1. COMMUNICATION FUNCTIONS
1.1 General
• This instrument provides a communication function through RS-232 interface, which
allows data transmit to or receive from the host computer and other devices.
• The communication system is comprised of a master station and slave stations. One slave
station (this instrument) can be connected to one master station. It is also possible to adapt
the instrument to the environment of RS-485 interface using RS-232 RS-485
converter. In this case, up to 31 of slave station (present instrument) can be connected per
master station.
• Because the master station can communicate with only one slave station at a time, the
destination can be identified by the "Station No" set for each slave station.
• In order that the master station and the slave station can communicate, the format of the
transmit/receive data must coincide. In this instrument, the format of the communication data
is determined by the MODBUS protocol.
