INTRODUCTION
The Furuno interface unit IF-2300 receives digital data from 2 types of sensors or equipment and
transmits them to other equipment through 3 output ports. It handles any data format as well as
IEC 61162-1 sentences. One application is to receive speed data and either heading or depth data
and supply the data to radar series FR-21x5 or FR/FAR-28x5.
1 OPERATION
The IF-2300 does not need any user operation except for turning on or off the power switch. The
power switch can be a ship’s switchboard or a small dedicated switch. The unit can be left
energized at all times whether the associated equipment is in use or not.
2 FUNCTIONAL OVERVIEW
The IF-2300 receives any data written in sentence format of IEC 61162-1 edition 1 or NMEA 0183
Version 1.5/2.0 or others. Two Receive Data are mixed in the IF-2300 and the compound data is
outputted through three output ports. One example of applications is to feed LAT/LON and wind
data to one input port of the radar.

CIF
Input and output data are in CIF format (FURUNO format). One record of input data is limitted up
to 300 bytes. Any bytes over that amount are invalid. Further, a record containing receive error is
also invalid.
IEC 61162-1
Input and output data are in IEC 61162-1 format. The P sentence (special code) is input/output.
Input port 1 takes priority over input port 2 when the same data is input to both. Note however that
the P sentence has no priority.
Priority is given to the input data sentences below. The P sentence is output preferentially.
AAM, APA, APB, BOD, BWC, RMA, RMB, RMC, WPL, XTE, ZDA
RD1: Receive data from an SDME (speedlog) in sentence of VBW or VTG
RD 2: Receive data in sentence of either HDT or other data e.g. MTW, DPT, DBT
Note: Position data (ex. Lat/Lon from a GPS navigator) is supplied directly to the FR/FAR-28x5
or FR-21x5 series radars.
TD1-3: Transmit data. Connect this output to Channel 1 of Radar FR-21x5 or FR/FAR-28x5 Series
Transmission rate: 4800 bps, Data batch is transferred from the receive buffer to the transmit
buffer at intervals of 500 ms. P sentences go straight through the transmit
buffer.
Overflow: The IF-2300 has the data receiving buffer, the capacity of which is 1600
characters (equivalent to 20 sentences) at inputs of RD1 and RD2. CR4
lights when the data amount exceeds this limit.

3 MAINTENANCE
3.1 Regular check
Check all cables and ground monthly for tight connection.
3.2 Self-test
Start-up test
The following check is done automatically at each power-on.
ROM test: Checks the program area.
RAM test: Checks all memories.
Input data test: Checks the input data size.
LED Indicator
Error is warned with the state of LEDs, CR1 - 4.
LED No. State Condition
CR1 (Green) Blinks every second. Normal
CR2 (Red) ON ROM faulty
CR3 (Red) ON RAM faulty
CR4 (Red) ON Input buffer overflowing
Overflow: If data into RD1 and RD2 exceeds a total of 1600 characters (equivalent to 20
sentences), CR4 lights in red.

Test mode
The test mode checks the ROM (Read Only Memory) and RAM (Random Access Memory) for
proper input and output of data by means of a loopback circuit. The test mode is initiated by turning
on the #4 segment of DIP switch S1.
ROM test: Checks the program area.
RAM test: Checks all memories.
SIO test: CPU loopback test. See below:

Fuse replacement
If the IF-2300 does not work, suspect the blown fuse. The fuse is accessible when the cover is
removed. It protects the electrical circuitry against overvoltage or internal short circuit. Find the
cause of problem before replacing the fuse. Only the fuse of 0.5 A should be used.

4 INSTALLATION
CAUTION
Turn off the power at the ship’s mains switchboard before commencing the terminal
connection of any equipment units. Only qualified personnel should work inside the
equipment.
4.1 General considerations for placement
! Maximum cable length: The IF-2300 is configured in the current loops and signal cables,
locally arranged, should be less than 5 m approx. as far as possible.
! Avoid direct sunlight.
! Select a clean and well-ventilated location.
! Select a place where shock, vibration, and noise are minimal.
! Select a location where temperature and humidity are moderate and stable.
4.2 Mounting
The IF-2300 may be mounted on a tabletop, bulkhead or overhead. Keep it away from the
magnetic compass by the distance stated in the specifications section.
Fixing
.1 Remove the cover.
.2 Fix the unit with tapping screws (ø4 x 16 mm, supplied). For thin walls, use nuts and bolts (to
be locally procured) instead of tapping screws.
Power cable
.1 Make a hole in the rubber bush for power cable entry (right side of the unit).
.2 Pass the power cable through the cable entrance.
.3 Remove the sheath by 30 mm.
.4 Remove the insulation on the VH connector (supplied) by 3 mm.
.5 Slip heat shrink tube over the vinyl wires of the cable. Solder the wires.
.6 Heat the heat shrink tube on each of positive and negative lines.
.7 Connect the VH connector to power jack J1 at the power inlet compartment (bottom right).
IMPORTANT: Pin 1 is for the positive (+) line, Pin 2 is for the negative (-) line.

Signal cables
Cables are not supplied in the standard kit. Locally procure the cable TTYCS-1 (Japan
Standard Cable) or equivalent. Crimp-on lugs supplied are good for 1.25 sq cables.
.1 The interface box can accommodate maximum 2 input lines and 3 output lines. Open holes in
the rubber bushes at required ports. For each signal cable, do the same as below:
.2 Remove the outer sheath by 50 mm.
.3 Pass the signal cable through the entrance selected.
.4 Remove the inner sheath by 30 mm and the insulation of cores by 6 mm.
.5 Twist wire shield and pass it through a 25 mm tubing (local supply).
.6 Fit crimp-on lugs (supplied) to cores. Check the connection.
.7 Cover areas between the shield and the armor (if provided) with vinyl tape.
.8 Fasten wires by crimp-on lugs on the terminal strip. Refer to the interconnection diagram.
.9 Replace the cover.
.10 Fix the cable with cable clamps (local supply) outside the equipment.

Grounding
- Connect the ground wire (IV-1.25 sq) between the ground terminal and the ship’s ground bus,
to avoid interference and electrical shock.
