ATTENTION – READ THIS FIRST!
All personnel involved with the installation, operation, or maintenance of the equipment described in this
manual should read and understand the warnings and cautions provided below.
CAUTION! This equipment contains devices that are extremely sensitive

HARDWARE VARIATIONS AND COMPATIBILITY
The Starmux IV contains both standard and proprietary hardware. At times, EdgeTech may change the
standard components due to their availability or performance improvements. Although the component
manufacturers and their models and styles may change from unit to unit, replacement parts will generally
be interchangeable.
EdgeTech will make every effort to see that replacement components are interchangeable and use the
same software drivers (if applicable). At times, however, direct replacements may not exist. When this
happens, EdgeTech will provide the necessary drivers with the replacement part, if applicable.
EdgeTech may also change certain hardware per customer requirements. Therefore, portions of this
manual, such as parts lists and test features, are subject to change. These sections should be used for
reference only. When changes are made that affect system operation, they will be explicitly noted. Some
options and features may not be active in the customer's unit at the delivery time. Upgrades will be made
available when these features are implemented.
Contact EDGETECH CUSTOMER SERVICE with any questions relating to compatibility.

RETURNED MATERIAL AUTHORIZATION
Before returning any equipment to EdgeTech, a Returned Material Authorization (RMA) number must be
obtained. The RMA will help us identify your equipment when it arrives at our receiving dock and track
the equipment while it is at our facility. The material should be shipped to the address provided in the
EDGETECH CUSTOMER SERVICE section. Please refer to the RMA number on all documents and
correspondences as well.
All returned materials must be shipped prepaid. Freight collect shipments will not be accepted. EdgeTech
will pay freight charges on materials going back to the customer after being evaluated and/or repaired.
CAUTION! If your product is a portable topside, never attempt to ship it
in the 6U case alone. Although rugged, these cases are not intended to
be used as shipping containers, and the delicate internal components
could be damaged if used in this manner.
The following steps apply only to the material being returned from outside the continental United States.
Follow them carefully to prevent delays and additional costs.
1. All shipments must be accompanied by three copies of your proforma invoice, showing the
material's value and the reason for its return. If the reason is for repair, it must be clearly stated
to move through customs quickly and without duties being charged. Whenever possible, please
send copies of the original export shipping documents with the consignment.
2. If the equipment's value is over $1000, the following Shipper's oath must be sent with the invoice.
This oath can be typed on the invoice or a separate letterhead:
"I, ______________________________, declare that the articles herein specified are the
growth, produce, or manufacture of the United States; that they were exported from the
United States from the port of _____________________, on or about _______________;
that they are returned without having been advanced in value or improved in condition
by any process of manufacture or any other means; and that no drawback, or allowance
has been paid or admitted hereof."
Signed ______________________________

ix
3. If there is more than one item per consignment, a packing list must accompany the shipment. It
is acceptable to combine the proforma invoice and packing list as long as each carton's contents
are clearly numbered and identified on the invoice.
4. Small items can be shipped prepaid directly to EdgeTech by FedEx, DHL, UPS, Airborne, etc.
5. If the equipment is the property of EdgeTech (formerly EG&G Marine Instruments Division),
please insure for full value.
6. Fax one invoice, packing list, and a copy of the airway bill to EdgeTech upon shipment.

1.0: OVERVIEW
The Starmux IV provides power to 2300, 4200, 4205, 2050-DSS, 2000-DSS, or 2000-TVD Towfish while
acting as a digital link between the towfish and a topside computer with EdgeTech's Discover application
installed on it. The Starmux IV features a modern digital current display, four status indicator lights, and
connectors for supporting survey devices and triggers. It can be bought independently, combined with an
EdgeTech Computer in a rugged 6U case, or as a component of an EdgeTech towfish system. The Starmux
IV has replaced the Starmux III digital link.
CAUTION! Never attempt to attach the Starmux IV to the 4125i Series Towfish
or any other model that it is not designed for. The voltages involved could
damage and destroy all equipment. Please contact EDGETECH CUSTOMER SERVICE
if you are unsure if your towfish is compatible with the Starmux IV.
This manual provides: Starmux IV physical and electrical specifications, mechanical drawings, control,
indicator light, and connection descriptions, setup, activation and maintenance instructions, and provides
troubleshooting tips. It should be used in combination with EdgeTech Discover Software and EdgeTech
Hardware Manuals to support your towfish system. Download links for the latest manual for this product
and others can be found in the SUPPORT RESOURCE CENTER WEBPAGE and under the Downloads Tab of each
product webpage on the EDGETECH WEBSITE.

3.0: SETUP AND ACTIVATION
The setup of a particular system depends upon the configuration. However, the following general
guidelines may be used for most systems. Further instructions can be found in the product's hardware
and Discover software manuals.
3.1 Unpacking and Inspecting
Carefully unpack the Starmux IV and check the packing list to ensure that all items are present. If any items
are missing, report it to EDGETECH CUSTOMER SERVICE. Likewise, if any items have been damaged during
shipping, do not install them. Instead, contact EdgeTech for further instructions.
Save the original packaging that the system came with, as these containers can and should be used when
the system is not used for extended periods of time.
3.2 Installing the Starmux IV
The Starmux IV in any configuration should be located and set up in a dry, sheltered environment that is
protected from weather and water spray. All configurations require an environment where the
temperature is consistently between 0–45°C (32–113°F) and humidity no greater than 90%. Avoid areas
of direct sunlight, especially in tropical environments, as heat buildup could damage the equipment, and
glare could hinder the user's ability to see the LCD and status indicators.
The Starmux IV in any configuration should be physically located in an area that provides unimpeded
access and is within the physical and electrical limits of the network, device, and tow cabling and power
source it is attached to. Please avoid severe bends, particularly with the tow cable. The Starmux IV should
also be located in a place that allows users to communicate directly with the deck crew handling the
towfish.
If mounting a Starmux IV on a 19-inch rack, ensure that there is ample room behind the rack for connecting
the cables. Support the rack's components using appropriate mounting brackets and secure the front
panels using standard 19-inch rack front panel mounting hardware. A drawing with dimensions and
weights can be found in the MECHANICAL DRAWINGS section of this manual.
