Socket Boards
for TStik
TINI400 in the familiar
SIMM72 module

TStik is powered by Dallas Semiconductor TINI

TStik will operate in any properly designed current TINI390 socket board, so you don't need a special socket to use TStik. But to take advantage of the new TINI400 features, such as serial4, NetBoot and enhanced SPI, we are providing new socket boards which are optimized for TStik.

Production version TStik TILT400.Lite and TILT400.Pro photos and details. Both are now shipping.
This is the first TStik socket board to be released.
This is a specification for the simplest and lowest cost TStik socket board. It has a single vertical (vertical sockets are about 1/4 the price of right angle) SIMM72 socket. This simple socket enables use of TStik with wide-range power input, 10/100 BaseT ethernet, serial x 2, CAN and 1-Wire, and one JSimm expansion slot.
  1. Moderately priced, rugged, OEM board for TStik.72.nb. TINI390 will also work in this board.
  2. Physically small - 100 x 100 mm fits our SnapTrack and other standard Euroboard enclosures
  3. High volume OEM use
  4. other uses where you might need to add your own small board with an I2C or SPI device or two.
  5. Educational use. The JSimm slot can be used for I/O expansion via SPI, I2C and serial.
  6. JSimm slot can accomodate many JSimm/SimmStick cards such the new JXTA RF Modem
TILT400 photo

Here is a photo of TILT400.Pro. There is also a Lite version which is the same circuit board but partially populated. The Lite version is similar in function to our current TILT board for the TINI390. The Pro version offers expandability (similar to STEP) for TStik. (There will not be a STEP board for TStik.72.nb since it has no memory mapped I/O and cannot drive the SBX connector or an expansion SIMM72.)

Due to the Euroboard size it *is*compatible with our SnapTrack panel- and DIN-rail- mounting hardware.

Note the stacked DB9 connectors for Serial0 (DCE) and Serial4 (DTE).

The unconventional angle of the Simm sockets is necessary to provide enough clearance between them and the various connectors, and stay on a 100 x 100 mm board, with the edge keepouts required for Euroboard card cages and SnapTrack.

Simm72 socketOne vertical Simm72 socket for TStik or TINI390
Simm30 socket (Pro only)One vertical Simm30 JSimm expansion socket. There is no memory mapped I/O per se from TStik.72.nb so only the I2C, SPI, 1-Wire, and asynchronous serial lines are connected to the JSimm socket. Plus there is a SPI-based output register on the socket board which drives eight of the JSimm I/O lines as outputs. This allows for a lot of expansion options such as I2C or SPI ADC, DAC, motor controllers, LCD interface, 1-Wire, etc. And the TTL serial signals will enable use with our planned RFModem board, making this a wireless node with JXTA peer-to-peer support.
RS232 Serial0DB9 female as DCE with DTR enable jumper. Used by JavaKit, or as a general serial port. No hardware handshake signals. Same as STEP board's serial0.
Serial1 (1Wire RJ12)Dedicated to 1Wire via an RJ12 jack.
RS232 Serial4 (Pro only)DB9 male as DTE for RS232, with hardware handshake lines. This provides a full-featured RS232 port even with 1Wire active on serial1. No IrDA support (since there is no 16X IrDA clock available).
CAN header 5x2 (Pro only)CANOpen pinout 100-mil shrouded 5x2 header, same as STEP board and TILT.CAN. Uses standard adapter to CANOpen DB9, or you can just use ribbon cable for short distance (fifty feet or less) desktop CAN networks between multiple boards.
RJ45 ethernet 10/100 BaseTEthernet jack now supports 10 and 100 BaseT, with surge suppression and "Bob Jones" termination of unused lines
I2C Buffered (Pro only)The Philips 9515 repeater buffers the I2C lines from TStik to the JSimm connector
SPI with address expansion (Pro only)SPI plus three additional address bits for JCX SPI address expansion are provided on the JSimm connector. This supports up to 24 SPI chip select locations when used with the new JCX CPLD SPI address expander.
1-Wire RJ12 and iButton socketDallas 1-Wire is available on the RJ12 connector (with standard Dallas/Systronix pinout) and on the JSimm connector as well as the iButton clip. The RJ12 connector provides power both raw and 5 VDC. The iButton socket by default is on the external 1-Wire net but can be moved (with paste jumpers) to the internal 1-Wire net for use with SHA iButtons or other authentication or protection purposes. Since the internal 1Wire network is not as rugged as the external, you don't want to risk an ESD hit by planning to have users walk up to a system and plug iButtons repeatedly on the internal 1Wire net.
Header for Embedlet sensor net expansion (Pro only) Shrouded header provides easy plug-on access to SPI, I2C, 1Wire and power. Requested by the open-source Embedlet project and by educators for classroom use.
8 Digital Outputs (Pro only)A SPI shift register drives eight JSimm lines. Three may be used for SPI address expansion, leaving at least five for your use as general JSimm output bits. All eight can be used as outputs if you are not using SPI.
NetBoot support (Pro only)Support for a DS2430 or DS2433 Netboot device on the TStik internal 1-Wire net for the new TINI400 NetBoot options.
XML Tagging and ID support (Pro only) Support for a 1 kbit DS2430 or 4 kbit DS2433 Netboot device, with unused space available for node ID, XML device tagging, etc. These devices are on the TStik internal 1Wire bus which is isolated from the external 1Wire network.
Ethernet ESD protection and terminationTVS devices are used on the ethernet signals to provide surge suppression. The RJ45 also provides the "Bob Smith" termination of unused lines.
On-board "external" 1-Wire devices (Pro only)Serial1 is dedicated to 1Wire support on TStik.72.nb through the onboard DS2480B. On this "external" 1Wire network are a DS18S20 temperature sensor and an iButton clip. You can also attach an iButton device by plugging a Blue Dot reader into the 1Wire RJ12 jack.
Reset pushbuttonHas the same function as a DTR reset when pressed
Power supplyRugged switching regulator with 8-24 volts AC or DC input, 5.5x 2.5 mm power jack, same as STEP. Reverse polarity protected (since it accepts AC). Provides 5 VDC 1 Amp to the TINI sockets, JSimm, 1Wire network, etc.
