Options and Upgrades
4.15.2 Upgrade
Procedure
New SeaBat 8101 systems can be ordered from the factory with Option 046 in-
stalled. Existing sonar processors must be returned to RESON for installation of
this upgrade.
4.16 Option 047, Upgrade to SeaBat 8101S
This option allows the operator to switch between two different SeaBat 8101 op-
erating modes. These modes can be bathymetry or forward looking sonar (FLS)
such as the SeaBat 8102, or dual bathymetry using different beam geometries.
When an 8101 system is operating in the FLS mode, the sonar head transmits
and receives through the hydrophone array. Once an 8101 system has been up-
graded with option 047, it is referred to as an "S" version.
The upgrade process requires changes to the sonar head electronics and firm-
ware changes to the sonar processor. Both units must be returned to RESON for
the installation of this upgrade.
4.17 Option 049, Increase Sonar Head Depth Rating
The standard SeaBat 8101 system is designed with an aluminum sonar head
with a depth rating of 120 meters. This material and depth rating is ideal for over-
the-side installations on surface vessels. For those customers who work at
deeper depths with ROV or UUV installations, Option 049 provides increased
depth capability and a choice of sonar head material.
An aluminum head can be upgraded to a maximum depth rating of 1500 meters
(this requires the installation of an ER projector). For depths greater than 1500
meters, an upgrade to a titanium head is required.
A titanium head can be upgraded to a maximum depth rating of 3000 meters (this
requires the installation of an oil-filled ER projector).
Contact RESON for additional details on the particular upgrade applicable to a
customer's existing system.
4.18 Option 051, 24 VDC Power Supply for 81-P Processor
A standard SeaBat 81-P sonar processor uses auto-switching power supplies
configured for 90 to 260 VAC. Option 051 provides the ability to use a DC power
source such as two, or more, 12 VDC batteries on a small survey vessel. With
this option installed, both AC power supply modules in the processor are re-
placed with two DC-to-DC converters which will function with an input voltage
range of 18 to 72 VDC. At a nominal 24 DCV, the system requires a maximum of
240 watts. The sonar processor must be returned to RESON for the installation
of this upgrade.
