Document No: LT0122 F3200 Installation & Programming Manual
Network Programming

11.3 NETWORK CONFIGURATION MENU
These configuration settings determine how the F3200 communicates with other panels on
the network. In general, most settings should be left at default values. However, there may
be some settings that need to be customised for some installations.
The < and > keys allow movement between five menus NetPg1 through NetPg5.
11.3.1 NETPG1 OPTIONS
1. SID: (1-254)
This is the network address (SID number) of this F3200, allowing for the unique identification
of zones, events, and for remote controls to be sent to this F3200. The SID for any device
on the network must be a unique number between 1 and 254. It is recommended that all
Fire Alarm Panels are numbered sequentially from 1 upwards, so as to make numbering
consistent. This is because the SID is combined with the local zone number to form a
network zone number.
2. Mode : (Multidrop/Point to point)
In general, this must be left as multidrop. In some special cases, point to point mode be
may be selected, eg. a single F3200 connected to one other device. Point to Point mode
requires a full duplex data path between this panel and one other device.
3. NIC : (Yes/No)
Is set to "Yes" only if another device on the network is configured to acknowledge
broadcasts. Acknowledgment of broadcasts provides extra confirmation that a message
sent has been received. Panel throughput is reduced as the F3200 must wait for an
acknowledgement before it can transmit further messages. It is recommended that
acknowledgement of broadcasts is enabled on the network. This means that every panel
has the NIC option set to yes except for the panel doing the acknowledging (See NetPg4
option 1, section 11.3.4).
4. RX Timeout : (1-250)
Number of 5 millisecond time periods of delay before a channel is assumed to be free.
5. TX Delay : (1-250)
Scaling factor for randomised delay before transmission. Measured in 5 millisecond time
periods.
11.3.2 NETPG2 OPTIONS
1. Ack time : (1-9999)
Time to wait for Acknowledge before retransmission. Measured in 1 millisecond time
periods.
2. DUP time : (1-9000)
Time during which duplicate messages are ignored. Measured in 1 millisecond periods.
3. Leading FF : (0-250)
Number of $FF preamble characters transmitted after asserting RTS, before sending a
message.
4. Trailing FF : (0-250)
Number of $FF characters inserted after a message to ensure that the message is
transmitted by the UART before RTS is deassserted.
