is the directed broadcast address for the network 172.30.1.0/24, 172.30.1.207 is the
directed broadcast address for the network 172.30.1.192/28).
Note:
Routing equipment (to prevent broadcast storms) do not by default forward limited
broadcast packets (255.255.255.255). On the other hand, directed broadcast packets are
by default forwarded because these packets are routable like any other unicast packets.
• Limited broadcast
The limited broadcast address is 255.255.255.255.
MULTICAST - IP multicast addresses are in the range 224.0.0.0 to 239.255.255.255. These addresses
are used to represent logical groups of units that may or may not reside on the same networks.
Multicast is used when “one-to-many” communication is required. For instance, a radio station might of-
fer a music channel on the Internet in real time. To receive the music a user (host) must know the multi-
cast group (multicast address) used by the radio station and add itself as a member of this group. In the IP
realm, a host uses the IGMP protocol to do this. The routers inside the Internet are using IGMP and other
multicast routing protocol to build the proper path from the sender to the receivers (a tree like path is
formed from the sender to the receivers).

4.8.3.4.1.1 Broadcast
Figure 38 - Broadcast Window Detail
DIRECTED BROADCAST
Each interface of a unit has its own IP address and netmask. From the IP address and netmask, it is easy
to calculate the broadcast address associated to the interface. For instance, if the Ethernet interface ad-
dress of an ViPR unit is 172.30.1.1/24 and the RF interface address is 10.0.1.2/24, then the broadcast ad-
dress of the Ethernet interface is 172.30.1.255 and the broadcast address of the RF interface is 10.0.1.255.
The “Directed Broadcast” radio buttons let the user select whether the unit must forward or not directed
broadcast packets. Upon reception of a directed broadcast packet, the unit takes the following actions:
If the directed broadcast address match with one of the unit’s interface broadcast address:
• Keep a copy for itself (pass to internal applications, if any).
• If directed broadcast packets can be forwarded:
Forwards the packet according to the routing table.
• If directed broadcast packets cannot be forwarded:
Silently discards the packet.

Note:
Occasionally, the unit cannot determine that the packet is actually a directed broadcast. In such a
case, the packet is normally routed.
LIMITED BROADCAST
The “Limited Broadcast” radio buttons let the user select whether the unit must forward or not limited
broadcast packets. Upon reception of a limited broadcast packet, the unit takes the following actions:
• Keep a copy for itself (pass to internal applications, if any).
• If limited broadcast packets can be forwarded:
Sends a copy of the packet out of all the interfaces at the exception of the interface where the packet
was received.
• If limited broadcast packets cannot be forwarded:
Silently discards the packet.
4.8.3.4.1.2 Multicast
In an ViPR environment, an outside host (Sender) might be interested in sending multicast packets to any
one of the following groups:
• “All Remote ViPR” group.
• Various “Remote Host” group.
The main ViPR unit is directly connected to the outside network. ALL multicast groups MUST be identi-
fied in the main ViPR unit because it uses IGMP to register the memberships to the multicast groups on
behalf of the other units and Hosts (Remote ViPR units, Remote Hosts).

5. Optimization & Troubleshooting
After original setup is complete, you may wish to maximize performance by first optimizing the Airlink
(or RF link) and then optimizing the ViPR radio modem to function in the resulting environment.

5.1 Maximizing TCP/IP
If after optimizing the airlink there still appears to be an unexplained speed loss, you can look at maxi-
mizing TCP/IP.
TCP/IP throughput can be tricky to measure as performance is related not only to the RF link, but how
well flow control is implemented in the TCP/IP stack and how each application is designed. The ViPR
has been highly optimized with this in mind. When the TX/RX LED flashes amber, this not only indicates
that data is moving but also indicates (by the LED OFF periods) when data is not moving across the RF
network at full rated speed. If you get flashing RED indications on the TX/RX LED, RF reception prob-
lems are present and causing some loss of throughput. OFF periods indicate that the application has not
presented data to the ViPR radio modem.
Using different client/server combinations or applications may show improvements. For instance, one
FTP server may work 30% faster than another, simply because the buffer management is quicker to re-
spond or has bigger message buffers – yet run at nearly the same speed over a pure Ethernet (no RF) link.
Network Address Translation (NAT), payload data compression and encryption have little effect other
than adding a small latency to the flow of traffic.
The TDD mode should be left enabled unless highly specialized protocols are being run. Sometimes,
these protocols and TDD interfere which each other and may run somewhat faster with TDD disabled.
5.2 Maximizing via Setup Pages
Further performance optimization can be done via the User Interface Setup pages. The fundamental ad-
justments described in the following paragraphs can be changed singularly or in conjunction with each
other
Note: Data Compression (section 4.8.3.5 above) should only be OFF while testing, thereby eliminating
performance differences due only to different compression rates.
5.2.1 Use Router Mode
Selecting Router mode (see section 4.8.2.1) is highly recommended when running over a weak RF link.
This mode ensures that several levels of retry mechanisms are at work, each optimized to minimize TCP
flow control delays or even preventing a dropped TCP/IP link. It requires some IP route planning to and
from the ViPR units but is well worth the increase in link stability over the simpler bridge mode
5.2.2 Reduce RF network bit rate
Normally the system is able to utilize the normal bit rate of xxK (see section 4.8.2.3). If you have a very
low signal level (-90 dBm or less) or the RF signal levels are close to an elevated noise floor level, you
can try running at xxK instead of xxK (changeable on the fly without a reset). It could result in better
overall performance.
5.2.3 Increase OIP Retries Limit
Only available in Router mode, OIP Retries Limit is normally set to two (2). Gradually increasing it up to
five (5) in extreme cases, may provide a slow but reliable link when none was possible with weak signals.
Use in conjunction with a xxK network bit rate.

