Page 6 AXIS 212 PTZ/ AXIS 212 PTZ-V Installation GuideCompleting the installation1. Use a blower to remove dust from the lens.2. Clean the dome with a dry soft cloth to remove dust and finger prints (for AXIS 212PTZ-V only).3. Mount the casing using the supplied tamper-proof screws and screw driver.For AXIS 212 PTZIf using the angled wall mount, hook the side of the casing onto the tab on the angledwall mount (see page 4) and secure the dome casing on the other side using a tamper-proof screw.For AXIS 212 PTZ-VIf using the angled wall mount, place the dome casing onto the angled wall mount (seepage 4) making sure that the dome casing fits into the slot between the two tabs, andsecure the dome casing on the other side using a tamper-proof screw.4. Refer to Setting the IP address on page 7 for information on how to assign an IP addressto the AXIS 212 PTZ/AXIS 212 PTZ-V.The installation is now complete.I/O terminal connector blockPin Function Description4 TransistorOutputWith a maximum load of 50mA and a maximum voltage of 24V DC, this outputhas an open-collector NPN transistor with the emitter connected to the GNDpin. If used with an external relay, a diode must beconnected in parallel with the load, for protection against voltagetransients.3 DigitalInputConnect to GND to activate, or leave floating (or unconnected) todeactivate.2 3.3V DC Can be used to power auxiliary equipment, max 50mA.1 GND
