VAR8 / Variants - Installation Guide
1.1 Installation Requirements
• The VAR8 unit.
• A 19-inch standard rack wired and configured with V400 amplifier mainframes, and wiring for
power supply, signal monitoring, CAN bus, and RS232 and RS485 cabling as appropriate.
• A small flat-bladed screwdriver.
• Large pozidrive screwdriver.
• Cable termination tools - cutters/strippers etc. to suit cable type.
1.1.1 Cabling Requirements
The following cabling is recommended within the equipment rack. For pinout refer to Figure 1 (page
5), and for cabling connector refer to Section “2 Connections” (page 12).
1. DC power supply cabling:
Standard cable rated for 3A.
Recommended type: BELDEN 8205LSHF.
2. Audio input:
Twisted pairs, individually screened.
Recommended type: BELDEN 8451 LSHF.
The rack and field cabling should be as described in the diagram shown in Figure 3.
3. A/B audio outputs on Interface Expansion Board (EXP8):
Twisted pairs, individually screened.
Recommended type: BELDEN 8451 LSHF.
The rack and field cabling should be as described in the diagram shown in Figure 3.
4. Audio and data network cabling (on VAR8 with Network Interface Card):
Twisted pairs with overall foil screen.
Recommended type: FS cables 2407 POFYH.
The Upstream side of the network connection is isolated RS485. To maximise the benefits of this,
the rack and field cabling should be as described in the diagram shown in Figure 2.
5. Other cabling:
Overall screened.
Recommended type: BELDEN LS0H.
The rack and field cabling should be as described in the diagram shown in Figure 3.
6. Audio outputs on RJ45 (see signals and pinout in Table 1, page 13):
Cabling: overall foil screened.
Recommended type: CAT5 STP or FTP LS0H
The rack and field cabling should be as described in the diagram shown in Figure 3.
The use of screened cables where specified is necessary for EMC compliance. Also for
EMC compliance, rack and field cabling should be according to the specified diagram.

1.2 Recommended Installation Procedure
Please read and observe the “Safety and Precautions” section on page 20 of this
manual.
1. If installing a VAR8 with a Network Interface Card, note that the Network Interface Card is
configured, by default, for network operation using 3 audio network channels. If stand-alone
operation or 1 or 2 channel only network operation is required, set the links on the Router board
as described in Section “1.3 Link Settings for Stand-Alone, 1 or 2 Channel Only Network
Operation” on page 11.
2. Mount the VAR8 into a 19-inch standard equipment rack.

Ensure that there is at least 1U of ventilated space between the unit and any source
of heat (e.g. V400 amplifier mainframes).
3. Connect the rack and field cabling for control ports, audio inputs, audio outputs, signal monitoring,
CAN bus, RS232, and RS485, as appropriate.
Wiring to each VAR8 connector should be according to the diagram shown in Figure
3on page 8for EMC compliance.

The following drawings indicate the position of the connectors on the rear panel. Note that upper
control port, A/B output, and network interface connectors may not be present, depending on the
VAR8 variant being installed.
Figure 1 on page 5shows details of each connector. Section “2 Connections” on page 12
describes the signals.

1.3 Link Settings for Stand-Alone, 1 or 2 Channel Only Network
Operation
• This procedure is required when the VAR8 is fitted with an ANIC8 Network Interface
Card, and stand-alone operation, or 1 or 2 network channel only operation is required
instead of the default 3 channel network operation.
• If any difficult is found in accessing the links, then please refer to Application Solutions
Limited.

2. Configure the links as follow:
1. Remove the unit’s lid by undoing the
screws located on the top of the unit.

5 Safety and
Precautions
5.5 Lithium Battery
Danger of explosion if battery is
incorrectly replaced. Replace only
with the same or equivalent type.
Dispose of battery carefully to

5.3 EMC
EMC compliance is dependent on this unit
being wired in accordance with these
installation instructions.
All electronics assemblies must be
properly packed in ESD protective
packing for transport, to prevent
physical and ESD damage. Use of
non-ESD protective packing for
return for repair or service will
automatically invalidate the
warranty.
5.4 Electrical Safety
Always replace blown fuses with
the correct type and rating.
The filler material used for packing
for return for repair must be
antistatic or static dissipative, as
this may come into contact with
exposed connectors, wiring, or
PCB assemblies. The use of non-
conductive filler material may
cause damage to the electronic
assemblies reducing their
operational life, or even destroying
them, and it will automatically
invalidate the warranty.
Ensure adequately rated cables
are used for power supply.
