CONTROL WITH REMOTE DISPLAY UNIT LOVATO MODEL EXCRDU1 EXCRDU1 4.1 Connection of the RS485 bus EXCRDU1 remote display unit can control up to 32 starters in contemporary at choice between variable speed drives VLB3 series and soft starters ADXL series, connected in RS485. TE. The terminals TA and TB of the RS485 port of the VLB3 have the polarity reversed compared to the terminals A and B of the remote display unit EXCRDU1. If the VLB3 is the last node of the RS485 network, is necessary to insert the bus terminating resistor (integrated into VLB) by setting in position ON the dip-switch R. Otherwise, you must leave the dip-switch R in position OFF. VLB Dip-switch R = terminating resistor 7
