2YHUYLHZ 1 This manual describes how to install both the Savi RF Relay model 100 (RFR-100) and the Savi RF Relay model 200 (RFR-200). Both models provide wireless links among readers or between readers and a host computer. The RFR-100 connects to RS-485 networks, while the RFR-200 connects to LonWorks® networks. 6DYL 5) 5HOD\ 5)5 DQG 5)5 ,QVWDOODWLRQ *XLGH

,QVWDOODWLRQ 2 Installing the Savi RF Relay requires pre-planning your hardware needs to match your site and application. Discuss site-specific issues with your Savi customer service representative. The Savi System Installation Guide (Savi part number 805-00968-010/ order number JDM-1004) describes the overall process of planning an RFID network. This chapter describes the RF Relay installation process. To comply with FCC Section 1.
1HWZRUN 3ODFHPHQW 1HWZRUN 3ODFHPHQW Two Savi RF Relays bridge a minimum distance of 2.4 kilometers (1.5 miles) line-of-site as a wireless connection between a host computer and a SaviReader network, or between two sub-networks of SaviReaders within a network. Determine in advance where you will need to use Savi RF Relays to complete your Savi System, and then identify power sources, installation locations, and where to run cables.

1HWZRUN 3ODFHPHQW 0RXQWLQJ WKH 5HOD\ &RPSRQHQWV As you decide where to mount RF Relay components in relation to each other, keep in mind that the up/down converter connects to the NEMA enclosure through a coaxial cable with a maximum length of 153 dm (50 feet). The up/down converter (model UDC2.4B-0C only) connects to the antenna filter through a 46 cm (18 in.) coaxial cable. The up/down converter model UDC2.4C-0C connects directly to the antenna using the 61 cm (24 in.) coaxial cable.
1HWZRUN 3ODFHPHQW 0RXQWLQJ WKH $QWHQQD Be sure to mount the antenna so that its radiating element is clear of obstructions. Note: Note that the antenna is not grounded; therefore Savi recommends that you install a lightning-protection device in your system.

9HULILFDWLRQ 9HULILFDWLRQ To determine whether RF Relays have been installed correctly, follow the steps below to perform a simple test. » To verify installation: 1. Following the procedure described in the previous section, connect one RF Relay to a SaviReader. 2. Connect a second RF Relay to a host computer. 3. From the host computer, use Savi Asset Manager (SAM) software to perform a check-status event. If the relays are installed properly, the reader will return its status to the host computer.
0DLQWHQDQFH 3 With minimal care, a Savi RF Relay should perform flawlessly. However, in the event that a problem with an RF Relay occurs, the procedures in this chapter should help you troubleshoot it. Changes or modifications to the equipment that are not expressly approved by Savi Technology could void the warranty and the authority to operate the equipment. Using the equipment in a manner not specified by the manufacturer might impair the protection that the equipment provides. 6DYL 5) 5HOD\ 5)5
5HSDLU DQG 0DLQWHQDQFH 5HSDLU DQG 0DLQWHQDQFH The Savi RF Relay is designed to need very little maintenance. Savi RF Relays are manufactured with quality components and are thoroughly tested before delivery. As in any outdoor networked system, exposed RF Relay components need to be checked occasionally for physical damage. Periodically check cables and enclosures that are exposed to the elements to make sure they have not been damaged.
5HSDLU DQG 0DLQWHQDQFH &KDQJLQJ &KDQQHOV Savi RF Relays have been factory configured for operation; no settings or adjustments are required. However, it may become necessary to change the transmit and receive channels because of other equipment within the same area operating at the same frequency. The RF Modem inside the RF Relay can be set to transmit and receive at any one of 240 frequencies (channels). Frequency codes 10–250 are assigned to these channels.
