  • Page 6: Introduction

    BIOS modifications you may require. This manual is fairly short. This is because for the most part, the TS-5500 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-5500 differs from a standard PC.

  • Page 7: Power

    4.2 Flash There is a total of 2 MB of Flash memory on the TS-5500 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

    Technologic Systems host PC for file transfers. This results in the ability to quickly move files from a host PC to the TS-5500 using a Compact Flash card as the removable media. Since the Compact Flash card appears as a standard IDE drive on the TS-5500, it uses no additional RAM for drivers.

  • Page 9: Serial Port Configuration Registers

    This is quite sufficient to interface with the vast majority of serial devices. If additional handshake lines are required, it will be necessary to add a TS-SER daughter board. The TS-5500 serial signals are routed to 10-pin header labeled COM1 and a standard 9-pin Sub-D male labeled COM2 and COM3. A serial adapter cable can be plugged into the COM1 header to convert this into a standard DB9 male connector.

    DOS. The TS-5500 PC/104 bus has IRQ 5, 6, 7, 12 or 15 available for additional serial ports. Note: IRQ7 is used by many PCMCIA cards and COM3 will typically use IRQ5 or IRQ6.

  • Page 11: Digital I/O

    IRQ lines available. 6 Digital I/O There are 38 Digital Input/Output (DIO) lines available on the TS-5500. These are available on 3 headers labeled DIO1, DIO2, and LCD. In addition to the DIO signals, each header also has 5 Volt power and Ground available, while the DIO2 header has an external reset available on pin 12..

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

    The digital inputs have standard TTL level thresholds and must not be driven below 0 Volts or above 5.0 Volts. DIO lines DIO1_0 thru DIO1_7 have 4.7KΩ pull-up resistors to 5V biasing these signals to a logic”1”. 7 A/D Converter The TS-5500 supports an optional eight-channel, I/O Address Action 12-bit A/D converter (ADC) capable of 60,000 samples per second.
