3 INSTALLATION PROCEDURES
Basic Installation Flow:
CHECK INSTALLATION PARTS
(Section “3.1. Installation Parts” on page 15)
- Check that all parts for installation have been received.
This should include: cables, connectors, brackets etc.

(Section “3.2. Transducer” on page 15)
- Install the Transducer
- Install the Transducer Cable Gland
LOCATE DRX / GPS / SENSORS
(Section “3.3. Locating the DRX System” on page 15)
- Run cables to DRX location
MOUNT THE DRX
(Section “3.4. Mounting the DRX” on page 16)
CONNECTING THE DRX
(Section “3.5. Connecting the DRX” on page 18)

3.2. TRANSDUCER
The DRX supports multiple transducer types and can be setup to operate in a variety of
configurations. Typical setup will be multibeam wideband mode with:
»
WMB160
»
WMB80
Detailed specification and mounting methods for supported transducers is described in
the WASSP Transducer Installation Manual.
Transducer selection is described in
“5.2.4. Data Setup Tab” on page 39.
3.3. LOCATING THE DRX SYSTEM
The DRX is a highly sensitive receiver which is capable of discerning signals of less than
one microvolt. In order to get the highest performance out of the DRX system keep
the transducer, transducer cable and the DRX far away from sources of electrical and
acoustic noise. AC/DC inverters and DC/DC converters are particularly noisy and even if
not used to power the system, should be kept as far away as possible.
The DRX will need to be located with access to all required sensors. This needs to
include transducer cable, GPS, motion sensor and LAN connections. Serial cables from
sensors should be run direct to DRX with no splitters or interfaces boxes.
When selecting a mounting location, keep the following points in mind to maintain
optimal performance:
»
Maintain ambient temperature in the vicinity of the DRX within operating
specifications. Operating in temperatures outside of specification will result in
reduced operating lifetime or direct failure due to overheating:
• The area needs to be well ventilated in order to avoid local ambient increase
from self heating.
• Keep out of direct sunlight. Exposure to sunlight will result in direct solar gain
