TStik is powered by Dallas Semiconductor TINI


TStik Socket Compatibility Testing

TStik uses some pins used for power and ground on the TINI 390 module for other purposes. As a result, some customers using non-Systronix socket boards have had issues supplying power to TStik. These issues are generally solved by wiring Simm72 pins together.

Third party and Dallas socket boards

There are a number of Tini socket boards, designed for the Tini 390 already on the market. To evaluate a board not listed here, see the TStik.72.nb signal description: http://www.systronix.com/tinistik/signal_description.html you must connect pins (3 and/or 6 and/or 7), 9, and (68 and/or 69) for TStik.72.nb to work.

  • Vinculum protoAdapter
    • Pins 3, 6 and 7 are not connected to ground. Contrary to the TINI protoAdapter Header pin out we received with our test board, only pin 4 was connected to ground. This pin is used for serial4 on TStik and is not a ground pin on the TStik pin out Pin4 must be connected to pin 3, 6, and/or 7 for TStik to function.
    • Pins 68 and 69 are not connected to Vcc (+5V). Contrary to the TINI protoAdapter Header pin out, only pin 67 was connected to Vcc. This pin is not connected on TStik. Pin 67 must be connected to Pin 68 and/or 69 for TStik to work.
    • Also note that pin9, internal one wire VPP must be connected to either +5V, using the Vpp jumper on the protoAdapter, or +12V for programming. TStik uses a DS2502 to store its mac address and does not boot up properly without power to the internal one wire network.
  • Dallas DSTINIs400
    • This is not a SIMM72 socket board and will not work with TStik. The edge connector is a DIMM144 socket and is not compatible with TStik's SIMM72 form factor.
  • Legacy Dallas SIMM72 socket boards
    • TINI Socket Eurocard 72-pin Revision C: Make sure paste jumper J26 is installed, connecting Vcc to pin 9, Vpp.
    • TINI Socket Eurocard 72-pin Revision A: Make sure paste jumper J26 is installed, connecting Vcc to pin 9, Vpp.
    • Socket Plus is a 68 pin socket board. This board and other 68 pin socket boards listed on the socket boards web page will not fit a TStik.
  • Minimal socket board for TStik
    • This is not an actual product, just an example of what has to be connected to use TStik.
    • Ground must be connected. Use pin3, pin 6, or pin 7.
    • Vcc must be connected. Connect +5V to pin 68 or pin 69.
    • Pin 9, VPP must be connected to +5V for normal operation.
    • Pin 19 is TX232, the serial0 transmit pin. This should be connected to the receive pin of your PC serial port for programming purposes with Javakit.
    • Pin 20 is RX232, the serial0 transmit pin. This should be connected to the transmit pin of your PC serial port for programming purposes with Javakit.
    • Pin 25 is DTR232, it is used for resetting TStik in Javakit to access the serial loader.
