The JP2 of i-7531 is used for adjusting terminal resistor on CAN Port 1, and the JP3 of i-7531 is used for adjusting terminal resistor on CAN Port 2. Before adjusting JP2 or JP3 of i-7531, user needs to open the cover of i-7531 first.
< 90 ~0.5 (AWG20) < 50 ~0.8 (AWG18) < 33 ~1.3 (AWG16) < 20 The recommended AC parameters of CAN bus line are 120 impedance and 5 ns/m specific line delay. i-7531 CAN Repeater User Manual (ver. 1.2, 2008/02/13) ------12...
For example, if users use baud 500K and one i-7531, the ideal total bus length will be “100 – 40 * 1 = 60 meters“. Specially, in baud 1M bps, add one i-7531 will cause the ideal total bus length to be less than 4 meters.
