Videolarm qmrt2-50na Guia Do Utilizador

NOTE:  This hi-res color camera uses a 1/4" chip and a 3-6mm 
             auto iris lens. It is comparable to a 1/3" chip using a 
             4-9mm auto iris lens.

The operational settings are defined by four dip switches located on 
the side of the PC Board (Figure 12 and 13). Moving the switches 
to the UP position will activate specific settings. Refer to the chart 
below.

The cameras included in the Q-View™ series have the option of  
transmitting video signals to NVT receivers via unshielded twisted 
pair cable. You must purchase the receiver separately. Instructions for 
connecting the receiver end of the the unshielded twisted pair cable 
will be included with the NVT receiver. Following are instructions for 
connecting the unshielded twisted pair cables to the RJ45 (Cat. 5) 
cable running outside your housing.

UNSHIELDED TWISTED PAIR 

VIDEO WIRING

1. Video for all four cameras is contained in the one RJ45 (Cat. 5) 
    cable. An RJ45 female coupling is provided so that all connections 
    can be made with an RJ45 connector. The following is the wiring 
    diagram for the four twisted pair wires that are included with the 
    Cat. 5 cable.

NOTE:  The customer must purchase the Video Transceiver from 

             NVT.  Part numbers are:
                       • NV-212A (500 ft.)
                       * NV-213A or NV-213A-M (1000 ft.)
                       • NV-652R, NV-862R, or NV-1662R (3000 ft.)

Once all connections and adjustments have been made reattach the 
trim ring/dome assembly by pressing in and sliding the three flat 
springs into the housing (Figure 15).  Make sure the springs are 
aligned with the three spring slots. You will feel all three springs snap 
into place when the dome is correctly secured into place.  Rotate the 
dome for final proper positioning of the liner and camera.
