Chapter 3: Setting up the Interface and Test Board
36 RIM OEM Radio Modem for GSM/GPRS Wireless Networks
To connect the antenna to the radio modem
The Integrator Kit includes a high-performance, 3 dB-gain magmount antenna, which is terminated
by a screw-on SMA plug. The radio modem includes a snap-on MMCX jack.
1. Insert the antenna into the base and turn the antenna until the two components are securely
fastened.
2. Insert the SMA cable connector into the MMCX connector and turn the SMA connector until the
two components are fastened securely.
Connecting the SMA cable to the MMCX connector
3. Insert the MMCX connector into the radio modem’s MMCX jack.
4. Position the antenna for optimal coverage. The magmount antenna provides optimum RF
performance when it is placed on a broad metal surface, such as the roof of a car. If you are using
the antenna inside a building, for improved performance, place it near a window with few
obstacles (such as a wall, furniture, or equipment) between the antenna and the window.
To connect the Interface and Test Board to an AC outlet
Plug the 5V DC, 2.4A, center-pin-positive power adapter into an electrical outlet. Connect the other
end to the Interface and Test Board’s power jack.
To turn on the system
Move the power switch to the TURNON position to allow the radio modem to power up.
When the radio is on, the LED marked
ONI
is lit. Refer to "Turning on and turning off the radio" on
page 57 for more information.
To connect the headset
1. Insert the microphone plug into the microphone jack.
2. Insert the speaker plug into the speaker jack.
Note: If you connect the antenna before you connect the Interface and Test Board to an AC outlet, the radio
modem detects network coverage more reliably.
