6. CONNECTION OF REMOTE I/O

Two 9 pin D-type connectors mounted on the rear panel provide REMOTE-INPUT-

OUTPUT control and information. These connectors mate with a standard 9 pin D-

type subminiature connector provided by the user. The output mates to a male (plug)

connector while the input mates to a female (receptacle) connector. For best

performance, a shielded cable should be used. To avoid ground loops the shield

should not be grounded at both ends of the cable. Suggested AMP part numbers for

interconnecting to the Remote I/O are shown below:

JACKSCREW SET (2)

The rear panel connector provides three output signals to remotely monitor PASS,

FAIL, and PROCESSING conditions. The monitoring signals are provided by three

normally open internal relays that toggle ON and OFF to indicate the condition of the

tester. The RESET OUT pulse signal and the START OUT pulse signal are also

provided by a normally open internal relay. The RESET OUT gives a signal whenever

the RESET function is activated. This can be used to abort a Hipot test while the units

are interfaced as a test system. The START OUT gives a momentary output pulse
