If you use cores from two different pairs in the CAT5 cable you will not get the benefit of the shielding effect

of the cable twists and the dome will function erratically. You must always use a core from a PAIR, not two

cores from two different pairs!!

Connecting the video out of the dome.

The dome has a short BNC lead attached to it, this is the lead that carries the video signal from the

built-in camera. You need to extend this lead to the “VIDEO-IN” of the DVR or monitor. Use a

good quality RG59 coax cable or similar to do this.

TIP – If you can’t get a picture at the remote end you could always take your test monitor to your

PTZ dome and check the picture quality on its own short BNC lead.

If you’re testing the equipment on a workbench you now have a one dome system.

For setting up the keyboard and testing the dome please read sections on default Dome settings and

using the keyboard.

You can use a keyboard or a suitable DVR to control the dome. A suitable DVR would be one with

PTZ functionality built into it and preferably Pelco-D protocol. If your DVR has a list of protocols

it’s always best to try “Pelco-D” first. In the DVR, with Pelco-D set, you must also make sure you

set up the “baud-rate” to 2400.

A typical site installation would look like the following diagram on the next page.

It shows the dome connected to the keypad plus how the dome could also be connected to a DVR

instead of the keypad or at the same time. DVR’s that have the capabilities of PTZ control will have

a terminal or connection on them somewhere, where the dome’s RS485+ A and RS485- B line can

connect to. Please refer to the individual DVR instructions of how to do this.
