1 Introduction
1.1 Functional Description
The USB-COM-Plus modules are a family of communication devices. This model, USB-COM232-Plus1,
provides a simple method of adapting legacy serial devices with RS232 interfaces to modern USB ports.
This is accomplished by incorporating the industry standard FTDI FT232R USB-Serial bridge chip.
The integrated electronics of the USB-COM232-PLUS1 utilise the FTDI FT232R and includes RS232 level
shifters plus TXD/RXD LEDs to provide a visual indication of data traffic through the module.
Figure 1.1 USB-COM232-Plus1
The module uses a standard USB-B device connector for connection to an upstream host or hub port.
RS232-level signals, including modem handshake signals, are available on an industry-standard DE-9P
connector. The maximum RS232-level data rate is 1Mbps.
Pin 9 of the DE-9P connector can be configured to output (+5V) with a configuration utility available free
from www.ftdichip.com.
The USB-COM232-Plus1 module requires USB device drivers, available free from www.ftdichip.com, which
are used to make the USB-COM232-Plus1 appear as a Virtual COM Port (VCP). This allows existing serial
communications software, such as HyperTerminal, to exchange data through the USB-COM232-Plus1 to a
legacy RS232 peripheral device.

2 Installation
2.1 Example Applications and Configurations
2.1.1 Wiring
Insert the A-plug into an available USB Host or Hub port. Insert the B-plug into the B-receptacle on the
USB-COM232-Plus1.
RS232 cables have followed a standard 9-pin configuration on a D-sub connector since the mid 1980s.
The USB-COM232-Plus1 follows this standard as a Data Terminal Equipment (DTE) device. If the RS232
equipment being connected is a Data Communication Equipment (DCE) device, it’s typical that a straight-
through cable can be used.
Signal Name
DCD = Data Carrier Detect
RXD = Receive Data
TXD = Transmit Data
DTR = Data Terminal Ready
GND = RS232 signal ground
DSR = Data Set Ready
RTS = Request To Send
CTS = Clear To Send
RI Ring Indicator / +5VDC
Table 2.1 RS232 DTE to DCE connection with straight-through cable
If the USB-COM232-Plus1 is connected to another DTE device, a serial “null-modem” cable is required. A
null-modem handles connecting output signals to the corresponding input signals on the other end.
Table 2.3 shows a typical null-modem cable. Note that RI and DCD are not always used.

2.2 Device Driver Installation
The USB-COM232-Plus1 module drivers are available for download from:
www.ftdichip.com
2.2.1 Microsoft Windows
With the device drivers being Windows Hardware Quality Labs (WHQL) certified, they are also available
through download directly from the Microsoft® Windows® Update service. This is the best choice when
connecting the USB-COM232-Plus1 to a computer running Windows Vista. Additional installation options
are noted below:
Installation Executable shown on Windows XP
1) Login to your system as Administrator, or a user with Administrator rights.
2) Prior to connecting the USB-COM232-Plus1 to the USB Host or Hub port, download the latest
device driver version from the FTDIChip web site.
3) Run this executable to install the device drivers.
4) Connect the USB-COM232-Plus1 to your computer. A notification will appear near the task bar
indicating that new hardware has been installed and is ready for use. It is normal if this notice
appears twice.
Figure 2.1 - Hardware Ready

5) Wait while the driver is found, downloaded, and installed. This step may take a couple minutes
depending on the Internet speed.
6) After the files are found and installed, click “Finish” to complete the installation.
Figure 2.4 - Complete Hardware Installation
7) Steps 2 through 6 will repeat. The first time installs the basic USB Serial Converter in the USB
device tree. The second time installs the Virtual COM Port layer in the Ports tree and assigns the
COM port number.
8) When both portions of the device driver have been installed successfully, the following message
will appear, indicating that the device is ready.

