The model TS-3400 is a compact, full-featured PC compatible Single Board Computer based on the 386EX processor. If you are coming up from the 8-bit micro controller world, you will find that this product provides much more performance and much quicker development since you can now use standard PC development tools such as Turbo C or Quick Basic. If you have done work in the PC world in the past, you will find you can now build applications for a very small target that does not require a keyboard, video, floppy disks, or hard drives.
You can typically write and debug code on a host PC using standard development tools for the PC platform, then simply copy it to and run it on the TS-3400 without modification. If additional peripherals are required, the PC/104 expansion bus allows for many standard functions available off-the-shelf. It is also very simple to create a custom PC/104 daughter board for those special features that differentiate your product. Technologic Systems can provide technical support as well as a free quotation for any custom hardware, software, or BIOS modifications you may require.
This manual is fairly short. This is because for the most part, the TS-3400 is a standard 80386-based PC compatible computer, and there are hundreds of books about writing software for the PC platform. This is also in part because the TS-3400 is patterned from the TS-3200. The purpose of this manual is documenting where the TS-3400 differs from the TS-3200.
2 Differences Between TS-3400 and TS-3200
The TS-3400 is almost identical to the TS-3200. The TS-3400 was designed to be an extremely lowcost PC/104 board where the full horsepower of a TS-3200 is not needed. Therefore, the manual for the TS-3200 can be used except for the categories below detailing where they differ. A copy of the TS- 3200 can be found on our web-page for the TS-3200, or on the utility diskette of the TS-3400.
The TS-3400 uses an Intel 386EX chip running at 33 MHz clock rate.
2.2 Spread Spectrum Clock
The TS-3400 takes advantage of a spread spectrum clock to reduce the amount Electromagnetic Interference emitted by the TS-3400. The clock uses a spectrum spread modulated clock that modulates the clock driving the entire board. By eliminating a significant portion of EMI at its source (the clock) the SBC relies less on heavily expensive shielding, packaging, or extra components (such as ferrite beads) to reduce the amount of EMI by other circuits on the board. This will typically realize 15 to 10 db reduction in 100 MHz and higher ranges.
2.3 External Reset on DIO 2 header
Pin 10 of DIO 2 can be optionally set at manufacture time to be an active low reset. Pulling it low through an external filter for more than 1 millisecond will cause a complete reset of the board, effectively causing a "hard" reset of the machine. A resister pull-up keeps the pin in a de-asserted state.
2.4 Size Differences
The TS-3400 is slightly smaller than the TS-3200. It is PC/104 compatible, though it does take advantage of some reserved space of the PC/104 specification for right-angle connectors hanging at the edge of the board.
Though the COM ports are similar mechanically to the TS-3200, they are placed at the top of the board (versus at the left-hand side, like the TS-3200) in order to reduce the total size of the TS-3400. The LCD, DIO1, DIO2 ports are mechanically and physically-located the same as the TS-3200.
3 Product Notes
3.1 FCC Advisory
This equipment generates, uses, and can radiate radio frequency energy and if not installed and used properly (that is, in strict accordance with the manufacturer's instructions), may cause interference to radio and television reception. It has been type tested and found to comply with the limits for a Class A digital device in accordance with the specifications in Part 15 of FCC Rules, which are designed to provide reasonable protection against such interference when operated in a commercial environment. Operation of this equipment in a residential area is likely to cause interference, in which case the owner will be required to correct the interference at his own expense.
If this equipment does cause interference, which can be determined by turning the unit on and off, the user is encouraged to try the following measures to correct the interference:
Reorient the receiving antenna. Relocate the unit with respect to the receiver. Plug the unit into a different outlet so that the unit and receiver are on different branch circuits. Ensure that mounting screws and connector attachment screws are tightly secured. Ensure that good quality, shielded, and grounded cables are used for all data communications. If necessary, the user should consult the dealer or an experienced radio/television technician for additional suggestions. The following booklets prepared by the Federal Communications Commission (FCC) may also prove helpful:
How to Identify and Resolve Radio-TV Interference Problems (Stock No. 004-000-000345-4) Interface Handbook (Stock No. 004-000-004505-7) These booklets may be purchased from the Superintendent of Documents, U.S. Government Printing Office, Washington, DC 20402.
