Note: The TX and RX signal levels are between 0.0 Volts and 3.3 Volts.
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.
USB 2.0 compliant Full Speed 12Mbps maximum speed. Hardware or Xon/Xoff handshaking supported; 300bps to 1Mbps. UART supports 5-8 bit data, 1-2 Stop bits, odd/even and no parity. Integrated EEPROM for Vendor ID, product ID, serial number, release number. Virtual COM port drivers allow operation with existing COM port PC applications. Supports Windows, MAC (OSX-9 and above) and Linux (2.4 kernel and above). USB powered; -40 to +85 deg C temp range. Small size; circuitry built inside the USB connector. 1.8m in length RoHS compliant.
Typical Applications: The 4D Programming Cable makes an easy USB to Serial interface, so you can easily create;
Interface micro-controller UART to USB USB to RS-232 converters USB to RS-422/RS-485 converters Upgrade legacy RS232 devices Make PDA and cellphone USB interface cables Serial Interface for barcode readers, POS terminals, etc.
The cable is designed specifically to interface directly with all 4D devices that use a 5pin programming header. In any non 4D device application, make sure the TX and RX lines from the cable are crossed over to the attached peripheral, that is, the TX from the cable connects to the RX of the target and the RX from the cable connects to the TX of the target device.
