.5 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 interface. Such a
facility may be useful if manual stylus changing is to be frequently used, or if the PI 200
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 (refer to
table 8, cable no. 11) 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.
