Transmission Timeouts; Transmit A Broadcast - Digi XLR PRO User Manual

Networking methods
(broadcast hops) or broadcast radius values have not been depleted. If a repeated broadcast has
already been seen, the node will ignore it. The NH (network hops) parameter sets the maximum
number of hops that a broadcast will be repeated. This value is always used, unless a smaller BH value
is specified.
By default, the CE (node messaging option) parameter is set to not route broadcasts. Due to the long-
range of the XLR PRO, Digi advises you to evaluate on a per-radio basis which nodes should be
configured as repeaters. Limiting the amount of congestion and generated RF traffic provides a more
reliable network.

Transmission timeouts

When a node receives an API Tx Request while in API mode or an
Transparent mode, the time required to route the data to its destination depends on a number of
configured parameters and whether the transmission is a unicast or a broadcast.
Note The timeouts in this section are theoretical timeouts. An 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.

Transmit a broadcast

All of the routers in a network must relay a broadcast transmission.
The maximum delay occurs 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 * NN * %8
Unless BH < NH, in which case the formula is:
BroadcastTxTime = BH * NN * %8
