Setting up the SDC 8000 system
52
̈
Connect the black RJ 45 plug of the system cable to the DATA OUT
socket
ƹ of the central unit.
̈
Connect the grey RJ 45 plug of the system cable to the DIGITAL BUS IN
socket of the analog output unit.
Daisy-chaining SDC 8000 AO analog output units
To daisy-chain SDC 8000 AO analog output units:
̈
Connect the DIGITAL BUS OUT socket of the first SDC 8000 AO to the
DIGITAL BUS IN socket of the second SDC 8000 AO, and so on.
Note!
You can connect up to four daisy-chained SDC 8000 AO analog output
units to the central unit.
Connecting external equipment to the SDC 8000 AO’s phoenix connector
The SDC 8000 AO is fitted with a voltage-free contact (phoenix connector)
which turns external equipment (e.g. a recording unit) on and off. When a
console is active, the contact is closed and when no console is active, the
contact is open.
The phoenix connector is numbered from left to right as shown in the
illustration on the left.
If you switch AC loads such as e.g. an electronic relay, the contacts 1 and 3
will be opened or short-circuited. Therefore, make sure that the following
limitations are not exceeded!
Maximum load current (continuous) = 1 A
Maximum load voltage = 60 V
On-resistance = 0.5
Ω
If you connect DC sources such as e.g. a relay coil, make sure that the
following limitations are not exceeded!
Maximum load current (continuous) = 1.8 A
Maximum load voltage = 60 V
On-resistance = 0.15
