good day,
It may depend on many things:
-the hardware that you use for communication(fibre or copper);
-the distance between the two panel(lenght of the cable);
-type of the communication cards(232...);
-may be the card itself;
-and may be also the config of the panel.

need more precision to help you.
best regards,
