Refer to the interconnection diagram for details of pins on the terminal boards. Turn off the DCU before making connections.

Note 1: The DCU and DRU are connected to each other with the supplied IEEE1394 (sometimes called FireWire*) cable on which two plugs are factory-fitted at both ends. These plugs look like the same but these are different; one has latches and the other does not. These are labeled

“DCU” and “DRU,” so connect the cable accordingly

.

*FireWire is a registered trademark of the Apple Corporation. It was originally developed as a very fast external bus technology that supports data transfer rates of up to 400Mbps.

Note 2: Attach cable band (supplied) to each cable to be connected to the DCU and record sensor name/equipment name on each cable band.

2.2.2 Working inside the unit

Snap/wire assembly for keeping door of DCU open

A snap/wire assembly which keeps the door of the DCU open while working inside the DCU is provided. Use it to keep the door open and prevent deformation of the door when it is opened.

Attach one snap to the hole on the door and the other snap to the hole to the right of the battery handle. Note that it is not necessary to detach the assembly before closing the door.

This procedure is necessary only when the unit is mounted on the deck.

Attach snap to hole.

Lead-fitting tool

Radar, MIC, VHF, etc. are connected to the terminals and connectors in the DCU. The terminal board has WAGO connectors for leads of up to 2.5 mm 2 or AWG 14 wires. Use the lead-fitting tool, attached inside the DCU, to fix wires to WAGO connectors, as shown in the illustration below.

Lead fittting tool

How to use lead-fitting tool

1) Strip sheath by 8-10 mm.

3) Tug on wires to confirm that they are securely

inserted.

2) Use lead-fitting tool to open terminal and then insert wire.

Ground the armor of the IEEE1394 cable by the cable clamp at the DCU. Fabricate the cable as follows.

1. Confirm the label “DCU” at the end of the cable end. (Fabricate the cable at the DCU side.)

2. Use a box cutter to cut and remove the heat-shrink tube and remove the vinyl sheath approx.

8 cm from the end of the cable.

2.3 Data Recording Unit (connecting IEEE1394 cable)

The DRU is connected to the DCU connector with a non-halogen IEEE1394 cable, 20 m or 30 m with IEEE1394 connectors factory-fitted at both ends. The connectors are labeled “DCU” and

“DRU,” respectively; do not confuse the connectors.

Additionally, observe the following handling considerations:

•

Do not cut the cable.

•

If welding of cable gland or cabling support is necessary, weld BEFORE running cable.

•

Take care not to damage shield of cable.

•

The connector which is to be attached to the DCU must be protected from rain. If necessary, run the cable through conduit or the like.

Connection at DRU

DRU end

DRU end of the cable is delivered with a waterproof coating. DO NOT remove this coating until it is time to connect cable to DRU. There is no notch to prevent the cable from being pulled out on the DRU side of the cable.

Take great care not to damage the cable when removing the waterproof coating.

There is no coating on the

DCU end of the cable.

DCU end

Connecting to DRU

Slide cap nut, teflon washer and rubber bushing onto the cable in that order.

30

Grease inside and outside of rubber bushing with supplied fluid compound. This allows for the rubber bushing/cable and rubber bushing/DRU connections to slide easily. It is important not to forget to do this process.

A

Coat threads "A" with fluid compound to prevent the scew component from burn.

First, connect the cable connector to the DRU. Do not apply the connector oil compund.

Push the cable in towards the DRU and affix the teflon washer and rubber bushing. (Not pushing the cable can result in the fastening notch not connecting properly, and is a common cause of a poor quality connection)

31

Coat surface of teflon washer and with the connecting part of the cable with supplied silicone sealant.

Thread

Gap: Approx. 2.6 mm

DO NOT OVERTIGHTEN

Thread screw OR

How to tighten cap nut

Tighten DRU cap nut until it stops turning. (The DRU edge must be in contact with inside side edge of the cap nut). Confirm at this time that approx. one thread of the cap nut remains visible.

Gap: Approx. 2.6 mm

Gap between cap nut and DRU

Coat the area around the cable connection, and the cap nut, with silicone sealaent for waterproofing.

32

A

- Mounting base "A" to be supplied

by shipyard.

- Mount DRU on compass deck.

- Choose location which affords

easy retreival.

- Locate well away from other

machinery, etc.

- It is preferable to bundle as much excess cable as possible

below decks.

- DO NOT cut cable even

if it is too long.

- Loop cable (min. 30cm loop, leave as much extra cable as possible),

and affix near the DRU (do not attach to the handle).

- Affix the cable to deck securely at intervals using convex

hooks , clamps, etc so that it cannot be moved

(The curvature radius must be greater than 15cm).

.

To keep the curvature wrap around the handle.

Fit rocker pins.

33

Connection at DCU

Connect cable to the DRU connector (J8) in the DCU and secure it with a cable tie. Using vinyl tape, tape from tip of connector to about 8 cm.

Secure cable to post with cable tie. Tape from connector tip to about 8 cm with vinyl tape.

Optional Kit

The optional kit is provided for the cable ran (IEEE1394 Cable) passing through the deck.

Maximum two additional junction boxes may be installed. An additional junction box has connections for 1 serial channel (IEC 61162-1, CH3 only), 64 digital channels, and 16 analog channels. See the figure below for general wiring.

When installing additional junction boxes, set junction box no. (2 and 3) with DIP SW S5. If the junction box no. of additional junction boxes is left as “1”, data will not be output from the junction box. For setting procedure, see page 50.

Note: The serial channels in the Junction Box IF-8530 can receive the maximum of 82 characters in a sentence, consisting of a maximum of 79 characters between the starting delimiter "$" or “!” and the terminating delimiter <CR>, <LF> as defined by NMEA0183/IEC61162.

2.7.1 IEC 61162-1 serial data

12 channels are provided to receive IEC 61162-1 serial data, six in the DCU and six in the JB.

Receivable are all IEC 61162 sentences and binary data, but at least ZDA is necessary for stamping date and time.

2.7.3 Non-IEC 61162 signal

1) Analog

4 to 20 mA, 0 to 10 V and –10 to +10 V signals (max. 16 channels) can be connected to the

ANALOG terminals in the JB. Input voltage (current) range is set by DIP switches in the junction box.

Voltage signal

The voltage between two input terminals is 0 to +10V or –10 to +10 V

.

Current signal

For 4 to 20 mA current signal set jumper between I and V as shown below.

2) Digital (Voltage and Contact-closure)

The terminals for digital input in the JB connect voltage and contact-closure signals. Range of input voltage is 10 to 32 V. The system sends 24 VDC to ”floating contact.”

The figures below show the digital interface circuit for voltage and contact-closure signals respectively.

Interfacing of contact-closure signal

Note: Jumpers are fitted at factory between A and 24 terminals for CH1 to CH32 in order to connect contact-closure signal. To connect a voltage signal to CH1 to CH32, remove jumper by using two openers attached inside the junction box. To connect a contact-closure signal to CH33 to CH64, short between A and 24 terminals by using a jumper wire (local supply).

2.8 VHF Interface Unit

Two VHF audio signals may be connected to the terminal board in the DCU. IMO requires one

VHF audio to be recorded. A dual twisted, balanced cable carries the following signals:

+: 24 VDC (+)

A: Audio signal line, balanced, 0 dBm

B: Audio signal line, balanced, 0 dBm

-: 24 VDC (-)

The VHF interface unit mixes VHF transmitting and receiving signals for the VDR. When the VHF outputs the mixed signal, this unit is not required.
