  • Page 22: Bus Specifications

    8. BUS SPECIFICATIONS < Features > This unit employs a bus system incorporating the 'e-Bus' (bi-directional packet communications) concept, and is used for control of independent and system operation. The Master unit controls all the bus sysytem. The bus system provides for mutual recognition, with control commands and status information being sent and received between units, thus allowing linked operation of multiple units.
  • Page 24 Remote Bus Connection ID Numbers Each unit is identified by a set ID number. Each ID number is set by the user. The unit with ID=1 is as the Master. ID=1 is also used for stand-alone (single-unit) operation. If there are multiple units with the same ID number, connection error occurs and the error code is displayed, The Master must be at the top in the bus connection.
