EnableRemote

Allow remote programming (by sending messages over the GPIB line) of a device.

Syntax

C EnableRemote(int board, short addresslist[])

Parameters

board is an integer which identifies the GPIB board to be used for this operation. In most

applications, this value is 0.

addresslist is an array of GPIB addresses, terminated by the value NOADDR. These

addresses identify the devices to be put in remote programming mode.

Returns

ibsta will contain a 16-bit status word as described in Appendix B, IBSTA.

iberr will contain an error code, if an error occurred.

Usage Notes

When this routine is executed, the system controller asserts the Remote Enable (REN) line

and the Controller addresses the specified devices as listeners.

Example

Places devices at GPIB addresses 6 and 7 (connected to GPIB board) in remote mode.

C short addresslist[3] = {6,7,NOADDR};

EnableRemote(0, addresslist);
