PULSE Multi-analyzer System Type 3560-B/C/D/E – Installation and IDAe Hardware72
6.4 5/1-ch. Dyn-X Input/Output Controller Modules Types
7538, 7538-A, 3560-B-110, 3560-B-120
This module comes in two versions: Type 7538
with LEMO connectors on the input channels and
Type 7538-A with BNC connectors. Type 3560-B-
110 is equivalent to Type 7538, while Type 3560-B-
120 is equivalent to Type 7538-A. For input of sig-
nals in one range to 10 V
peak
(dynamic range
160 dB) over the frequency range to 25.6 kHz.
6.4.1 Common Features
Output 1
BNC connector (see Fig.7.5 on page 90) for output
of a high-quality sine tone in the frequency range
0.1 Hz to 25.6 kHz. The maximum output voltage is
5V
rms
delivered in one output range through a 24-
bit D/A converter. Output may be grounded or
floating, controlled by PULSE software.
Tacho
BNT connector (see Fig.7.3 on page 89) capable of
providing power for tacho probes. This is connected in parallel with Input 1.
Multi Frame Control and Synchronisation
This is used for switching the front-end on and off remotely so that pressing any power
button on any front-end will power up all front-ends.
This connector is also used for multiframe control via AES/EBU. Connect all the frames
together with 50 Ω termination
a
at both ends using standard 50 Ω cables of maximum length
100 m. 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.
a. A 50 Ω termination is built into these modules and is activated when First or Last Frame is set to Yes.
