RS 422 network, make sure that all the devices have unique address. Check the
communication settings at the individual recorders manually.

sure that Dip-switches are correctly set for the communication details.
If RS 485/ RS 422 is used for connecting recorders, then make sure that last node is less
than 1000 meters from the PC. Also make sure that STP cable is being used for RS 485
connections.

required to carefully check whether RS 232 cable is connected to proper communication
port of PC or not.
