1Introduction
1.1 Functional Description
The USB-RS232 adaptor cables are a family of communication devices. This model, ES-U-1001, provides
a simple method of adapting legacy serial devices with RS232 interfaces to modern USB ports.
Each ES-U-1001-R10 adapter contains a small internal electronic circuit board which utilises the FTDI
FT232R, mounted inside a rugged plastic enclosure capable of withstanding industrial temperature
ranges. The integrated electronics also include RS232 level shifters and TXD/RXD LEDs to provide a
visual indication of data traffic through the adapter.
Flexible mounting allows the ES-U-1001-R10 to be used in a variety of applications, from a portable
adapter to accompany a laptop to permanent installations in industrial, commercial and retail locations.
The Cable incorporates a standard USB-A 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 1MBaud.
The ES-U-1001-R10 adapter cable requires USB device drivers, available free from the Connective
Peripherals website, which are used to make the ES-U-1001-R10 appear as a Virtual COM Port (VCP).
This allows existing serial communications software, such as HyperTerminal, to exchange data through
the ES-U-1001-R10 to a legacy RS232 peripheral device.
1.2 Typical Applications

2FT232R Key features
This section summarises the key features and enhancements of the FT232R IC device which is used
on the ES-U-1001-R10 USB to RS232 converter cable. For further details, consult the FT232R
datasheet, which is available from the FTDI website.
2.1 Integrated EEPROM
Previous generations of FTDI’s USB UART devices required an external EEPROM if the device were to
use USB Vendor ID (VID), Product ID (PID), serial number and product description strings other
than the default values in the device itself. This external EEPROM has now been integrated onto the
FT232R chip meaning that all designs have the option to change the product description strings. A
user area of the internal EEPROM is available for storing additional data. The internal EEPROM is
programmable in circuit, over USB without any additional voltage requirement.
2.2 Pre-programmed EEPROM
The FT232R is supplied with its internal EEPROM pre-programmed with a serial number
which is unique to each individual device. This, in most cases, will remove the need to program the
device EEPROM.
2.3 Lower Operating and Suspend Current
The device operating supply current has been further reduced to 15mA, and the suspend current
has been reduced to around 70μA. This allows greater margin for peripheral designs to meet the
USB suspend current limit of 500μA.
2.4 Low USB Bandwidth Consumption
The operation of the USB interface to the FT232R has been designed to use as little as possible of
the total USB bandwidth available from the USB host controller.
2.5 UART Pin Signal Inversion
The sense of each of the eight UART signals can be individually inverted by setting options in the
internal EEPROM. Thus, CTS# (active low) can be changed to CTS (active high), or TXD can be
changed to TXD#.
2.6 FTDIChip-ID™
Each FT232R is assigned a unique number which is burnt into the device at manufacture. This ID
number cannot be reprogrammed by product manufacturers or end-users. This allows the possibility
of using FT232R based dongles for software licensing. Further to this, a renewable license scheme
can be implemented based on the FTDIChip-ID™ number when encrypted with other information.
This encrypted number can be stored in the user area of the FT232R internal EEPROM, and can be
decrypted, then compared with the protected FTDIChip-ID™ to verify that a license is valid. Web
based applications can be used to maintain product licensing this way. An application note
describing this feature is available separately from the FTDI website.
2.7 Improved EMI Performance
The reduced operating current and improved on-chip VCC decoupling significantly improves the ease
of PCB design requirements in order to meet FCC, CE and other EMI related specifications.

Version 1.1
Document Reference No.: CP_000057 Clearance No.: CP#047

2.8 Programmable Receive Buffer Timeout
The receive buffer timeout is used to flush remaining data from the receive buffer. This time
defaults to 16ms, but is programmable over USB in 1ms increments from 1ms to 255ms, thus
allowing the device to be optimised for protocols that require fast response times from short data
packets.
2.9 Baud Rates
The FT232R supports all standard baud rates and non-standard baud rates from 300 Baud up to 3
Mbaud. Achievable non-standard baud rates are calculated as follows -
Baud Rate = 3000000 / (n + x)
Where n can be any integer between 2 and 16,384 (= 214) and x can be a sub-integer of the value
0, 0.125, 0.25, 0.375, 0.5, 0.625, 0.75, or 0.875. When n = 1, x = 0, i.e. baud rate divisors with
values between 1 and 2 are not possible.
This gives achievable baud rates in the range 183.1 baud to 3,000,000 baud. When a non-standard
baud rate is required simply pass the required baud rate value to the driver as normal, and the FTDI
driver will calculate the required divisor, and set the baud rate. See application note AN232B-05 for
more details.
The ES-U-1001-R10 cable is limited to a maximum of 1 Mbaud because of the line driver within the
circuit.

3.2 Device Driver Installation
The ES-U-1001-R10 adaptor drivers are available for download from:
https://www.connectiveperipherals.com
3.2.1 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 ES-U-1001-R10 to a computer running Windows Vista. Additional installation options are
noted below:
Installation Executable on Windows XP
1) Login to your system as Administrator, or a user with Administrator rights.
2) Prior to connecting the ES-U-1001-R10 to the USB Host or Hub port, download the latest device
driver version from the Connective Peripherals web site.
3) Run this executable to install the device drivers.
4) Connect the ES-U-1001-R10 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.
