Analog Output Ports
The RTC
®
5 provides two general purpose 12-bit
analog output ports, ANALOG OUT1 and
ANALOG OUT2
(1)
.
For programming the outputs see "12-Bit Analog
Output Ports", page 204.
The output voltage range of both analog output
ports is set to 0 V … 10 V.
Both signals are referenced to PC ground (GND). The
maximum current load of both signals is 5 mA.
I/O Circuits
Figure 11 shows the I/O circuits of the 15-pin D-SUB
connector for the laser.
(1) The ANALOG OUT2 signal is also available
via the MARKING ON THE FLY connector (see page 51).
