Here is a list of the basic interface functions and their subsets:
Function Subset designations
Service Request SR SR0,1
Whether or not an instrument is
allowed to request service from
the controller with the SRQ line)
Remote-Local RL RL1,...,2
(Switching capabilities between
manual (local) control and
programmable (remote) operation)
Parallel Poll PP PP0,...,2
Device Clear DC DC0,...,2
Device Trigger DT DT0,1
(Whether or not an instrument or
group of instruments can be triggered
or some action started upon receipt of
the group executive trigger (GET) message)
Source Handshake (Whether or not a device SH SH0,1
is allowed to generate the handshake
cycle fortransmitting data)
Acceptor Handshake AH AH0,1
(Whether or not a device is allowed
to generate the handshakecycle
for receiving data)
Talker T T0,...,1
(Capabilities for transmission of data)
Extended Talker (Like Talker, but TE TE0,...,8
using secondary addresses as well)
Listener (Capabilities for receipt of data) L L0,...,4
Extended Listener (Like Listener, but LE LE0,...,4
using secondary addresses as well)
The HM81 .. is equipped with the following functions:
Function Code Description
Source Handshake SH1 Full capability
Acceptor Handshake AH1 Full capability
Control function C0 Cannot function as Controller over other devices
Talker T5 Full capability
Listener L4 Full capability (except Listen-only mode)
Service Request SR1 Full capability

• BasicTalker
• Talk Only
• Serialpoll
• „Unaddressed if My Listen Address“ (prevents instrument from being a talker
and a listener at the same time)
