The Remote connector (shown in Figure 1–4) provides a user interface for
contact-closure remote control. The AM700 may use this port to control external
devices that are actuated via a contact-closure. The TTL-Level input may be used
with external contact-closure relay or switch to initiate an action for the AM700. A
possible use of this feature is to use a foot switch to signal the AM700 in a running
function for production line testing. This type of operation leaves the operator’s
hands free to make connections to the equipment under test and operate the AM700
making the measurements without having to have immediate access to the front
panel of the AM700. A function program has to be written with the appropriate
commands to make use of the remote connector for the operation just described.
