7.1.4.2 Interface Functions
The CPG 2500 responds to the following IEEE.488.2 interface functions:
SRQ Service Request: A service request is asserted whenever an error is encoun-
tered. When the bus controller issues a serial poll the error will be cleared. If the
host IEEE board includes automatic serial polling capability, turn this feature off
in order to view all errors.
LLO Local Lockout: The front panel keyboard of the CPG 2500 may be locked by
sending LLO or the command KEYLOCK ON.
GET Group Execute Trigger: When this message is received, the CPG 2500 will save
the current readings until the next time it is addressed as a talker.
GTL Go To Local: A GTL message will cause the CPG 2500 to return to local opera-
tion and unlock the keyboard.
DCL Device Clear: When this message is received, the CPG 2500 will clear all errors
and buffers and remain in the Remote mode.
SDC Selected Device Clear: The effect is the same as DCL.
EOI End or Identify: May be used as a command or query terminator in the place of,
or concurrent with, a terminating linefeed.
