MDS NX915 Integrator’s Guide Part No. 05-6697A01 1.0 INTRODUCTION The MDS NX915 (Figure 1), is a multi-modem modular system offering both Frequency Hopping Spread Spectrum and DTS transceiver modes that are designed for use in the license-free 902-928 MHz band. The unit is designed for use inside data equipment to provide reliable connectivity in wireless networks. The NX915 power control circuit ensures that the RF output never exceeds +30 dBm at the antenna connector. The module is designed for OEM use only. Host systems, if used with antennas having standard connectors, must be professionally installed. Host systems using integrated antennas or unique antenna connectors must be factory configured by the OEM to operate at the correct output power setting. Refer to the table at the end of this guide to determine applicable antenna types and the RF output power allowed. 1.1 Transceiver Features The NX915 maximizes performance and flexibility in wireless networks, offering the following key features: •Up to 81 channels over 902–928 MHz, divided into multiple zones •User-selectable option to skip sub-bands with interference •Multiple available network addresses •Network-wide configuration from the Master station, eliminating most trips to Remote sites •RSSI and LQI readback indicators •Poor load VSWR detection alarm indicator •Store-and-Forward repeater operation •Same hardware for Master, Remote, or Store-and-Forward configurations •Supports RS/EIA-232(TTL), Ethernet, and USB user interfaces •Operates at 4.5 Vdc at the MiniPCIe card edge power connections Figure 1. NX915 Transceiver Module (Mini PCI-Express Card Edge for Data/Power/& I/O and J300 Antenna) NOTE: Some features may not be available on all units, based on the options purchased, or regulatory constraints in the country of operation.
2.0 INSTALLATION The transceiver is designed for installation in existing electronic equipment. The I/O and power connections are made through the Mini PCI-Express card edge and it mounts to the host heatsink assembly using two #4 screws inside the RF can area. The required heatsink contact area on the bottom surface of the PCB has the solder mask removed for proper heat transfer. Only one cable connection is required to the radio for the J300 Antenna connector. Note that the module does have four optionally populated status LEDs (CR100, 101, 200, and 201) that indicate operating mode details. These LEDs provide important information that is useful during startup and optimization of the radio link. Antennas used with the radio can be either a Yagi directional type (often used at remote sites) or an omni-directional type used for short range applications or at Master stations. Contact your sales representative for information on available antennas. Follow these steps to install the transceiver module: 1. Power down the Host assembly the module is being installed in to. 2. Mate the MiniPCIe card edge of the module into the socket on the Host assembly. 3. Secure the module to the heatsink surface using two #4 screws through the mounting holes in the corners of the RF can area on the radio’s PC board. 3. Install the RF shield over the transceiver section. 4. Select and install an appropriate antenna and feedline for your system coverage requirements. 5. Connect the antenna coaxial lead to J300 on the module. It accepts a Type-TNC male coaxial connector. - For antenna gains higher than 6dBi, the system has been approved only with the following types: a. MDS PN: 97-3194A23 (Manuf. PN: Z2402 from PCTEL, Inc.), 7dBd (9.15 dBi), Omnidirectional b. MDS PN: 97-3194A14E (Manuf. PN: Z2342 from PCTEL, Inc.), 10dBd (12.15 dBi) Yagi 6. Host Power Supply Requirement: The input power applied to the unit must be 4.5 Vdc (-/+0.05 V). See Table 1 for power supply interface connections. Table 1. NX915 Power Supply Connections
