Base Address

For the IP address 192.168.a.b:
a is set by bits 7..6, with a range of 0 ~ 3 and a default value of 0.
b is set by bits 5..0, with a DIP switch range of 0 ~ 32 and a default value of 100.
The actual value of b is calculated as (DIP switch bits 5..0) × 4 to support 2-bit expansion.
The default IP address is 192.168.0.100, corresponding to the DIP switch setting 00011001 (bit7..bit0).
After changing the DIP switch settings, power must be turned off and on again for the changes to take effect.

IP Address and Channel

The IP address can be configured using the base address and the DIP switch value.
If the DIP switch value of the GPCon2 module is x, the IP address of the GPCon2 module becomes 100 + x.
The channel numbering is defined as indicated on the GPCon2 module.

For example, when the base address is 192.168.0.100 and the GPCon2 DIP switch value is 1, the resulting IP address becomes 192.168.0.101.
In this case, the upper port (ch0) corresponds to channel = 0, and the lower port corresponds to channel = 1.
