Appendix E - SMC-LSR-05 Coherent C70 Laser Adapter
1040-0011 Revision 86
Pins (1 –12)
VOLTAGE_OK_BUF
24V capable buffered version of the VOLTAGE_OK_IN signal from J5
5
GND
Digital ground reference
6
CHASSIS
Chassis ground reference
7
LASER_MOD_OUT
Laser modulation signal. Same as J5 pin 1
8
LASER_LOCAL_MOD_SUPPLY
Voltage source for external circuitry that control local modulation behavior
9
LASER_LOCAL_MOD_CONTROL
Analog input control signal for regulating the duty-cycle of a local 10KHz
modulation source
10
LASER_LOCAL_ENABLE_N
If switched to GND, the local laser modulation source will be applied to the
LASER_MOD_OUT outputs on J5 pin 1 and to J2 pin 8. If not connected, the
SMC LASER_MOD1 modulation will be selected.
11
GND
Digital ground reference

9.4 LOCAL LASER MODULATION CONTROL
The Coherent C70 Laser Adapter provides support for generating a laser modulation signal without
the SMC being involved. This mode of operation is intended for service applications where remote
control of the laser on/off state and power are needed during optical system alignment. It is possible
to connect a cable with a potentiometer and open/close switch to use this mode. When the switch is
closed, the local modulation feature is enabled. The variable resistor adjusts the duty cycle of the
pulse waveform, and hence the laser power. The following figure illustrates how to attach an
external cable assembly that enables this feature.
