Transmission timeouts
When a node receives an API TX Request (API configured XLR PRO radios) or an RO timeout occurs (XLR PRO
configured for Transparent Mode) the time required to route the data to its destination depends on a number of
configured parameters, whether the transmission is a unicast or a broadcast.
Note
The timeouts in this section are theoretical timeouts and not precisely accurate. The application should pad
the calculated maximum timeouts by a few hundred milliseconds. When using API mode, Tx Status API
packets should be the primary method of determining if a transmission has completed.
Transmitting a broadcast
A directed broadcast transmission must be relayed by all routers in the network. The maximum delay would be when
the sender and receiver are on the opposite ends of the network. The NH and %H parameters define the maximum
broadcast delay as follows:
BroadcastTxTime=NH*%8
