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