Fig. 12-5 I/O connection
12.10.1 Overview and Functions
At the "I/O" connection, a 25-pin Micro DSUB plug, the ES820.1 and the ES830.1
module provides digital inputs and outputs with various functions:
Pin assignment see chapter “"I/O" Connection: Socket and matching Plug” on
page 178.
12.10.2 "Remote Power" Input
The "Remote Power" input ("I/O" connection, pin 11) enables the ES820.1/ ES830.1
module to be switched on and off remotely (e.g. from the passenger cell). The
external "Remote Power" button switches the input to ground. The function of the
external "Remote Power" button and the "Power" button on the module is identi
-
cal. The function of the "Remote Power" input can be configured.