IEC60601
The USB-COM232-Plus1 has been tested to be compliant with IEC60601-1-2: Medical electrical
equipment - Part 1: General requirements for safety 2, Collateral standard: Electromagnetic
compatibility.
NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device,
pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against
harmful interference in a residential installation. This equipment generates, uses and can radiate radio
frequency energy and, if not installed and used in accordance with the instructions, may cause harmful
interference to radio communications. However, there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful interference to radio or television reception,
which can be determined by turning the equipment off and on, the user is encouraged to try to correct
the interference by one or more of the following measures:
Reorient or relocate the receiving antenna.
Increase the separation between the equipment and receiver.
Connect the equipment into an outlet on a circuit different from that to which the receiver is
connected.
Consult the dealer or an experienced radio/TV technician for help.
7.2 Safety
The USB-COM232-Plus1 is defined as Limited Power Supply (LPS) device, with operating voltages under
60VDC.
7.3 Environmental
The USB-COM232-Plus1 is a lead-free device that complies with the following environmental directives:
RoHS, WEEE, REACH, PFOS and DecaBDE.
7.4 Reliability
The USB-COM232-Plus1 is designed as a robust USB-Serial module for use in many environments. There
are no user-serviceable parts. Any failure will require a replacement of the unit.
7.4.1 MTTF
The Mean Time To Failure is calculated at TBD hours.

8 Troubleshooting
8.1 Hardware
Cables are the most common sources of trouble with external devices.
Check the following:
- USB cable is properly inserted at both ends
- Computer power is ON
- Computer is not in Sleep or Standby
- If a USB Hub is used, be sure it is set for “Self-Powered” operation
- If a USB Hub is used, be sure all cables are properly inserted
- If all the above are OK, the Yellow LED should be lit, indicating the device has been recognized by the
USB subsystem.
RS232 cables check the following:
- Output signals (TXD, RTS, DTR) are connected to the respective inputs (RXD, CTS, DSR) in each
direction.
- Check for specific handshake requirements of your RS232 peripheral.
- If handshake signals are note used, ensure the application is set to “No Hardware Handshake”, or
equivalent.
- Test the port with a loop-back connector. Connect TXD to RXD, RTS to CTS and DTR to DSR. Use a
simple terminal program to check that data is transmitted and received.
8.2 Device Driver
Ensure the latest device driver is in use. See www.ftdichip.com
If other devices with FTDI chips are installed in the system, check with all manufacturers of these devices
for the latest device drivers.
See the FTDI installation guides for additional details: http://ftdichip.com/Documents/InstallGuides.htm
Common Windows Device Driver Troubles:
DEVICE TIMES OUT: The default settings of the device driver assume typical data transfers of
hundreds to thousands or more bytes at a given time. Some applications, such as a GPS device,
only send data in short packets, often only a few bytes. If this is the case, it may be necessary
to adjust the driver buffer size and/or latency timer to smaller values. These values can be
adjusted through the Advanced driver options as noted in Figure 2.13. The buffer size can be
reduced to 64 bytes. The latency timer can be set as low as 2ms. A setting of 1ms will cause
unnecessary USB traffic and could adversely affect data transmission.
ERRATIC MOUSE POINTER: The device driver defaults to query an attached device to find out
whether it is a mouse or modem, consistent with native COM port operation. Some RS232
peripherals constantly send short packets of data, causing the host system to “think” a mouse or
modem has been attached. These short packets will interfere with normal mouse operation
causing the pointer to jump around the screen. If this happens, disconnect the RS232 device and
uncheck the Serial Enumerator option, also found on the Advanced driver options screen in Figure
2.13.
COM PORT IN USE: Windows keeps track of all COM port assignments. If multiple FTDIChip
products have been connected to a single system, the COM port number will increase, even if the
other devices are not attached. If the higher COM port assignments are not acceptable for the
application, known unused COM port numbers should be uninstalled according to the FTDI
installation guide: http://ftdichip.com/Documents/InstallGuides.htm.
