2. Overview
The 2300 Multiplexer and Data Telemetry Assembly is the power, digital telemetry, and device interface
hub of the 2300 vehicle. The system consists of 3 parts: Rack Mounted Topside, Digital Telemetry
conversion, and the Device Multiplexer within the 2300 Vehicle. The Rack Mounted Topside consists of
the multiplexer's data distribution hub, high voltage power supply, and the EdgeTech data display and
control computer. The tow cable terminates at the 2300 Multiplexer pressure housing. The Multiplexer
powers and provides ethernet and serial data connections to several external devices, including the
EdgeTech 2205 Sonar System and Magnetometer sensor (optional). The Multiplexer interface is
designed to have generic power/trigger/serial connectors to allow for a variety of device connections
where only the external interface cable is changed.
The 2300 vehicle is built to support not only multiple Sidescan/Bathymetric and Sub-Bottom
configurations, but the addition of a Multiplexer allows for easier integration of additional sensors such as
a Magnetometer, Beacon, or Environmental Sensor Assembly … to name a few. Unlike previous 2000 or
2200/TVD systems, the Sonar Processing bottle does not directly connect to any of the external sensors.
All sensor and sonar data connects to the multiplexer where it is converted to an IP (Internet Protocol)
packet and transmitted to the Starmux IV Topside.
When data is received at the Starmux IV Topside, the information is made available on the
network interface or on the various Serial Ports. For clarity, the term “Serial Port” refer to the serial
interfacea on the Starmux IV. The serial ports on the Topside Computer are labeled as “COM Ports”.
Again, note that all sensor data is available on the Starmux IV Serial Ports but to merge this data with
Discover or to serially monitor the data with a PC Utility (such as TerraTerm), a serial connection must
be made from the Starmux IV to the PC. With the exception of Serial Port #1, all ports are wired as DCE
(Data Communications Equipment) which allows the user to connect these serial ports to a PC using a
STRAIGHT cable. Serial Port #1 is wired as DTE (Data Terminal Equipment) so it emulates a PC COM
port for interfacing with a NEMA device such as a GPS.

3. 2300 System Block Diagram
The general system block diagram, drawing 0021988, depicts the complete 2300 interconnection system
of which the Multiplexer is the data telemetry and power distribution portion. Any individual sensors are
discussed in their commercial manuals.
• Page 1 of 0021988 depicts the Topside Computer and Dual Monitors (if applicable) and the
Starmux IV Multiplexer Chassis Assembly (red dashed box).
• Page 2 of 0021988 depicts the 2300 and 2205 Subsea Pressure housings and the sensors
(optional) this system can be interface.
4. Network Configuration
Internal system devices are configured by making changes in the web-accessible configuration pages. No
device-specific software was written to configure the units. Configuration pages are accessed by clicking
on a saved bookmark (Figure 4-1) or by typing their IP address (listed in Table 4-1) in the address field of
a web browser. Bookmarks are located in the Internet Explorer Favorites Tab or the Favorites Dropdown
Menu. EdgeTech computers are set up with populated Internet Explorer favorites and are configured to
save the last window display.
• If the favorites become corrupted, they can be imported from a saved backup found at
C:\EdgeTech\Multiplexer Configuration\Internet Explorer\boomarks.html.
• The most critical window to keep open is the Subsea Device Power Relays (WebRelay). This
display will depict what device is powered and what is the internal temperature of the Multiplexer
bottle.
Do NOT use Microsoft Edge as the Network Browser. It does not
work well with the various devices’ HTML web pages. Only use
Internet Explorer.

5. Operations - General
1. At start-up, turn ON the Starmux IV Topside and verify that the current, at 350vdc, is nominally 0.20
amps. This is the current draw of the housekeeping electronics.
2. Open Internet Explorer once the topside computer is operational. All web-accessible device
configuration pages should have an Internet Explorer Tab set up and can also be found under the
Favorites’ Menu or accessed by typing their IP address in (see Table 4-1). If the Subsea components
are not active or fully booted, a specific tab may show “No Device Found” or “Address Not
Accessible.” In these instances, click the refresh icon in Internet Explorer to reload the web page.
3. To activate any of the Subsea hardware, the components must be turned ON via the Power Supply
Relay (WebRelay) web interface (Figure 5-1). From here, you can activate each desired device.
Refer to the various device Appendices for the serial Diagnostic displays which will show which
device is Transmitting (TX) data from the Subsea and Receiving (RX) data at the Topside.

4. The 2205 electronics are controlled via TWO selections on the WebRelay Screen.
• The 2205 electronics and Tri-Frequency/Bathymetric arrays are controlled through the 2205
SONAR (J8) connection.
• If Sub-Bottom is required, the section labeled “2205 SB AMPS (J8)” must also be activated.
NOTE: When the 2205 electronics are powered, a timing sequence is initiated where the SB capacitor
bank begins a trickle charge process for approximately 45 seconds before being fully charged and brought
On-Line. At this point, the “2205 SB AMPS (J8)” WebRelay indicator will show “ON”. If the SB
amplifiers are not required, the WebRelay can be turned OFF until they are needed.
5. The remaining devices can be activated as needed by simply turning the devices “ON.” If an OPTION
connector is not used, it is recommended that power NOT be applied to this bulkhead.
When the system is power cycled, all relays will return to their default OFF state. This is a
precautionary configuration where the user must choose the systems to activate and to have the
ability to isolate any malfunctioning component.
6. Topside System Assembly
6.1 EdgeTech STARMUX IV Telemetry Multiplexer Topside
This chassis provides the Telemetry Interface for all data communications as well as providing the user
with convenient bi-directional serial and trigger interfaces. The front panel is shown in Figure 6-1 and the
rear panel in Figure 6-2. As noted previously … the StarMux IV is the dry side of the 2300’s telemetry
system. To access a sensor’s serial data, a cable must be run from the Starmux IV rear panel serial
connection to a computer (such as the optional Topside PC). The Starmux IV Serial Interfaces are NOT
recognized by the Windows OS and cannot be changed using any Windows utility.

2300 System Technical and User’s Guide
Document : 0022174 Rev B Page 10
Figure 6-1: Topside Multiplexer, Front View
The rear panel provides 4 network interface ports that are internally connected through a network switch.
All network devices share the same base network address of 192.9.0.xxx. The 6 serial interfaces are
mapped to the 6 serial ports within the Subsea multiplexer and configured as DCE devices (with the
exception of Serial Port #1 being DTE). Four BNC connectors are provided to connect FSK and/or
TTL/CMOS digital triggers to the system. Only the FSK input is presently used in the 2300 to provide a
Topside Trigger to the Tracking Beacon. When the Digital I/O feature is active, there is one additional
input and two additional output triggers. The tow cable's coax connection is made at the connector
denoted below.
