(2) Listener functions
●
Multiple listeners can exist on the GP-IB (IEEE488) bus at the same time.
●
When the ATN signal from the controller is the High level, reads data from the bus.
●
Performs acceptor handshake automatically.
●
Specified as a listener when MLA (My Listen Address) is received from the controller.
●
Listener is canceled when MTA (My Talk Address) is received from the controller.
●
Listener is canceled when UNL (Unlisten) is received from the controller.
Like talkers, bus command reception may be disabled (hang-up) also in case of listeners.
To cancel this condition, it is necessary to send IFC (uni-line message) or DCL (multi-line message) to
the TS-3200A. Normally, it is not necessary to press the system reset of the TS-3200A.
Usually, listener specification is executed first for the PRINT statement (OUTPUT statement) and talker
specification first for the INPUT statement of the personal computer, resulting in no problem.
(3) Bus commands
Effective bus commands (multi-line messages) for this interface are shown below. Other commands are
ignored (without affecting operation).
1: LLLLL Listener dress
2: TTTTT Talker address
Note: The DC function (device clear function) of the TS-3200A only initializes this interface at the
same time as IFC.
