USBDIO and Serial Port Recovery

The following recovery enhancements have been added to exacqVision Server:

  1. USBDIO recovery enhancement: version 6.7.20.74529
  2. UART serial ports recovery: version 6.7.25.75004

<br>

When a USBDIO or UART serial port device disconnects, exacqVision Server attempts to reconnect to the device after one second. If that attempt fails, the next attempt occurs after two seconds, and then four seconds, eight seconds, 16 seconds, and so on. This occurs until the device reconnects, or until the following maximum intervals are reached:

  1. USBDIO: 300 seconds
  2. UART serial ports: the same as the IP Camera reconnection interval

RS-485-to-USB Adapter Compatibility with ExacqVision

Two RS-485-to-USB adapters have been tested for compatibility with exacqVision: B&B Electronics, model 485USB9F-4W and VSCom, model USB-COMi-TB. The tests used the drivers supplied with the devices, and data has successfully been transmitted and received to and from each adapter. They were also tested in a loopback configuration with the RS-485 port built into an exacqVision server equipped with an analog capture board.


B&B Electronics, model 485USB9F-4W

VSCom, model USB-COMi-TB


Installation

  1. Install the adapter driver (included with the device or downloaded).
  2. Plug the device in to the USB port of the exacqVision server.
  3. Ensure that Windows discovers and configures the device properly. (Use Device Manager, found in Control Panel.)
  4. Restart the exacqVision Server service.
  5. In exacqVision Client, open the Serial Ports page.
  6. Verify that a new COM port exists in the UART section of the Serial Ports page.
  7. Configure the port as you normally would for PTZ control output or POS data input.

Notes

  1. The B&B adapter is equipped with a standard D-sub, 9-pin, female connector on the RS-485 side. A pinout diagram is included with this device.
  2. The VSCom adapter has terminal blocks on the RS-485 side, allowing easy connection of bare wires. The dip switches and jumpers were left in their default settings for testing.

Connecting an ExacqVision Hybrid System to a Pelco Coaxitron Translator for Analog PTZ Control

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>

Attached are the Pelco documents on the CXTA model.

Does the ExacqVision Client Support Multiple Monitors?

Yes, ExacqVision Client supports multiple monitors. We have tested up to four VGA monitors from a single workstation.

Typically, a user will run one instance of the ExacqVision Client per monitor. Because decompressing video is CPU-intensive, we recommend one core per Client for the best user experience. To drive up to four VGA monitors, we recommend an Nvidia T1000 graphics card. For always-on, higher end multi-monitor displays consider the Nvidia RTX A-2000 up to the Quadro GV100 discrete graphics cards.

The Nvidia P2000 has been tested running the ExacqVision Client with VGA and DVI monitors up to 1920×1200 resolution.

What types of microphones are compatible with the ExacqVision Hybrid NVR?

When using the audio input terminals on the rear of an ExacqVision Hybrid NVR, you will need a microphone with a a pre-amplifier capable of producing a line level output that can be connected directly to the ExacqVision audio terminal inputs.

If using a mic level output microphone, you will need a mic pre-amp to boost the audio to line level output for connection to the rear audio input terminals.

There are many options available in the market. The following is a list of some common choices:

  • Louroe ASK-4 #101 Single-Zone Kit
  • Louroe ASK-4 #102 Single-Zone Kit
  • Louroe ASK-4 #104 Four-Zone Kit
  • Louroe ASK-4 #108 Eight-Zone Kit
  • AKG PZM10 LL Microphone with line level output
  • AKG PZM11 LL Microphone with line level output
  • ETS SMI-9 Eight-Zone Kit

If you choose to use other surveillance or boundary layer microphones with mic level or XLR connection outputs you will need an intermediary device that provides a line level output to use with the audio input terminals.
