The 4D Programming Cable is a USB to Serial-TTL UART converter cable. It incorporates
the Silabs CP2102 USB to Serial UART bridge IC which handles all the USB signalling
and protocols. The cable provides a fast and simple way to connect all of the 4D
devices that require TTL level serial interface to USB. The Programming Cable is
also an essential hardware tool used for programming PmmC files and 4DGL user code
downloads into the GOLDELOX, PICASO and DIABLO processors embedded in many 4D modules.
The cable contains a small internal electronic circuit board, utilising the CP2102
chip and special RESET circuitry, which is encapsulated into the USB connector at
the end of the cable. The cable is RoHS compliant and is available with a 5pin female
header (0.1”/2.54mm pitch) at TTL levels of 3.3V for RX and TX. The 5pin header
is labeled with the appropriate signal names: +5V, RX, TX, GND, RESET which match
the programming headers on the 4D devices. The cable also provides +5V DC supply
to power up the target device. The cable is 1.8m in length and the circuitry is
USB powered (USB 2.0 compliant full speed @ 12Mbps) and supports data rates from
300bps to 1Mbps.
