• port_dll – is the name of DLL library from where the DRV11-WA device emulation is

loaded. If this parameter is omitted, CHAPI_DRV11WA_621_PORT.DLL is used as

default;

• port_name – the name of DRV-11WA replacement adapter connection module to load

from the specified DLL library. If this parameter is omitted, 'drv11wa_621' will be used

as default;

• bus_no, device_no, function_no

SENSORAY 621

PCI card location description.

These numbers should be gathered from the Windows hardware wizard after Sensoray

621 PCI board installation.

• busy_lo_delay - BUSY signal delay in LOW level in approximately 450ns units. If this

parameter is omitted, 0 is used as default

• busy_hi_delay - BUSY signal delay in HIGH level in approximately 450ns units. If this

parameter is omitted, 0 is used as default

Example:

load chapi IXA dll=chapi_drv11wa_621.dll trace_level=0

set IXA bus_no=1 device_no=7 function_no=0

set IXA busy_lo_delay=0 busy_hi_delay=0

DRV11-WA

The CHAPI DRV11-WA QBUS device example is based on the DCI-1100 PCI board from

The Logical Company, with the DCI1100.SYS device driver installed in the host system. It

is implemented in the CHAPI_DRV11WA.DLL (in binary form) and uses the

CHAPI_HW.DLL and the CHAPI.DLL. Note that the DCI-1100 is end of life as it does not

meet the RoHS environmental requirements. The current CHAPI DRV11-WA

implementation requires a fast, low-latency host system and is only provided as an

example, instability has been observed in some test configurations. It is recommended to

develop a custom parallel I/O CHAPI device with the appropriate host interface for a

specific project.

The CHAPI DRV11-WA device is configured as follows:

load chapi IXA dll=chapi_drv11wa trace_level=<trace_level>

set IXA address=... vector=...

set IXA adapter_dll=chapi_hw

set IXA adapter_name=dci1100

set IXA adapter_instance=0

set IXA adapter_options=""
