1.1 DESCRIPTION

The 1733N Mini Link/EXT (External) 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 1733N Mini Link/EXT supports one ICN

and the 1732N ICN Interface Board supports a second ICN. The External 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.
