The SERVICE connector is a female DB9 interface. If PIN 6-7 are disconnected, the
laser will immediately stop working, and the laser Ready signal will go low.
The laser has pre-shorted the 6 and 7 pins before shipment. If it is not connected, the
InterLock error will be displayed after the laser is powered on.
CAUTION: The interlock cannot be connected to active signal, or error
will be caused, or even the product may be damaged.
4.4.2 Modulation Input
The 24V modulation signal should be applied to the connector as in Figure 14. A cable is
provided for the connector, which is shown in Figure 15. The MOD modulation signal
description is shown in Table 9, and the internal circuit of the modulation signal is as shown in
Figure 16.
