1.6 Network setup

In addition to the entry of the IP address, Host name, Radar source, Chart source, and Sounder source must be entered to get various display modes and display combinations in the NETWORK SETUP menu.

1) Host Name: Type a name for own display unit to distinguish it from others in the network. The factory-default is shown in the above table. The name can contain figures.

2) Radar Source: Type the host name of the display unit from which the radar picture is received. This line is factory-set to RADAR for Model series display unit which comes with the scanner unit.

3) Chart Source: Type the host name of the display unit from which the chart data is received or which has chart card in its slot to use. A maximum of three units, excluding own display unit are preset on three lines.

4) Sounder Source: Factory-default is SOUNDER to connect the network sounder ETR-6/10N to the network. When the ETR-6/10N is not connected, blank this line so that the sounder symbol in the display selection window is disabled with a red X mark.

Subnet mask, Gateway address, and Offset port number are not used. Never change these values. (SUBNET MASK: 255.255.000.000; GATEWAY ADDRESS: 000.000.000.000; and OFFSET PORT NUMBER: 10000)

Radar source and sounder source are also selectable through the user accessible Select source menu. When two radars or more are connected in the network, either of them is selected through the Select source menu by the user. Note that at the moment, one netsounder can be used in the network. The Sounder option is for future-use.

Important!

The same radar source should be selected on the NavNet plotter display units. Never select different radar source on each plotter display unit if two radars and plotters are in the network. For example, in the network shown in the figure below, radar source must be selected to either M1943C or M1833C on both plotters.

Table 1.6 shows the example of setup menu setting for a network shown in Figure 1.10.

1.7 ARP Function

1.7 ARP Function

In the network shown in Figure 1.12, the radar sends following signals to the plotter. 1) Radar picture

2) Heading data from SC-60 or PG-1000 3) LL and speed data from GP-310B 4) ARP TTM data

Figure 1.12 Signals between radar and plotter

The radar picture includes Heading data so that the display in HU, NU, or CU mode is available on the plotter. TTM data is switched on and off through OUTPUT THROUGH NETWORK menu. A target is acquired and tracking target is erased from the plotter. Note that only one radar in the network can be quipped with ARP board. Table below summarizes controls of radar picture and ARP targets.

In the network shown in Figure 1.11, 1) with the radar source selection of example 4, a target can be acquired and a tracking target can be erased from all display units; 2) with example 1, M1833C cannot control ARP on the M1943C if M1833C displays own radar picture on the screen; and 3) with example 3, ARP target does not appear on the screen.

1.8 Connection of ETR

If the ETR receives the interfere from the echo sounder even when Interference Rejecter is turned on, the connection of the external KP is required as below. Drill a hole on the chassis of the ETR to pass through the cable.

How to make factory reset for IP address

To get factory default setting of IP address and Host name,

1. Put a jumper between J8 #1 and #2, and between J8 #7 and #8. 2. Turn on the ETR.

CR1 lights and then blinks when the reset is complete.
