8.2.5 Remote Port
TTL compatible interface for operation with various peripherals including foot switch, remote controller and monitor output.
9-pin male D-type connector.
Signals with a name starting with ! are active Lo.
!RUN Input (Pin 3)
The !RUN input is an active Lo input with an internal pull-up resistor.
In the execution of programs, it is equivalent to pressing the RUN key on the front panel.
To use this with a foot-switch, wire the switch between this input and 0V.
!STOP Input (Pin 9)
The !STOP input is an active Lo input with an internal pull-up resistor.
The active-going edge of this input halts all Tester activity, turning off all signal sources.
To use this with an ‘emergency stop’ switch, wire the switch between this input and 0V.
Status Outputs (Pins 2, 4 and 6)
The status outputs are standard 5Volt logic signals.
In the standard set-up, the three status outputs are active Lo signals which duplicate the three LED’s on the front panel - Busy, Pass and Fail. They could, for example, be connected as status inputs to a robot controller, or a bin selector.
Beep Output (Pin 1)
This is an active Hi output which copies the internal beeper.
It is configured in the test program header (see the Test Editor section of this manual).
All the outputs (pins 1, 2, 4 and 6) are fitted with 1kΩ protection resistors, and therefore they cannot directly drive external high current loads such as indicators, or bin-select relays. Minimum input resistance of devices connected to these outputs to be 10kΩ.
