evaluation kit includes a 5V wall adapter with a USB plug to allow powering the evaluation
The
board from a standard power strip. The evaluation board includes all the necessary regulators
to power the PremierWave 2050 module and contains the following features:
♦ Two DB9 serial port connectors with multi-protocol RS232, RS422, RS485 transceivers
at rates up to 1 Mbps. Serial port modes are configured by on-board jumpers.
♦ One RJ45 10/100 Ethernet port with an integrated PoE regulator to allow powering from
a standard POE PSE.
♦ One mini-type B USB device port connector for 5V input power. This port also has an
integrated USB-to-serial converter. The USB-to-serial converter is connected to the
PremierWave 2050 module serial debug port.
♦ A second mini-type B USB device port is available for connection to the PremierWave
2050 module USB 2.0 high speed device port.
♦ Two USB host ports are available on a dual USB type A connector. One of the ports is
USB 2.0 high speed and the second is USB 2.0 full speed.
♦ LEDs are available for the Ethernet, WLAN, and system status outputs. The Ethernet
LEDs are integrated with the RJ45 Jack.
♦ Access to all logic level IO signals on the PremierWave 2050 via header pins for
Standard DB9 port for connection to RS232, RS485, and RS422 networks

The PremierWave 2050 evaluation board includes two brackets for mounting the U.FL to
reverse polarity SMA RF cables included with the kit. Follow the procedure below when
installing the antenna cable. The same procedure applies when using the PCB strip antenna,
with the exception that the swivel antenna does not need to be connected to the RF cable.
1. Attach the U.FL cable to the antenna prior to installing the PremierWave 2050 module.
2. Install the external antenna to the SMA end of the RF cable.
Note: Install or remove the antenna connections only while the module is powered
