HP 27110A Standard HP-IB
Features
• IEEE-488-1978 compatible.
• Supports DMA with two modes of performance: High Speed Mode for operation with fixed
discs
or other high-speed peripherals, and Standard Mode for instruments and slower
peripherals.
• Supports up to 14 device loads.
• Selectable HP-IB controller or slave capabilities and parallel poll capabilities (BASIC Language

Configuration
The normal switch settings are shown in the next figure.
The switch functions are:
51-55: Address
30 (decimal); 51 is Least Significant Bit
56: System Controller On
57: Normal Speed
58: Test Mode 1
High-speed devices can run on a normal-speed bus, but run slower than their capacity. Normal-
speed devices cannot run on a high-speed bus. The following are high-speed devices:
• disc drives
• 7971A tape drive
.26085 and 2631B/G printers
