1) Please check the device address under COMMS/IM64 in P54x relay(it should not be 00. Need to assign proper local & remote address .
Example.If your local device is 1A & remote should be 2A
2) Please check whether you are using proper cable (FO/RJ) requirement as per our manual Please check the clock source
as per your requirement (Internal or external)_Menu under PROT COMMS/IM64)The Clock Source should be set to “Internal” at all system ends, where they are connected by direct optical fiber,as the P54x at each end has to supply the clock.
The Clock Source should be set to External at all system ends, where the ends are connected by multiplexer equipment which is receiving a master clock signal from the multiplexer network. It is important that there is a single master clock source on the multiplexer network and that the multiplexer equipment at each end is synchronized to this clock.
Note:
This setting is not applicable if IEEE C37.94 mode selected
3) Please check the COMM Mode under COMMS/IM64 .IEEE C37.94 mode is normally selected if the Multiplexer accepts direct fiber inputs
For a direct fiber link between relays, and where the MUX connection is in electrical format (G.703 or V.35 or X.21), the Standard’ message format needs to be set.Note : For a setting change to take effect, rebooting of the relay will be required. The Comm Mode setting applies to both channels.
4) Please set the Baud rate , Comm Delay Tol ,GPS sys,(if applicable ) and other parameters need to check as per the customer’s requirement .The same will be available under COMMS/IM64
If you still face the issues in the communication in your SAS, thanks to contact our customer care center for support with the below information for detail analysis
a) Both ends .studioarch file with complete setting,PSL, Logs(DR/FR/ER) & MCL files ),
b) Communication traces captured by recently during issue occurred (Wireshark)
c) End to end complete differential protection scheme
d) Detailed test description with communication architecture
