WS-H1002 Eight expansion module

Functional characteristics:

Before the module is connected to the multiplex bus, the host should power off and set up the address dialing switch on the module.

Do not set multiple eight-zone extension modules or compatible multiplexing extension modules to the same address, otherwise it will lead to multiplexing bus failure.

The module's available address bits are 1 to 253, address bits 0, 254, and 255 are not available.

The MBUS bus has no polarity.
