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.
