TTL234X SERIES RANGE OF CABLES

Description
The
TTL-234X
cables are a family of USB to TTL serial UART converter cables incorporating FTDI’s
FT234XD USB to basic UART interface IC device which handles all the USB signalling and protocols. The
cables provide a fast, simple way to connect devices with a TTL level serial interface to USB.
Each TTL-234X cable contains a small internal electronic circuit board, utilising the FT234XD, which is
encapsulated into the USB connector end of the cable. The FT234XD datasheet,
DS_FT234XD,
is available
at
http://www.ftdichip.com.
The other end of the cable comes with a selection of different connectors
supporting various applications – see Table 1.1
Cables are FCC, CE, RoHS compliant and are available at TTL levels of +5V and +3.3V.
Cables are available with either a 6-way SIL,0.1” pitch connector, a 3.5mm Audio Jack, an 8 way, keyed
2mm pitch connector (intended for use with VMUSIC2 or VDRIVE2), or bare, tinned wire ended
connections (see Table 1.1)
The USB side of the cable is USB powered and USB 2.0 full speed compatible. Each cable is 1.8m long
and supports a data transfer rate up to 3 Mbaud.
The TTL-234X cables require USB drivers, available free from
http://www.ftdichip.com,
which are used to
make the FT234XD in the cable appear as a virtual COM port (VCP). This then allows the user to
communicate with the USB interface via a standard PC serial emulation port (for example TTY). Another
FTDI USB driver, the D2XX driver, can also be used with application software to directly access the
FT234XD on the cable though a DLL. This is illustrated in the Figure 1.1
