The 4125 Series Dual-frequency Side Scan Sonar System includes a number of ETHERNET devices
connected on a common local area network (LAN), and each of these devices has a factory set TCP/IP
address which under normal circumstances does not require changing.
However, should any of these devices be replaced, or if upgrades are later installed, it may be required
that the TCP/IP addresses be reconfigured. In addition, any computer that is to be connected to the 4125-
P Portable Topside Processor must have its IP address set to 192.9.0.nnn, where nnn is any integer from
1 to 100, except for the following reserved addresses:
x 192.9.0.225
x 192.9.0.101
The factory IP address setting of the wired ETHERNET connection for the laptop computer included with
the 4125-P Portable Topside Processor is 192.9.0.99, and for the wireless ETHERNET connection, the
factory setting is 192.9.0.100. For a list of the topside processor ETHERNET devices and their TCP/IP
addresses, refer to Table 3-2, and for the tow vehicle, Table 3-3.

Assembling the 4125 Tow Vehicle
To assemble the tow 4125 Tow Vehicle, refer to Figure 3-2 and the following instructions:
1. Insert the four tail fins into the tail fin slots in the tail cone.
2. While holding the tow vehicle vertically with the nose down, insert the tail cone with the installed
