SYSTEM COMPONENTS
Each TIF plugs into the main rack and is wired to the back panel co-axial connector pairs A to
H for onward connection to the velocity path transducers and W to Z for connection to
ultrasonic depth transducers at the time of installation. Fig 5 shows the rear panel connectors.
TIF 1 in card position 7 is connected to A and B and to W.
TIF 2 in card position 6 is connected to to C and D and X etc.
Note that the upstream velocity transducers must be connected to the upper row of A to H
and the downstream ones to the lower row.
The standard rear panel allows connections to 32 velocity paths (64 transducers) and 16
ultrasonic depths via “multi-drop” wiring of the smart transducers.
The velocity transducers may be allocated to up to 4 water channels without any restriction
other than the total number and cable lengths. Ultrasonic depth transducers are limited to 4
per channel via multi-drop. See Section 2.4.
Fig 5 Rear panel connections
The top row of coaxial connectors are for the upstream transducers, the bottom row for the
downstream ones.
Paths may be connected individually, for example, path 1 to A, 2 to B etc, or multi-dropped via
star junction boxes. For example, paths 1 to 4 connected to A etc.
Ultrasonic depths may be connected individually to W,X,Y,Z or multi-dropped via star boxes.
For BCD and analogue connections, see Section 2.3.3.2
