This pin signal can be sent to a microcontroller, or used for driving an LED through a buffer. The internal equivalent circuit of this pin is a 5k Ω pull-up resistor connected to a 5V rail in parallel with an open drain comparator output. The main specifications are shown in Table 1 below. TABLE 1. SPECIFICATIONS (TA = 25°C) monitor signals, and the Con2 is for connecting to the laser diode. A typical connection schematic is shown in Figure 4 below.
