Transmission outputRS-485
Protocol: MODBUS
Baudrate: 2400, 4800, 9600, 19.2k, 38.4kbps

Up to two point outputs are available for pulse output and alarm output.
Either of transmission output and pulse output (alarm output) is to be selected (see type name system).
Pulse output is output asynchronously with the display update interval.
Note that a time difference may be generated between the indicated value and the pulse number.

5 Remote input specification

The measurement items of the main display can be changed by applying a voltage from outside (Display screen 1 or Display screen 2).
Apply a voltage of 80 to 264 VAC or 80 to 143 VDC to the external input terminal (for 0.5 seconds or more). Each time a voltage is applied, the next item is selected.
