All modules requiring network or power connection, excluding the Control Panels and Printers, use a standard 6 way connector, supplied with the modules. The pin assignment is as follows:

NETWORK/POWER connector

1 Network Data B 2 Network Data A 3 Not used 4 Not used 5 Power Supply negative 6 Power Supply positive

An earth stud is provided adjacent to this connector.

The Control Panels use a way terminal block with the terminal numbers marked. See Control Panel technical information for connection details.

2



Network wiring and termination

The network connections of the respective modules must form a daisy chain with the two ends terminated. A shielded, twisted pair data cable capable of supporting communications at 1.25 Mb/s must be used (see “Interconnection Cables” at the end of this section)

Network terminators are included in all modules with a network connection and these may be enabled or disabled via a jumper link. Prior to installation determine which modules require the terminators to be enabled (i.e. modules at either end of a network) and set these accordingly (link fitted) The default setting is disabled (link not fitted).

Excluding the Control Panel and Printer, the network termination link is located inside the modules adjacent to the ‘POWER/NETWORK’ connector. Refer to the specific module technical information for details.

The Control Panel network termination link is accessible via the rear access plate.

Module Number

All modules connected to the network have a set of module number links which must be set prior to installation of the modules. The default setting is Module Number 1 for all modules.

If a second module of the same type is connected to the same network (including networks divided by routers) then it's module number should be set to Module Number 2. Likewise a third module of the same type connected to the same network should be set to Module Number 3.

Modules that are logically linked through the network must have the same Module Number setting. The logical links are as follows:- VHF DSC Modem and VHF Transceiver Interface MF/HF DSC Modem and MF/HF Transceiver Interface Telex Codec and Telex PC Interface

Examples: VHF DSC Modem Module Number 1 linked with VHF Transceiver Interface Module Number 1 VHF DSC Modem Module Number 2 linked with VHF Transceiver Interface Module Number 2

See individual module information for location and setting of module number links.

Other system connections Refer to the relevant module technical information for details.

3



Working with Multi Connection System connectors and terminal blocks

Three types of connectors are used in the DSC2 system: * BNC connectors for MF, HF and VHF aerial connections * Sub-D connectors (DB9, DB15, DB25, etc.) * Multi System Connectors (MSC). These connectors have an orange color.

The Multi System Connectors (MSC) are used for NETWORK/POWER, AUDIO/CONTROL and GPS/Alarm input/output connections.

Multi-stranded wires from 0.08 mm2 up to 2.50 mm2 can be inserted in and extracted from the MSC connector or terminal block by using an operating lever or a simple screwdriver of the appropriate size. If more than one wire has to go into one connection point, care should be taken that the wires are properly twisted together before inserting them into the connector. If this is not possible, a suitable insulated crimp terminal must be used to bond the wires together before insertion into the terminal block or connector.

4



Fitting Watch Receivers and Telex Codec modules These modules are always connected to their appropriate DSC Modem. They are supplied with

ribbon cable & connectors for connection to the DSC Modem. The connection system requires that the Watch Receiver and the Telex Codec modules are

mounted in the same orientation directly below or above the DSC Modem. Fit the ribbon cables with their connectors after mounting these modules in the correct way.

Connections to transceivers

The VHF & MF/HF DSC Modem modules use a standard 6 way connector (supplied with the modules). The pin assignment is as follows: Pin Function Characteristics Nominal Level 1 Audio in 600 Ohm transformer coupled input 0 dBm 2 Audio in 600 Ohm transformer coupled input 3 Audio out 600 Ohm transformer coupled output 0 dBm 4 Audio out 600 Ohm transformer coupled output 5 PTT isolated, volt free, normally open contact 6 PTT isolated, volt free, normally open contact The output is adjustable from zero to +10 dBm for the VHF & MF/HF DSC Modem. The input can be attenuated from 0 to 100% by means of an internal adjustment for MF/HF DSC Modem only. All adjustments are accessible once the main endplate has been removed. The connections between the DSC Modem, the Transceiver Interface Module and the transceiver are covered in the relevant Transceiver Interface technical information.

