ELECTRICAL CONNECTIONS

3.1.1
RS-485 STANDARD CONNECTIONS
The Control Basic Plus pump implements ANSI/TIA/EIA-485 standard communications, also known as RS-485. Some
manufacturers swap the "A" and "B" connections, which may cause confusion, but this is not the case with the pump.
Keep this in mind when connecting the pump to MODBUS appliances from other companies.
Some manufacturers swap the A and B connections" which may cause confusion, in this device B is the T+R+ and the A
is the T-R-, the following pinout correspond to the female connector (the connector installed on the Pool Basic
Double/Control Basic/Optima Plus)
The recommended wiring for a MODBUS-RTU communication is based on a linear structure, active bus with termination
at both ends. It is possible to couple and uncouple devices during operation without affecting other devices. The wire
shall be twisted and shielded according to EN 50170.
The values of transmission rate supported by the device allows maximum cable length of 1,200 m without repeaters, or
up to 10 km using repeaters, when installed according to the standard.
For the balanced pairs used in an RS-485 system, a Characteristic Impedance with a value higher than 100 Ohms is
preferred, especially for 19200 and higher baud rates.
