Optional Accessories for Multi-pumps Alternative Operation
When you use the multi-pump operation, pay attention to the following wirings.
1. Use a RJ45 cable (8 pin, Internet cable) without an adapter. Simply connect the master/slave
communication port. If there are more than two pumps, use RMKE-HUB01 to connect RJ45.
2. Use a RJ11 (6 pin) cable with an adapter to connect the master/ slave communication port.
3. You can also directly connect to SG+/SG- lock wire terminals without using accessories to form
multiple communication alternate operation systems.
