The RS485-ISO adapter provides electrically isolated conversion from RS-232 on the main 7W2 connector to RS-485. The adapter comes standard with a 10-foot power cable and two parallel 4 pin Molex RS-485 connectors.
RS-485 provides improved noise immunity over cable lengths of up to 1,000 ft (305m). It also allows you to operate a network of up to 120 SmartMotor servos in parallel, rather than daisy-chaining the communications from one motor to the next.
The adapter draws power and ground from the SmartMotor main connector (pins 2 and 5). It does require the use of the main connector G-Sync line (pin 1) for readwrite control of the 485 transceiver.
The RS485-ISO communications adapter can be ordered with or without the power cable (no cable P/N: RS485ISO-NOCBL).
