1100.4903.12 8.15 E-8
The 15-pin SUB-D female connector AUX 4 on the rear panel is used as an input or output for status,
control, and trigger signals. These signals are applied to definite pins of the AUX 4 connector (refer to
the corresponding menu).
The pin assignment of the AUX 4 connector is as follows:
AUX 4
1
10
5
15
6
11
