Page 6: General Information
The shared interrupt feature minimizes the system resources consumed by the adapter. In order to support the use of the shared interrupt feature of the ES-100D, Quatech has developed device drivers for several popular operating systems and environments. The sales department can be contacted for details on current offerings. -

Page 9: Addressing Ports
The base address of the ES-100D can be set anywhere in the range of 0000 hex to FFFF hex. Each serial port on the ES-100D uses 8 consecutive I/O locations. The ports reside in a contiguous block of I/O space in eight byte increments, for a total of 64 contiguous bytes. - Page 10 Position 6 of SW2 is used to enable or disable the interrupt status register. Factory default setting --- 0300 hex (no digits) Another Example --- 5AC0 hex (no digits) Figure 5 --- Serial port base I/O address selection switches Quatech ES-100D User's Manual...

Page 11: Interrupt Level (Irq)
INTERRUPT LEVEL (IRQ) The ES-100D allows the use of any interrupt level in the range IRQ2 to IRQ7, IRQ10 to IRQ12, IRQ14, or IRQ15, selected using jumper pack J2. In Figure 6, the factory default setting of IRQ3 is shown. To select a different IRQ, move the jumper to the appropriate position on J2. - Page 12 Scratchpad Register Interrupt Status Register Slide position 6 of SW2 toward the top of the ES-100D to enable the interrupt status register, or toward the bottom of the ES-100D to disable it. Figure 7 --- Enabling the Interrupt Status Register When a hardware interrupt occurs, reading the interrupt status register will return the interrupt status of the entire ES-100D, as shown in Figure 8.

Page 17: Serial Port Functional Description
SERIAL PORT FUNCTIONAL DESCRIPTION This section contains information intended for advanced users planning to do custom programming with the ES-100D. The information presented here is a technical description of the interface to the 16450 or 16550 UART. The 16450 UART is an improved functional equivalent of the 8250 UART, performing serial-to-parallel conversion on received data and parallel-to-serial conversion on output data. -

I/O address. This I/O address is determined by adding an offset to the base address set for the particular serial port. The base address is set using DIP switches on the ES-100D (see section III). -
Page 19: Interrupt Enable Register
During this time, new interrupts are detected by the UART, but are not reported in this register until the access completes. For the 16550 only, this register can be used to indicate whether the FIFO mode is engaged by examining bits 6 and 7.

XRST --- Transmit FIFO reset (16550 only): When set (logic 1), all bytes in the transmitter FIFO are cleared and the counter is reset. The shift register is not cleared.

Page 24: Line Status Register
The bits are reset by reading the line status register. In 16550 FIFO mode, these bits are associated with a specific character in the FIFO and the exception is revealed only when that character reaches the top of the FIFO. Quatech ES-100D User's Manual... -

Page 30: Troubleshooting
Any unauthorized repairs or modifications will void the ES-100D's warranty. Computer will not boot up. 1. Is the ES-100D properly inserted? Remove the card and try again. Perhaps try a different expansion slot. 2. Is the base address correctly set? Check for address conflicts with other devices in the system. - Page 31 Version 1.01 March 2004 Part No. 940-0099-101 Quatech Inc, ES-100 Manual...
