IEEE 488.2 functions
Table 2-3 contains IEEE 488.2 Functions.
ibrpp Performs parallel polling.
ibrsc Sends Interface Clear (IFC) message or Remote Enable (REN) message
to request or release the System Control.
ibrsv Requests service and changes the status byte of the sequential polling.
ibsad Sets or disables a board secondary GPIB address.
ibsic Sets the GPIB interface’s clear (IFC) line to enable at least 100ns if the
GPIB interface is system controller.
ibsre Sets or clears the Remote Enable (REN) line.
ibstop Stops the asynchronous I/O operation.
ibtmo Sets the board timeout period.
ibwait Monitors event(s) until one or more events that are described by mask or
delay operating occur.
ibwrt Writes data from a buffer to a device.
ibwrta Writes data from a buffer to a device asynchronously.
ibwrtf Writes data from a file to a device.
Table 2-3
IEEE 488.2 functions
Function Description
AllSpoll Polls one or more devices sequentially.
DevClear Sends the Selected Device Clear (SDC) GPIB message to clear
the selected device.
DevClearList Clears multiple devices.
EnableLocal Sends Go To Local (GTL) GPIB message to multiple devices to
allow local operation of the devices.
EnableRemote Sets Remote Enable (REN) line to allow remote programming of
devices.
FindLstn Finds listening devices on the GPIB bus.
FindRQS Sequentially polls devices to determine which device is requesting
service.
PassControl Sends Take Control (TCT) GPIB message . Sending this
message allows control to pass to another GPIB device having
control capability.
PPoll Performs parallel polling once.
PPollConfig Controls or releases GPIB data line to configure the device to
respond to parallel polling.
PPollUnconfig Removes configuration that allows device to respond to parallel
polling.
RcvRespMsg Reads data from a device.
ReadStatusByte Sequentially polls a device.
Receive Reads data bytes from a device and then stores them in the
assigned buffer.
ReceiveSetup Configures device and interface to a talker and a receiver.
ResetSys Resets and initializes the devices.
Send Writes data bytes from the buffer to the device.
SendCmds Sends GPIB commands.
SendDataBytes Sends data from the buffer to the device.
