7.5 Controls and ignition
This chapter describes how to program the controls and ignition of the JVM-104-
O08.
7.5.1 Input keys
The HMI JVM-104-O08 has the following 8 input keys:
[F1]
,
[F2]
,
[F3]
,
[F4]
,
[POWER]
,
[SCROLL],
[ESC]
and
[HOME]
. These input keys are user-program-
mable.
Special registers
In register 361000 of the JVM-104-O08 a bit-coded map of the input keys is avail-
able. You can use this map for programming.
The following registers are available for programming the input keys:
