Page 2 O O O O N N N N Thank you for purchasing a Pegasus Wireless ACR-201-G. This User’s Guide will walk you through the setup and installation of your device, as well as offering advanced configuration options. If you feel that you do not have a solid background in wireless technology, you will find a handy glossary of common terms in Appendix C: Wireless Glossary.
Page 3 The IP Bridging Mode, when enabled, allows the sharing • of the Station Radio by multiple computers By connecting a device or computer to the ACR-201-G, you create a pure Maximum 54 Mbps data rate and automatic selection of •...
Page 4: Security Protocols
Security Protocols The ACR-201-G supports the WPA (Wi-Fi Protected Access), TKIP (Temporal Key Integrity Protocol), and WPA-PSK (Pre-Shared Key) security protocol in addition to the standard 64- and 128-bit WEP encryption to provide the highest degree of security to your wireless network.

If you do not wish to configure the device’s settings, simply plug the ACR-201-G into your host device, and you can start using it right away. See Chapter 1: Installation and Setup for more information.
Page 6 U U U U P P P P This chapter will walk you through the initial installation and setup of your ACR-201-G device. While you go through this chapter, please refer to Appendix C: WiFi Glossary if you come across any terminology which is unfamiliar to you.
Page 7 R R R R E E E E Installing the ACR-201-G is a simple procedure. There are three cables which may need to be connected to the ACR: a black power cable, a white ‘Straight-through’ Ethernet If you are running the ACR-201-G off of cable, and a blue ‘Crossover’...
Page 8 You will use this cable if the IP Bridging feature is enabled. This allows you to enable multiple devices to use the ACR-201-G for access via a hub or a switch. To do this, use the blue crossover UTP cable to connect the ACR-201-G to the switch or hub.

Ethernet port. Check your Ethernet cable connection, making certain that the cable is seated well in both the ACR-201-G’s Ethernet port, as well as in the host item’s Ethernet port. Remember that the white Straight-through cable is used for connecting it to a host computer, printer, etc. and the blue Crossover cable is used for connecting it to a network hub or switch.
Page 10 ACR-201-G User’s Guide For laptop users, once the ACR-201-G radio unit works properly, the unit can be secured at the top of the laptop display by the provided radio clip as shown in the following figure. Revision 1.02 10/52...
Page 11 A Configuration Utility is built in to the ACR-201-G for changing the configuration settings. This software will allow you to change settings on the ACR-201-G, and can be accessed with any standard internet browser software. To use this, you do not need to be connected to the internet.

Page 13 When you open the program through your browser, you will see six tab links at the top of the page. These pages are hard-wired directly into the ACR-201-G device; you do not need to be connected to the internet to use them. Details of each page follow. Note that because of varying operating systems and browser software, the Configuration Utility pages may look slightly different from the screenshots.
Page 14: Device Name
1. Device Name: Device Name This is the name that the ACR-201-G will use to identify itself to external configuration and IP-address-finding programs. This is not the same as the SSID. It is okay to leave this blank if you are not using these programs.
Page 15 Select ‘Static’ to use the IP settings specified on this page. IP address This shows the current IP address of the ACR-201-G wireless device. This allows the user to set a static IP address to the Wireless bridge station. This IP address is only used for accessing the built-in configuration utility.

(http://pegasuswirelesscorp.com/support/downloads.html). Select the firmware to update and download it to your computer. Once you’ve done that, click on “Browse” (from within the ACR-201-G’s configuration utility) to select the correct firmware file, then click on upload to complete the upgrade. Info The Info Page shows all the current setting of the ACR-201-G.

Page 22 ACR-201-G User’s Guide Channel The channel option is only available when the ACR-201-G is in Ad-hoc mode. In Infrastructure mode, the ACR-201-G would use the channel of the connected access point. If you experience interference (e.g. lost connections or slow data transfers) you can try different channels to see which one is the best.

ACR-201-G User’s Guide • “802.11 b/g Mixed Mode”: This allows the radio units to connect to either 802.11b or 802.11g networks • “802.11 b/g Mixed Mode Long”: A long preamble provides universal compatibility for devices connecting to the Access Point...
Page 24: Wep Configuration
ACR-201-G User’s Guide PSK Pass-phrase Using the radial button, select the format type for your pass-phrase. The pass-phrase can be entered in either ASCII or HEX format. • ASCII format must be a minimum of 8 characters to a maximum of 63 characters.
Page 25 ACR-201-G User’s Guide Default WEP Key to Use Select the key to be used as the default key. Data transmissions are always encrypted using the default key. The other keys can only be used to decrypt received data. Deny Unencrypted Data Check this field when the WEP is enabled to deny unencrypted data.
Page 26: Advanced Wireless
To activate the Bridging mode, the user needs to select the WLAN Bridge option to allow multiple clients connecting to an ACR-201-G unit. If WLAN Client option is selected, the ACR- 201-G unit can connect to only a single client.
Page 27 To minimize this, the ACR-201-G has the ability to complete a “Request to Send” (RTS) and “Clear to Send” (CTS) process prior to sending the real data. This helps to reduce corruption and transmission delays of the real data.
Page 28 The following chapter includes information to assist you if something goes wrong with your ACR, or it does not work in the way in which you think it should. Before contacting Pegasus Wireless Technical Support please review the following scenarios thoroughly.
Page 29 • Make sure that a target radio, an Access Point or another Station is turned on and operating properly. • If the “Signal Strength” is less than 20%, the distance between the ACR-201-G and the targeted radio (an AP or another Station) may be too far. Decrease the distance and clear any ‘line of sight’...
Page 30 Ethernet connection is questionable. • Make sure the ACR-201-G is properly attached to the host computer/device. • Make sure that the Ethernet cable connecting the ACR-201-G and the host device meets at least the CAT-3 standard. • If you are using the cables provided for the device, please confirm that you are using the white Straight-through cable if the host device is a PC or the blue Cross-over cable if the host device is a hub or switch.
Page 31 ACR-201-G User’s Guide • Resetting or re-powering the host with the ACR-201-G turned on may be necessary in order for the ACR-201-G to “learn” the MAC address of the host computer. P P P P O O O O O O O O...
Page 32 However, sometimes it may be necessary to do a “hard” reset of your ACR-201-G unit. To do this, you will need a blunt instrument to reset your ACR-201-G back to its factory default settings. We recommend an unfolded paper clip, or other similar thin, blunt, sturdy device for this purpose.
Page 33 ACR-201-G and other Pegasus Wireless Corportation products quite simple. The Device Manager can help locate and return all Pegasus Wireless Corporation 802.11g devices that it can find hooked up to a network– whether these are hardwired or connected to the WLAN.

IP Address An IP address is a 32-bit number that identifies each sender or receiver of information sent across the Internet. An IP address has two parts: the identifier of a particular network on the Internet and an identifier of the particular device (which can be a server or a workstation) within that network.
Page 48 ACR-201-G User’s Guide A Local Area Network is a communication network that serves users within a defined geographic area (such as a single building). The benefits include the sharing of Internet access, files, and equipment, such as printers and storage devices. Special network cabling (100/10BaseT) is often used to connect the PCs together.
