Pulse Output
The meter provides two pulse outputs. Both pulse outputs are passive type.
Pulse output 1 is configurable. The pulse output can be set to generate pulses to represent total / import/export kWh or kVarh.
The pulse constant can be set to generate 1 pulse per: 0.001(default) /0.01/0.1/1kWh/kVarh.
Pulse width: 200/100/60ms
Pulse output 2 is non-configurable. It is fixed up with import kWh. The constant is 1000imp/kWh.

RS485 output for Modbus RTU
The meter provides a RS485 port for remote communication. Modbus RTU is the protocol applied. For Modbus RTU, the following RS485 communication parameters can be configured from the Set-up menu.
Baud rate: 1200, 2400, 4800, 9600
Parity: NONE/EVEN/ODD
Stop bits: 1 or 2
Modbus Address: 1 to 247
