ODIN Intercom Matrix Menu System Description 99
Round Trip Field
The Round Trip field displays approximately how long, in milliseconds, it take for a message from the intercom to be
acknowledged by the trunk master.
The round trip time reflects network delays. Since packets are not acknowledged immediately. The round trip time may be up to 50
mSec for local networks with low latencies. If the latency is excessive (several seconds or longer), the link may fail.
Packets To Field
The Packets To field display the number of packets (for example, messages) sent to the trunk master from the intercom.
Retransmits Field
The Retransmits field displays how many messages (for example, packets) needed to be retransmitted because no
acknowledgement for those packets is received from the trunk master. This can happen if a message was dropped by the network,
or if the round trip is high enough the intercom reset the message before it received the acknowledgement from the trunk master.
Packets From Field
The Packets From field displays the number of packets (for example, messages sent) from the trunk master to the intercom.
Duplicates Field
The Duplicates field displays how many messages (for example, packets) have been received by the trunk master more than once.
GPIO-16
Frame Field
The Frame field is used to select the frame to be viewed.
GPIO-16 Column
The GPIO-16 column displays the number of the GPIO-16.
Each GPIO-16 handles 16 GPIO inputs and outputs. If the system is configured for 96 relays, there will be six GPIO-16s available.
