In the basic parameter setting mode, by setting the correct meter address,
communication baud rate and parity (Acuvim-CL/DL/EL/KL only), we can
engage in normal communication. The connection mode by setting the voltage,
current connection mode, the voltage transformation ratio PT1, PT2, the voltage
transformation ratio CT1, CT2 in order to achieve accurate measurement of the basic
amount. Please refer to the specific setting
"Acuvim-L User's Manual"
.
Communication
The meter has a standard RS485 communication port when the meter type is
Acuvim-CL/DL/EL/KL. The meter supports dual communication which means the
RS485 serial communication can be used together withother RS-485 in extend
module when the Acuvim-CL/DL/EL selected.
Serial communication terminals are A, B, S (14, 15, 16). A is differential , B is
differential signal – and S is shield. Up to 32 devices can be connectedon a RS485
bus. The overall length of the bus cannot exceed 1200m (4000ft). When multiple
meters are connected serially on the same RS485 bus, each meter shall have a
different device address. Enter basic parameter setting page to set the device
address. This address can be any integer between 1 and 247.
Baud rate can be selected from one of the six values: 1200, 2400, 4800, 9600, 19200
and 38400 bps. Parity needs to set one of the followings: Odd, Even, None1 (stop bit 1),
None2 (stop bit 2).
I/O Options (if equipped)
Two types of IO modules with different IO combinations are available.
IO parameters can be set or viewed either from the meter front or through
communication using utility software. Please refer to Acuvim-L user's manual for
operation details.
Digital Input (DI)
DI is a dry point, no external power supply. DI can be used as pulse counter, to
monitor switch status or to monitor sequence of events.
