HARDWARE CAPABILITY
The following paragraphs highlight the interface features.

Address Decoding
This circuitry monitors the address lines to recognize when the GPIB I/O address is present on the IBM PC I/O channel and enables read and write access to the GPIB interface controller.
Buffering and Data Routing
Bi-directional internal bus handles data transfer between the IBM PC I/O channel and the GPIB interface controller.
Interrupt Arbitration
This circuit recognizes when interrupts have been enabled or disabled and passes or inhibits them accordingly.
DMA Arbitration
The DMA arbitration circuit recognizes when DMA operations are enabled or disabled and when the last transfer has taken place. It also routes the DMA request and acknowledge signals to the selected DMA channels.
Configuration Switches and Jumpers
These components determine the I/O port address, the DMA channel pair used, and the interrupt request line used.
GPIB Interface Controller
This integrated circuit, the NEC uPD7210 implements virtually all of the IEEE-488 interface functions. Twenty one program registers are used to configure pass commands and data to and from the GPIB.
GPIB Transceivers
The GPIB interface controller is interfaced to the IEEE-488 bus by National Semiconductor 75160A and 75162A transceivers. These ICs are specifically designed to provide power-up/power-down bus protection ( glitch free ). The AX5488 counts as one IEEE-488 bus load, thereby allowing an additional 14 devices to be connected before exceeding the bus loading restriction.
