How to check Network Card status
Using the Menu On/Off -> [Info] -> [Status] -> [Card] and enter the network card address in this
case it is '4'. The display will confirm:
¨
the address of the network card
¨
the 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.
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. A
time out error will also be generated for each parity/ framing error.
Errors meaning
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 point of failure, where required.
¨
Check the addresses and baud rates of the network cards of all the networked panels.
¨
It may be necessary to investigate and:
•
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 4.
On completion of the above the networked system may now be configured for network operation,
for master sectors and global controls to be actioned as per site requirements.
