Remote reset
There are two methods of connection to a remote push button that will achieve the same effect as the RESET button on the front panel of the PI 200-3 interface. This may be useful if manual stylus changing is frequent, or if the PI 200-3 is difficult for the operator to access.
A momentary action push button or switch may be connected to pins 1 and 5 on the SCR200 miniature DIN connector on the rear panel. If the connector is already in use for connection of a SCR200 stylus change rack, a dual rack cable type PL97 may be used to provide an additional connector.
Alternatively, the button may be directly wired to the PPOFF and ground (0 V) pins (pins 2 and 3) on either of the PICS connectors on the rear panel of the PI 200-3.
