RS485 Setup
The IN400 data port is an RS485 serial data port. Twisted pair cabling should be used when connecting
RS485 devices, such as CAT3, CAT5, CAT5e or CAT6 UTP cabling. RS485 data networks should be wired
in a ‘daisy chain’ confi guration with a maximum of 32 devices in the chain. The IN400 is not terminated
so may be inserted anywhere in the data network. If the IN400 is being used at the end of a chain,
a 120ohm (characteristic impedance of UTP) terminating resistor should be connected between
the + and - connections.
The IN400 has built in failsafe bias circuitry so there are no need for external biasing resistors.
The maximum length of the chain is 500m.
Global Mode
When the IN400 is in global mode, changes to the volume and tone affect all the sources.
When not in global mode, changes to the volume and tone affects the selected source.
