  • Page 6: Introduction

    BIOS modifications you may require. This manual is fairly short. This is because for the most part, the TS-5300 is a standard x86-based PC compatible computer, and there are hundreds of books about writing software for the PC platform. The primary purpose of this manual is documenting where the TS-5300 differs from a standard PC.

  • Page 7: Power

    4.2 Flash There is a total of 1 or 2 MB of Flash memory on the TS-5300 with 128 KB reserved for the BIOS. During POST, this 128 KB area is copied from Flash into SDRAM at addresses E0000h through FFFFFh for improved performance (a standard technique known as BIOS Shadowing).

  • Page 8: Using The Sandisk Usb Compact Flash Card Reader

    Compact Flash reader/writer (which is included in the TS-5300 Developer’s Kit) is recommended for the host PC for file transfers. This results in the ability to quickly move files from a host PC to the TS-5300 using a Compact Flash card as the removable media. Since the Compact Flash card appears as a standard IDE drive on the TS-5300, it uses no additional RAM for drivers.

  • Page 9: Serial Port Configuration Registers

    Because both serial ports are 100% PC compatible, software written for the PC that accesses serial ports directly or through standard BIOS calls will work without modification on the TS-5300. The details of the COM port internal registers are available in most PC documentation books or the data sheet for the National Semiconductor NS16C550 may be consulted.

  • Page 10: Automatic Rs-485 Tx Enable

    The TS-5300 PC/104 bus has IRQ 5, 6, 7 or 9 available for additional serial ports. Typically each serial port has a dedicated interrupt, but the TS-SER4 allows all four extra serial ports to share a single interrupt.

  • Page 11: Digital I/O

    DIO2_3 have 4.7KΩ pull-up resistors biasing these signals to a logic”1”. DIO2_8 can be programmed to indicate the state of the TS-5300 LED. When bit 0 of I/O location Hex 79 is set, DIO2_8 will be a logic “1” when the LED is on. Setting bit 0 of I/O location Hex 79, forces DIO2_8 to be an output regardless of the state of bit 5 at I/O location Hex 7D.

  • Page 12: Using Lcd Port As Digital I/O

    IRQ1. 7 LCD Interface A 14-pin LCD connector is provided on the TS-5300 for interfacing with standard alphanumeric LCD displays. These displays use a common controller, the Hitachi HD44780 or equivalent. While software written for the HD44780 will work with all displays using the controller, the cable needed is dependent on the display used.

  • Page 13: Matrix Keypad Support

    This is useful if one wishes to use console redirection or to use a keyboard as stdin. See section 16 for an explanation of console I/O and redirection. See the Technologic Systems download page for example code.

  • Page 14: The 10 Base-T Ethernet Port

    The physical interface is 10Base-T (RJ45 connector). The TS-5300 has both a LINK LED and a LAN LED built into the RJ-45 connector that indicates the current ethernet status. The LINK LED (right side of connector) is active when valid ethernet link pulses are detected.

If the Technologic Systems kernel is used, the CS8900 driver is built into the kernel. The settings stored in EPROM on the TS-5300 are used to configure the CS8900.

    TS-5300 User’s Manual Technologic Systems 10 Real Time Clock The Dallas Semiconductor DS12887 is used for the PC compatible battery-backed real-time clock. It is a completely self-contained module that includes a Motorola 146818 compatible clock chip, the 32.768 kHz crystal, the lithium battery, and 114 bytes of battery-backed CMOS RAM. It is guaranteed to maintain clock operation for a minimum of 10 years in the absence of power.

We have found this allows the support of the IRQ5 vast majority of PC/104 boards including all of the above mentioned examples.

  • Page 22: Loading Or Transferring Files

    The TS-9500 daughter board provides full VGA video, keyboard, and mouse interfaces necessary to work within most environments. It also has a Compact Flash card that can be used even if the TS-5300 is using a Compact Flash card as well. You can transfer your development tools (e.g. Turbo C) onto the TS-9500 Compact Flash card.

  • Page 23: Debugging

    TS-5300 User’s Manual Technologic Systems 15 Debugging There are two main methods for debugging on the TS-5300: using the integrated BIOS debugger (INT3) and/or using your development tool's debugger (this usually requires the TS-9500 video and keyboard). 15.1 Integrated BIOS Debugger To provide simple, direct access to the TS-5300 hardware, the system BIOS has an integrated debugger that can perform standard low-level debugger functions.
