CHAPTER 6
Controller and Input/Output Modules

The AES/EBU protocol contains both clock and sync. signals as well as power control. See
“AES/EBU and Types 7536, 7537, 7538, 7539 and 7540” on page 16.
A circular LED around the Multiframe Control BNC socket indicates measurement status
(red: digital error; green: normal operation; flashing yellow: synch. signal; flashing red/
green: program download).
Aux. I/O
See section 7.1.
LAN
The LAN RJ-45 connector is used to connect the front-end to LAN systems based on RJ-45
cables. The protocol complies with IEEE 802.3 10 base T.
RS–232
See section 7.2.
Cable Lock
Threaded hole for attaching LAN Cable Holder UA-1617.
6.6.2 Types 7540, 3560-B-130
Input 1 to 5
7-pin LEMO connectors (see Fig.7.6 on page 90) for use with Brüel & Kjær microphones.
Input may be grounded or floating, controlled by PULSE software. LEMO to BNC adaptor
cables allow the connection of CCLD and DeltaTron
®
transducers.
For each channel, a circular LED surrounding each connector indicates the status of the
channel (activated: green; overload: red).
6.6.3 Types 7540-A, 3560-B-140
Input 1 to 5
BNC connectors (see Fig.7.4 on page 89) for direct connection of a voltage signal or for
connection of a CCLD transducer, for example, DeltaTron
®
accelerometers or microphone
preamplifiers. Input may be grounded or floating, controlled by PULSE software. All inputs
support IEEE 1451.4 capable transducers with TEDS.
For each channel, a circular LED surrounding each connector indicates the status of the
channel (activated: green; overload: red).
