General description

CHARON-AXP supports emulation of PBXDA-xx family PCI serial adapter based on DIGI AccelePort serial adapters via CHARON PCI Pass Through mode (using a specific CHARON PCI Pass Through driver) and by direct virtualization.

CHARON PCI Pass Through mode enables connection between the virtual PBXDA-xx PCI serial adapter and the physical DIGI AccelePort PCI serial adapter plugged into a hosting server PCI bus whether as the direct virtualization may address the host serial port or TCP/IP port.

Virtual PBXDA-xx PCI serial adapter

Loading virtual PBXDA-xx serial lines adapter

Syntax for loading PBXDA (AccelePort 2r 920) serial lines adapter:

...

The numbers in the square brackets represent line number on the virtual PBXDA-xx adapter starting from 0.

Info

All the parameters described in the "Placement of peripheral devices on PCI bus" chapter, such as "bus", "device", "function", "irq", "irq_bus" are applicable for PBXDA-xx controller.


Note

DIGI drivers for OpenVMS and Tru64 are sensitive to PBXDA-xx location on PCI, therefore it is recommended to fix PBXDA-xx location with explicit configuration.

For exampleExample:

load

PBXDA

TXA

bus=pci_1

device=4

function=0

Configuration parameters

The PBXDA-xx PCI serial adapter emulation has only one configuration parameter:

host_bus_location

Parameterhost_bus_location
TypeText String
Value

Establish connection between virtual PBXDA-xx PCI serial adapter and physical DIGI AccelePort PCI serial adapter installed on CHARON host (pass through mode)

Syntax:

load digi <controller name> host_bus_location="PCI bus X, device Y, function Z"

where:

ParameterDescription
"PCI bus X"PCI bus number of the host  DIGI AccelePort PCI serial adapter
"device Y"PCI bus device number of the host  DIGI AccelePort PCI serial adapter
"function Z"The "function" parameter of the the host DIGI AccelePort PCI serial adapter

Example:

load digi SERIAL_A host_bus_location="PCI bus 3, device 1, function 0"

Installation of  DIGI AccelePort PCI serial adapter

  1. Install the DIGI AccelePort PCI serial adapter to some spare PCI slot of the host system
  2. Boot a Windows operating system
  3. Open “Computer Management”
  4. Select “Device Manager”
  5. In the right window select the desired physical serial adapter connected to the system, right-click the mouse button, and the corresponding menu will appear.
  6. From the menu select “Update driver…”. Windows will show “Hardware Upgrade Wizard”
  7. Select “No, not this time”, click “Next”
  8. Select “Install from a list or specific location (Advanced)”, click “Next”
  9. Select “Don’t search. I will choose the driver to install”, click “Next”
  10. Click “Have Disk…”. Windows shows dialog “Install From Disk”
  11. Instead of “A:\”, click “Browse” and select path to the folder in which driver’s INF file is located (typically "C:\Program Files\CHARON\Drivers\DIGI_X.X.0.XXXXX"), select “digi_ppt_amd64.inf”, and click “Open”
  12. The “Hardware Upgrade Wizard” should have “CHARON DIGI adapter”. Select it, and click “Next”
  13. There will be one or two more dialogs, but they are usual for device driver installation.
  14. Reboot the host
