1) Equipment ID Setup Method

- set up by using three switches in the rear panel.

- there are total three switches and first switch (1) indicates third digit, second (2) and third (3) switch

indicate fourth digit of IP Address.

192 . 168 . XX. XXX

①

②

③

- Third digit of IP Address can be set to 0~14(E) by using number one switch. 15(F) is not used.

- fourth digit of IP Address can be set to 0~255(FF) by using number two and three switches and method is

as below.

Rotary

Value

Decimal

Number

2) Example of IP ADDRESS setup

- when setting with 192 . 168 . 10 . 100

Set the third digit ‘10’ to number 1 switch ‘A(10)’. Fourth digit ‘100’ is set to number one switch and number 2 switch is to ‘6’, and number 3 switch to 4 which is remainder. (64 )16 = (100)10 Switches are HEX Codes.

3) Caution

- when connecting one or more amps, caution not to overlap the IP address values.

When IP address are overlapped, monitoring and volume controls will not available from PC. However, volume control with amp volume is possible.
