BRUEL & KJAER 1618 - Page 11

The following interface functions
are available on the Type 1 61 7:
Acceptor Handshake (AH1)
Listener Function (L2)
Remote Local Function (RL2)
Parallel Poll Function (PP2)
Busy is indicated via NRFD (not
ready for data) hold method when
the Band Pass Filter is feeding a Re-
corder.
A Listen Address switch on t.
rear panel allows the instrument
Listener address to be set for use
with remote digital control. There is
a PPR Selector for setting the Paral-
lel Poll Response, used here to re-
port whether there has been an
overload in the Input Amplifier
since the previous interrogation.
This is used to assess the validity of
the levels measured in the filter
bands.
Connection to the digital bus is
made via the 25-lead plug on the
rear panel of the instrument.
Operation with other
instruments
Fig.1 2 shows the connection pos-
sibilities with other Bruel & in-
struments, including the cables re-
quired.
The Band Pass Filters can also be
employed as external filters for
B & K Sound Level Meters and Vi-
bration Meters.
