    2 Hardware Configuration The DSC-100 is automatically configured at boot time by the computer's BIOS or operating system. There are no required switches or jumpers to set for installation. This chapter lists a number of optional jumper settings that control various hardware features. Jumpers J5-J8 are grouped together at the end of the board o ...

    2 . 3 Force High-Speed UART Clock (X2, X4, or X8, J 5 -J 7 ) These jumpers force an increase of the UART input clock frequency by a factor of two, four, or eight. This can allow legacy software to use baud rates above 115,200 bits per second. It is also useful if the serial port device driver does not directly support setting the higher baud rates ...

  • Quatech DSC-100 - page 10

    2 . 4 DTE/DCE Selection To simplify connections to other devices, each port on the DSC-100 is equipped with a jumper block that allows the port to be configured as either a DTE- or DCE-type device. This allows the DSC-100 to connect to either DTE- or DCE-type devices without using a null modem cable. The DTE/DCE selection jumper blocks are illustra ...

    4 . 2 Enabling the Special Registers The DSC-100 contains two unique registers, an Interrupt Status Register and an Options Register. These registers are enabled when the SPAD jumper (J 8 ) is removed (factory default). They replace the UART Scratchpad Register on accesses to register address 7. The Interrupt Status Register and Options Register ar ...

    4 . 4 Options Register The Options Register allows software to identify the DSC-100 as a Quatech Enhanced Serial Adapter. It also allows software to set the UART clock rate multiplier. Figure 10 shows the structure of the Options Register. The powerup default of the Options Register is all bits zero. Clock rate multiplier bit 0 RR0 0 Clock rate mul ...

    4 . 4 . 2 Clock Rate Multiplier A standard RS-232 serial port operates at a clock speed of 1.8432 MHz. In order to achieve higher data rates, Quatech Enhanced Serial Adapters can operate at two times , four times, or even eight times this standard clock speed. This is controlled by the clock rate multiplier bits in the Options Register. Software ca ...
