"Output": Initiates data transfer over the digital interface (Talk Only
mode). Single parameters, whole test set-ups or dynamic data can be
transferred. During data transfer the "Output" LED will light. When the
output of data has finished the Talk Only mode will be reset and the
"Output" LED will extinguish. The Talk Only data transfer can be inter-
rupted by pressing the "Output" key for a second time. If the key is
pressed for a third time a new output is initiated.
"Input": Puts the generator into Listen Only mode for input of set-up
parameter data over the digital interface. During input of data the "In-
put" LED will light. The Listen Only mode may be reset by pressing the
key for a second time.
"SRQ/ Addr.": Requests service from a controller. This function must
first be enabled by the controller. Otherwise, when the key is pressed
the IEEE bus address is displayed for about two seconds.
"Remote": An LED which will light when the generator is remotely con-
trolled via the digital interface. Local control may be regained by
pressing one of the parameter selection keys, providing the Local
Lock Out is not active.
Refer to section 4.2 and chapter 5 for further information about the
use of the Digital Interface.
