Programming a Test of the IEEE 488 Facility
 There are many different programs and items of equipment for communicating over
the IEEE 488 interface. In the following example, the user must be familiar with the
IEEE 488 bus controller to be used.
 The following example commands can be used to check for correct operation of the
IEEE 488 interface.
Initialize the bus controller as follows:
 Set Address 1 as the talker listener address.
 Make sure that bus time-out periods are set sufficiently high (e.g., 5 seconds).
 Set the bus controller to send EOI with last byte and to expect EOI on last byte of
received data.
 Send interface clear (IEEE 488 command).
 Send "SOURCE:STATE OFF" (one space between STATE and OFF).
 Send "SOURCE:STATE?"
 Instruct device 1 to TALK and input the response string.
 The response string should be "OFF".
(1) If the above procedure is unsuccessful, check the continuity of the IEEE
488 cable.
(2) If faulty, replace the cable.
(3) If the continuity of the cable is correct, return the ADTS 405 to the repair
depot.
