SendSetup
Purpose
Set up devices to receive data in preparation for SendDataBytes.
Format
C
|
void SendSetup (int boardID, const Addr4882_t *addrlist) |
Visual Basic
|
CALL SendSetup (boardID%, addrlist%()) |
Interactive Control (Usage Notes)
|
Send addrlist |
Input
| boardID | The interface number |
| addrlist | A list of device addresses that is terminated by NOADDR |
Description
SendSetup makes the devices described by addrlist listen-active and makes the interface talk-active. This call is usually followed by SendDataBytes to actually transfer data from the interface to the devices. SendSetup is particularly useful to set up the addressing before making multiple calls to SendDataBytes; it eliminates the need to readdress the devices for every block of data.
Possible Errors
| EARG | Either an invalid address appears in addrlist or the addrlist is empty; Ibcnt is the index of the first invalid address in the addrlist array. |
| EBUS | No devices are connected to the GPIB. |
| ECIC | The interface is not the Controller-In-Charge; see SendIFC. |
| EDVR | The NI-488.2 driver is either configured incorrectly or is not properly installed. |
| EHDL | boardID is out of range. |
| ELCK | The requested operation could not be performed because of an existing lock by another process. |
| ENEB | The interface is not installed or is not properly configured. |
| EOIP | Asynchronous I/O is in progress. |
