The first PC hosts two programs modules linked via standard TCP/IP socket: • The “Instrument Level Test” module (MEXILT) to be used only at instrument level test • The “Command and Display Module (SCOE) to be used both at instrument and system level test.

This module, during the instrument level tests, is connected to MEXILT using the same (Internet domain stream socket) protocol used by CCS in order to be used with only minor modifications at system level test. At system level test this module is connected to CCS. 1.
