1.3 PRODUCT DESCRIPTIONS
The following product is maintained at the serial and catalog number level. The
descriptions included in this section give a brief overview of its functions and features.
1.3.1 1731N Mini Link Board for AT Style PC
The 1731N Mini Link Board is a full length card with dimensions and bus connections for
use in the IBM PC/AT style personal computer. The central processor for the Mini Link is
the 63B09E using an 8-bit bus and a 2 mHz dual phase clock. The processor board
checks message protocol and handles all data transfers between the ICN interface boards
and intelligent devices connected to the serial I/O board. Each ICN interface board
services direct communication with one ICN (up to 15 instruments).
The processor board keeps track of all message requests and responses. A request to
the processor board for foreground (display) data from a host device results in the data
being retrieved from the instrument ICN interface board which is automatically updated
every 250 msec. This permits the data to be sent immediately to the host. A request
from a host device for the background (tuning) data of an instrument is acknowledged with
a "wait and acknowledge" response. The instrument ICN interface board retrieves the
requested background data from the instrument and passes it to the processor board.
When all of the data for the deferred request is received by the processor board, it is
immediately transmitted to the host.