5.3 Troubleshooting Tools
5.3.1 Network Connectivity
• PING
The ping command determines whether a specific IP address is accessible. It works by send-
ing a packet to the specified address and waiting for a reply. It is useful for troubleshooting
“end-to-end” reachability, network connectivity, and network latency.
Available for MS-Windows 9x, ME, NT, 2000, and XP as well as Unix & Free BSD.
EXAMPLE:
ping 192.168.204.1 displays the response with turn around time in milliseconds.
• TRACERT (WINDOWS)
The tracert command is used to visually see a network packet being sent and received and
the number of hops required for that packet to get to its destination.
Available for MS-DOS 6.2, MS-Windows 9x, ME, NT, 2000, and XP.
Note:
Users with MS-Windows 2000 or XP who need additional information on network la-
tency and network loss may also use the pathping command.
EXAMPLE
tracert www.yahoo.com at the command prompt displays the intermediate routers be-
tween local host to the www.yahoo.com site.
120 40520-100a ViPR User Manual

5.3.2 Configuration Information
• WINIPCFG (WIN95/98), IPCONFIG (WIN2K) or IFCONFIG (UNIX)
Ipconfig is a DOS utility, which can be used from MS-DOS or a MS-DOS shell to display
the network settings currently assigned and given by a network. This command can be util-
ized to verify a network connection as well as to verify network settings.
Available for MS-DOS, MS-Windows 9x, ME, NT, 2000, and XP.
EXAMPLE
ipconfig /all at the command prompt displays the Ethernet MAC address, IP address,
IP netmask, default IP gateway, DNS server… information.
• ARP
View and update the system ARP table
The Address Resolution Protocol (ARP) is used with the IP protocol for mapping a 32-bit
Internet Protocol address to a MAC address that is recognized in the local network specified
in RFC 826. Once recognized the server or networking device returns a response containing
the required address.
Available for MS-Windows 9x, ME, NT, 2000, and XP.
EXAMPLE
arp -a displays all entries in the ARP cache. Useful in manipulating ARP caches.
• ROUTE
View and update the system routing table
The function and syntax of the Windows ROUTE command is similar to the UNIX or Linux
route command. Use the command to manually configure the routes in the routing table.
Available for MS-Windows 9x, ME, NT, 2000, and XP.
EXAMPLE
route ? displays help
route print displays the routing table
5.3.3 Statistics Information
• NETSTAT (WINS & UNIX)
The netstat command symbolically displays the contents of various network-related data
structures, i.e. IP, TCP UDP …
Available for MS-Windows 9x, ME, NT, 2000, and XP.
EXAMPLE
netstat ? displays help
netstat -a display TCP and UDP connections and listening ports information

5.4 Firmware Upgrading
The ViPR radiomodem firmware is field-upgradable using the unit’s Ethernet port. The process involves
connecting to the IP address of the mobile from a host PC and transferring the firmware files via an FTP
program.
5.4.1 Procedure
1. Using a file decompression program, such as WinZIP™ or WinXP’s right-click & select the “Expand
to…” option, expand the contents of the firmware upgrade package to a directory of your choice on
the host PC.
Warning:
Be aware that base and mobile’s firmware archives are often distributed at the same time. Files
intended for the ViPR radiomodem are labeled in the form ViPR_Vx.x_Rx.xx.zip. Be
careful not to transfer firmware into the wrong unit!
2. Using an FTP program of your choice, establish a connection to the mobile IP address. Please refer to
paragraph 4.8.4.1 for “Username” and “Password” usage.
3. Transfer all the files in the upgrade package. Occasionally, long pauses, on the order of 30 to 45 sec-
onds, are possible when storing the file in the unit’s flash file system.
4. Once the file transfer is complete, cycle the mobile power and allow the unit to boot. The unit should
return to the state that it was in when the update was started.
Note:
After resetting, the PWR LED remaining lit steady amber or red indicates the FTP transfer was
not successful or that the firmware is corrupt. Please contact Dataradio system engineering for as-
sistance.

5. Verify the integrity of the newly transferred files.
a) Connect to the mobile’s IP address using an Internet browser such as IE (5.0 or later) or Mozilla.
b) Enter the user name and password (in the usual manner) and allow the Welcome page to load.
c) In the left pane, click on Unit Status. The Unit Identification and Status pane should display the
newly upgraded firmware in its Banner (should correspond to the upgrade package version) and the
H/W Status should also show Ok.
d) In the left pane, click on Maintenance, then on Package Control. Wait a few moments for the re-
sults to display. Figure 53 shows a “Pass” result indication.
Figure 56 - Sample FTP program
5.4.1.1 File Integrity Failure
