The MPI programming cables are available at VIPA in different variants. The cables pro-
vide a RS232 res. USB plug for the PC and a bus enabled RS485 plug for the CPU. Due
to the RS485 connection you may plug the MPI programming cables directly to an
already plugged plug on the RS485 jack. Every bus participant identifies itself at the bus
with an unique address, in the course of the address 0 is reserved for programming
devices.
A cable has to be terminated with its surge impedance. For this you switch on the termi-
nating resistor at the first and the last participant of a network or a segment. Please make
sure that the participants with the activated terminating resistors are always power sup-
plied. Otherwise it may cause interferences on the bus.
