*We recommend the SI-35 of Lineeye Co., Ltd., for the
RS485 converter on the PC side. (When using SI-35,
FP2-CB485 (for FP2-MCU), FP
Σ (COM3 and COM4) or
FP-e, the maximum number you can connect is 99. When
using with devices other than these, the maximum
number will be limited to 31.)
Up to
99
Eco-POWER METERs can be connected!
Installation is easy using a CT even
for the power lines of existing equipment
