5.6.2 Emission external control
When both A1 and A3 of XP1 are set high, the laser is in the internal control mode, and the laser
emission is controlled by the computer software's light on button or through communication
sending"EMON" to control the light output, and "EMOFF" to control the light off; When A1 of XP1
is sethigh, A3 is suspended or set low, the laser is in the external control mode, the output light
isdetermined by the high and low TTLofthe MOD signals at A2 (XP1) andpin 1/2 (XP2).
5.6.3 Red light control
When both A1 and A3 of XP1 are set high, the laser is in the red light internal control mode,
andthe red light is controlled by the computer software red light button or through communication by
sending "ABN"or "ABF" command to control the ON/OFF of the red light; When A1 of XP1 is set
high, and A3 issuspended or set low, the laser is in external control mode, and the red light is
controlled by A5 of XP1
The red-light module in the laser works by means of communication, so there is a time delay of
at least 10ms when the red light is turned on and off.
When the red light is on, the laser cannot be set to Ready. Only after the red light is turned off
the laser can be set to “Ready”. (This limit can be changed, please contact Raycus Engineer).
5.6.4 Programming Mode
When A1 of XP1 is set high and A8-A14 is not 0, the laser is in “Programming Mode”. At this
time, thelaser emission is controlled by A2 of XP1, and the laser emission waveform is determined
by the editedwaveform.
