6. Interface
6.1 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:
6.1.2 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 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 / 125 VAC ( 0.5 ADC ). 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.
Pins 1 and 2 provide the PASS signal.
Pins 3 and 4 provide the FAIL signal.
Pins 5 and 6 provide the PROCESSING signal.
Pins 7 and 8 provide the RESET OUT signal.
