3.7.6. Master Packet Repeat in MultiPoint Networks with Repeaters
The Master Packet Repeat parameter must be set in MultiPoint Repeaters because a Repeater
appears as a Master to a Slave radio.
Therefore, the Repeater sends the packet out the number of times corresponding to its own
Master Packet Repeat parameter setting. If this parameter is set improperly the reliability of the
overall network may be diminished.
Example: If a Master's Master Packet Repeat parameter setting is 3, the link between the Master
and Repeater should be robust.
If the Repeater's Master Packet Repeat parameter setting is 0, this could cause marginal links
between the Repeater and the Slaves.
The Slaves communicating through this Repeater only receive the initial packet from the Master with
no repeats.
Therefore, if the packet is not received on the first try, the Slave radio does not respond as expected.
Note: The Master Packet Repeat parameter setting in any MultiPoint Repeater must be less than
or equal to the Master's setting.
3.7.7. Max Slave Retry
Max Slave Retry
Setting Description
Default Setting 9
Options Any number between 1 and 9.
Terminal Menu (5) Edit MultiPoint Parameters > (2) Max Slave Retry
Description: l Defines how many times the Slave radio attempts to retransmit a packet to the
Master before beginning to use a back-off algorithm as defined by the Retry
Odds on page 82 setting.
l The Slave radio retries stop when the Slave receives an acknowledgment from
the Master.
3.7.8. Radio ID
Radio ID
Setting Description
Default Setting Blank
Options Any 4 digit, user-defined number.
Terminal Menu (5) Edit MultiPoint Parameters > (D) Radio ID
Description: Use this option to designate a radio with an arbitrary, user-defined, 4-digit number
that identifies the radio in Diagnostics mode.
