Version 1.0

Issue Date: 2010-06-15

The USB2-H-9004-M provides a simple method of adapting legacy serial devices with RS232 and

RS485 interfaces to modern USB ports by incorporating the FTDI FT4232H Hi-Speed USB bridge chip.

The adaptor, which is contained within a metal case, can be externally powered and can supply an

output of +5VDC @ up to 250mA on the 5mm terminal block connectors. Indicator LEDs provide

functional status.

Introduction

1.1

Functional Description

The USB2-H-9004-M adaptor is a USB to quad interface RS232 or RS485 level serial UART adaptor

incorporating FTDI’s FT4232H Hi-Speed USB2.0 (480Mb/s) to quad serial UART interface IC device. The

FT4232H handles all the USB signaling and protocols. The adaptor is housed in a metal enclosure and

provides a fast, simple way to connect devices with an RS232 or RS485 interface to USB.

The integrated electronics of the USB2-H-9004-M utilise the FTDI FT4232H and includes RS485 level

shifters and RS232 level shifters plus TXD/RXD LEDs to provide a visual indication of data traffic through

the adapter. Selection of RS232 or RS485 signalling is made using DIL switches on the front of the

adaptor. Each of the quad channels can be independently configured as either RS232 or RS485.

Figure 1.1 USB2-H-9004-M

Flexible mounting allows the USB2-H-9004-M 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 metal enclosure incorporates a standard USB-B client connector for connection to an upstream host

or hub port. RS232 and RS485-level signals are available on four 5mm terminal block connectors. The

maximum RS485-level data rate is 10Mbps and the maximum RS232-level data rate is 1Mbps.

The adapter can be independently powered using an external +5V DC (1A) power supply which connects

via a 2.1mm jack socket. It can also be powered from the USB interface if required.

The USB2-H-9004-M adapter requires USB device drivers, available free from

http://www.easysync-

ltd.com.

These are used to make the USB2-H-9004-M appear as a Virtual COM Port (VCP). This allows

existing serial communications software, such as HyperTerminal, to exchange data through the USB2-H-

9004-M to a legacy RS485 or RS232 peripheral device.
