DESCRIPTION

The 1731N Mini Link with 1732N ICN Interface Board, Figure 1-1, provides a general
purpose serial interface to MOD 30 and MODCELL instruments via the Instrument
Communications Network (ICN). The 1731N Mini Link supports one ICN and the 1732N
ICN Interface Board supports a second ICN. The Mini Link provides intelligent buffers that
enable the operation of higher level devices (such as personal or other computers) by:

Assembling display and tuning information for a number of instruments and storing the
data in block format. This relieves the host from executing individual requests and
improves the efficiency of the communications.

Permitting the host device to download and upload instrument configuration
information. This enables instrument configuration to be performed at a central
location using a personal computer that can easily display, manipulate and document
data.

Permitting limited peer-to-peer communications between ICNs.

Providing diagnostic checks for message validity resulting in secure general purpose
serial interfaces to the ICN.

Off-loading trend functions when supported by the host application software.
