    The external power must supply a DC voltage between 5 and 12 V. The power supply currently shipped with MaxStream Development Kits is a suitable power supply for this option. XCite-PKG-U RF Modem automatically selects "self-powered mode" if power is available on the power connector when the RF modem is connected to USB.

  • Page 8: Rf Modem Operation

    USB has two types of devices: Those that supply drivers (a host, such as a PC); and those that require a driver (a client, such as a MaxStream USB RF Modem). When a USB client is plugged into a host, the host prompts for a driver. Once a driver is located, the host loads the driver on the first use of the USB client;...

  • Page 9: System Description

    The XCite-PKG-U USB RF Modem is most commonly used as an access point in a network of serial RF modems (such as MaxStream's RS-232/485 RF Modems). The XCite RF Modems support point- to-point, peer-to-peer, point-to-multipoint and multidrop network topologies. The section below illustrates a typical point-to-multipoint network application.

  • Page 10: Modes Of Operation

    After the channel is initialized, data in the DI buffer is grouped into packets (up to 64 bytes in each packet) and is transmitted. The modem continues to transmit data packets until the DI buffer is empty. Once transmission is finished, the modem returns to Idle Mode. This progression is shown below: Figure 2‐03. Transmission of data © 2007 MaxStream, Inc.      10...

  • Page 11: Receive Mode

    If serial data-to-transmit is stored in the DI buffer while the modem is giving precedence to Receive Mode, the data will be transmitted after the modem finishes receiving data and returns to Idle Mode. © 2007 MaxStream, Inc.      11...

  • Page 12: Sleep Modes

    When the modem awakens to listen for data, CTS is asserted and any data received on the DI Pin is transmitted. The PWR pin is also de-asserted (low) when the modem is in Cyclic Sleep Mode. These pins are asserted each time the modem cycles © 2007 MaxStream, Inc.      12...

    Only modems with matching VIDs can communicate with each other. VID addressing ensures that radio modems ignore transmissions and receptions of XCite Radio Modems having a different VID in the same vicinity. To request a unique VID, contact MaxStream to obtain the VID Request Form.

    Section 15.203 (unique antenna connectors) and Section 15.247 (emissions). Fixed Base Station and Mobile Applications MaxStream RF Modems are pre-FCC approved for use in fixed base station and mobile applica- tions. When the antenna is mounted at least 20cm (8") from nearby persons, the application is considered a mobile application.
