Transponder
The L--3 ProTec is a single box design which is easily installed into any existing
bridge layout. The compact design requires minimal clearance (refer to Figure 3--2
and Figure 3--3) and can be mounted in a trunion bracket or mounted flush using the
available flush--mount bracket. Install the transponder is as follows:

and Figure 3--3) and can be mounted in a trunion bracket or mounted flush using the
available flush--mount bracket. Install the transponder is as follows:
(1)
Mount the transponder in a position which provides easy access to the key-
board and display. If using the trunion bracket, the mount itself may be used to
mark the screw holes on the mounting surface. When locating the transponder,
consider that the IMO mandates that the AIS keyboard and display be easily
accessed from a navigable position on the bridge.

(2)
If used, Mount the transponder in the trunion utilizing the trunion knobs pro-
vided, otherwise mount transponder in flush mount bracket.

(3)
Locate and mount the terminal block or junction box in a position near the
transponder. The IEC cable provided with the unit is 100 inches (2.5 m) long
and the terminal block should be located to take this into account. Locate the
terminal block in a fashion which allows for easy access to the terminals for
making the connections to required input/output feeds.

Refer to Figure 3--4. Connect the transponder power cable to the power con-
nection on the Transponder and connect to the ships 12--24 Vdc power supply.
The “Red“ lead goes to positive and “Black“ to negative. Ensure proper ground
wire attachment to ships structure.

The other two leads can be used to connect to an external alarm system. This
alarm system can provide an audio and/or visual alarm in the event of an inter-
nal system malfunction, or if the AIS loses power or is turned off.

Lead data cables from Gyrocompass data output port and ship’s DGPS data
output port. To terminal block. If an interface adapter must be used to convert
either Gyro output and/or dGPS output to IEC (NMEA 0183) standard, the out-
put from the interfaces should be located as near as possible to the sending
unit (Gyro or dGPS) and the output cables led to the IEC terminal block.

Feed the IEC data cable pigtail to the terminal block.
(8)
Do not power up the unit at this time. The transponder should not be powered
up without the VHF antenna connected.
