1.2 General Description
All operational power for the DLP-TXRX-G is taken from the host PC USB port or
upstream hub. All power required by user electronics must be provided by external
power supply.
FTDI provides a royalty free Virtual COM Port (VCP) driver that makes this USB device
appear as a standard COM port to the PC. Most existing software applications should be
able interface with the Virtual COM Port simply by reconfiguring them to use the new
COM ports created by the driver. Using the VCP drivers, an application program would
communicate with the DLP-TXRX-G in exactly the same way as it would a regular
RS232 COM port - using the Windows VCOMM API calls or a COM port library.
Also available is a DLL version of the drivers that allows application programmers to
interface software directly to the device using a Windows DLL. Both the VCP and DLL
version of the drivers are available for download from both the dlpdesign.com and
ftdichip.com web sites.
The on-chip EEPROM can be used to customize the USB VID, PID, Serial Number,
Product Description Strings and Power Descriptor value of the DLP-RXTX-G for OEM
applications. The EEPROM is programmable in-circuit via USB using a utility program
(MPROG) available from both www.ftdichip.com and www.dlpdesign.com.
