1 Product introduction
CT103 is a repeater with RF Uplink & RS485 downlink. It’s a bridge between the Concentrator and
Meter to transfer the meter’s data. The Repeater comes with an RF module that connects the Repeater
via the RS485 interface. The communication Repeater can provide a path for forwarding weak signals,
so that the Concentrator can reliably communicate with the Repeater. The communication is not
encrypted. The Repeater only implements transmit through function.
As a part of Kaifa repeater solution, the CT103 provides RS485 port and SPD detection port and
integrated Repeating functions as described in section 1.3.
