Wiring the System
Terminology
Node : Any single piece of IEEE1394 connected apparatus
Bus : The network of interconnected IEE1394 nodes
Hop : Any single IEEE1394 interconnecting cable
Lonely : No other active nodes detected
Powering the Node
IMPORTANT: DO NOT power the Option using the drive's 24V.
The IEEE1394 bus requires a separate,floating 24Vdc (12-24Vdc) supply connected to the
Power Input Connector, terminal X42.
As a guide, each node may take up to 20mA at 24V from this supply. A node will draw more
current at lower supply voltages, for example, a node may draw up to 40mA using a 12V
supply.
Supply 24Vdc to one of the nodes on the bus. The 24Vdc is transferred to other nodes on the
bus via the IEEE1394 cable.
Pin 01 = 24V
Pin 02 = 0V
If you do power more than one node on the same bus (for instance, one supply in each of two
enclosures allowing for one of the enclosures to be isolated yet maintaining the bus), the
supplies must again be separate,floating supplies.
Connect the 24V supply to the X42 terminal block using twisted pair cable.
Connecting the Nodes
Use an IEEE 1394a cable to connect two nodes together. These cables are considered
electrically sensitive. In electrically noisy environments, FireWire messages may be corrupted.
If this occurs, the system will automatically recover by restarting the communications. This
process is called a Bus Reset and can take up to 0.5 seconds to complete. During this time data
will not be transferred by the bus.
To avoid Bus Resets, keep electrically noisy and sensitive cables apart. Pay particular attention
to screening and earthing of motor cables. Where necessary, sensitive cables should cross noisy
cables at 90° to minimise capacitive coupling.
(The occurrence and frequency of Bus Resets can be monitored from the keypad).
The quality of RF earthing is important when using FireWire systems. In noisy environments, it
is recommended that each drive front plate is strapped to an adjacent drive using a copper braid,
to ensure a low impedance path for RF signals.
If some drives are mounted remotely, it is recommended that the FireWire cable between the
drives is fitted with a ferrite RF absorption clamp (SSD Part Number : DJ467799).
We can supply the following recommended cables:
SSD Part Number Cable Length
CM469189U002 0.2m
CM469189U003 0.28m
CM469189U010 1m
CM469189U045 4.5m
CM469189U100 10m
If using 10m cables, note that an
additional limitation applies: the cable
length limit between the two most distant
nodes on the network is 72m. 10m cables
should be used sparingly, and short (1m)
cables should be used wherever possible
to ensure this limit is not exceeded. See
"Extenders" below.

6
8903/FA Firewire IEEE 1394a Communications Interface
Each port is interchangeable – any message transmitted by the node exits all three ports. Any
message received on one port is repeated on the other two ports.
Nodes can be connected in a Daisy Chain or a Tree configuration but loops are not allowed.
The maximum number of hops between the most distant nodes on the network is 16, so for 17
or more nodes a Tree is essential. The maximum number of nodes is 63. Refer to Figure 6 on
next page.
Note:
The network power draw is approximately 20mA per node at 24V, approximately 40mA
at 12V. Note that 63 nodes at 24V (20mA per) is 1.26A total. The power system has
thermally self-resetting fuses for 1.5A. So, at 12V it is not possible to wire for more than
37 nodes reliably.

Loops like this are NOT allowed
Tree Configuration
Extenders
If any hop needs to be longer than 10m, then an extender is required to repeat the bus over
CAT5 cable or optical fibre. There are commercially available units such as:
www.fwdepot.com … FW2UTP-01 1x IEEE1394a port, 1xRJ45 CAT5 port
FW2UTP-02A 1x IEEE1394a port, 2xRJ45 CAT5 port
FW2UTP-02B 1x IEEE1394a port, 2xRJ45 CAT5 port
Any 2 of the above can be used with a CAT5 crossover cable of up to 100m.
www.newnex.com … FireNex-MX (TM) 2xIEEE1394a ports, 1x optical duplex LC port
Two of the above can be used with 100m of LC to LC ,62.5125um, multi-mode optical cable.

Initial Set-up
Configuring the 890 Drive
All drives in the system MUST be fitted with a FireWire Option that is wired correctly.
The FireWire Option is plug-and-play, requires no setting-up, and can be used in the following
ways:
1. The Drive may exchange data with other Drives using Network inputs and outputs
configured using DSE.
2. DSE :use FireWire to connect DSE to all drives in the system.
3. Peer-To-Peer : use FireWire to link drive parameters.
4. Virtual Axis : use FireWire to broadcast synchronised information to all drives on the
system (e.g. a shaftless printing application).
You can use the diagnostics provided in the FIREWIRE block to see your system at work.
