How to check Network Card status
Using the Menu On/Off -> [Info] -> [Status] -> [Card] and enter the network card 10. The display will confirm:
¨
address of the network card
¨
address of network controller
¨
and a set of condition codes
Card 10 Is OK Fault 0:Disable 0:Warning 0

Errors
meaning
Parity
Parity is incorrect, data corrupted.
Framing
8- bit transmitted incorrectly and the data line does not return to logic 1 at the end of the transmission.
CRC
Cyclic redundancy code. When a message consisting of a number of 8 bit transmissions is sent, a calculation is
carried out to check that data corruption has not occurred.
Time out
Where an 8 bit transmission block is not fully received, the network card will time out ready to receive the next
error
message. Time out error will also be generated for each parity/ framing error.
Freeblock
Free memory blocks available to temporarily store messages waiting to be processed. The maximum number =
199, although it may drop as low as 175 - 180 on a highly populated network. A lower value may indicate a high
error value and will require rectification.
Fault Finding
¨
The communication path in a secure network alternates between end 1 (side 1) and end 2 (side 2) every minute.
¨
The network will be non secure until the last panel is connected and powered-up.
High errors
¨
Check cable lengths and type used.
¨
Check wiring, connections and earthing arrangements.
¨
Replace network card at point of failure.
¨
Check the addresses and baud rates of the input output and network cards of the networked panels.
¨
Check the network cable is correctly earthed to the equipment.
¨
It may be necessary escalate an investigation to:
•
look at the noise voltage between conductors, screen and earth.
"
Always reset the Network Card first when rechecking for errors, using [Test/Eng] -> [Card] ->[Reset] ->
Network Card 10.
The networked system may now be configured for network commands to be actioned, such as master sectors and global alarms as
per site requirement.
