If Upload is not success, it shown message as “No response from Recorder, connection fails”.
If this is the case, please check the RS 232 cable connections at both the recorder and PC. Also
make sure that green communication LED available for proper firm connection at back RS 232
port available at recorder back side.
If still communication is not established between the recorder & PC, then once again check Node
address at the recorder. If more than one recorder is connected in RS 485/ RS 422 network, make
sure that all the devices have unique address. Check the communication settings at the individual
recorders manually.
If the converter SNA 10A is used for converting RS 485/ RS 422 to RS 232, then make 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.
In some computers, COM 1 and COM 2 have been used for other devices. So it is required to
carefully check whether RS 232 cable is connected to proper communication port of PC or not.
