Tag: Analog PTZ

ExacqVision Hybrid servers have the ability to integrate with Pelco Coaxitron CXTA 9760 devices. This allows customers with existing Pelco PTZ cameras that are controlled through the coax with the Coaxitron protocol to be controlled using ExacqVision software. The CXTA accepts the Pelco 422 protocol from the ExacqVision server, and it outputs the data over the video cable.<br><br>

To use a Pelco Coaxitron Translator (CM9760-CXTA) to control up to 16 analog PTZ cameras using an exacqVision Hybrid system, complete the following steps.<br><br>

I. Connect video from the CXTA to the exacqVision Hybrid system

Connect the BNC Out from the CXTA to Video In on the ExacqVision Hybrid system. The input/output numbers do not have to match because the CXTA input position determines where the PTZ commands are sent.<br><br>

II. Configure the CXTA dipswitches

Set CXTA dipswitches 1 and 2 to OFF to enable 32-bit extended Coaxitron.

Set dipswitch 3 ON to enable Pelco D protocol.

Set dipswitch 8 to ON to enable Spectra equipment type.

III. Connect RS-485 TX+/- on the ExacqVision Hybrid system to the OUT RJ-485 connector on the CXTA

NOTE: For this process, you need a CAT5 cable with one RJ-45 end, a wire stripper, and a small screwdriver.

1. On the end of the cable without the RJ-45 connector, strip wires 7 and 8 to expose the copper. If the cable is TIA standard, the wires are white/brown and brown.<br><br>
2. Locate the RS-485 terminal block on the back of the ExacqVision Hybrid system.<br><br>
3. Use a small screwdriver to loosen (not remove) the TX+ and TX- screws on the RS-485 terminal. You can remove the terminal connector to see the labels.<br><br>
4. Insert the brown wire into the TX+ position on the RS-485 terminal and tighten the screws.<br><br>
5. Insert the white/brown wire into the TX- position on the 485 terminal and tighten the screws.<br><br>
6. Plug the other end of the CAT5 cable into the OUT RJ-485 connector on the CXTA.<br><br>

IV. Enable the serial port in the ExacqVision Client software

1. In ExacqVision Client, open the Configuration page.<br><br>
2. Select Serial Port Setup.<br><br>
3. Locate the RS-485 connection. In Windows, the highest numbered COM port is typically where the RS-485 connection communicates.<br><br>
4. In the Use column, select PTZ from the drop-down list.<br><br>
5. Give the connection a name (Pelco CXTA, for example).<br><br>
6. In the Profile/Protocol section, select Pelco-D from the drop-down list.<br><br>
7. In the Baud Rate column, select 2400 from the drop-down list.<br><br>
8. In the Data Bits column, select 8 from the drop-down list.<br><br>
9. In the Stop Bits column, select 1 from the drop-down list.<br><br>
10. In the Parity column, select None from the drop-down list.<br><br>
11. Leave Flow Control at None and Max Line Length at 80.<br><br>
12. Click Apply.<br><br>

V. Enable PTZ control on the camera and test it in the exacqVision Client software

1. In ExacqVision Client, open the Configuration page.<br><br>
2. Select the first input that you want to configure as a PTZ camera to open the Camera Setup page. The inputs are listed below the Camera Recording Setup icon in the configuration tree.<br><br>
3. In the Serial Port drop-down list, select the COM port enabled in the previous steps.<br><br>
4. In the Address drop-down list, select the address that matches the camera’s input on the CXTA. For example, if the camera is connected to Input 6 on the CXTA, select 6 as the address.<br><br>
5. Click the Presets button on the left (not the digital Presets button).<br><br>
6. Click the Pan/Tilt buttons to move the camera around.<br><br>
7. Click the Zoom buttons to zoom in and out.<br><br>
8. Repeat steps 1-7 for each of the cameras connected to the CXTA that you want to configure as PTZ cameras.<br><br>
