Send Function

bus The function addresses the interface indicated by bus as a Talker.

bus refers to the GPIB bus number. If you have only one GPIB interface in your computer, the default bus number is 0. Refer to the software installation instructions included with your GPIB controller for additional GPIB interfaces.

address addresses the device indicated by address as a Listener.

If you do not wire address, the function sends data string with no addressing, thereby sending it to all previously addressed Listeners. To send data string to several devices, use the SendList function. If a secondary address is required, use the MakeAddr function to format the primary and secondary addresses properly.

mode describes how to signal the end of the data to the Listener.

This input accepts the following values.

0	Do nothing to mark the end of the transfer (default).
1	Send NL (linefeed) with EOI after the data bytes.
2	Send EOI with the last data byte in the string.

data string contains the data bytes that the function sends to the GPIB device.

error in describes error conditions that occur before this node runs. This input provides standard error in functionality.

status is a Boolean array in which each bit describes a state of the GPIB Controller.

If an error occurs, the function sets bit 15. GPIB error is valid only if bit 15 of status is set.

The following table shows the numeric value and symbolic status of each bit in status. This table also includes a description of each bit.

Status Bit	Numeric Value	Symbolic Status	Description
0	1	DCAS	Device Clear state
1	2	DTAS	Device Trigger State
2	4	LACS	Listener Active
3	8	TACS	Talker Active
4	16	ATN	Attention Asserted
5	32	CIC	Controller-In-Charge
6	64	REM	Remote State
7	128	LOK	Lockout State
8	256	CMPL	Operation Completed
12	4096	SRQI	SRQ Detected while CIC
13	8192	END	EOI or EOS Detected
14	16384	TIMO	Timeout
15	-32768	ERR	Error Detected

byte count refers to the number of bytes that pass over the GPIB.

error out contains error information. This output provides standard error out functionality.
