4.0 Controlling the RELAY switching

4.1 Overview

The programmer controls the +12V supply to the relay coils by enabling the electronic 'EXT-VCC'
switch inside the programmer. This switch applies the voltage from the 'EXT-VCC' input (+12V) to the
relay coils. This causes the relays to switch so that the internal programmer I/O and power signals are
now connected to the Target System (UUT).

4.2 Controlling the RELAYs from EDS (Development Mode)

The simplest way to familiarise yourself with the operation of the RELAY switching is to make an
