OPERATION
D. CONNECTION OF REMOTE I/O:
A 9-pin “D” type connector is mounted on the rear panel which provides REMOTE-
INPUT-OUTPUT control and information. This connector mates with standard 9-pin
“D” subminiature connector provided by the user. The Remote I/O 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.
205203-3 RECEPTACLE SHELL
745253-7 CRIMP SNAP-IN SOCKET CONTACT (for receptacle)
745171-1 SHIELDED CABLE CLAMP (for either plug or receptacle)
747784-3 JACKSCREW SET (2)
REMOTE INTERFACE REAR PANEL:
1. SIGNAL OUTPUTS ON REMOTE I/O
The rear panel connector provides output signals to remotely monitor PASS, FAIL,
and PROCESSING conditions. These signals are provided by three normally open
internal relays that switch on to indicate the current condition of the tester. These are
normally open free contacts and will not provide any voltage or current. The ratings
of the contacts are 1A / 250 VAC ( 0.5 ADC ). 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.
Pins 6 and 7 provide the PASS signal.
Pins 8 and 9 provide the FAIL signal.
Pins 1 and 4 provide the PROCESSING signal.
