3 Installation
Considerations
3.1 Mounting
The control unit is designed to be installed in a
standard 19-inch rack mount system and should be
mounted and operated in the normal horizontal
orientation.
Fixing holes of the standard pattern are provided on
the 1U front panel; these provide adequate support for
the unit.
The control unit is designed to be mounted remote
from the amplifier and the RF system.
When designing the installation, a space of approxi-
mately 100 mm should be allowed behind the rear
panel of the control unit for the disconnection of and
the bend radius of the interconnection cable.
3.2 RF Connections
Always disconnect the interconnection lead from the
control unit to the amplifier before installing or
removing any RF system components.
3.3 Cooling Considerations
The control unit is designed to operate in ambient
temperatures between 0 and +50 8C; it requires no
additional ventilation. Care should be taken when
choosing the location of the control unit, to avoid
external heat sources that may lead to the ambient
temperature exceeding the above limit.
3.4 Interface Connections
As there are many installation variations, the cabling
between the amplifier and control unit is not provided
as standard. Contact e2v technologies for details of
interface cable accessories.
For details of cable termination instructions including
cable type etc., see section 7.
4 Operation of the
Control Unit
The N6081 is used to control an amplifier from the
following product series:
N61xx
(e.g. N6132D, N6150D)
N63xx
(e.g. N6312, N6318D)
N64xx
(e.g. N6440)
4.1 Applying The Voltage Supply
The N6081 requires no external power supply as it is
powered by the amplifier via a dedicated line within the
control cabling.
Before connecting the control cabling, the operator
must be satisfied that:
*
Safety requirements are complied with (see the
safety notes at the front of this manual)
*
The amplifier is off.
Connect the control cabling from the amplifier to the
15-way D-type socket on the back of the N6081 and, if
it is safe to do so, apply power to the amplifier.
4.2 The Amplifier Search Process
As soon as power is supplied to the amplifier and the
control cabling is connected, the N6081 will initiate the
amplifier search process. This will be apparent as the
following message will be momentarily displayed on
the N6081 display (if the HPA is found quickly, this
message may not be seen):
The N6081 will now search through the 64 available
addresses at a Baud rate of 9600 until communication
is established. This process will continue until an
amplifier is found. When an amplifier is found, a
message will appear on the display, similar to the
following:
This message indicates that communication has been
established with the amplifier whose address is 40H.
This message will be displayed for 2 seconds. It should
be noted that if at any time communication is lost with
the amplifier, this process will be repeated.
The amplifier fan will be rotating at low speed and the
controller "OFF" LED will be lit.
