Preface
The USB-485M is a convenient USB-to-RS-485 converter, which does not require an external power
supply or a complex configuration process. It supports baud rates from 75 to 115.2 kbps, and auto
switching direction of data transmission. In addition, it accomplishes RS-485 data transmission
using RJ-45 connectors for convenient wiring. Its small size, handy use of plug-and-play, and hot-
swap capability also provide more convenience for users.
USB–485M includes:
• USB-to-RS–485 serial communication adapternext line.

Wiring connections
The wiring connector on the USB-485M is a standard 8-pin RJ45 receptacle.
A standard 6-pin RJ12 connection plug fits into the RJ45 receptacle,
but it connects only the middle six pins. RJ12 pins 1–6 connect to RJ45 pins 2–7.

PreParations before installing driver (extract the driver file)
Install the driver file onto your PC BEFORE installing the USB-485M communication adapter. The
driver file (USB-485M_Drivers.exe) is located on the mini-CD supplied with the USB-485M.
Do NOT connect the USB-485M to your PC before extracting the driver file.
Insert the mini-CD into your PC, follow the file installation prompts, and accept the default
selections except as shown below. (The following screen captures are from 32-bit Windows 7. The
installation windows from other operating systems may vary somewhat.)
• Select the file “USB-485M_Drivers” for installation:
• “Silicon Laboratories CP210x Evaluation Kit Tools” will be installed on your PC:

Preparations BEFORE Installing Driver (Extract the Driver File) (continued)
• Use the “Browse...” button only if you want to install the driver file in PC folder other than the default
folder (not recommended):
driver installation
Do NOT connect the USB-485M to your PC before extracting the driver file.
AFTER installing the driver file onto your PC, connect the USB-485M communication adapter to the
USB port of the PC and install the driver onto the USB-485M.
Follow the file installation prompts and accept the default selections except as shown below.
(The following screen captures are from Windows XP Service Pack 3. The installation windows from
other operating systems may vary somewhat.)
• We recommend “Install from a list...”, especially if you installed the driver file on your PC in a file
location other than the default location.
troUbleshooting
(Required Only if Driver Installation is Unsuccessful)
• With the USB-485M connected to the PC, go to:
Control Panel --> System --> System Properties --> Hardware --> Device Manager --> Other devices,
and select the “CP2103 USB to UART Bridge Controller”:
• From the “General” tab, select “Update Driver...”
• Browse to the file location where the driver is stored:
• After the driver is successfully updated, the applicable comm port will show in Device Manager.
(The comm port number may vary depending upon your PC.)
Double click the comm port to set the baud rate, stop bits, etc.
