7. Connection of Remote I/O
Two 9-pin “D” type connectors are mounted on the rear panel that provide REMOTE-
INPUT-OUTPUT control and information. These connectors mate with standard 9 pin
D-sub-miniature 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)

7.1. Signal Outputs on Remote I/O
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 / 125 VAC (0.5 ADC / 30 VDC). The signal outputs are
provided on the 9-pin female D connector. Below is a listing that indicates what
conditions activate each pin. When a terminal becomes active the relay closes thereby
allowing the external voltage to operate an external device.
