IBSRE
Asserts/Unasserts the REN (Remote Enable) line.
Syntax
C
ibsre (int board, int ren)
Parameters
board
is an integer containing the board handle.
ren
specifies whether the
REN
line is to be asserted or unasserted. If
ren
is zero, the
REN
line
is unasserted. Otherwise, the
REN
line is asserted.
Returns
ibsta
will contain a 16-bit status word as described in Appendix B,
.
iberr
will contain an error code, if an error occurred. The
ESAC
error is generated if the
specified GPIB interface board is not the system controller. Contains the previous
REN
state
if no error occurs.
Usage Notes
This routine can only be used if the specified GPIB interface board is the system controller.
Even though the
REN
line is asserted, the device(s) is not put into remote state until is
addressed to listen by the Active Controller. When the REN line is unasserted, all devices
return to local control.
Example
This example puts the device at MLA 12 (2C hex, ASCII ,) and associated with GPIB
Interface Board 1 in remote mode.
C
int gpib1:
gpib1 = ibfind ("GPIB1");
ibsre (gpib1, 2);
/* Use any non-zero
value */
ibcmd (gpib1,",", 1);
