BRUEL & KJAER 1618 - Page 12

The following interface functions
are available on the Type 1617:
Acceptor Handshake (AH 1)
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 the
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
si nce 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.12 shows the connection pos-
sibilities with other Bruel & Kjcer in-
struments, including the cables re-
quired.
The Band Pass Filters can also be
employed as external filters for
B & K Sound Level Meters Type
2203 and Type 2209 , and for Vibra -
tion Meters Type 2510 and Type
2511 .
