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:
205204-4 PLUG SHELL WITH GROUND INDENTS
205203-3 RECEPTACLE SHELL
745254-7 CRIMP SNAP-IN PIN CONTACT (for plug)
745253-7 CRIMP SNAP-IN SOCKET CONTACT (for receptacle)
745171-1 SHIELDED CABLE CLAMP (for either plug or receptacle)
747784-3 JACKSCREW SET (2)
6.1. Remote Signal Outputs
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. These are normally open free contacts and
will not provide any voltage or current. The ratings of the contacts are 1 AAC /
