Introduction
1.1
Functional Description
The USB-RS232 adaptor cables are a family of communication devices. This model, ES-U-1001-C10
(C100), provides a simple method of adapting legacy serial devices with RS232 interfaces to modern USB
ports.
Each ES-U-1001-C10 (C100) adapter contains a small internal electronic circuit board which utilises the
FTDI FT232BL. The integrated electronics also include RS232 level shifters and TXD/RXD LEDs to provide
a visual indication of data traffic through the adapter.

Figure 1-2 ES-U-1001-C100
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-C10 (C100) adapter cable requires USB device drivers, available free from
EasySync
website,
which are used to make the ES-U-1001-C10 (C100) appear as a Virtual COM Port (VCP). This
allows existing serial communications software, such as HyperTerminal, to exchange data through the
ES-U-1001-C10 (C100) to a legacy RS232 peripheral device.
