Kb/s data throughput. Applicable hardware This manual covers both the 9XTend-PKG-U USB RF Modem and the XTend vB USB RF Modem. Throughout the manual, you will see references to the Legacy Modem and the XTend vB Modem. Legacy modems have part numbers with the format XT09-PK.-.and contain radio model XT09.
FCC Approved (USA) Refer to Agency certifications on page 73 for FCC Requirements. Systems that include XTend RF Modems inherit Digi’s Certifications. ISM (Industrial, Scientific and Medical) license-free 902-928 MHz frequency band Manufactured under ISO 9001:2000 registered standards 9XTend RF Modems are optimized for use in the US, Canada, Australia and Israel Specifications Out-of-box, the 9XTend RF Modem is configured to provide immediate long range wireless links between devices.
This document describes how Digi RF products are designed to have good out-of-band interference rejection from other sources of RF emissions 1 MHz or more away from the frequency in which the Digi RF product is designed to operate. An out-of-band interfering radio is one that is intended to broadcast in one frequency but has RF energy that bleeds-over to affect a second radio operating on a different frequency.

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 Digi 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;...
XTend RF Modems operate in five modes. Idle mode When not receiving or transmitting data, the RF modem is in Idle Mode. The modem shifts into the other modes of operation under the following conditions: 9XTend-PKG-U USB RF Modem User Guide...
This could be the case if more than PK bytes were originally pending in the DI buffer or if more bytes arrived from the UART after the transmission began. If more data is pending, the transmitting modem assembles a subsequent packet for transmission. 9XTend-PKG-U USB RF Modem User Guide...
