This model, USBCOM232-PLUS2, provides a simple method of adapting two legacy RS232 serial devices to a modern USB port. This is accomplished by incorporating the industry standard FTDI FT2232H USB2.0 Hi-Speed serial bridge chip. The integrated electronics of the USB-COM232-PLUS2 utilise the FTDI FT2232H plus two RS232 level shifters and TXD/RXD LEDs to provide a visual indication of data traffic through the module. Figure 1.1 USB-COM232-PLUS2 The module uses a standard USB-miniB 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. The USB-COM232-PLUS2 module requires USB device drivers, available free from www.ftdichip.com, which are used to make the USB-COM232-PLUS2 appear as two Virtual COM Port (VCP). This allows existing serial communications software, such as HyperTerminal, to exchange data through the USBCOM232-PLUS2 to a legacy RS232 peripheral device.

The maximum cable length is 5 meters, according to the USB 2.0 specification. FTDI FT2232H The FTDI FT2232H provides the USB-to-Serial conversion. Operating system device drivers are required in order to operate with the FT2232H to provide dual Virtual COM Port serial functionality. RS232 Level Shifter The RS232 level shifter converts the signals provided by the FT2232H into the voltage levels required by RS232 devices. DE-9P Connector (Male) The DE-9P connector is configured in an industry standard (TIA/EIA-574) pin-out to provide connection to RS232 peripherals through standard cables.

Insert the miniB-plug into the miniB-receptacle on the USB-COM232-PLUS2. RS232 cables have followed a standard 9-pin configuration on a D-sub connector since the mid 1980s. The USB-COM232-PLUS2 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 straightthrough cable can be used. DTE Pin Number Signal Name DCE Pin Number 1 DCD = Data Carrier Detect 1 2 RXD = Receive Data 2 3 TXD = Transmit Data 3 4 DTR = Data Terminal Ready 4 5 GND = RS232 signal ground 5 6 DSR = Data Set Ready 6 7 RTS = Request To Send 7 8 CTS = Clear To Send 8 9 RI – Ring Indicator 9 Table 2.1 – RS232 DTE to DCE connection with straight-through cable If the USB-COM232-PLUS2 is connected to another DTE device, a serial “null-modem” cable is required. A null-modem cable handles connecting output signals to the corresponding input signals on the other end. Table 2.2 shows a typical null-modem cable. Note that RI and DCD are not always used. DTE Pin Number Signal Name DTE Pin Number 2 RXD = Receive Data 3 3 TXD = Transmit Data 2 4 DTR = Data Terminal Ready 6 5 GND = RS232 signal ground 5 6 DSR = Data Set Ready 4 7 RTS = Request To Send 8 8 CTS = Clear To Send 7 Table 2.2 – RS232 DTE to DTE connection with null-modem cable Some serial devices may require certain handshake signals be connected. Refer to your device manual for cabling details.

This is the best choice when connecting the USB-COM232-PLUS2 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-PLUS2 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-PLUS2 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 Windows Update shown on Windows XP You must have an active Internet connection and the Windows Update Service enabled. 1) Connect the USB-COM232-PLUS2 to your USB Host or Hub. 2) The “Found New Hardware” Wizard will appear. The first dialog should ask whether it is acceptable to use the Windows Update Service to find the device driver. Figure 2.2 – Found New Hardware Wizard 3) Select one of the “Yes” choices and click “Next”. 4) The following screen appears: Copyright © 2010 Future Technology Devices International Limited 7 Document Reference No.: FT_000147 USB-COM232-PLUS2 Datasheet Version 1.1 Clearance No.: FTDI# 96 Figure 2.3 – Automatic Install 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. You must install the Virtual COM Port layer twice, because the USB-COM232PLUS2 has two Virtual COM Port. 8) When both portions of the device driver have been installed successfully, the following message will appear, indicating that the device is ready. Figure 2.5 - Hardware Ready COM Port Assignment Next, to determine which COM port has been assigned, open the Windows Device Manager from the System Control Panel.

You will see “USB Serial Port”, followed by a COMn assignment. In the figure below, the USB-COM232-PLUS2 is assigned to COM3 and COM4. Port A is always assigned the lower COM port number (COM3 in this example) and Port B the higher COM port number (COM4 in this example). Figure 2.7 - COM Port Assignment Use these COM port numbers with your application software in order to access the USB-COM232-PLUS2. If an application requires use of a different COM port number, the assignment may be changed through the Advanced Driver Options settings. From the Device Manager listing above, right-click on the USB Serial Port and select Properties. Figure 2.8 – Access COM Port Properties Next, click on the “Port Settings” tab.

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.
