Default Addresses
The default 7-bit I
2
C address of DS90UB913AQ is set to 0x58 (101 1000) using suitable resistor divider on
ID[x] pin. Also, 7-bit I
2
C address of DS90UB914AQ is set to 0x60 (110 0000) using suitable resistor
dividers on pins IDx[0] and IDx[1]. Change resistor R25 on Serializer board and R32, R33 on Deserializer
board to change the address of these devices, refer device datasheet for more information.

USB2ANY
(1)
The USB2ANY is required to use interactive GUI over I
2
C, such as ALP (Analog LaunchPAD).
Download and install ALP from:
http://www.ti.com/tool/ALP
.
Before using ALP for these devices, it is also required to download DS90UB913-914-ALP-PROFILES from
the same web page and copy DS90UB913 and DS90UB914 folders to location:
Program Files\Texas
Instruments\Analog LaunchPAD vx.xx.xxxx\Profiles
on your system.
The USB2ANY is shown in
below. It is powered through the USB port of computer and LED D1
will light up GREEN when the USB2ANY is connected to a computer to indicate that the board is powered.
