RN-134 & RN-174 Hardware Setup
To set up the RN-134 and RN-174 evaluation kit hardware, perform the following steps:
1.
Provide power to the board by soldering the provided 9-battery clip wire to the board (J7) and attaching a 9-V battery
to the clip.
2.
Connect the 10-pin serial cable to the evaluation board (J3). When looking at the top of the board, the cable should
extend away from the board.
NOTE:
If your computer has a DB9 connector, you can connect the 10-pin serial cable directly to it to complete
setting up the hardware. The COM port in this case is COM1.
3.
Connect the USB-to-serial cable to a USB port on your computer. Windows should automatically install the drivers for
the cable. If it does not, download and install the Prolific drivers from the Support page on the Roving Networks
website at
http://www.rovingnetworks.com/support.php
. Note the COM port to which you have attached the cable.
4.
Connect the USB-to-serial cable to the 10-pin serial cable using the null modem.
Figure 12 shows the completed hardware setup for the RN-134 and RN-174 evaluation boards.
NOTE:
By default, the WiFly module uses either the on-board chip antenna (RN-131G-EVAL and RN-134) or the
PCB trace antenna (RN-174). If an antenna is included in your kit, you do not need to install it for the
evaluation described in this document.

Refer to Power (J5) Figure 10 (RN-134) and Power (J7) in Figure 11 (RN-174) for information on where to
solder the wires.
