IAV1S-B

The CHAPI IAV1S-B QBUS devices are implemented with CHAPI_IAV1S_B.DLL and use

CHAPI_INDIO.DLL and CHAPI.DLL for its implementation. The DLL is available in binary

only. This implementation can map its DAC lines to SENSORAY 2601, 2608 ADC/DAC

Ethernet boards.

This device cannot be configured using the legacy ‘parameter’ configuration method.

The configuration options are as follows:

load chapi DAC dll=chapi_iav1s_b.dll address=<>

set DAC trace_level=<trace_level>

set DAC port_dll=”<port_dll>”

set DAC port_cfg=”<port_cfg>”

set DAC port_param[0]="<IP address>"

set DAC port_offset[0]=<adc_offset>

Where :

• port_dll – The DLL file name to load CHAPI DAC port from. If omitted

CHAPI_INDIO.DLL will be used by default;

• trace_level – Debug trace level (0 - 10), 0 for NO traces or 10 for MAX traces. If omitted

zero will be used by default;

• port_cfg – The name of the port to load. Can be:

• 2600 – a SENSORAY 2601/2608 Ethernet ADC/DAC board port

If the port_cfg parameter is omitted, the port name “2600” will be used.

• port_param[0]

– IP address of SENSORAY 2601 board (where desired SENSORAY 2608 is

connected) where group of 4 DAC channels (situated on the IAV1S-B device) is to be mapped to, this

parameter must not be omitted;

• port_offset[0]

– offset for group of 8 DAC (situated on the IAV1S-B device) on the SENSORAY 2601

board (selected by port_param[0]) to select desired SENSORAY 2608 board, this parameter must not be

omitted

For information about any technical information about SENSORAY 2601/2608

Ethernet boards please refer to its manual (www.sensoray.com).

Examples:

#load IAV1S-B
