Where:

• port_dll[0] – is the name of DLL library from where the digital IO port for

DR11(C)/DRV11 device emulation is loaded;

• port[0] – name of digital IO port

for DR11(C)/DRV11 device emulation;

• 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.

• brq_priority

–

bus request priority level for DR11(C)/DRV11 device, If this parameter is

omitted, 4 is used as default

• pulse_width – time length of INIT / READ / WRITE pulses in approximately 450ns

units, If this parameter is omitted, 2 (i.e. 900ns) is used as default

Example:

load chapi DR11 dll=chapi_dr11.dll address=017767770 vector=0300 trace_level=0

set DR11 port_dll[0]=chapi_dr11_621_port.dll port[0]=dr11_621

set DR11 pulse_width=1 bus_no=1 device_no=7 function_no=0

DRV11-WA via SENSORAY 621

The CHAPI DRV11-WA QBUS device example is based on the SENSORAY 621 PCI

board, with the PPT.SYS device driver installed in the host system. It is implemented in

the CHAPI_DRV11WA_621.DLL and CHAPI_DRV11WA_621_PORT.DLL and uses

CHAPI_PARALLEL.DLL the and the CHAPI.DLL. The current CHAPI DRV11-WA via

SENSORAY 621 implementation requires a fast, low-latency host system.

For details about cables wiring from SENSORAY 621 connector to DR11(C)/DRV11

connectors see chapter 10.

The CHAPI DRV11-WA device is configured as follows:

load chapi IXA dll=chapi_drv11wa_621 trace_level=<trace_level>

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

set IXA port_dll=

chapi_drv11wa_621_port.dll

set IXA port_name=drv11wa_621

set IXA bus_no=...

set IXA device_no=...

set IXA function_no=...

set IXA busy_lo_delay=... busy_hi_delay=...
