PXL-500 Setup With a USB-Serial Adapter

This guide explains how to setup a connection to a PXL-500 Primary controller using a USB-serial adapter.


Keyspan adapter


The adapter used in this example is the Keyspan 19-HS by TRIPP-LITE - a USB-Serial adaper that Keri Systems recommends. It is robust, durable and is compatible with all Doors.NET supported Windows operating systems - Keri also supplies a plug-on comms module that supports an RS-232 and a USB connection.


This document assumes you have already successfully installed the drivers for your USB-serial Adapter and you have successfully installed and licensed Doors.NET and you have the PXL gateway setup and online:


In summary: the USB-serial adapter connects to the host PC via a USB cable - (maximum length is 3m/10 feet) - a serial cable is then wired into the TB12 connector of the PXL controller -(maximum length 15m/45 feet) and connects to the adapter using the D-plug at the opposite end), as shown below:



1.0Setup Instructions
  1. Plug in the USB-serial adapter into an available USB port of the host PC.
  2. Go to Device Manager on the host PC and check which COM port has been assigned to the adapter. Make a note of the COM port number.

  7. Verify that the controller's JP6 and JP7 jumpers are shorted.

  8. Ensure you have performed a factory reset if the controller is brand new or if the controller has come from a Doors32 installation.
  9. Log into Doors.NET (the default username and password are both admin)
  10. Once logged into Doors.NET go to Setup >> Hardware Setup >> All.
  11. The PXL gateway will be listed at the top of the hardware tree.
  12. Highlight the PXL gateway and check it is online.

  13. With the PXL gateway still highlighted click the Add PXL icon.
  14. Enter a new description for the PXL and select the exact controller model (if you know it) - it doesn't matter if you don't because the controller model will be automatically detected when the controller comes online.
  15. Click the APPLY button and the new PXL controller will be added to the hardware tree.

  16. A new Communications Channel must now be created so select Communications Channels
  17. Click the Serial Option and New Channel will appear in the hardware tree.
  18. Select New Channel
  19. Enable the channel then enter a new description for the channel.
  20. In the Comm Port field enter the COM port that is assigned to the USB-to-Serial adapter.
  21. Then save the communication channel settings.

    Note: if the USB-to-serial adapter was connected to the PC when the PXL gateway was created, then a communication channel will have been automatically created. Feel free to rename and use this communications channel rather than setting up a new one:

    Default Channel

  22. You must now select the PXL controller in the hardware tree.
  23. In the controller properties, look for the Communication Channel setting.
  24. Assign the new Serial comms channel that you created.

  25. Save the controller settings and within a few seconds the controller should come online.

  26. If it doesn't, try restarting the PXL gateway service.



2.0Troubleshooting Information
  1. Ensure the Primary PXL is addressed as #1.
  2. Verify jumpers JP6 and JP7 are across both sets of pins.
  3. If the adapter is showing in Device Manager is the assigned COM port number displaying.
  4. Is the assigned COM port number correctly defined in the Doors.NET communications channel which is assigned to the controller?
  5. Is the USB-serial adapter on Keri's recommended peripherals list?
  6. Is the adapter correctly installed? and displaying in Device Manager of the host PC.
  7. If the adapter is showing in Device Manager is the assigned COM port number displaying?
  8. Does the USB cable length exceed 3 metres?
  9. Does the serial cable run length exceed 15 meters/45 feet?
