Remote Control
Two 9 pin “D” type connectors are mounted on the rear panel which provide REMOTE-
INPUT-OUTPUT control and information. These connectors mate with standard 9 pin
“D” 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.

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 ). The signal outputs are provided on the 9-pin
female type D connector. Below is a listing that indicates what conditions activate each
