Connecting the sensor to a RS485 Bus
The RS485 interface on the CS1000 is a two-wire interface and operates in
half-duplex mode.
The number of CS1000s per RS485 bus is limited to 26. Use letters A to Z to
address the HECOM bus address.
The length of the bus line and the size of the terminating resistor depend on
the quality of cable used.
Connect several CS1000s using the RS485 interfaces according to the
following illustration:
