A ---9
The OA 5000 supports many GPIB function subsets, as listed below. Some
of the listings describe subsets that the OA 5000 does not support.
H
SH1 (Source Handshake). The OA 5000 can transmit multi-line mes-
sages across the GPIB.
H
AH1 (Acceptor Handshake). The OA 5000 can receive multi-line mes-
sages across the GPIB.
H
T6 (Talker). The OA 5000 becomes a talker when its talk address is sent
with the ATN (Attention) line asserted. It ceases to be a talker when
another device’s talk address is sent with ATN asserted. The OA 5000
has no talk-only capability.
H
L4 (Listener). The OA 5000 becomes a listener when its listen address is
sent with the ATN (Attention) line asserted. The OA 5000 does not have
listen-only capability.
H
SRQ (Service Request). The OA 5000 asserts the SRQ (Service Re-
quest) line to notify the controller when it requires service.
H
RL1 (Remote/Local). The OA 5000 responds to both the GTL (Go To
Local) and LLO (Local Lock Out) interface messages.
H
PPO (Parallel Poll). The OA 5000 has no parallel poll capability. It does
not respond to the following interface messages: PPC, PPD, PPE, and
PPU. The OA 5000 does not send out a status message when the ATN
(Attention) and EOI (End of Instruction) lines are asserted simultaneous-
ly.
H
DCL (Device Clear). When acting as a listener, the OA 5000 responds to
the DCL (Device Clear) and SDC (Selected Device Clear) interface
messages.
H
DT (Device Trigger). The OA 5000 does not respond to the GET (Group
Execute Trigger) interface message.
H
C0 (Controller). The OA 5000 cannot control other devices.
H
E2 (Electrical). The OA 5000 uses tri-state buffers to provide optimal
high-speed data transfer.