Interconnection Cables The DSC2 system has 3 main types of interconnections: Power Interconnection, Network Interconnection and Audio interconnection. A shielded, twisted pair cable must be used for each of the 3 types of interconnection (separate cables for each type). For connections of less than 1 meter, the cables must comply at least with following:

conductor size: 22 AWG or 0.35 mm2 stranding: 19/.006 (imperial) or 19/0.15 (metric)

For connections up to 10 meters, the cables must comply with at least following:


For connections up to 50 meters, the cables must comply with at least following:

DSC2 SYSTEM CONFIGURATION

Introduction The configuration process of the DSC2 system sets up all the Control Panels in the system to ensure correct operation with all available DSC2 modules. The configuration operation must be carried out by the installation engineer when the system is installed or when any major changes are required. The configuration options of the DSC2 are protected by a password to prevent unauthorized access. The configuration process specifies which modules are available for use within the DSC2 system and sets up the operating characteristics of the system. Any changes made to the configuration settings will be sent to all the Control Panels that are present on the network. Whilst in the ‘CONFIGURATION’ menu, it will not be possible to send any type of DSC call or respond to any new calls. The configuration menu is entered by selecting the ‘CONFIGURATION’ option in the DSC2 menu. Access to the configuration menu is password protected. Once the correct configuration password has been entered a warning message is displayed indicating that it will not be possible to send any distress alerts or call or see any new calls whilst in the configuration mode.

If ‘Yes’ is selected, the ‘CONFIGURATION’ menu will be entered.

HANDSET TRANSCEIVER

Introduction The DSC2-007.01 is used to automatically control a Sailor RT2048 VHF transceiver. It provides fully automated channel control and audio switching functions.

Dimensions Length: 95 mm (not including mating connectors) Width: 109 mm Height: 32 mm Weight 300 g

Indicators & Fuses PWR On when main 5V internal supply is OK. NET Off for correct operation. FUSE Type F, 20x5 cartridge, 0.5 A, located within the DSC2-007

Power The DSC2-007.01 is powered from the transceiver it is connected to and needs approximately 100 mA from the 13 Vdc provided by the RT2048.

Important

The transceiver interface case is electrically connected to the 0V line of the transceiver.

To conform with power supply isolation requirements the transceiver must be powered from a floating supply.

Network Module name: DscVTRXn (where n is 1 to 4) Number of modules allowed: 4 Module number: selectable via link setting, jumper LK2 Network termination: selectable via link setting, jumper LK1

Use with a DSC2-002.00 VHF DSC Modem The ‘unit number’ of the VHF DSC2-002 Modem and DSC2-007 Transceiver Interface must be the same and may not conflict with other VHF DSC Modems or Transceiver Interfaces on the network.

Override The audio switching between the RT2048 and the DSC modem is automatically controlled by the interface provided the Override connection is linked to the Override GND connection. If this link is broken, the audio switching is forced to connect the RT2048 handset with the RT2048.

DSC LED output A LED may be connected between the DSC LED outputs to indicate when the interface module has switched the transceiver to DSC mode. This output is current-limited to 10 mA.

Audio in/out The audio input and output are balanced, transformer isolated connections. A 0 dBm audio input level from the VHF DSC2-002 Modem should produce the required deviation in the transceiver. The output level on the VHF DSC Modem may need adjusting to obtain the correct deviation of the transceiver.

The Network Router and the single fault principle. The single fault principle means that no single fault should cause a complete GMDSS system to fail. IMO states in SOLAS-GMDSS, Chapter IV, Regulation 15, paragraphs 6 & 7 that availability of the functional requirements specified in regulation 4 shall be ensured by using such methods as duplication of equipment, shore-based maintenance or at-sea electronic maintenance. For Sea-areas A3 and A4, a combination of at least two of these methods must be used.

