Each SmartMotor has a 2 wire RS-232 port. This port meets IEEE standards with full +/- 12VDC potential on the transmit line. Proper serial ground signal referencing and shielding techniques should be used. Under no circumstances should the shield of a cable be used for the RS-232 ground reference. This could result in noise or corrupt data as well as ground loops that could damage the serial port chip set.
Each SmartMotor boots up default to the ECHO_OFF state. This means that nothing received is transmitted or echoed back out.This is important to remember in serial “daisy-chain” set-ups.
They also boot-up defaulted to base address zero meaning they will listen and respond to any incoming valid SmartMotor commands.
