2.3 Settings for Two Network Sounders
2.3.1 Two ETR-30N network sounders
When installing two ETR-30N set the HOST NAME control to “0” for the No. 1 ETR-30N and
“1” for the No. 2 ETR-30 N. Turn the ETR-30N off and on again after setting the HOST
NAME control to register settings. When connecting NET KP, the ETR-30N having the
lowest IP address outputs the KP and other ETR-30N receives it. The ETR-30N having high
output power and low frequency should be set as the “Master” (HOST NAME control setting
“0”).
1. Set tap settings of the No. 1 and No. 2 ETR-30N as in paragraph 2.2.1.
2. Following the procedure in paragraph 2.2.2, confirm that the sounder source for the No.1
ETR-30N is “SOUNDER.” (HOST NAME control is set to “0.”)
3. Set up the No. 1 ETR-30 as shown in paragraph 2.2.3.
4. Set the HOST NAME control of the No. 2 ETR-30N to “1” and then turn on the power.

display unit as below.
