Introduction
Overview of the Vivato Wi-Fi AP/Bridge
The Vivato Wi-Fi AP/Bridge provides continuous, high-speed access between IEEE 802.11a/b/g wireless
clients and wired Ethernet networks. It is an advanced, standards-based solution for wireless networking in
indoor areas. The Vivato Wi-Fi AP/Bridge enables zero-administration wireless local area network (WLAN)
deployment while providing state-of-the-art wireless networking features.
The Vivato Wi-Fi AP/Bridge provides the strongest security, ease-of-administration, and industry standards
— providing a standalone and fully-secured wireless network without the need for additional management
and security server software.
What’s Inside the AP/Bridge?
Inside the AP/Bridge is a Wi-Fi radio system and a central microprocessor that coordinates all activities.
The AP/Bridge contains two wireless interfaces. Each interface supports 802.11a, 802.11b, and 802.11g
operation. Two removable 2.2 dBi omnidirectional antennas are included that thread into the VA4200’s RP-
TNC (male) connectors.
The AP/Bridge boots from Flash ROM that contains firmware with the configurable, runtime features
summarized in “Overview of the Vivato Wi-Fi AP/Bridge” on page 16.
As new features and enhancements become available, you can upgrade the firmware to add new functions
and performance improvements to the AP/Bridges that make up your wireless network. (See “Upgrading
the Firmware” on page 80.)
The following sections list features and benefits of the Vivato Wi-Fi AP/Bridge, and describes the operation
of the front panel indicators and rear panel connectors.

Power LED - Illuminated but not blinking indicates that the VA4200 is powered on and is booting up. Blinking
indicates that the boot sequence has completed.
LAN LED - Illuminated but not blinking indicates a connection, but no link activity. Blinking indicates link
activity. Not illuminated indicates no recognized connection to a device.
Wireless LEDs - When off, indicates that the corresponding wireless interface (0 or 1) is disabled. When
blinking, indicates that the corresponding wireless interface is enabled. LED color indicates the current
802.11 mode used on that interface: green = 802.11b or 802.11b/g mode, amber = 802.11a mode.
Rear Panel Connections
Antenna connectors - Two RP-TNC (male) connectors.
Power - 12 VDC power connector. Center conductor is positive (+). Power supply plug required: 2mm pin
opening x 6mm outside diameter.
Reset - Using the end of a paper clip or other small shaft, quickly press and release the recessed button to
reboot the VA4200 using the last saved configuration. Holding the button in for approximately four seconds
causes the current configuration to be deleted and reboots the VA4200 using the factory default
configuration.
LAN RJ-45 10/100 Base-T Ethernet port. This MDI-MDIX auto-crossover and auto-sensing port is enabled
by default, and remains enabled unless you disable it during configuration. This port can also be used to
provide power to the AP/Bridge using an IEEE 802.3af-compliant power over Ethernet (PoE) device.
Category 5 (CAT-5) cabling to the VA4200 should be limited to a maximum length of 100 meters.
RS232 Serial (DB-9, male) - This serial communications (console) port provides direct control access to the
AP/Bridge’s operating system. This port is not used to perform any regular AP/Bridge operations, but is
provided to allow future operations, such as bootloader updates. The following are the required
communication settings:
• Baud: 9600
• Data bits: 8
• Parity: None
• Stop bits: 1
• Flow control: None
What’s Next?
Determining the best location for the VA4200 AP/Bridge requires careful planning and consideration. Refer
to “Installation” on page 32.
After mounting the AP/Bridge, read through the “PreLaunch Checklist: Default Settings and Supported
User/Client Platforms” on page 20 and then follow the steps in “Quick Steps for Setup and Launch of Your
Wireless Network” on page 26.

PreLaunch Checklist: Default Settings and Supported
User/Client Platforms
Before you power-up a new AP/Bridge, review the following sections for a quick check of required
hardware components, software, client configurations, and compatibility issues. Make sure you have
everything you need ready to go for a successful launch and test of your new (or extended) wireless
network.

Vivato Wi-Fi AP/Bridge
The Vivato Wi-Fi AP/Bridge is a wireless communications hub for devices on your network. It provides
continuous, high-speed access between your wireless and Ethernet devices in IEEE 802.11a, 802.11b,
and 802.11g modes.
The Vivato Wi-Fi AP/Bridge offers a multiple service set identifiers (SSID) feature that allows it to be
configured to provide several separate wireless networks, each using its own type of security. SSIDs use
virtual local area networks (VLANs) to separate network traffic.
