PowerTALK 101
Foreword
The PowerTALK product family, available from w ww.cocoon-creations.com,is
a
modular
the monitoring and management of proprietary industrial equipment.
COCOON has recognised that there is legacy equipment in production today that
is robust, reliable and relatively inexpensive, however, such equipment often
comes with limited ability on-board for centralised monitoring and management.
The PowerTALK tool set provides the intelligence needed to connect such
equipment with modern IT networks enabling central control and management of
the device.
PowerTALK conforms to industry standards, for example:
ÿ Industry standard, routable, communication protocol: TCP/IP (The
international standard)
ÿ Industry standard connectivity: 10BASET Ethernet as default (others available)
ÿ Industry standard lower level protocols: RS-232, RS-485
ÿ No restriction to higher level protocols passed through
set of tools that enable engineers and process controllers to
centralise

Introduction
Brief description
PowerTALK 101
PowerTALK 101 is an
that are transmitted through a standard Ethernet port and onto the corporate or industrial network
/Intranet/Internet.
It simultaneously also does the inverse: TCP/IP packets that are addressed to PowerTALK 101’s
IP Address (user definable) is accepted by the device and repackaged into the original stream of
serial data and is sent to the appropriate serial port.
The distance between any two PowerTALK 101 devices is irrelevant, as long as the TCP/IP
packets do not time out in transit, and the user application can accept such delays introduced by
the carrier network route. Given effective communication links, one PowerTALK 101 may,
hypothetically, be on one side of the globe, while the other may be in the same office block.
Each PowerTALK 101 device has 2 serial ports that may both be connected to conventional serial
links / separate serial communication networks on site. In combination with other equipment
such as the PowerTALK 103 RS-485 converter, each serial port may further be expanded to
more serial devices.
Ethernet-to-Serial Converter
that packages serial data into TCP/IP packets
PC configuration tool PT.EXE & PT98.EXE
PowerTALK/DOS and PowerTALK 98 are supplied free of charge. This software is used to track
PowerTALK 101 connections, to functionally test the system, to configure Ethernet type
information, to configure serial ports and set up Ethernet connections remotely.
PowerTALK 98 and PowerTALK/DOS (PT.EXE) have the same configuration abilities, but
PowerTALK 98 has easier testing features. PowerTALK 98 makes use of the advantage of the
GUI interface of Windows while PowerTALK/DOS makes use of a command line interface.
PowerTALK 98 connects via the PC serial port, PT.EXE via the PC Ethernet port.
Information on this software can be found in the on-line help in both PowerTALK 98, and PT.EXE
v1.01 on the distribution disk. (Run PT.EXE –h). Also see complete options and examples on
page 28.
Year 2000
The PowerTALK tool set is Y2K compliant – third party software used to control devices may not
be and therefore it is recommended that tests are conducted by clients to ensure interoperability
on critical Y2K or subsequent dates.

PowerTALK 101
PowerTALK 101 overview
Feature overview
• PowerTALK 101 can transport any serial protocol over standard Ethernet networks using
standardised transmission methods
• PowerTALK 101 can be Installed at any point on an Ethernet network
• Communication parameters can be changed from any port: local, remote or networked
• PowerTALK 101 is delivered with a standard IP to which it always respond.
• PowerTALK 101 can be configured with a second IP to fit into your network scheme.
• Configuration parameters such as IP and baud rate are stored in non-volatile memory
• Any port can be moved, replaced or upgraded without disruption to the network
• Data is available anywhere on the network - across campus or across countries
• Supports full or half duplex connections
• Data can be addressed to one port or to all ports simultaneously, depending on the
configuration
• Individually configurable PowerTALK device passwords are implemented for network
access control
• Individual local serial port passwords fixed for local access
PowerTALK 101 re-establishes each logical connection upon restart after a network or power
failure. PowerTALK 101 controls remote equipment. PowerTALK 101 gives Ethernet sites total
system uniformity. Now you can manage connections between non-Ethernet equipment with the
ease of Ethernet.

PowerTALK 101
Functional overview of PowerTALK 101
PowerTALK 101 is a network protocol converter, one unit having at least a serial port and an
Ethernet port. All PowerTALK 101 models utilise the TCP/IP protocol suite for communication and
configuration.
PowerTALK 101 uses UDP broadcast packets to effectively combine a campus wide Ethernet
network into one virtual RS-232 multi-drop network. Each port on each PowerTALK 101 device is
assigned to a virtual
channel, and all other ports connected to this
packets will normally not be carried by routers and bridges, and can only be used on a single or
virtualsegment.
PowerTALK 101B additionally has UDP peer to peer routed packets for one-to-one
communication. PowerTALK 101C also adds TCP peer to peer connections, for one-to-one
communication over unreliable and changing links.
PowerTALK 101 / 101B / 101C Data UDP broadcast single virtual segment
PowerTALK 101 / 101B / 101C Configuration UDP peer to peer across router
PowerTALK 101B / 101C Data UDP peer to peer across router
PowerTALK 101C Data TCP peer to peer across router, advanced
channel
, and all data received on this port will be transmitted into this
channel
, will receive all data traffic. UDP broadcast

Dimensions
PowerTALK 101 maximum dimensions.
Above dimensions exclude the terminal rail at the back of the PowerTALK 101 box.
Rear DIN rail
The 35mm DIN rail is provided for convenience, to mount up to two PowerTALK 103 RS-485
converters or other third party rail mount equipment such as power supplies, etc.
Additional power supply outputs
An additional power supply unit for external equipment with mounting holes 90mm x 90mm may
be mounted inside or outside the box, using the 4mm diameter holes provided. Such power
supply may be obtained from third parties, or from COCOON. See pages 8, 17 and 21.
Face plate care & maintenance
14
PowerTALK 101
The front surface is of brushed stainless steel, and shows fingerprints easily on the textured
finish. To remove, use a cloth with alcohol or spirits. Take care not to allow the volatile fluid to
come into contact with the vinyl stickers on the surface of the front plate.
When wiping the front panel surface, wipe horizontally; in the same direction as the brush finish
texture for the best results.

Fuses & links
• One PC board mounted 5mmx20mm fuse, 1A rating, fast blow
This fuse is for PSU overload protection
• Between terminals X1:2 and X1:6, a fuse with 3A rating, slow blow
This fuse is for short circuit protection against possible short circuit inside the box
• Between terminals X1:1 and X1:5, a link terminal
A link is used to isolate the Neutral or Negative power supply if needed.
• Between terminals X1:3 and X1:7, a link terminal
A link is used to connect the signal ground to the chassis ground.
Battery replacement
The PowerTALK 101 unit has a built in battery for the purpose of keeping time when the power
supply is removed. The lithium battery is expected to last for at least 10 years.
It is easily replaced by opening the front cover. The battery location is shown on page 17,
indicated as “BAT”.
