SETUP AND CONFIGURATION
These instructions allow you to set up a Viper SC+ IP Router to verify basic unit
operation and experiment with network designs and configurations. To eliminate
unnecessary disruption of traffic on the existing network while you become familiar with
the Viper SC+, you should use a network IP subnet address that does not overlap with
subnets currently in use in your test area.
Antenna & Attenuator Connection
An Rx/Tx antenna is required for basic operation. Assemble antenna and connectors
as shown in the accompanying figure. Antenna and connectors are sold separately.
Note: It is important to use attenuation between all demo units in the test network to reduce the
amount of signal strength in the test environment.
Device Connections
Refer to the diagram below for proper device connections.
Connect an Ethernet cable to the LAN port of the Viper SC+ and connect the other end into the
Ethernet port of your PC.
Primary power for the Viper SC+ must be within 10-30 V DC and must be capable of providing:
•10 W supply for Tx at 1 W
•40 W supply for Tx at 5 W or
•60 W supply for Tx at 10 W
Viper SC+ Demo kits include a power supply with spring terminals. Observe proper polarity when
connecting the cables to the power supply. The white wire must be connected to the red wire or B+
supply, as shown in the above figure.
Accessing the Viper SC+ Web Server
The Viper SC+ is configured via a Web-browser interface and contains a DHCP server which will
automatically assign an IP address to your PC, however in some cases it may be necessary to change
the network settings on the PC to accept the IP address assigned by the Viper DHCP server.
Step 1 Enable a network connection with the following LAN settings. In the Internet Protocol
(TCP/IP) Properties window, select Obtain an IP address automatically and Obtain DNS server
address automatically. Click OK and close.
Step 2 Open a Web browser and enter 192.168.205.1 in the Address bar. When the connection
Login window appears, enter the Username: Admin and the Password: ADMINISTRATOR (both
Admin and ADMINISTRATOR are case-sensitive) and click OK.
Viper SC+ Web Interface and Setup Wizard
Once you have logged in you will see the Home page of the Viper Web Interface as shown in the
following figure. Arranged vertically on the left side is the main navigation menu.
For quick setup, select Setup Wizard, the bottom selection of the main menu (to the left). The
introductory page of the Viper SC+ Setup Wizard is displayed as shown in the following figure. Read
the instructions carefully.
The Setup Wizard consists of five (5) steps. Each step is presented as a single page with a few simple
options to fill in or select from. Each of the five pages for each step of the Setup Wizard contain the
basic configuration settings that are most required to select or change to set up the Viper SC+ IP
router for specific functionality.
Instructions for each of these steps are provided on the web page for the step.
The Setup Wizard steps are as follows
Step Identification and function: Station Name and Mode settings: Station Name, IP
Forwarding Mode, Relay Point, Access Point, Multi-Speed Mode.
Step Network Address & Subnet: IP Address, Network Mask, Default Gateway.
Step Radio Settings: Bandwidth, Data and Control Packet Bit Rate, Rx & Tx Frequency ranges ,
Tx Power.
Step Encryption: Enable or Disable, and Encryption Pass Phrase.
Step Setup completion: Apply / Save Configuration; if necessary, reboot / reset Viper.
Note: Some settings (indicated by a yellow alert symbol ) in the Setup Wizard web pages require
a reset of the Viper before they will take effect. If you change any of these settings, be sure to reboot
the Viper when you have finished the Setup Wizard.
Setup Wizard Quick Setup
Enter the following in the Setup Wizard for quick setup. Click Next as you complete each page in
sequence. (You can click Previous to review settings in a previous page if needed.)
Step Assign a unique Station Name and select how unit will function.
- Station Name: Assign a unique Station Name
- IP Forwarding Mode: Bridge mode
- Relay Point: No
-Access Point: No
- Multi-Speed Mode: Disabled
Step Default configuration —To monitor or change configuration remotely, each unit
requires a unique IP address. When configuring more than one unit, be sure to
increment IP addresses. (Enter this address in the browser after reset.)
- IP Address: 192.168.205.1 is the default setting; see above.
- Network Mask: 255.255.255.0
-Default Gateway: 0.0.0.0
Step Verify FCC License before completing this step
- Bandwidth: Select channel bandwidth from drop-down menu
- Data and Control Bit Rate: Select rate from a down menu
- Rx Frequency: Enter Rx Frequency
- Tx Frequency: Enter Tx Frequency
- Tx Power: Enter 5 W
Step Viper SC+ offers AES-128-bit encryption to protect your data from intrusion. We
recommend encryption be enabled for your wireless network. The encryption phrase /
key must be the same for all devices on your network.
- Encryption: Enabled
- Encryption Pass Phrase: Enter an encryption phrase.
Step Click Done. Your unit is now functioning in Bridge Mode.
Note: If you changed any parameters marked with the yellow alert symbol ( ) you must power-
cycle the unit. Use the Reset link provided.
Check for Normal Operation
To simulate data traffic over the radio network, use the PC connected to the Viper SC+ Ethernet
port to Ping each unit in the network multiple times. For more information about configuring the
Viper SC+, refer to the Viper SC+ User Manual (PN 001-5008-000).