The Primary and the Duplication installation are separated by a DSC2-009.00 GMDSS Network Router. This allows any single fault to occur in this DSC2 combination without taking the whole system down. In normal operations, this Router is fully transparent towards operation of the system



Properties of the Router All modules are connected to the network through a Network Transformer. This means that whatever happens inside a module only results in the breakdown of that module. But should a Network Transformer or the network cabling become short-circuited, it would take the whole network down if there was no Router present. If there was no Network Router present, a single fault would cause the entire system to fail. Internal Block Diagram

NETWORK a NETWORK b

DSC2-009.00 ROUTER

TransferProcessor b

A DSC2-009.00 GMDSS Network Router has two major identical internal building blocks each consisting of a Transfer Processor and a Network Interface. The Network Interfaces and the Transfer Processors electronics are provided with power from the system that supplies the modules connected to Network a. The Network Interfaces each consist of electronics and a Network Transformer for connection to the network. Each building block is based on Lonworks® technology from Echelon. The Network Interfaces are based on the TPT/XF-1250 Twisted pair Transceiver and the Transfer Processor is based on the RTR-10 Router Core Module. These components have each an MTBF of more than 12,000,000 hours at 55°C (worst case). As shown in the block diagram, the Router is connected to each network through a separate Network Transformer. This means, that whatever happens inside the module of the Router, both networks remain fully operational, but both sides will not be able to see each other anymore. Hence there is a DSC2-001 Control Panel located on each side of the Router, so that both sides still can be operated, even with a broken down Router. A short circuit of one of the Network Transformers is seen as a “single fault”. That is one of the reasons for having two separate Network Transformers inside the Router.



Major single faults that may occur while the two sides will remain fully functional, but operate separately, are:

* Loss of power to the Router. * Breakdown of the electronics of the Router. Single fault that may occur within the Router which will still have either the Primary or Duplication section operational:

* Short circuit of one Network Transformer. Single fault that may occur outside the Router, on either the Primary or Duplication side, which will still have the non-affected section fully operational:

* Any fault. The Router provides the necessary safety to ensure availability of equipment based on the principle that no single fault should cause the complete system (Primary and Duplication) to fail.

Data Format Protocol Data is in serial asynchronous ASCII form. The first bit is a start bit and is followed by data bits, least-significant-bit first as illustrated below. The following parameters are used: Baud rate 4800, Data bits 8 (d7 = 0), Parity None, Stop bits One. D0 Dl D2 D3 D4 D5 D6 D7 STOP BIT DATA BITS START BIT Characters All transmitted data shall be interpreted as ASCII characters. The most significant bit of the 8-bit character shall always be transmitted as zero (d7 = 0). Reserved Characters The reserved character set consists of those ASCII characters shown in Clause 6.1 (Table 1) of IEC1162 . These characters are used for specific formatting purposes, such as sentence and field delimiting, and may not be used in data fields. Valid Characters The valid character set consists of all printable ASCII characters (HEX 20 to HEX 7E) except those defined as reserved characters. Undefined Characters ASCII values not specified as either "reserved characters" or "valid characters" are excluded and may not be transmitted at any time. Character Symbols When individual characters are used in this standard to define units of measurement, to indicate the type of data field, type of sentence, etc. they will be interpreted according to the character symbol table in Clause 6.1 (Table 3) of IEC1162. Fields A field consists of a string of valid characters, or no characters (NULL field), located between two appropriate delimiter characters. Address Field An address field is the first field in a sentence and follows the “$” delimiter, it serves to define the sentence. Characters within the address field are limited to digits and upper case letters Data Fields Data Fields in approved sentences follow a “,” delimiter and contain valid characters in accordance with the formats illustrated in Clause 6.2 (Table 6) of IEC1162. Data fields in proprietary sentences contain only valid characters but are not defined by this standard. Because of the presence of variable data fields and NULL fields, specific data fields may only be located within a sentence by observing the field delimiters “,”. Therefore it is essential for the LISTENER to locate fields by counting delimiters rather than counting the total number of characters received from the start of the sentence.

PICSSxx - DSC Module Status These sentences are used as a transport for DSC status messages in the DSC2 network system. All modules in the DSC2 system output status messages onto the network every five seconds or whenever the content of the message changes. When the DSC2-014 receives a status message, it translates and outputs this message as an Sxx NMEA sentence. This allows closed loop systems to be developed and ensures correct operation of the system.
