Definition
IP0-IP7 Power Control
Latches power setting of the laser (effective during rising edge)
GND
Description: PIN10-15 have connected to the ground inside the fiber laser,
only need to connect control card GND with one of the Pins.
11
Low level, 1K resistance to GND
16,21
Warning signal
Description:16 low level,21 high level: Normal
16 low level,21 low level: temperature alarm
Emission Modulation input (PA)
19
HIGH= Emission ON
LOW=Emission OFF
20
Frequency Modulation (TTL)
Emergency Stop signal
High level: Normal; Low level: Emergency Stop (this function can be
selected in GUI)
23
Emergency stop signal is from low to high, need to detect the rising edge of
MO firstly, then the laser can be re-emitted.
Red beam ENABLE (Red Beam is preferred when Laser and Red Beam are
mutually exclusive. * refer to note2)
Pulse width adjustment ENABLE (Please refer to the following pulse width
22
control section for specific control mode).
High Level: Red Beam On
Low Level: Red Beam Off
MO signal for turn on/off
18
HIGH: ON
LOW: OFF
17,24,25 No need to connect
Note 1: 4.6-5.4V will be recognized as TTL high; 0-0.5V will be recognized as TTL low.
Note 2: Red beam Pin22 signal has higher priority than MO and PA signal. When Pin22 signal is
high, MO and PA signal will be shut down internally. The laser can be emitted by restarting MO
and PA after Pin22 signal is low, Priority mode can be set in GUI software.
