PL-8
User Guide AP5270 issue 3
Observe the local standards which may apply to the installation
regarding the grade of cable and installation methods.
To ensure operator safety ensure that any exposed metal face plates
and surfaces are correctly bonded to ground. Do not install the equipment
where it is subject to moisture, heat or vibration.
Connect this equipment to the Allen & Heath PL-Anet port only. Do
not connect it to Ethernet, DR-Link or other RJ45 ports.
When wiring to custom components and external equipment care
must be taken to ensure each part operates within its specified capability.
This work should be carried out by competent installation personnel only.
Before powering up the system make sure all the wiring is
inspected and continuity tested. This is important as wiring errors may
result in damage to the equipment.
PL-Anet
is the proprietary Allen & Heath system for daisy chaining remote
controllers. It is an RS485 serial connection that uses CAT5 STP cable to
communicate between devices over long distances. An RJ45 connector is
used. PL-Anet only works with Allen & Heath
PL
devices. The port provides
+20V DC to power the connected devices. The
iDR-8
port is shown here.
Number of devices
The maximum number of
PL
devices that can be
connected depends on their type and the distances involved. You can connect
up to 15x
PL-8
units on a single PL-Anet branch, and up to 23 if you are using
the optional
PL-9
PL-Anet hub. Fewer may be connected if long distances or
additional
PL
types are involved. It is important that you check the possibilities
first by referring to the PL Combinations Calculator spreadsheet available from
the Allen & Heath web site.
Description
the
PL-8
comes supplied with two PCB assemblies attached
to a brushed aluminium wall plate. This enables it to be mounted into a
standard single gang wall backing box. A UK, EU (European) or US
(American) size plate together with fixing screws is provided according to
which version has been ordered.
The top PCB houses the circuit which interfaces to the
iDR
PL-Anet control
network. Connection is made using two RJ45 type sockets, one to receive PL-
Anet, the other to pass it on to the next
PL
device in the chain. If this is the last
device in the chain then the terminator plug provided must be plugged in.
The lower PCB houses the screw terminal blocks which are used to wire to
switches, indicators, relays and other custom controls within the installation.
One block connects to up to four switches, the other provides up to four logic
outputs.
Note: PL-8 Units manufactured prior
to November 2004 were fitted with
5way terminal blocks with a single
ground terminal, rather than the
7way version used on later models
as described below. If you require
any more information on the earlier
models, please contact Allen &
Heath technical support.
