I try to communicate between SLC MVI46-MCM (master) and Trio motion MC206X (slave) in modbus protol with RS422 4 wires.

When i connect 1 trio slave, it communicate correctly (read and write). With 2 or 3 slaves, i receive many corrupted character on the MVI. The read work correctly but the write does not work.

Does anybody have experience with this device ?

Thank for your help

Do you have 120 ohm termination resistors at each end of the network?  You do not want resistors at each device.
