How to check Network Card status
Using the
Menu On/Off
->
[Info] -> [Status] -> [Card]
and enter the network card number, usually
this is card number 6 and select
[E]
. The display will confirm the:
¨
address of the network card
¨
address of network controller
¨
and a set of condition codes
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.
Errors
meaning
Time out
error
Where an 8 bit transmission block is not fully received, the
network card will time out ready to receive the next 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 will alternate 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. Check the network cable is
correctly earthed to the equipment.
¨
Replace network card at the point of failure.
¨
Check the addresses and baud rates of the input / output and network cards of the
networked panels.
¨
It may be necessary to 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 number, normally Card 6 and select [E].
The networked system may now be configured for network commands to be actioned, such as
master sectors and global controls as per site requirements.
